Hi,
I have a problem when in my application I load a different layout from the default one:
If I have a project opened, his toolwindow is correctly docked under the ribbonbar and also the other toolwindows with the editing tools.
If I load a different layout for the toolwindows with the editing and the main toolwindow with the project is opened, the main toolwindow is automatically hidden.
I tried to force the main toolwindow to stay docked after the layout changes, but the only dock state allowed after the change is a floating toolwindow.
Is there a way to force the main toolwindow to stay docked after the layout change?

Thank you in advance.

Telerik.Wincontrol.UI.RadForm with Desert Theme

Everytime I create a Form with the Telerik RadForm then assign the Desert theme to it, it looks partly loaded only when I launch the application (As per screenshot).
If you look at the borders, they look blacked out.
I use Telerik Winforms 2011.1.11.419
It only seems to happen with Desert theme, and on all forms (even with no code in it).

Grid combobox value changing

Hi All,

I have a grid, which contains some combobox column.

Is there a way to catch the moment, when the user selected a new item from the dropdown list of a combobox column, but does not leave the column? (e.g.: similar to the SelectedIndexChanged event of the raddropdownlist control).

Best regards,

Peter

cell and row validation - urgent

We have a gridview and are having a problem validating cells. Problem is this: the first cell is valid, but the second is not valid. When the user changes the current row and then clicks away with their mouse, the focus returns to the first cell, but I want it to go to the second cell, so that the user can enter a correct value. How can I make the focus go to the invalid cell, not to the cell the user mouse-clicked out of?

Thank you.

TitleBar & MessageBox Frame missing

Hello Telerik Team,

Today we found the following two issues when working on our Application.

Issue# 1: Message Box frame missing ( Refer MsgBox_BorderNotSeen.JPG).
The frame (border, window) of the MessageBox is not seen but the Text on the MessageBox could be seen.
Issue# 2: Title Bar missing. (Already posted by Michael in Forums. Link: http://www.telerik.com/community/forums/winforms/forms-and-dialogs/title-bar-not-displaying.aspx).

Please let us know the solutions for the above two issues.

Thanks & Regards,

Expand / Collapse SelfReference Hierarchy

Hi All,

I want to expand / collapse all rows on button click event. I tried the dgv.MasterTemplate.ExpandAll()
and dgv.MasterTemplate.CollapseAll() functions but none of them work.

I have around 8000 rows and 6 levels. How do I do that?

Also I noticed, I expanded one group that has more than 2000 rows will take some seconds to expand and then I expand another one which has only 2 rows that also take same time of previous group. If I collapse previous group and then expand the second one it expanded quickly. Is this normal behavior?

Thanks in advance

Telerik.WinControls.UI.INI - What is this

Hi Guys,

I wonder if any one could help. We have a VB.Net Windows application that is using the Telerik WinControls (2009 Q2) suite and one of our clients has reported an event in the Windows Event Log with the following details.

--------------------------------------------------------------------------------
Event:
Class: File System
Operation: QueryDirectory
Result: NO SUCH FILE
Path: C:\Program Files\[Application Folder Name]\Telerik.winControls.UI.INI
Date: 29/Jun/11
-----
Filter: Telerik.WinControls.UI.INI
--------------------------------------------------------------------------------

When the product is installed to a client machine we do not create a folder inside our application program folder called "Telerik.winControls.UI.INI" and certainly don't have any code that looks for that location or requires a floder of that name to be created..
I assume that there is code somewhere in the Telerik controls DLL that is looking for that location, but as it does not exist the error is recorded in the Event Log. Please can you confirm? Also can you confirm if this code is removed from a later version of the controls.

I have attached a screen shot of the event log entry.

Any help appreciated.

Best regards,
Duane.

Possible Bug? RadDropDownList and DataView

I am experiencing a strange behavior on the RadDropDownList when its datasource is a DataView. I created an empty project to eliminate other possible factors.

On initial load, I set the datasource to a global dataview object, as well as the ValueMember and DisplayMember. The dropdownlist is populated when clicking a single button. As expected, the data is shown correctly.

If the dataview is refreshed multiple times (button clicked again), the data is shown correctly. However, if the user drops down the listbox before refreshing the data, the text for the items in the dropdownlist changes to "System.Data.DataRowView".

I have tried resetting the datasource, displaymember, valuemember, and performing a rebind after refreshing the data. I still encounter the same issue.

Test code is below. To see the strange behavior, add "RadDropDownList1.ShowDropDown()" after refreshing the data. Or simply display the dropdownlist before clicking the button.

Possible bug???? This can't be by design. :-) This behavior does not occur with the MS dropdownlist control. I have the latest version (2011.1.11.419).

Imports System.Data.SqlClient

Public Class Form1

Private _dvNames_List As New DataView

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click

Dim sSQLConnection As String = "MYSQLCONNECTION"

Dim oConn As New SqlConnection(sSQLConnection)

Dim oCommand As New SqlCommand

Dim oDT As New DataTable

Dim oDA As SqlDataAdapter

Try

oConn.Open()

With oCommand

.Connection = oConn

.CommandTimeout = 15

.CommandType = CommandType.StoredProcedure

.CommandText = "cp_MyStoredProc"

End With

oDA = New SqlDataAdapter(oCommand)

oDA.Fill(oDT)

oDT.TableName = "SQLDATATABLE"

_dvNames_List.Table = oDT

Catch ex As Exception

Throw New Exception(ex.Message, ex)

End Try

End Sub

Private Sub Form1_Load(sender As Object, e As System.EventArgs) Handles Me.Load

RadDropDownList1.ValueMember = "nameid"

RadDropDownList1.DisplayMember = "name"

RadDropDownList1.DataSource = _dvNames_List

End Sub

End Class
