No Documentation on toggleCssClass

I was trying various ways to change style at print time. Setting media to print didn't get me what i wanted. When debugging in Firefox i noticed that the grid control has a toggleCssClass method but i can't find any doc on it. Does this mean i can change CssClass in Javascript so it can be set before i print the page and then reset ti after print?

Radgrid Sort problem

Hi,
I have a RadGrid and a button on a page. I bind the grid to a datatable on the button click event.
The problem I face is once I sort certain column in certain order by clicking on the column header, It maintains this state even after I bind the grid to a new datasource. So how do i remove the old sort order on the grid and reset the grid to it's actual state while I rebind the grid to a new datasource.

thnx
madhu

Export hidden GridBoundColumns

Hey there,

I have several GridBoundColumns that are set to hidden. They only display in the edit form view, but I would like them to show up when I export to Excel, PDF and Word. I've tried the following, but I'm not even sure if it's the right approach:

    
            foreach (GridColumn gc in mlRadGrid.MasterTableView.Columns) 
        
            { 
        
                 gc.Visible = true; 
        
            }

Any help would be much appreciated!

-Derek

[Solved] Collapse Group throws 'Specified argument was out of the range of valid values.'

Hi

I am using the example code Collapse group and it throws an ArgumentOutOfRageExceptiopn (Specified argument was out of the range of valid values). I believe it is the Controls(0). My Grouping is static, defined in Asp code. It works with out this code. I have Telerik Asp.Net AJAX 2008 3 1105 dll's.

Partial Class Dispatcher_MismatchedReport
    Inherits System.Web.UI.Page
    '
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If (Not (IsPostBack)) Then
            CollapseAll()
        End If
    End Sub ' Page_Load
    '
    Private Sub CollapseAll()
        Dim item As GridItem
        For Each item In RadGrid1.MasterTableView.Controls(0).Controls
            If TypeOf item Is GridGroupHeaderItem Then
                item.Expanded = False
            End If
        Next item
    End Sub ' CollapseAll

When Clicking the page arrorow or pg Number, Index Out of Range Error returns

Here is my environment Specs:

ASP.NET 2.0
Microsoft Windows XP Professional Version 2002 SP2
IE V 7
Telerik Q2 2008
C#

I have a radgrid that has more than one page of data to show, the data on the page is being filled correctly, and I am limiting it to 20 records per page. I am using both the numbers href links to page through the grid and the arrow, as more data is available to be shown. When I click on the page number or arrow to page through the data in the rad grid I get the following error (also in green where it happens on my code behind snippet down below):

Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index

My debug triggers the error on the codebehind on this line, in the rgUsers_ItemCommand() when I try to page to the next 20 records:
string sUserName = e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["UserName"].ToString();

Do I need to do a conditional check to make sure that the rgUsers table has a row count greater than zero? Or is there some property I am not using to allow this? My dataset returns 30 users so I expect to see at least 10 users on page 2 of the radgrid.

Code from the aspx Page:
