Hi, 

i am having RadGridView, where i have "GridViewHyperlinkColumn", i need to remove Hyperlink based on some conditions, how to do that.

Note:- i don't want to make visible as false, just need to remove link alone.

hi....

in  my text box i have to enter only integer values.
so what mask i have to give its properties?

I have a multi threaded single form WinForms application using mostly(all) Telerik controls. Recently i have experienced a problem that seems to be at random. Sometimes, when giving focus to the application it throws a NullReferenceException and causes the application to shutdown.

I captured the detail from the exception this time which has been pasted below. I found another post that may be related.

http://www.telerik.com/community/forums/winforms/general-discussions/net-runtime-2-0-error.aspx 

I have not always had this problem as it just appeared in the past few days. Some of the recent changes i have made that may or may not be related:

Recently upgraded to the latest controls package.
Added additional RadButtons
Added columns to an existing RadGridView's (I found another error here but wasn't able reproduce after i corrected it where my control was not being recognized at runtime.)

Also, although my application has multiple threads the error seems to be related to me giving the application focus or clicking on a button(or attempting to) and it doesn't seems to be related to any specific button, other thread changes\events.

Is anyone else experiencing this or know a solution? 

Thanks!

I like to have the caret shown when the RichTextBox gets the focus, i.e., when tabbing into it. I use the following approach.

Private Sub RadRichTextBox_GotFocus(sender As Object, e As System.EventArgs) Handles RadRichTextBox.GotFocus

    Me.RadRichTextBox.Document.Insert("", RadRichTextBox.CurrentEditingStyle)

End Sub

While the caret size is smaller than usual it achieves my goal.

My font little special. It's little bit upper.So when I use my font , the form icon image and form text Not align. the font Font than the picture.
and for fixed it , I use visual Style builder. RadForm--->RadFormElement--->but there is not have any option Individually modified the label padding of form. I think if can, I change the title text label padding: 0,0,0,-5 . and let the label and icon Align. so can u help me ? or give me a solution?

I'm use Visual Style Builder change the RadButton--->RadButtonElement--->TextPrimitive---> Margin:0,0,0,-6

and use in vs, like this:

If I set the gridview columnheader.text alignment to middle right when using ExcelType filtering, it overlays the filter button image.  How can I avoid this?

In my app a use can load a text file in a radTextbox (logs, etc.)  I want to print/preview the contents but get this error;

    "Unable to cast object of type 'Telerik.WinControls.UI.RadTextBox' to type 'Telerik.WinControls.UI.IPrintable'."

I presume the RadPrintDocument cannot handle this type of control.  Is there anyway to do this or any other rad control I could use to load the contents of a text file that would work with the RadPrintDocument/print preview feature

Hi guys!

I have RadListControl with Countries list, that contains images(countryflags) and Custom country name as HTML text, to understand what I mean, check the attached screenshot please!

So what I want to do is:

When I press key I want radlistcontrol to scroll to necessary country

Example: when I press key "G" I want to scroll to "Germany" and so on...

Is it possible to do this??

Thanks very much for the answer!

Hi Guys

I have a RadGridView with only one editable column
The editable column is a GridViewDecimalColumn.  I have set the FormatString property to be "{0:P}" and it successfully appears as a Percentage.  However when I set the DataEditFormatString to be"{0:P}", it does not appear as a Percentage when editing.

How is the DataEditFormatString meant to work as I cannot find much information about what it is meant to do or how to use it?

Thanks
