Making a check box in the grid column invisible.

Hello All,
I have a column in the grid view with Checkboxes. Now my requirement is that i need to make some of the check boxes visible or invisible while binding the RadGridView. I am not able to figure out a way of doing it. Any help would be greatly appreciated.
''' <remarks></remarks>
   Private Sub RadGridViewBrokenRuleMessages_CellFormatting(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.CellFormattingEventArgs) Handles RadGridViewBrokenRuleMessages.CellFormatting
   If e.CellElement.ColumnIndex = 2 Then
   If Me.RadGridViewBrokenRuleMessages.CurrentRow.Cells(0).Value.ToString().ToUpper(System.Globalization.CultureInfo.CurrentCulture) = "1" Then
   e.CellElement.ColumnInfo.ReadOnly = True
   Else
   e.CellElement.ColumnInfo.ReadOnly = False
   End If
   End If
   End Sub

Is it possible to do that in here. Also if you can tell me where to do that or some sample on where to do that would be very helpful.

First RadGridView fires second SortChanged

I have two radgridviews in a user control. When a column in the first grid is clicked, it fires the SortChanging and SortChanged on the second grid. The second grid fires the correct correct event. Also, the first grid changes the sort direction arrow of the second grid. Does anyone know what's going on and how to I stop this behavior?

WinForms look & feel.

Hi,

Could You please provide Theme for WinForms style (I couldn't found one).

I was trying to achieve that using Visual Style Builder, but effect wasn't well rounded, even that I've spent some time on that.

The problem I'm facing is that I'm using RadGridView as an extension for a WinForm based project and it don't fit in well.

Another issue is that WinForms looks a little different on differents OS (XP, Windows 7) while RadGridView looks always exactly the same.

Regards.

RadCalendar.FocusedDate not showing in the view area

I have a RadCalendar set to a focused date, say 1/15/11 , but after i use the navigate button to move it to Feb and then bring it up again, it shows the month of Feb in the view instead of Jan (where focused date is 1/15/11). Do i have to do anything else to show the focused date on the calendars view.

cal_Dates.SelectedDate = (

DateTime)gv.Rows[e.RowIndex].Cells["SyDate"].Value; //eg- 1/15/11

cal_Dates.FocusedDate = cal_Dates.SelectedDate;

Thanks in advance for any help.

Gridview performance with grouping very slow

Hey there, having a performance issue when grouping is enabled. I do not believe it is the grouping logic, but perhaps a drawing issue. I have about 1800 items of 10 columns that are sorted and grouped (about 12 groups). When grouping is off, it runs very fast. With grouping on, it is painfully slow reacting to commands and changes in the bindinglist. However... if I keep most groups collapsed it runs fast again, which is what leads me to believe it may be redrawing (formatting, etc.) rows that are not visible to the user.

For now I will default the groups to collapsed, but would love some feedback on handling this performance issue when all groups are opened. I can only imagine a user with 5000+ items.

Thanks!

issues with ribbonbar and form theme

I had a radform with breeze extended theme. The I added a ribbonbar and it asked me to activate the radribbonbarform behaviour. But it told me that if i deleted the control it would reverse the automatically.

Now, I deleted the ribbonbar but the theme in the form and in all the other controls don't show the style ("breeze extended"). What can i do about it?

thanks a lot

Sort descriptors not working after upgrading to 2010.3 SP1

Hi there.

A few days ago, I upgraded from version 2010.3.1109 of the Windows Forms controls to version 2010.3.1215 (SP1). This was done to fix an issue with the RadButton.

However, now my sort descriptors I have added to a RadGridView are not being respected. Below is the code I am using which was working before the upgrade.

private void sortGrid()

{

int sortOrder = byBradFordRadioButton.ToggleState == Telerik.WinControls.Enumerations.ToggleState.On ? 0 : 1;

dataGrid.SortDescriptors.Clear();

if ( sortOrder == 0 )

{

dataGrid.SortDescriptors.Add(new SortDescriptor("Bradford Factor", ListSortDirection.Descending));

// select the first row

dataGrid.setSelectedRowIndex(0);

}

else

{
