Set the format string through the designer

I need to format this "123456789" to this "12-3456789" in a column.
I know I can do this in the code, but is there a way to do this through the designer?
I tried setting the FormatString of the GridViewTextBoxColumn to {0:##-#######} but that doesn't seem to do anything.

Thanks!

[Browsable(false)] attribute

We've a custom object with several properties. When implementing the RadDataEntry control for visualizing details of each record displayed in GridView, we want to hide some properties. We implemented the [Browsable(false)] attribute and that hides the property in the RadDataEntry as expected, however it also impacts in the Grid. Is there a way to display a property in the Grid and hide it in the DataEntry?

Thanks!

DateTime Format Copy Select Value ALL DIFFERENT

I have a grid with a datetime column that gets populated.
I format the date yyyy-mm-dd 12 hr. (yyyy-MM-dd hh:mm:ss.fff tt). For example: 2016-05-12 02:38:25.613 PM

For Each column As GridViewColumn In GridView.Columns
If TypeOf column Is GridViewDateTimeColumn Then
'change the formatting
Dim col As GridViewDateTimeColumn = TryCast(column, GridViewDateTimeColumn)
col.FormatString = "{0: yyyy-MM-dd hh:mm:ss.fff tt}"

'set the tooltip on the column

End If
Next

Now, when i select the value, the actual value is not my formatted, but instead: mm/dd/yyyy. For example: 5/12/2016 2:38:25 PM
If I copy the cell and paste in notepad it shows yyyy-mm-dd 24 hr with only hr/minute, no seconds. For example: 2016-05-12 14:38

Can anyone explain this RETARDATION??

Sorry to sound like a jerk, but it is quite frustrating when simple things like this are not correct. This control has been out for 8-10 years now. Why would it not ALL match the SAME value that is displayed?? IMAGINE THAT!

It is also irritating to have to spend time finding and bringing this up and expected to pay support thousands each year for things that are correct and function normal by now. No excuse for this.

...I have a feeling I will not be getting a response, like my MANY other threads that go unanswered here.

Please build better controls that work as intended and not need constant workarounds as well as have lingering issues (performance) that never seem to get resolved.

BestFit method not working as expected

Hi,

I'm trying to use the BestFit method dynamically to resize the column width property as the largest word in my DataSet in one column specific. But when I use this method, the application fit the column as the largest word that I can see, and if I slide the scroll down, some words in the grid column is truncated.

How can I do to display all my grid data with no truncate words?

Regards

Error importing RTF

Hello, I am not sure whether to post this in the RichTextEditor forum or the Telerik Document Processing forum as this problem exists in both import/export methods.

This is the code that triggers the error:

using Telerik.WinForms.Documents.FormatProviders.Rtf;

namespace ConsoleApplication1

{

class Program

{

static void Main(string[] args)

{

I am pretty sure that this RTF is well-formatted; it opens correctly in Microsoft Word, and it came directly from an export of a Telerik Report.

Is there anything I can do to fix this?

Chartview Scatter Sampling or Virtualization

Does the Winform Chartview have built in Virtualization or Sampling? We are experiencing slow response time with large clusters of points! How would you handle this scenario?

Thanks
