I have the following structure:
- Main page
-- user control
--- tabstrip
---- tab (pageview)
----- user control
------ grid

The user was concerned that as they moved around the app that the grid would maintain its data. I do build a datasource and save it to state, and then on postback refresh from state in order to respond to the current request.
But if the user clicks on the tabstrip, I clear all state data, then use Response.Redirect to go back to the Main page. This forces Page_Init and all other load and render events which regenerate the grid.

What's weird is that the structure of the grid resets but not the data. I'm clearing filters, resetting sorting, resetting grouping, and yes, the DataSource is null. I am not rebinding in this event, because the grid data source is already null. If I do rebind, the larger cycle is re-initiated, so I'd rather avoid that. I can set a flag that detects a reset and initate the rebind from Page_Init or Page_Load.

I'm just wondering why the grid structure is refreshed but not the data. Do I need to set the RadAjaxManager to trigger/update some component other than the grid?

And if a change to the AjaxManager is required, what would that be given the above structure? Aside from making the nested components aware of parent components through properties, I'm not aware of how I would set the AjaxManager to update based on an event outside of the local scope.

I understand the request could be vague with no further info, and will do what I can to provide relevant info on request.

Thanks!

I need some assistance as to how can I assign the DataValueField Value using the code below.

Thanks as always.

I am using RadAsyncUpload in a form which work fine under HTTP. As soon as I turn SSL on and access page through HTTPS, when I click select button

•  it doesn't work (open dialog to choose file) on IE 7 and 9, but works fine on firefox.
• on firefox dialog open and after selecing a file it start uploading file then in give red light with error in firebug (uncaught exception: Error while uploading, HTTP Error code is: 0)
• if on IE I disabled silverlight Add-on,I can open popup to choose a file, but progress bar keep loading and never complete uploading file or gives error

 
I have tried all below but still same issue

1.  Telerik.Web.UI.RadAsyncUpload.Modules.Silverlight.isAvailable = function() { return false; };, 
2. setting EnableFileInputSkinning = false
3. checking .axd is correctly configured in webconfig.

Also, if i set DisablePlugins="true", the dialog appears but file fails to load correctly and give red light.

What's the best way to notify the user that they've arrived at the maximum length supported by a particular field?  Will i have to use a key up function and test the length, or is there some alternate method i might use?  It doesn't appear that there is anything built in - is there something i missed?

Hi,
Is it possible to disable or hide sorting items of RadGrid header context menu for specific columns? In the other word, sorting config some of columns set to false, and I want to hide this items in header context menu.  

I need to get the value of the selected index or row id and pass it to a base page.

Is there someone who has done this?

Is there a way to show the month view, but instead of having the first line be the first line of the month, set a different week to be the first week in tihe month view?

For example, if the user selected the date Sept 22nd (or if we auto set it by defaulting to the current date), then the week of Sept 19th would be the first week in the month view, and it would show the next 5 weeks in the month view (spanning into October).

Is this possible?

Hi all,
I am getting JScript error as "Microsoft JScript runtime error: 'Telerik' is undefined" while running my project.
I have just tried configuring the project  from the menu bar 'Telerik->Rad controls for asp.net ajax->configure project' and it gives me this error.
Please find below my webconfig file.I could find some threads in forum about trouble shooting for the same.But that didn't solve my issue.
I am using .net 4.0 version.Please help me on this.

Greetings.

I have a 100% code generated RadGrid.  It's purpose in life is to interrogate and render UI to support a Code-First Entity Framework model.

During entity edits/inserts, I would like to display a RadComboBox with checkboxes (multiselect) for child entities.  For example:

Editing Company X
ComboBox shows 20 potential employees (entire universe of the Employee entity)
Employees can be selected, and the child relationship between Company -> Employee (1 to many) are updated during RadGrid save.

Getting the combobox to appear and populate itself with the list of potential choices is no problem. I'm running into trouble when saving.  I'm trying to use the same approach that I use for other custom templates associated with the grid....



This fails for a couple reasons.  1) If I select more than one checkbox, I run into an issue trying to add the same key twice.  2) More importantly, even if I only select one item, the RadGrid update process doesn't like what I'm trying to do here (complains that a property named Employee was not found in Company).  This makes sense since Employee is a related collection, and obviously I need to be doing things differently in ExtractValues (or somewhere else).... I'm just not sure what/where.

Thanks!
Mike
