The parameterized query expects the parameter '#ProductImage', which was not supplied

Here, when I try to update image in a gridview, I can update everything pretty easily. When I do not select image and try to update other fields, I get above error.
Here is my Code.
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
int productId = Convert.ToInt32(GridView1.DataKeys[e.RowIndex].Value);
TextBox productName = GridView1.Rows[e.RowIndex].FindControl("ProductTextBox") as TextBox;
TextBox description = GridView1.Rows[e.RowIndex].FindControl("DescriptionTextBox") as TextBox;
TextBox itemsInSet = GridView1.Rows[e.RowIndex].FindControl("ItemsTextBox") as TextBox;
TextBox unitPriceOwner = GridView1.Rows[e.RowIndex].FindControl("PriceOwnerTextBox") as TextBox;
TextBox unitPriceReseller = GridView1.Rows[e.RowIndex].FindControl("PriceResellerTextBox") as TextBox;
TextBox shippingCost = GridView1.Rows[e.RowIndex].FindControl("CostTextBox") as TextBox;
TextBox inOffer = GridView1.Rows[e.RowIndex].FindControl("InOfferTextBox") as TextBox;
CheckBox visible = GridView1.Rows[e.RowIndex].FindControl("VisibleCheckBox") as CheckBox;
FileUpload FileUpload1 = (FileUpload)GridView1.Rows[e.RowIndex].FindControl("FileUpload1");
Product product = new Product();
product.ProductID = productId;
product.ProductName = productName.Text;
product.Description = description.Text;
product.ItemsInSet = Convert.ToInt32(itemsInSet.Text);
product.UnitPriceOwner = Convert.ToInt32(unitPriceOwner.Text);
product.UnitPriceReseller = Convert.ToInt32(unitPriceReseller.Text);
product.ShippingCost = Convert.ToInt32(shippingCost.Text);
product.InOffer = Convert.ToBoolean(inOffer.Text);
product.Visible = visible.Checked;
if (FileUpload1.HasFile)
{
int length = FileUpload1.PostedFile.ContentLength;
product.ProductImage = new byte[length];
FileUpload1.PostedFile.InputStream.Read(product.ProductImage, 0, length);
}
else
{
ProductBL.GetImage(productId);
}
ProductBL.UpdateProduct(product);
GridView1.EditIndex = -1;
GridView1.DataSource = ProductBL.GetProducts();
GridView1.DataBind();
}
This is my Business Logic Layer code for Product.
public static void UpdateProduct(Product product)
{
string query = "UPDATE [Products] SET [ProductName] = #ProductName, [Description] = #Description, [ItemsInSet] = #ItemsInSet, " +
"[UnitPriceOwner] = #UnitPriceOwner, [UnitPriceReseller] = #UnitPriceReseller, [CategoryID] = #CategoryID, " +
"[ShippingCost] = #ShippingCost, [InOffer] = #InOffer, [ProductImage] =#ProductImage, [Visible] = #Visible WHERE [ProductID] = #ProductID";
SqlCommand cmd = new SqlCommand(query);
cmd.Parameters.AddWithValue("#ProductName", SqlDbType.Text).Value = product.ProductName;
cmd.Parameters.AddWithValue("#Description", SqlDbType.Text).Value = product.Description;
cmd.Parameters.AddWithValue("#ItemsInSet", SqlDbType.Int).Value = product.ItemsInSet;
cmd.Parameters.AddWithValue("#UnitPriceOwner", SqlDbType.Int).Value = product.UnitPriceOwner;
cmd.Parameters.AddWithValue("#UnitPriceReseller", SqlDbType.Int).Value = product.UnitPriceReseller;
cmd.Parameters.AddWithValue("#CategoryID", SqlDbType.Int).Value = product.CategoryID;
cmd.Parameters.AddWithValue("#ShippingCost", SqlDbType.Int).Value = product.ShippingCost;
cmd.Parameters.AddWithValue("#InOffer", SqlDbType.Bit).Value = product.InOffer;
cmd.Parameters.AddWithValue("#Visible", SqlDbType.Bit).Value = product.Visible;
cmd.Parameters.AddWithValue("#ProductID", SqlDbType.Text).Value = product.ProductID;
cmd.Parameters.AddWithValue("#ProductImage", SqlDbType.Image).Value = product.ProductImage;
DbUtility.UpdateDb(cmd);
}

You can check like this before update:
SqlParameter unitsParam = command.Parameters.AddWithValue("#ProductImage", SqlDbType.Image);
if (product.ProductImage == null)
{
unitsParam.Value = DBNull.Value;
}
else
{
unitsParam.Value = product.ProductImage
}

Updating DATAGRID row to save to SQL

Hi Guys I am trying to understand how to save and edited row to the database
private void BudgetGrid_RowEditEnding(object sender,
DataGridRowEditEndingEventArgs e)
{
SqlCommand gridcmd = new SqlCommand();
SqlConnection rwConn = null;
rwConn = new SqlConnection("server=localhost;" +
"Trusted_Connection=yes;" + "database=Production; " + "connection
timeout=30");
gridcmd.Connection = rwConn;
rwConn.Open();
//gridcmd.CommandText =
//"SELECT Id, Name, Quantity, Rate, Time FROM Budget";
gridcmd.CommandText =
"UPDATE Budget SET Id = #id, Name = #Name, " +
"Quantity = #Qty, Rate = #Rte WHERE Time = #Time";
SqlDataAdapter gridda = new SqlDataAdapter(gridcmd);
string strId = "#id".ToString();
int intID;
bool bintID = Int32.TryParse(strId, out intID);
string strName = "#Name".ToString();
string strQty = "#Qty".ToString();
int intQty;
bool bintQty = Int32.TryParse(strQty, out intQty);
string strRte = "#Rte".ToString();
int intRte;
bool bintRte = Int32.TryParse(strRte, out intRte);
string strTime = "#Time".ToString();
gridda.SelectCommand.Parameters.Add(
new SqlParameter("#id", SqlDbType.Int));
gridda.SelectCommand.Parameters["#id"].SqlValue = intID;
gridda.SelectCommand.Parameters.Add(
new SqlParameter("#Name", SqlDbType.VarChar));
gridda.SelectCommand.Parameters["#Name"].SqlValue = strName;
gridda.SelectCommand.Parameters.Add(
new SqlParameter("#Qty", SqlDbType.Int));
gridda.SelectCommand.Parameters["#Qty"].SqlValue = strQty;
gridda.SelectCommand.Parameters.Add(
new SqlParameter("#Rte", SqlDbType.Int));
gridda.SelectCommand.Parameters["#Rte"].SqlValue = strRte;
gridda.SelectCommand.Parameters.Add(
new SqlParameter("#Time", SqlDbType.VarChar));
gridda.SelectCommand.Parameters["#Time"].SqlValue = strTime;
DataTable griddt = new DataTable("Budget");
gridda.Fill(griddt);
gridda.UpdateCommand =
new SqlCommandBuilder(gridda).GetUpdateCommand();
BudgetGrid.ItemsSource = griddt.DefaultView;
gridda.Update(griddt);
rwConn.Close();
}
it displays fine. I can edit its but when I click on the other tab it does not update it goes back to the original data.
Most of the code I have been going through its either out dated.. or not what I am looking for.
so here is the database
and here is the app
so basically if i hit tab to the next row. under the event BudgetGrid_RowEditEnding it should update the database.. but now its not.

Just copy below codes. I've created all the thing of you and tested successfully. Rather than the first way, I tried to let you go more popular way. Therefore, it took me time to adopt..
Hope this helps you !

Your SQL syntax has to be corrected like,
SqlCommand update_comm = new SqlCommand();
update_comm.Connection = Conn;
update_comm.CommandText = "UPDATE Budget SET id= #u_id, Name= #u_name WHERE person= #psn";
var update_da = new SqlDataAdapter(update_comm);
update_da.SelectCommand.Parameters.Add(new SqlParameter("#u_id", SqlDbType.Int));
update_da.SelectCommand.Parameters["#u_id"].Value = yourintvalue;
update_da.SelectCommand.Parameters.Add(new SqlParameter("#u_name", SqlDbType.NVarChar));
update_da.SelectCommand.Parameters["#u_name"].Value = yourstringvalue;
update_da.SelectCommand.Parameters.Add(new SqlParameter("#psn", SqlDbType.NVarChar));
update_da.SelectCommand.Parameters["#psn"].Value = yourstringvalue;
var update_ds = new DataSet();
update_da.Fill(update_ds);
'UPDATE' should be used with 'SET' together.
And if you want to update the actual SQL database with the value of edited rows of DataGrid, please try this.
da.UpdateCommand = new SqlCommandBuilder(da).GetUpdateCommand();
da.Update(griddt);

SqlConnection uniConn = null;
SqlCommand cmd = null;
SqlDataAdapter sda = null;
DataTable dt = new DataTable();
uniConn = new SqlConnection(
"server=localhost;" + "Trusted_Connection=yes;" +
"database=Production; " + "connection timeout=30");
cmd = new SqlCommand("UPDATE Budget(id, Name, Quantity, Rate, Time)",
uniConn);
uniConn.Open();
sda = new SqlDataAdapter(cmd);
sda.Fill(dt);
BudgetGrid.ItemsSource = dt.DefaultView;
uniConn.Close();
Did you forget to close the connection?

ORA-01036: illegal variable name/number while updating gridview

I want to update a cell of the row in gridview. But I am getting error as
ORA-01036: illegal variable name/number
at cmd.ExecuteNonQuery()
Here is my code below:-
protected void SaveChanges(object sender, EventArgs e)
{
myConn.Open();
string excelData = Grid1ExcelData.Value;
string excelDeletedIds = Grid1ExcelDeletedIds.Value;
string[] rowSeparator = new string[] { "|*row*|" };
string[] cellSeparator = new string[] { "|*cell*|" };
string[] dataRows = excelData.Split(rowSeparator, StringSplitOptions.None);
for (int i = 0; i < dataRows.Length; i++)
{
string[] dataCells = dataRows[i].Split(cellSeparator, StringSplitOptions.None);
string mkey = dataCells[0];
string shipName = dataCells[1];
string shipCity = dataCells[2];
string shipAddress = dataCells[3];
string shipCountry = dataCells[4];
string orderDate = dataCells[5];
bool sent = dataCells[6] == "yes";
string insertUpdateQuery = "";
if (!string.IsNullOrEmpty(mkey))

}
else
{

}

cmd.Parameters.Add("#ShipAddress", OracleType.VarChar).Value = shipAddress;
cmd.Parameters.Add("#ShipCountry", OracleType.VarChar).Value = shipCountry;
cmd.Parameters.Add("#OrderDate", OracleType.DateTime).Value = orderedOn;
cmd.Parameters.Add("#Sent", OracleType.Char).Value = true;
if (!string.IsNullOrEmpty(mkey))
{
cmd.Parameters.Add("#MKEY", OracleType.Number).Value = mkey;
}
cmd.ExecuteNonQuery();
if (insertUpdateQuery != "")
{
Page.ClientScript.RegisterStartupScript(typeof(Page), "CloseScript", "alert('Data Updated succesfully');", true);
}
}
if (!string.IsNullOrEmpty(excelDeletedIds))
{
OracleCommand deleteComm = new OracleCommand("DELETE FROM Orders WHERE OrderID IN (" + excelDeletedIds + ")", myConn);
deleteComm.ExecuteNonQuery();
}
myConn.Close();
Grid1.DataBind();
}

The problem is that you are using the wrong bind variable syntax (looks like you're using SQL Server parameter binding syntax). Oracle's ADO.NET provider expects you to use a : prefix rather than a #.
So try something like this instead:
insertUpdateQuery = "UPDATE B_Order_new SET ShipName = :ShipName, ShipCity = :ShipCity, ...
And then when setting the values, you don't need to prefix it:
cmd.Parameters.Add("ShipName", OracleType.VarChar).Value = shipName;
cmd.Parameters.Add("ShipCity", OracleType.VarChar).Value = shipCity;
...
EDIT
Also, if you are binding the parameters by name, make sure you set the OracleCommand.BindByName property to true. Otherwise, the binding will be done positionally.

Record not updated in Database

I am unable to update record in my database.
my code is as follows:
private void update_Click(object sender, EventArgs e)
{
con.Open();
try
{
string strQuery = "UPDATE test_name SET Test_Name = #name, Price = #price, Lab_Price = #lprice, normal_value_child = #child, normal_value_men = #men, normal_value_women = #women, notes = #note, unit = #un, SubGroup = #sub, MainGroup = #main" +
"WHERE Test_Id = #tstID";
using (System.Data.SqlServerCe.SqlCeCommand cmdSelect = new System.Data.SqlServerCe.SqlCeCommand(strQuery, con))
{
cmdSelect.Parameters.AddWithValue("#tstID", richTextBox2.Text);
cmdSelect.Parameters.AddWithValue("#name", richTextBox1.Text);
cmdSelect.Parameters.AddWithValue("#price", richTextBox7.Text);
cmdSelect.Parameters.AddWithValue("#lprice", richTextBox8.Text);
cmdSelect.Parameters.AddWithValue("#child", richTextBox5.Text);
cmdSelect.Parameters.AddWithValue("#men", richTextBox4.Text);
cmdSelect.Parameters.AddWithValue("#women", richTextBox3.Text);
cmdSelect.Parameters.AddWithValue("#note", richTextBox9.Text);
cmdSelect.Parameters.AddWithValue("#un", richTextBox6.Text);
cmdSelect.Parameters.AddWithValue("#sub", comboBox2.Text);
cmdSelect.Parameters.AddWithValue("#main", comboBox1.Text);
cmdSelect.ExecuteNonQuery();
updatedb();
con.Close();
}
}
catch (Exception ex)
{
}
this.test_nameTableAdapter2.Fill(this.datalabDataSet14.test_name);
MessageBox.Show("Updated Successfully");
}
}
I don't understand what's the problem.

Add space before WHERE:
string strQuery = "UPDATE test_name SET Test_Name = #name, Price = #price, Lab_Price = #lprice, normal_value_child = #child, normal_value_men = #men, normal_value_women = #women, notes = #note, unit = #un, SubGroup = #sub, MainGroup = #main" +
" WHERE Test_Id = #tstID";

How to implement Edit Feature in asp.net application?

Below 2 links give the preview of my sample application.
http://img812.imageshack.us/i/image1adl.jpg/ : shows mine sample application. All fields are self explanatory (if query, let me know)
http://img834.imageshack.us/i/image2vc.jpg/ : shows, when clicked the "Edit" button from the grid, the timings are shown correctly but the order gets disturbed. (See 7:00 coming on the top and then the timings list are seen).
My Questions
How to correct the timings problem? (Link # 2)
Code for "Edit" is below
protected void lnkEdit_Click(object sender, EventArgs e)
{
int imageid = Convert.ToInt16((sender as Button).CommandArgument);
DataSet ds = new DataSet();
SqlConnection sqlconn = new SqlConnection();
sqlconn.ConnectionString = ConfigurationManager.ConnectionStrings["TestConn"].ConnectionString;
string sql = #"SELECT * FROM Images WHERE IsDeleted=0 and Imageid='"+ imageid +"'";
SqlCommand sqlcommand = new SqlCommand(sql, sqlconn);
sqlcommand.CommandType = CommandType.Text;
sqlcommand.CommandText = sql;
SqlDataAdapter da = new SqlDataAdapter(sqlcommand);
da.Fill(ds);
if (ds.Tables[0].Rows.Count > 0)
{
txtImageName.Text = ds.Tables[0].Rows[0].ItemArray[1].ToString();
chkIsActive.Checked = Convert.ToBoolean(ds.Tables[0].Rows[0]["IsActive"].ToString());
ddlStartTime.DataSource = ds;
ddlStartTime.DataTextField = ds.Tables[0].Columns["StartTime"].ColumnName.ToString();
ddlStartTime.DataValueField = ds.Tables[0].Columns["ImageId"].ColumnName.ToString();
ddlStartTime.DataBind();
ddlEndTime.DataSource = ds;
ddlEndTime.DataTextField = ds.Tables[0].Columns["EndTime"].ColumnName.ToString();
ddlEndTime.DataValueField = ds.Tables[0].Columns["ImageId"].ColumnName.ToString();
ddlEndTime.DataBind();
BindDropDownList();
IsEdit = true;
}
When i edit the existing record in the grid, i am getting the values, but the record is not being updated but added as a new record into db. I am aware that i am suppose to write update script. But where to write that?
Below the code is for the same;
protected void btnSubmit_Click(object sender, EventArgs e)

Please help!

Where do you define Bool/Bolean IsEdit? I think its value is reset on page postback, that's why it is always false and the record is being inserted. I would suggest you to use a hidden field to track this and set its value there and check the value upon insert/updating. Finally it will be something like...
if (ds.Tables[0].Rows.Count > 0)
{
//your code
hiddenField.Value = "true"; // you can set default value to false
}
and then after
if (hiddenField.Value == "false")
{
cmd.CommandText = "Insert into Images(FileName,FileContent,IsDeleted,IsActive,StartTime,EndTime) values (#img_name, #img_content,#IsDeleted,#IsActive,#StartTime,#EndTime)";
}
else
{
cmd.CommandText = "Update Images set FileName=#img_name, FileContent=#img_content, IsDeleted= #IsDeleted,IsActive= #IsActive, StartTime=#StartTime,EndTime=#EndTime";
}
