Update query updates all records except the name

I am stuck with an issue with updating. When I open my Windows form developed in C# using SQL, the update updates all fields but not the name. Could you tell me what I did wrong?
Here is my code
public void cc()
{
cbBname.Items.Clear();
SqlCommand cmd = new SqlCommand();
cmd.CommandType = CommandType.Text;
cmd.CommandText = "select * from BkhurData";
db.ExeNonQuery(cmd);
DataTable dt = new DataTable();
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(dt);
foreach (DataRow dr in dt.Rows)
{
cbBname.Items.Add(dr["Name"].ToString());
}
}
private void BkhurUpdate_Click(object sender, EventArgs e)
{
SqlCommand cmd = new SqlCommand();
cmd.CommandType = CommandType.Text;
cmd.CommandText = "update BkhurData set Name='" + tbBpname.Text + "',Details='" + tbBpdetails.Text + "',Price='" + tbBpprice.Text + "',Size='" + tbBpsize.Text + "', Quantity ='"+tbBpquantity.Text+"' where Name = '" + tbBpname.Text + "'";
db.ExeNonQuery(cmd);
tbBpname.Text = "";
tbBpdetails.Text = "";
tbBpprice.Text = "";
tbBpsize.Text = "";
tbBpquantity.Text = "";
cc();
MessageBox.Show("updated successfully");
}

You are updating the Name where the Name equals tbBpname.Text so it will not change the name for row you are updating.
private string originalName;
public void cc()
{
cbBname.Items.Clear();
SqlCommand cmd = new SqlCommand();
cmd.CommandType = CommandType.Text;
cmd.CommandText = "select * from BkhurData";
db.ExeNonQuery(cmd);
DataTable dt = new DataTable();
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(dt);
foreach (DataRow dr in dt.Rows)
{
cbBname.Items.Add(dr["Name"].ToString());
originalName = dr["Name"].ToString()
}
}
private void BkhurUpdate_Click(object sender, EventArgs e)
{
SqlCommand cmd = new SqlCommand();
cmd.CommandType = CommandType.Text;
cmd.CommandText = "update BkhurData set Name='" + tbBpname.Text + "',Details='" + tbBpdetails.Text + "',Price='" + tbBpprice.Text + "',Size='" + tbBpsize.Text + "', Quantity ='"+tbBpquantity.Text+"' where Name = '" + originalName+ "'";
db.ExeNonQuery(cmd);
tbBpname.Text = "";
tbBpdetails.Text = "";
tbBpprice.Text = "";
tbBpsize.Text = "";
tbBpquantity.Text = "";
cc();
MessageBox.Show("updated successfully");
}
Please note you should use SqlParameters and not build the query as a string.

Deleting mysql table entry with C#

Basically, what I want to delete an entry form a dataviewtable which pulls data through from MySql. I thought this would be done fairly by effectively copying the modify code and substituting it for 'DELETE'. However, from the code below, you can clearly see that hasn't worked. I will copy most of my code for you:
private void button1_Click(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection("Data Source=DESKTOP-HNR3NJB\\mysql;Initial Catalog=stock;Integrated Security=True");
var sqlQuery = "";
if (IfProductsExists(con, textboxProductID.Text))
{
con.Open();
sqlQuery = #"DELETE FROM [Products] WHERE [ProductID] = '" + textboxProductID.Text + "'";
SqlCommand cmd = new SqlCommand(sqlQuery, con);
cmd.ExecuteNonQuery();
con.Close();
}
else
{
MessageBox.Show("Record doesn't exist!", "ERROR:", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
//Reading Data
LoadData();
}
So that's the delete button's code now for the add button and load data function
Add button:
private void button2_Click(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection(#"Data Source=DESKTOP-HNR3NJB\mysql;Initial Catalog=stock;Integrated Security=True");
//insert logic
con.Open();
if(textboxProductID.Text == "" || textboxProductName.Text == "")
{
MessageBox.Show("You have to enter either a product ID or product name", "Error:", MessageBoxButtons.OK, MessageBoxIcon.Error);
return;
}
else
{
bool status = false;
if (comboboxStatus.SelectedIndex == 0)
{
status = true;
}
else
{
status = false;
}
var sqlQuery = "";
if (IfProductsExists(con, textboxProductID.Text))
{
sqlQuery = #"UPDATE [Products] SET [ProductName] = '" + textboxProductName.Text + "' ,[ProductStatus] = '" + status + "' WHERE [ProductID] = '" + textboxProductID.Text + "'";
}
else
{
sqlQuery = #"INSERT INTO [Stock].[dbo].[Products] ([ProductID],[ProductName],[ProductStatus]) VALUES
('" + textboxProductID.Text + "','" + textboxProductName.Text + "','" + status + "')";
}
SqlCommand cmd = new SqlCommand(sqlQuery, con);
cmd.ExecuteNonQuery();
con.Close();
textboxProductID.Clear();
textboxProductName.Clear();
LoadData();
}
}
LoadData function:
public void LoadData()
{
SqlConnection con = new SqlConnection(#"Data Source=DESKTOP-HNR3NJB\mysql;Initial Catalog=stock;Integrated Security=True");
//reading data from sql
SqlDataAdapter sda = new SqlDataAdapter("Select * From [stock].[dbo].[Products]", con);
DataTable dt = new DataTable();
sda.Fill(dt);
dataGridView1.Rows.Clear();
foreach (DataRow item in dt.Rows)
{
int n = dataGridView1.Rows.Add();
dataGridView1.Rows[n].Cells[0].Value = item["ProductID"].ToString();
dataGridView1.Rows[n].Cells[1].Value = item["ProductName"].ToString();
if ((bool)item["ProductStatus"])
{
dataGridView1.Rows[n].Cells[2].Value = "Active";
}
else
{
dataGridView1.Rows[n].Cells[2].Value = "Deactive";
}
}
}
You're going to need the IfProductsExists method too:
private bool IfProductsExists(SqlConnection con, string productCode)
{
SqlDataAdapter sda = new SqlDataAdapter("Select 1 From [Products] WHERE [ProductID]='" + productCode + "'", con);
DataTable dt = new DataTable();
if (dt.Rows.Count > 0)
return true;
else
return false;
}
It's going to be an inventory system that's going to be used at work for the sale and inventory management of IT equipment.

Edit Not Working After GridView Filter By Drop Down

I am stuck at editing editing point after filtering the GridView By a drop down list(i.e dropdown is placed outside the gridview).
When I click on editlink after filtering the gridview it makes the starting rows of the whole grid editable.
I want to do this in ASP.NET instead of J-Query Or Ajax.!
Any One , Please Help me on this???

Add validation on GridView row in ASP.NET

i dont have an edit template. is it possible for me to add validations on my text box in grid view during edit mode?
It updates the edited fields and works fine, but when I type in special characters, it is still being accepted. How can I validate those editableTextBoxes and prevent the user from entering invalid input?
UPDATE

why it get old dataset
