Hello Telerik Team,

I Have an issue regarding the filter of the grid on readOnly columns.

When the user goes between the filter cells with the Tab key or the Arrow keys the curser skips the readOnly columns.

How can this behavior be fixed?

                                                               

Regards,

Namma.

Is there a way to programmatically set the focus to the first cell in a child add new row? 

Hi,

Is it possible to reset the dock settings as set in the vs designer, in case the user messed up the lay-out?
In an MDI scenario, I would like to reset the open childforms. Currently dock settings are stored in the registery (as xml)
Removing the setting does open the form in 'factory settings' (vs designer lay-out) when the form is re-opened, but I'de like to visually reset the form without losing it's current bound data...

Or is the only solution to close the mdi-child I'de like to reset?

Kind regards,
Alex

We recently changed all of our DateTime fields to DateTimeOffset. Now when we display one of the dates in a GridView, we get:

{"Converter can't convert"}

Is there something else we have to do to support DateTimeOffset in the grid?

Here is the detailed exception:

System.FormatException was unhandled
  Message=Converter can't convert

Hello,
I have a grid with a GridViewTextBoxColumn.  When this cell goes into edit mode, I would like to have a button that the user can click to launch a modal dialog form.  On this form the user can edit the data of selected cell like on the Teleriks Expression Editor form.

Any help is greatly appreciated.

Thanks,
Sz

Hey at Telerik

I have found a bug in the RadDateTimePicker.
When the control is continuously enabled/disabled the Text element of the control stops showing the date.

I need this functionality to rebind a RadDateTimePicker to a SelectionChanged event on a RadGrid.

I have reproduced the bug in a little test project (Of cource without references). http://kort2.lifa.dk/examples/RadDateTimePickerMissingDateText.rar

Try and disable/enable the RadDateTimePicker numerous times, after fourth click the Text control element of the RadDateTimePicker stops working.

Sincerly Jan.

hello,
i have a DropDwonColumn in my Grid i want to bind a specific cell in that column not all cells in the column.
is that possible?

Hi there

Hi

Sometimes the following exception is thrown in our application:

Parameter is invalid.

No line of code is specified in this exception. One of our customer is using Citrix and this exception is more frequent there.

How can I solve this problem?

The exception is oftenly thrown while refreshing data in RadGridView, RadDatagridviewComboboxes and other controls. Actually I can not reproduce this exception on my machine but in the situation told by customer, we are refreshing data.

Telerik version used by application is v2011.1.11.419.

Any help would be appreciated.

Thanks

Regards

 

hi everybody is there a way that we could loop to selected rows using two buttons button1 and button2, like for example i want the small arrow to point to the first selected row with document name f10_oct1_en.pdf, currently it is pointing to f36_may07_en.pdf, and each time i click the button it jumps to the next selected row which in my case if the arrow is on f10_oct1_en.pdf will go to f21_dec17_en.pdf, same thing will happen to the prev button only going backwards..
i have attached a png file on the thread so you could understand what i mean...
thank you very much...
