[Solved] Trying to get a value from a linkbutton...

[Kevin J]

Hello,

  In my codebehind I am creating a Radgrid and adding the columns to the grid.  One of those columns is a GridButtonColumn.  The code looks like so...

                    Dim clmbtnGRDMAIN1 As New Telerik.Web.UI.GridButtonColumn
                    clmbtnGRDMAIN1.DataTextField = rowCOLUMN.FIELDNAME
                    clmbtnGRDMAIN1.HeaderText = rowCOLUMN.EXTERNAL_READABLE1
                    clmbtnGRDMAIN1.UniqueName = rowCOLUMN.FIELDNAME
                    clmbtnGRDMAIN1.HeaderStyle.Width = rowCOLUMN.GRIDWIDTH
                    clmbtnGRDMAIN1.CommandName = "TEMPID"
                    grdMAIN1.Columns.Add(clmbtnGRDMAIN1)

 

 

 

 

This works fine, it creates the button with the proper information.  But what I want to do, is that after a user clicks on the link button, gather the value.

The Telerik example says to put some code in the ItemCreated event.  Such as this...

 

 

 

 

        If e.Item.ItemType = Telerik.Web.UI.GridItemType.Item Then
            Dim item As Telerik.Web.UI.GridDataItem
            item = e.Item
            Dim LinkButton1 As LinkButton
            LinkButton1 = item("TEMPID").Controls.Item(0)
            LinkButton1.CommandArgument = e.Item.ItemIndex.ToString()
        End If

 

 

 

 

This works and the index is correct.

But, when I try to get the value in the ItemCommand event, I get nothing.  The code is here...

            Dim index As Integer = Convert.ToInt32(e.CommandArgument)

            Dim item As Telerik.Web.UI.GridDataItem = grdMAIN1.Items(index)

 

 

 

 

 

 

And if I then do a Response.Write(item("TEMPID").Text, -1)  it comes up with a space when it should contain a string of numbers.

Anyone have any idea what I'm doing wrong or how I can get this value properly?  I'm having a heck of a time trying to do this.  I feel as though it should be easier to get a value out of a link.

Thanks
Kevin

Hi Kevin,

You can check for the CommandName and directly access the GridDataItem in the ItemCommand event as shown below.

VB:

    Protected Sub RadGrid1_ItemCommand(ByVal source As Object, ByVal e As GridCommandEventArgs)

        If e.CommandName = "TEMPID" Then
            'to get the GridDataItem
            Dim item As GridDataItem = DirectCast(e.Item, GridDataItem)

            'to get the text of the clicked buuton
            Response.Write(DirectCast(e.CommandSource, LinkButton).Text)
        End If
   End Sub

Thanks
