I have radgrid  and placing complete Radgrid  in edit mode.

I have save button in command template.

I need to update the rows when  save button is clicked.

Is there a way to know the list of changed rows on server side so I can issue the update command only to that particualr row. I do not want to issue command for all the rows irrespective  whether it is changed or not.

Thanks

Hi,

I am trying to get a column value of a selected row in the radgrid.
I am using "DataKeyValues" in my C# code to retrieve the value. But it always returns an empty string. When I debug I can see the key but the value for that is empty. 
Following is my code. Please let me know if I am missing something.

Thank you,
Lahiru

I have a .aspx/web form that uses the Rad Decorator.  I am using one of the Responsive frameworks on the page and have constructed a menu using ul/li that will morph into a combo box when the page width decreases past a certain point.  This is all working fine.

I would like to use the RadComboBox for the mobile-sized menu container but I cannot seem to control visibility of the RadComboBox during page size changes using the normal method of doing so from media queries -- see below.


When I try to use the styles, they appear to have no effect whatsoever on the RadComboBox.  I have tried telling the Rad Decorator to ignore SELECT controls to no avail.

Is there a way through the CSS that I can control the visibility of the RadComboBox when the RadDecorator is being used?

Thanks in advance!

We are looking to implement a responsive UI application which allows server-side events (i.e. data, sql, etc.) to be pushed to clients and have the UI refresh but not lose context. For example, we have a prototype working w/INotifyRefresh and a WPF app. However, we would like to explore the idea of doing a web app.

The new ASP.NET version has support for SignalR which allows for server events and data to be pushed to the client. Can we achieve this in ASP.NET or MVC w/out writing a massive amount of code? The application uses listviews w/checkboxes, the underlying data (ids & text) is changed, added or removed while leaving valid, existing checked state.

I have a RadGrid where I am auto generating columns because they can changed depending on the source. And I want to display only certain columns and in a specific order. Its easiest for me to store the columns to display in a comma delimited string. I created the code below to try to do this. However it fails because in the Page_Load method the grid.MasterTableView.Columns is always empty, even though I do a DataBind first. Any idea how I can get this to work?

Thanks,
Jason

for test , we download the trial version of telerik and face following problems 
It Dosnot have  any problem on local Dnn Portal,but it takes us the bellow error on main website
 " Error loading RadChart inage ..." .
we added the tag Shown on first load of radchart in Web.Config > httphandler Section .
and add folder radcontrols>chart wich contains file image.aspx.
Please Guid us as soon as posible.

One of our users alerted us to a problem in Chrome with the RAD grid control.  He has about 100 items and after the operation (insert/delete) completes, the grid doesn't redraw.  If you move the mouse over the rows, it will redraw around the cursor as you move it.   Once you scroll the screen, it redraws the pieces that go off screen.   See attached screenshots.

We were only able to reproduce the problem in Chrome.  It worked fine in IE and Firefox.  I was just wondering if anyone else has seen similar issues.  We had not seen such problems before and I wondered if it wasn't something broken in the last Chrome update.

Thanks!

I'm trying to change the tab text in javascript.  I thought it would be a simple task but I haven't had any success with anything I've tried.

The first thing I tried was tab.set_text("NewValue").  This set the text property in the tab client object but didn't update the text currently visible to users. 

I then tried to get the DOM element for the tab text to update it directly using tab.get_textElement() but that comes back as null.

Does anyone have any idea how to update the tab text so it's updated in the browser?
