I am trying to update gridview. Here, I have used 3 tier architecture method.
Here is my GridView.
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="4" DataKeyNames="ResllerID"
ForeColor="#333333" GridLines="None" OnRowDeleting="DeleteRecord" EmptyDataText="There are no data records to display."

Here is my code: I am getting error ResellerBL.UpdateReseller(resellerId, name.Text, mobileNumber.Text, referenceNumber.Text); It says No Overload for method which takes 4 arguments
protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
GridView1.EditIndex = e.NewEditIndex;
GridView1.DataSource = ResellerBL.GetResellers();
GridView1.DataBind();
}
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
int resellerId = Convert.ToInt32(GridView1.DataKeys[e.RowIndex].Value);
TextBox name = (TextBox)GridView1.Rows[e.RowIndex].Cells[2].Controls[0];
TextBox mobileNumber = (TextBox)GridView1.Rows[e.RowIndex].Cells[3].Controls[0];
TextBox referenceNumber = (TextBox)GridView1.Rows[e.RowIndex].Cells[4].Controls[0];
ResellerBL.UpdateReseller(resellerId, name.Text, mobileNumber.Text, referenceNumber.Text);
GridView1.EditIndex = -1;
GridView1.DataSource = ResellerBL.GetResellers();
GridView1.DataBind();
}
ResellerBL code:
public static void UpdateReseller(Reseller reseller)
{
string query = "UPDATE [Resellers] SET [ResellerName] = #ResellerName, [ReferenceNumber] = #ReferenceNumber WHERE [ResellerID] = #ResellerID";
SqlCommand cmd = new SqlCommand(query);
cmd.Parameters.AddWithValue("#ResellerName", SqlDbType.Text).Value = reseller.ResellerName;
cmd.Parameters.AddWithValue("#MobileNumber", SqlDbType.Text).Value = reseller.MobileNumber;
cmd.Parameters.AddWithValue("#ReferenceNumber", SqlDbType.Text).Value = reseller.ReferenceNumber;
cmd.Parameters.AddWithValue("#ResllerID", SqlDbType.Text).Value = reseller.ResllerID;
DbUtility.UpdateDb(cmd);
}
You are calling it with four arguments:
ResellerBL.UpdateReseller(resellerId, name.Text, mobileNumber.Text, referenceNumber.Text);
But it only accepts one:
public static void UpdateReseller(Reseller reseller)
Two options are
Create a new reseller object and pass that:
.
var myreseller = New Reseller();
myresller.Id = resellerId;
//etc
ResellerBL.UpdateReseller(myreseller);
OR
Modify the (or add an overloaded) method to take the four arguments:
.
public static void UpdateReseller(int resellerId, string resellerName, string resellerMobile, string resellerRefNum)
Your UpdateReseller method takes a single parameter: A reseller.
If you want to be able to pass individual parts to the method, you need to modify the signature or create an overload with the appropriate parameters.

I have a grid view control in my page that indexes all the Lecture Contents. I have added a Text Box control and a Link Button. But for the Lectures that have no Content yet, the Grid View does not appear.
Have tried many references, as a result the footer has appeared but I am not able to insert data using the Controls in the footer.
My main objective is to make the Controls behave same in both scenarios.
Here is the Grid View Code.
`<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" EmptyDataText="No Contents found for this lecture." ShowFooter="true" HeaderStyle-Wrap="false" Width="70%" CssClass="Grid" AlternatingRowStyle-CssClass="alt" PagerStyle-CssClass="pgr" OnSelectedIndexChanged="GridView1_SelectedIndexChanged">

and the code behind functions for grid view.
`protected void Page_Load(object sender, EventArgs e){
if (Session["fac_username"] != null)

String username = Convert.ToString(Session["fac_username"]);

command.Parameters.AddWithValue("#lecc_contents", ((TextBox)GridView1.FooterRow.FindControl("txtcontent")).Text);
command.ExecuteNonQuery();
con.Close();
lblmsg.Text = "New Course Successfully Created..!";}`
DataAccessLayer class's getAllConents() method is here.
`public class AllContents
{
public long lecc_id { get; set; }
public string lecc_contents { get; set; }
}
public class DataAccessLayer
{
public static List<AllContents> getAllContents( int lecID){
List<AllContents> listAll = new List<AllContents>();
string cs = ConfigurationManager.ConnectionStrings["ILMSConnectionString"].ConnectionString;
using (SqlConnection con = new SqlConnection(cs))
{
SqlCommand com = new SqlCommand("select lecc_id, lecc_contents from uni_lect_content, uni_lectures, uni_offered_courses where uni_lect_content.lecc_id = uni_lectures.lec_id and uni_lectures.cours_offer_id = uni_offered_courses.cours_offer_id and lecc_id = '"+lecID+"'", con);
con.Open();
SqlDataReader rdr = com.ExecuteReader();
while (rdr.Read())
{
AllContents obj = new AllContents();
obj.lecc_id = Convert.ToInt32(rdr["lecc_id"]);
obj.lecc_contents = rdr["lecc_contents"].ToString();
listAll.Add(obj);
}
}
return listAll;
}`
Help me out of this situation.
Thanks in advance.

I have a table with 100 record
This is my Gridview I have two buttons add and delete(on Delete buttonClick particular record should be deleted from database) like, I clicked on record number 35(record number 35 should be deleted) but instead record number 1 is being deleted everytime.
public void delete()
{
foreach (GridViewRow g in GridView1.Rows)
{
Label lblname = (Label)g.FindControl("lblname");
Button btnde = (Button)g.FindControl("btndelete");
//Response.Redirect("cs.aspx");
SqlCommand cmd = new SqlCommand("delete from clientrequest where client_name='" + lblname.Text + "'", con);
con.Open();
cmd.ExecuteNonQuery();
Response.Redirect("welcome.aspx");
con.Close();
}
}
protected void btndelete_Click(object sender, EventArgs e)
{
delete();
GridView1.Visible = false;
}
This is my CS code.
It's because on delete you are deleting record using foreach loop which is not a good way to do. You could try out this:
public void delete(string Name)
{
SqlCommand cmd = new SqlCommand("delete from clientrequest where client_name='" + Name + "'", con);
con.Open();
cmd.ExecuteNonQuery();
Response.Redirect("welcome.aspx");
con.Close();
}
And on Delete button click find the particular row and send it to delete Method
protected void btndelete_Click(object sender, EventArgs e)
{
Button btn = sender as Button;
GridViewRow gvr = (GridViewRow)btn.NamingContainer;
string name = ((Label)gvr.FindControl("lblname")).Text;
delete(name);
GridView1.Visible = false;
}
Note: Also you could write your redirection inside button click event on basis of delete method return.
You can find your Label control position and get their value, then delete from database. It will work fine.
public void delete()
{
foreach (GridViewRow g in GridView1.Rows)
{
if(g.RowType == DataControlRowType.DataRow)
{
Label lblname = (Label)g.FindControl("lblname");
SqlCommand cmd = new SqlCommand("delete from clientrequest where client_name='" + lblname.Text + "'", con);
con.Open();
cmd.ExecuteNonQuery();
Response.Redirect("welcome.aspx");
con.Close();
break;
}
}
}
This is what I have done for nested gridview :
The jQuery I have used to maintain this show hide is as:
<script type="text/javascript">
// Method for managing opening of gridview on + image and - image
$("[src*=plus]").live("click", function() {
$(this).closest("tr").after("<tr><td></td><td colspan = '999'>" + $(this).next().html() + "</td></tr>")
$(this).attr("src", "../Image/minus.gif");
});
$("[src*=minus]").live("click", function() {
$(this).attr("src", "../Image/plus.gif");
$(this).closest("tr").next().remove();
});
</script>

On server side this is what I am doing:
protected void GridView3_RowEditing(object sender, GridViewEditEventArgs e)
{
DataSet ds = new DataSet();
tBL objBL = new tBL();
GridViewRow editedRow = GridView1.Rows[e.NewEditIndex];
//now search row for your control...
GridView GridView3 = (GridView)editedRow.FindControl("GridView3");
GridView3.EditIndex = e.NewEditIndex;
objtxtToTableBL.ViewBL(dt);
GridView3.DataSource = dt;
GridView3.DataBind();
}
protected void GridView3_RowCancelling(object sender, GridViewCancelEditEventArgs e)
{
GridView1.EditIndex = -1;
}
protected void GridView3_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
}
I am binding the nested gridview on rowdatabound of GridView1 and that works fine.
The problem with all this is when I click on the edit button of innergridview(child) it get hide as the page postback .
What should I do so that when I click on its edit button the child gridview remains open and it gets hides only when I click on minus button. Please help it has already taken 3 days of mine.
I am trying to make an editable GridView, and when RowUpdating is called the values I get from the TextBoxes are the old values and not the new ones.

Thanks!
Try this
protected void GVProducts_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
//your code
if (!abort)
{
connection = new Connect(Server.MapPath("App_Data/ado1.mdb"));
OleDbCommand cmd = new OleDbCommand();
cmd.CommandText = "Update Products Set amount=" + amount + ", minAmount=" + minAmount + " Where phoneId=" + id;
cmd.ExecuteNonQuery();//OR "connection.ChangeDatabase(cmd);" if it updates your database
products = connection.GetData("Select * From Products", "Products");
GVProducts.EditIndex = -1;
GVProducts.DataSource = products;
GVProducts.DataBind();
UpdateGVlabel();
MessageBox.Show("המכשיר נערך בהצלחה!");
}
}
The problem was you were calling connection.ChangeDatabase(cmd); to update your database after fetching data from table like this products = connection.GetData("Select * From Products", "Products"); hence you always got old values from your db and values in your db also got updated too..
Also add this GVProducts.DataBind(); after providing datasource GVProducts.DataSource = products; to bind the grid.
Write The code in the row updating
int i=convert.toint32(e.NewValues["Standard"])
IsPostBack() is the answer. We have to check if the Page is posted back or not. If not, then we will bind the Grid.
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindGrid();
}
}

A part of this should be done at RowDataBound also.
Here is some sample code
private static DataSet ds;
private const string query = "select * from tblcountrynames";
protected void grdViewCInfo_RowEditing(object sender, GridViewEditEventArgs e)
{
grdViewCInfo.EditIndex = e.NewEditIndex;
//guessing that this is your databind event
dbLoad();
}
protected void grdViewCInfo_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowState == DataControlRowState.Edit)
{
//your ddl
DropDownList ddl = (DropDownList)e.Row.FindControl("ddlCountry");
PopulateCountries(ddl, query);
//grdViewCInfo.Rows[e.NewEditIndex].Cells[4].Controls.Add(ddl);
}
}
private void PopulateCountries(DropDownList ddl, string query)
{
if(ds!= null && ds.Tables[0].Rows.Count >0)
MySqlConnection objMycon1 = new MySqlConnection(strProvider);
//commenting open; as adapter doesn't need connection to be open
//objMycon1.Open();
MySqlCommand cmd1 = new MySqlCommand(query, objMycon1);
MySqlDataAdapter da = new MySqlDataAdapter(cmd1);
ds = new DataSet();
da.Fill(ds);
objMycon1.Close();
objMycon1.Dispose();//comment if objMycon1 is not IDisposible
}
if (ds.Tables[0].Rows.Count > 0)
{
ddl.DataSource = ds;
ddl.DataTextField = "Name";
ddl.DataValueField = "ID";
ddl.DataBind();
}
}
This is how it should be done.
Hope this helps.
What does (DropDownList)grdViewCInfo.Rows[e.NewEditIndex].Cells[4].FindControl("ddlCountry"); return , is ddl set?
I reckon not. Perhaps there is no "ddlCountry" control in that cell.
Its a curious coincidence that the line,
//grdViewCInfo.Rows[e.NewEditIndex].Cells[4].Controls.Add(ddl);
is commented out below.
Do you have a drop down list in your EditItemTemplate?
Edit: I don't think you are actually in edit mode in the RowEditing event. If you move your code down to the RowCommand,
Then check for the Edit command. Wrap your code in something like,
if(e.CommandName == "Edit")
{
// do your edit here.
}
Though keep your grdViewCInfo.EditIndex = e.NewEditIndex; line, as you need that there.
