RadTreeNode.Nodes.Clear() scrolls RadTreeView to first node

Hi,

When using a node's Nodes.Clear() method the tree view scrolls up to the top and shows the tree view's first node.

If I load the Form2 and scroll down a bit so the first node is no longer visible, and check the check box, then double click on a node it will expand, and make the top node visible.

My work around is to remove each node individually, i.e.
If I load the Form2 and scroll down a bit so the first node is no longer visible, then double click on a node it will expand.

Public Class Form2

Inherits System.Windows.Forms.Form

'Form overrides dispose to clean up the component list.

<System.Diagnostics.DebuggerNonUserCode()> _

Protected Overrides Sub Dispose(ByVal disposing As Boolean)

Try

If disposing AndAlso components IsNot Nothing Then

components.Dispose()

End If

Finally

MyBase.Dispose(disposing)

End Try

End Sub

and another one developed using Telerik 2011 Q2
(For Example: we have totally 10 forms. 7 forms were designed in Telerik2011 Q3 and 3 were designed in Telerik2011 Q2
we like to open forms developed in Telerik2011 Q3 in a system having telerik 2011 Q2 )
if we do so. Its getting error. (please refer attached image file to see the error page)
I mean its getting error while merging Telerik 2011 Q3 with Telerik 2011 Q2

I request Telerik Support team to give a solution as quick as possible.

Note: I have attached the Err.Page screen shot.

Please reply as soon as possible.
Regards,

GridHeaderCellElement in C++

I am using C++/CLI with the Telerik GridView. I have a checkbox column which I wanted to add the CheckBoxHeaderCell class to. (Reference: http://www.telerik.com/support/kb/winforms/gridview/add-check-uncheck-all-check-box-in-the-header-cell.aspx). I wrote the example and compiled it in C++/CLI from the given C# code. However, I do not know how to tell my grid view to USE this class as a columns header cell. Any help would be appreciated!

DataTypeConverter on ComboBox column

Hi,

I have added a TypeConverter to my ComboBox column which converts from string to Value which will allow me to paste either the Int Value or the String Value into the Combobox. This is all working fine.

What I would like to know is it possible to copy out the string Value using this, Or would I have to use an other method to do this.

In thought if I used ComboboxCell.Value.ToString() then it would convert the value to the String Version but it doesnt.

Thanks

Client Side get Button ID

Is there any way to get a buttons ID instead of just the Text.

I have a button Add under a "Pages" group and an Add under a "Users" group. Just getting the text isn't good enough.

Is there a similar method to: button.get_text() such as button.get_id() ???

Only code I could find in the help file was:
var button = args.get_button();
alert (button.get_text())

Thanks for the help. If there isn't then would be good to add to the future feature list.

Thanks!

Scroll to row without selection

In my case I want to scroll to the top row in certain circumstances. The code that works isn't elegant as it will fire events that I really don't want. To get around that I use a flag that I set before updating the grid, then reset after. Here's the code:

_fillingSearchGrid = true;
SearchResultsGrid.DataSource = results;
if (SearchResultsGrid.Rows.Count > 0)
{
SearchResultsGrid.CurrentRow = SearchResultsGrid.ChildRows[0];
SearchResultsGrid.CurrentRow = null;
}
_fillingSearchGrid = false;

Is there a better way to do this?
