Set CurrentFilterFunction to NoFilter when user deletes filter value

I need to be able to set the CurrentFilterFunction to NoFilter when the user deletes the value without manually selecting the NoFilter option from the menu. The following code is useless since the CurrentFilterValue contains the value that was deleted.

foreach (GridColumn column in RadGrid1.MasterTableView.Columns)

{

if (column.CurrentFilterFunction != GridKnownFunction.NoFilter

&& string.IsNullOrEmpty(column.CurrentFilterValue))

{

column.CurrentFilterFunction = GridKnownFunction.NoFilter;

}

Here is the description from the tester: If you enter a value in a filter field and highlight thevalue and hit the delete key then enter a value in a different filter and selectthe filter icon… the first value you entered and deleted re-appears and isincluded in the filter.

RadCalendar IsSelected ignored

Hi,

It seems that the RadCalendar.IsSelected property is ignored. The below code should randomly select 1 of every 5 days. Instead none are selected. Any help is appreciated.

[Solved] Disable sorting / paging / filtering programmatically

Hi!
I'm trying to disable sorting / paging / filtering on my grid according some condition on the page.

The code is the following

            grid.AllowPaging = false;
            grid.AllowSorting = false;
            grid.AllowFilteringByColumn = false;

This code doesn't work as expected. If I disable everything, the rendered grid has everything enabled and it's disabled ON NEXT postback. So It works, but with delay. The same if I try to enable everything again.

I placed that code on different events on the page / grid life cycle with no luck. Same behavior. I want to disable those commands and immediately see them disabled, not on next postback.

Thanks!

RadGrid Automatic Paging Hangs with Ajax

Hello!

When I have a radgrid nested inside of an RadAjaxPanel or associated with a RadAjaxManager, automatic paging will not work. If the ajax panel or ajax manager is removed, the grid will postback to the next page. Within the panel or associated with the manager, it never postbacks to the next page and appears to hang. Any suggestions?

Thank you for any feedback that is provided!

switching to day view throws javascript error

Hi

Switching to day view throws the following error.

j is null

_onAppointmentMouseOver()Teleri...d16cbdc (line 8611)

_onDomEvent()Teleri...d16cbdc (line 7120)

createCallback()Teleri...d16cbdc (line 6)

var n=(j.get_allowDelete()!=null)?j.get_allowDelete():this.get_allowDelete();

Also, I have noticed appointment object becomes null when switching to day view.

Any ideas what could be the cause of this?

Thanks

but it did not work.

How can I do it?

RadAJAXManagerProxy Problem

Below is the scenario that I am not able to solve.
1. Master/Content Page setup.
2. Content Page has the RadAjaxManager object and a web user control (lets call it ucMaster)
3. ucMaster contains 3 other user controls, uc1, uc2 and uc3. uc2 and uc3 are displayed based on a selection in ucMaster. Both are loaded but the .Visible property is used to hide one or the other control.
4. uc1 has the RadAjaxManagerProxy1 and uses a radWindow dialog to get values and update the panel via ajaxrequest. (Works fine)
5. uc3 has the RadAjaxManagerProxy2, and uses a radWindow dialog to get values and update the panel via ajaxrequest. The "UpdatedControls" section uses the radAjaxManagerProxy2 as the "AjaxControlID" so that the panel is updated when the radWindow dialog is closed. (Does Not Work).

If I include the AJAX Setting in the ascx page under the RadAjaxManagerProxy AjaxSettings section, I get an error when the RadAjaxManagerProxy1 invokes an update for user control uc1. The error is: "Sys.InvalidOperationException: Could not find UpdatePanel with ID 'ctl00xxxxx_grvContactsPanel'. If it is being updated dynamically then it must be inside another UpdatePanel."

If uc3 is visible, the error does not come up.

I removed the "UpdatedControls" section from the radAjaxManagerProxy2.AjaxSetting section and add the control on the server-side in the page "PreRender" event. The code runs, but the panel does not get updated. If I move the server-side code to the "ajaxRequest" event handler I get the same error as before.

Any help with this will be greatly appreciated!

Thank you.

       I am using the telerik controls extensively.

      I am using the RadListBox control and it's 'AllowReorder' property to move the items of RadListBox up and down.
      Now, i want that items of two listboxes can move Up using single UP button and Signle down button for two Radlistboxes.
      Can i do that.

     In addition to that i need to edit the item (option) of one of my RadListBoxes on doubleclick on that item, can i do that ?
