I'm using a RadGrid, and I'm able to show and hide columns using client-side script:

 

mygrid.get_masterTableView().hideColumn(i);

But, when I hide the column, it leaves a blank space where the column was located. Is it possible to have the remaining columns automatically resize and fill the empty space?

If this isn't possible, can I manually resize the remaining columns? I've tried the following script to set the hidden column width to zero, but it doesn't have any affect:

mygrid.get_masterTableView().resizeColumn(i, 0);

Is there a way to send tokens such as OAuth2 with the call to the ODataService?

I can see that there may be a way of injecting headers in the client-side event

OnRequesting but only if these are exposed in the args.set_Options object.



Thanks

I have a radgrid placed on a web form that uses PeterBlum's RequiredValidator and CustomValidator to validate some data on the page. 
I would like to validate the web form data before performing an Insert or Update on the grid.   
I am using radgrid's automatic insert and update actions.

The following approach succeeds in preventing the insert form from loading if the validation fails, but doesn't continue on to displaying the validation messages.
Any suggestions?

Hi
I have a reset button on a form with the following client-side code to clear the grid:



This works great but the NoMasterRecordsText is not shown on reset. This is set as follows in the MasterTable view:


Perhaps somebody could shed some light on how to achieve this

Are there any plans to make the rotator touch enabled?  

All of my customers expect touch enabled components, especially for this type of control.

Thanks, Marty

Hi - i have a requirement very similar to what is achieved in http://demos.telerik.com/aspnet-ajax/listview/examples/itemdragdrop/defaultcs.aspx.

However, the main difference in my case is that the control to which i would drop my items (equivalent of Genre list shown in the right in the above link) is located in the master page and my list view is located in the content page.

When i drag the listview item onto the masterpage control, the destination is null. I used  in event to get the destination item. If i drag the listview item onto any other control in the same page, the destination gets the proper value.

Is there a work-around to this problem. Am i missing something here?

Thanks.

Hi,
I've recently upgraded my application to telerik version 4.0 and noticed that the style of my application combobox automatically changed.
I'm using "Vista" skin and apparently they've changed it in the core so now it's different

OLD VERSION Style


NEW VERSION Style


Is the old skin still available or is it anyway to apply the same settings manually?

Thank you in advance,

Marcelo

Is it possible to load an Xml file into a RadGrid for web display purposes. I tried loading an xml file into a DataSet and assigning that to a RadGrid's DataSource but it only displays one level.

I will not know what the content of the xml files will be so can't specifically add fields to the grid ect.

Is this possible?

Good day!

Is there any way that the scroll position be synced between schedulers? The application I'm creating has multiple schedulers, side-by-side, but I only want to show the hours column for the first one to save space, but the height of the scheduler exceeds the browser window, so a scroll bar is shown for each. Each scheduler is in a RadPane.

Thanks.

Afternoon,

The problem I am having is that I have  a hierarchical radgrid inside of an updatepanel, with the grid set to HierarchyLoadMode="ServerBind".  When I have the grid start out with expanded rows, images that are loaded into the grid are inserted properly as follows:

The grid puts "true" or "false" into the cells, and then in ItemDataBound those values are removed for a checkmark or an x (for true or false, respectively).  When the page posts back, some of the grids update to show images, other do not.

The reason that I am doing HierarchyLoadMode=ServerBind is because I need to get a total count of the items that will be in the grid, and I get that count by going across the items in the grid and for each that is a chlid item I increment a count.  If there is a handier way to do that, I would also be amenable to switching HierarchyLoadMode to ServerOnDemand or something.  I need a count of the items in the grid and it has to be correct regardless of the expand/collapsed state of the items.  When I had ServerOnDemand and the rows started collapsed (a requirement), the count of the child items came to 0 each time, even if there were items in the grid.  I currently get the count of the items in the Page_PreRender event, when all the grid bindings have been completed.

Any ideas?  Can I count the items in the grid in some other way than going across rows in Page_PreRender? If not, is there a way I can set the AJAX to load images in upon expansion of the rows, as is currently not happening?

Thanks very much,

Kaleb

EDIT:  The update panel has UseChildrenAsTriggers="true" and UpdateMode="always"
