使用存储过程而不是使用SqlDataSource更新和删除GridView ASP.NET C＃中的行

Question

I have a GridView to manage my products. I have used store procedure to set data source for it. I also use AutoGenerateDeleteButton property for deleting each row of my GridView and now I want to use a stored procedure to delete the rows of my GridView when I click on "Delete" LinkButton. I tried some tutorial in other forum about ASP.NET but nothing happens.

Thanks

You can use item command. On item command you can pass the id of the row you want to delete as a command argument call your delete stored procedure and then rebind the datasource on the gridview using your select stored procedure.

<asp:LinkButton runat="server" OnCommand="Delete_Command" CommandName="Delete" CommandArgument='<%# Eval("DeleteRowID") %>'></asp:LinkButton>

VB.NET

Protected Sub Delete_Command(sender As Object, e As CommandEventArgs)  
If e.CommandName.ToString = "Delete" Then 
Dim DeleteRowId As String = e.CommandArgument.ToString 
'call procedure here and pass argument delete row id 
'ExambleGridView.DataSource= Call procedure here to get the datasource 
ExambleGridView.DataBind()
End If
End Sub

C#

  protected void Delete_Command(object sender, CommandEventArgs e)
    {
        if (e.CommandName.ToString == "Delete") {
            string DeleteRowId = e.CommandArgument.ToString();
            //Call Procedure here to delete row
            ExampleGridview.Datasource=//Call Procedure here to get the datasource again
            ExampleGridView.Databind()
        }
    }
