Loading textbox based on data in another textbox

[Bob Bruce]

I need to load a textbox with data based on the contents of another texbox.   I want to load the unbound textbox txtRiders based on the value of the bound textbox txtOptionID.  Here's what I tried:

 

 

    Private Sub txtOptionID_ItemDataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtOptionID.ItemDataBound
       
    Dim txtOpt As Telerik.Reporting.Processing.TextBox = DirectCast(sender, Telerik.Reporting.Processing.TextBox)

         If txtOpt.Value.ToString ="1"
             txtRiders.Value = "New Item 1"
         End If

    End Sub

Your help is, as always, appreciated.

More info.

The code I sent works, but only on the last group.  The report is grouped by OptionID, the data bound to txtOptionID.  It appears that only the last instance of txtRider in the DetailSection, gets loaded.

Hello Bob,

You should always work with the processing report objects when you are in the context of an event, thus do not use definition items such as txtRiders (more info on definition vs. processing here). You can see a sample code in this help article: How do I combine values of two columns to a single TextBox?.

Thanks.  I have resolved the problem.  I am getting more comfortable with the report events and object instancing.
