After bind the radgrid to datasource to show the data with start /end date and  other fields in the grid. If the user input start and date on the date picker outside the grid, and click serch.  I like to filter the grid again use something like FilterExpression (?) instead of rebind the grid on server side, is it possible, how I can do that? where the code should put to?

Thanks.

Hi,

I would appreciate if you can tell me if there is a property for minimum file size similar to MaxFileSize. My requirement is to prevent the user from uploading an empty (0KB) file. Most of our users use Internet Explorer and whenever they try to attach a file (empty/0KB), progress bar doesn't move at all and gets stuck in a limbo. It seems to be working fine in Firefox though.

In order to go around this problem, we have decided not to allow the user to upload empty files (0KB). Is there such a property for RadAsyncUpload that prevents the user from doing so?

My html looks something like this:


If this property is not available, please advice other alternatives?

Irfan,

I do have the following scenario: I am having a Radgrid inside a visual Webpart which is using AJAX. The Radgrid with the Loadingpanel exists within the UserAdministrationUserControl, the RadAjaxmanager is added to the UserAdministrationWebpart.cs by following code:


So far it works quite well. However I have the scenario, the Edit-Button of the Radgrid opens a ModalDialogPopup for editing the selected User. When editing is finished and the ModalDialog is closed, the Radgrid should be reloaded/refreshed. This is possible by a javascript function, which is called after closing the modaldialog by a callback. And here is my problem.

The Callback-function should do just the following:


But of course that isn´t possible as the RadAjaxmanager doesn´t exist in the UserControl, where the Javascript and the other controls are.

I´ve tried giving the RadAjaxmanager an Id and finding it by:


But that doesn´t work, the Control cannot be found (in the console it returns the function as "$find('').ajaxRequest("Rebind") ).

While Debugging, I´ve found out, that the AjaxManager always gets the same ClientID, so the following is starting a refresh (i didn´t set the controls ID in that case):


However, I do not want to hardcode the Controls ClientID. Besides, altough it is updating the Radgrid in that case, the LoadingPanel does not show up by using that Javascript (it works without a harm in all other cases eg. paging). And therefore it is not very userfriendly.

Any Help and suggestions will be very appreciated

I'm trying to make a Cancel button for my RadEditor, but running into a problem.  On my site, I display the RadEditor as Enabled=false when the page loads.  The causes just the text to be seen, not all the editing controls and whatnot.

There is a "Add/Edit Text" button the user can click that will enable the RadEditor, and show my Submit and Cancel buttons.

When the user clicks my "Cancel" button, I'd like the RadEditor to once again be disabled AND discard any changes that were made.  I can disable it no problem, however the unsaved changes persist.

On the older RadEditor, when you clicked the native "Cancel" button, changes were discarded.  I'd like to replicate this using the new RadEditor.

Any suggestions?
