This is not really a question, but a suggestion that I think the RadTextBox control should have.

Hi,

I need to find the id of the data items to be bound on radgrid1_ItemCreated.
Please refer to image attached with this post and code block below:



I need to find the id on this item created event for all data being bind to the grid and pass those ids to database to validation & checks.
So what will be code for
ID ......


Thanks,
Awadh

Hello, this is my code for bind a dropdowlist in ItemTemplate that has a Bind("field")

it's work fine, but in Edit Mode one time in    
list.DataSource = dsDropDown
give the error:

    {"Object reference not set to an instance of an object."}
   
Then in I'm using a catch for this error, and all is fine.

Do you know a solution for don't use the catch?

  Protected Sub RadGrid1_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemCreated

    If (TypeOf e.Item Is GridDataItem AndAlso e.Item.IsDataBound) Then

      Try
        Dim dsDropDown As New DataSet()
        OleDbCnn = New Data.OleDb.OleDbConnection(Session("CONNECT_DBS"))
        Dim item As GridDataItem = e.Item
        Dim list As DropDownList = item.FindControl("DDL_AREA_GEOGRAFICA_NAME")
        OleDbSql = Area_Geografica_Code()
        Dim OleDbDad As New Data.OleDb.OleDbDataAdapter
        OleDbDad = New Data.OleDb.OleDbDataAdapter(OleDbSql, OleDbCnn)
        OleDbDad.Fill(dsDropDown)
        list.DataSource = dsDropDown
        list.DataTextField = "NAME"
        list.DataValueField = "CD_CODE"
      Catch ex As Exception
        ex.Message.ToString()
      End Try

    End If

  End Sub

Thanks for any help

Hi

I'm having to create an admin form with a list of roles down the left and privilages across the top. At each intersection there will be a checkbox.

Would this be a suitable applcation for the listview control?

If yes do you have any examples as I'm struggling a bit, but it would help knowing it is possible before I spend too much time on it.

My original route was / is the use of nested repeaters.

Hi

Is it possible to only make some columns in a RadGrid filterable? (I have some hyperlinks that it doesn't make sense to filter).

Also, is it possible to make filtering non case sensitive?

Re
Dennis

Per this thread we realize there is assistance available to upgrade skins, is it possible for you to provide additional upgrade steps in the "Universal migrator" or can we send our two skins to you for upgrade?

Thank you,

I'm new to using Telerik ASP.net AJAX treeview control. The problem I'm facing is whenever I do a nodeEdit it does fires the code behind RadTreeView1_NodeEdit event but, when the page reappears it will have 2 treeview controls. One having the old data and the other having the new updated data. I'm updating the database table and repopulating the tree when the database write is complete.

Please let me know how to solve this issue.

Thanks

Is there an easy way to get unformatted HTML content from the editor? I am saving to a database don't want any tabs or spaces in there. I am looking for a way to do this without using a content filter and was wondering if there is some property that can facilitate this.

Hello,

I have a RadList populated by an SQLDatasource that looks like this:


Here is the code for my RadListBox:


When I try to run this, the Objective name shows up as it is supposed to, but the TopicName and CategoryName don't display in the list (it is empty in those areas).  I have this in my codebehind:


Can anyone tell me what I'm missing?  This is urgent, as it is for a project that is due very soon.  Help! :)
