Hi i use radgirid
with row select property in clientsettings as showen below

<ClientSettings EnableRowHoverStyle="true"> <Selecting EnableDragToSelectRows="false" AllowRowSelect="true"></Selecting>

 

 

</ClientSettings>
and i have a  gridselectcoloumn in grid
<telerik:GridClientSelectColumn UniqueName="Selection">  <HeaderStyle Width="22px"></HeaderStyle>  <ItemStyle HorizontalAlign="Center" Width="22px"></ItemStyle> </telerik:GridClientSelectColumn>

my problem  starts here ;
radgrid supports multirowselect if only Ctrl key pressed
if ctrl key is not pressed earlier selected row goes to unselected.
i want to select rows by click on it with the earlier selected row keeped.
(is there a configuration parameter for that on radgrid?)
how to accomplish this task?
tahnks

 

 

 

 

 

 

 

 

 

 

 

I've got a RadGrid that's filled dynamically with content... the single grid on the page is used for a variety of queries, so it never knows what columns are going to fill it beforehand.

I've enabled Grouping, and it works... I can drag a column to the header, and the data groups just fine.

However, when I click on the grouped column to try to return it back to the grid (so I can group by a different criteria), I get the following error:

Server Error in '/' Application.

Hi

I'm using RadFileExplorer to select multiple images, is there a way to preselect files either clientside or serverside?

/Thomas

Btw. thanks for these excellent tools :)

I have a combobox on a page that loads other comboboxes dynamically when the user selects a value.  After this happens once, the user can no longer make a selection in the original combobox.  I made a simple project to reproduce this behavior.  Any ideas as to what I can do to fix this? 

Edit: Telerik version 2009.3.1314.35. Can't upgrade because of project specs.  Thanks.

We're having display issues with the Web20 theme formdecorator for the asp.net login control. The issue shows up in the iPhone and iPad, but not on Safari when run in Windows. The right side of the Login and Cancel buttons are repeated. We haven't customized the built-in themes at all.

Here is the code for the formdecorator in the page:

Here is the code for the buttons in the login control:


I've attached a picture that shows the problem. (Ignore that the buttons themselves are repeated. This was for testing.) Look at the right sides of the buttons:

Im working with the RAD Scheduler control.  I've declared a RAD Scheduler control on my ASPX page, and it's OnAppointmentUpdate attribute is as follows:

OnAppointmentUpdate="RadScheduler1_AppointmentUpdate"

In the code-behind, the event handler is defined as follows:

protected void RadScheduler1_AppointmentUpdate(object sender, AppointmentUpdateEventArgs e)
{
    //CODE
}

Documentation says that by referencing e.ModifiedAppointment, I should be able to access the new Appointment values I've entered right before they're inserted into the database.

But -- These values are the same as the original Appointment object!  It appears as though any new values are not accessible via the e.ModifiedAppointment object.

Any ideas what's going on?  Seems easy, but I'm stumped!

TIA!
