I have a problem with RadGridView on Winform C# that is couldn't change any properties of RadGridView such as IsCurrent, IsSelected, CurrentRow, ... It's not effect yet.

For example:

My grid isn't readonly, and I changed some values below:

... then the value of CurrentRow when I watch is still null.

... then it's still show as false for that.

I wanted to show a clear button to either clear the value or text of the control.

The idea is the same as the clear button in 

dateTimePicker.DateTimePickerElement.Calendar.ClearButton

But I don't see any ClearButton from its child elements.

I came up with the idea to rename the Close Button in

radTimePicker.TimePickerElement.PopupContentElement.FooterPanel.ButtonElement

and to add a clear action on its Click Event.

I came up with this code:

radTimePicker.TimePickerElement.PopupContentElement.FooterPanel.ButtonElement.Text = "Clear";
(radTimePicker.TimePickerElement.PopupContentElement.FooterPanel.Children[0] as RadButtonElement).TextElement.Text = "Clear";
(radTimePicker.TimePickerElement.PopupContentElement.FooterPanel.Children[0] as RadButtonElement).ToolTipText = "Clear";
radTimePicker.TimePickerElement.PopupContentElement.FooterPanel.ButtonElement.Click +=
 delegate(object sender, EventArgs e) {  radTimePicker.Value = null;  };​

The tooltiptext works as well as the clearing of value. with this, I know that I am using the right button element.

But the Text always revert/return to "Close". 

Am I forgetting something?

Hey!

How to align the values in the pivot grid cells?
The text seems to be centered by default but i found no obvious property to change this behaviour. I need right alignment.

In the Silverlight version of this control they seem to be aligned to the right by default.

Cheers,

I have a column group that contains 5 rows. I wish to hide the headers of the last 4 rows. I did put in the following code in the viewcellformatting event (below, but it did not hide the column group rows. My headertext on those rows are empty, and the images are attached. "Capture2.jpg" is the image before using the viewcellformatting event code. "Before.jpg" is the event code below being implemented, and "result.png" is what I am attempting to achieve. Thanks in advance for any help.

    Private Sub RadGridView1_ViewCellFormatting(sender As Object, e As CellFormattingEventArgs) Handles RadGridView1.ViewCellFormatting

        If TypeOf sender Is GridHeaderCellElement Then
            e.CellElement.Visibility = Telerik.WinControls.ElementVisibility.Collapsed
            e.CellElement.AutoSize = False
            e.CellElement.MaxSize = New Size(0, 0)
           e.CellElement.MinSize = New Size(0, 0)
           e.CellElement.Size = New Size(0, 0)

       End If​

I'm not databinding, just trying to set the timepicker to null. I can set the nulltext property, but how to set the value to null?

Later
