Delete row in GridView using Two DataKeys in condition - asp.net

Question

I want to delete a row in GridView and database as well.. I already have a stored procedure for the delete, the method is also created, but my problem is how can i use Two datakeys for my where clause. I've search and saw a lot of answers but they are using CommandArgument and that is applicable only in 1 datakeys.
I want something like this.
DELETE FROM TableName WHERE ID = Variable1 AND Name = Variable2
What i want is how can i retrieve the values of 2 datakeys in GridView if i set DataKeys like: DataKeys="ID, Name"
Any help would be appreciated.
Thanks

Answer 1

(if I correctly understood you)
stored procedure
Create Procedure [dbo].[Procedure_Name](
#Variable1 type(),
#Variable2 type() --you can add as many variables as you want, but then you have to add them in c# code as a parameters.
) as
delete from Table_Name
where Table_Name.Variable1 = #Variable1 AND Table_Name.Variable2 = #Variable2
with button in aspx code
<asp:Button ID="btnDeleteSomething" runat="server" Text="Delete Something" OnClick="btnDeleteSomething_Click"/>
then in c# codebehind
protected void btnDeleteSomething_Click(object sender, EventArgs e)
{
using (SqlConnection cn = new SqlConnection(ConfigurationManager.ConnectionStrings["DB_NAME"].ConnectionString))
{
SqlCommand cmd = new SqlCommand("Procedure_Name", cn);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Connection.Open();
cmd.Parameters.Add("#Variable1", SqlDbType.VarChar, 70(its example with varchar)).Value = Variable1.Text(every Textbox, or label, or dropdownlist)
cmd.Parameters.Add("#Variable2", SqlDbType.Int).Value = Session["UserID]" - For example if u want do delete with parameter focused on user;
try
{
int rows = cmd.ExecuteNonQuery();
}
catch (Exception ex)
{
Label1.Text = ex.Message;
}
}
}
And it works fine without Datakeys at all. If u want to do it "with" then u have to add ControlParameter in your SqlDataSource. Hope it's going to help you.

Finally i found the solution on this link:
http://www.aspsnippets.com/Articles/Using-Multiple-DataKeyNames-DataKeys-in-ASPNet-GridView-with-examples.aspx
here is what exactly im looking for..
Dim rowIndex As Integer = TryCast(TryCast(sender, ImageButton).NamingContainer GridViewRow).RowIndex
Dim ID As Integer = Convert.ToInt32(GridView1.DataKeys(rowIndex).Values(0))`
Dim Name As String = GridView1.DataKeys(rowIndex).Values(1).ToString()`
