CellBeginEdit

Hi,

Ive created a grid, one of my columns in the grid is a GridViewLookupColumn. Ive subscribed to the CellBeginEdit event because I want to prevent users from editing certain cells. When the condition is met in the event handler I set e.Cancel to true so that the editor is not displayed. All works fine until the form is closed (disposed), I then get the following exception (stack trace), can somebody help please?

Render don't change after value set with custom format

Hi,

I have a problem with the most simplest thing with RadDateTimePicker (2009.3.9.1203). I only want to set date, at form opening, like this :

Me.radDateTimePickerStart.Value = DateTime.Now.AddDays(-7)

Me.radDateTimePickerEnd.Value = DateTime.Now

if I set property of format to System.Windows.Forms.DateTimePickerFormat.Custom, the render is not updating on the form, but if i debug the control, the value is ok. With custom format the problem disappear.

Here is the complete control setup :
Me.radDateTimePickerStart.AutoSize = True

Me.radDateTimePickerStart.Culture = New System.Globalization.CultureInfo("fr-CA")

Me.radDateTimePickerStart.Format = System.Windows.Forms.DateTimePickerFormat.Custom

Me.radDateTimePickerStart.Location = New System.Drawing.Point(782, 531)

Me.radDateTimePickerStart.MaxDate = New Date(9998, 12, 31, 0, 0, 0, 0)

Me.radDateTimePickerStart.MinDate = New Date(1900, 1, 1, 0, 0, 0, 0)

Me.radDateTimePickerStart.Name = "radDateTimePickerStart"

Me.radDateTimePickerStart.NullDate = New Date(1900, 1, 1, 0, 0, 0, 0)

Me.radDateTimePickerStart.Size = New System.Drawing.Size(150, 22)

Me.radDateTimePickerStart.TabIndex = 5

Me.radDateTimePickerStart.Text = "RadDateTimePicker1"

Me.radDateTimePickerStart.Value = New Date(2010, 2, 12, 14, 18, 35, 101)

thx,

Excelexport with Gridlookupcolumns

If I have a gridview and want to export it to excel it does export all values correct.
But if I have a column that is a lookup I get the ID and not the displayed value of the lookuptable value.
Where do I set that settings for my export?

My exportfunction from your VB examples

                            If file.Extension.Equals(".xls") Then 
        
                                'Här skall det bli ändring till gamla Excel

Contents of PanelBar in ExplorerBarStyle don't resize properly

Hi,

The contents of the panelBar in ExplorerBarStyle do not resize, if a scrollbar is visible. The vertical scrollbar stays at the current location until one of the contained groups is collapsed or expanded.

Steps to reproduce the problem:

1. Create a new form and add a Panelbar with DockStyle.Fill and set the GroupStyle to ExplorerBarStyle
2. Add a few groups to the Panelbar and set the EnableHostControlMode to true
3. Make sure the CanScroll Property of the Panelbar ist set to true
4. Start the Application
5. Resize the window so that the vertical scrollbar is displayed
6. Drag the right border of the window and resize it (now the scrollbars should be at the location they were before the resizing)
7. Click one of the groups to place the scrollbars in the correct location

Is this behaviour a bug or am I missing something really simple? What do I have to do to always place the Scrollbars at the right border of the window?

My System:

OS: Windows 7 64bit
Framework: Version 2 0

Edit: Sorry, wrong forum. I've posted it in the Panelbar forum.

RadCheckBoxElement does not show difference when tristate and set to ToggleState.Indeterminate

Hello Telerik team.

NOTE: this issue appies to RadCheckBox (and derived/related) in general.

I've noticed that when using a RadCheckBox in either a winform or a as RadCheckBoxkElement (as custom cell edit control in a grid cell) it shows a checkmark when it is set the value Indeterminate.

This occurs as well as for invokation by the user as well as programatically.

MS's checkbox has a nice square to indicate that the value of the checkbox is indeterminate. So Telerik showing a checkmark for both checked and indeterminate is quite confusing to a user.

On a usercontrol / winform the workaround is simple: Just use the MS checkbox instead.
However, as a RadCheckBoxElement in a gridview, there is no workaround for this....??????:

Please let me know how I can use the RadCheckBoxElement in the radgridview cell and see the differnce between Checked, Unchecked and Indeterminate visually.

Kind regards,

Jack
