I have a RadTabStrip that has to perform some server-side processing where a file streamed into a database and uploaded. I have this working successfully.

When this processing completes I need to set focus on a different tab in the PageMultiPage and that new tab needs to requery the database and refresh its dislayed contents ... in essence a postback to query the database and display current values in a RadGrid.

Is there a way to trigger this navigation and postback on the the new tab? Is there a way to cause a postback when the user changes tabs?

If so, please list code example on how to do this.

Thanks.

WindowManager Exception

Hi

I am trying to call a RadWindow Alert from a RadGrid ItemCommand but get this exception

"Sys.WebForms.PageRequestManagerServerErrorException: Object reference not set to an instance of an object."

I am trying to test for some selected items within a sub-grid, so my code is:

public static void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)

{

RadGrid RadGrid1 = (RadGrid)sender;

if (e.CommandName == "AddToCart")

{

if (RadGrid1.SelectedIndexes.Count == 0)

{

RadWindowManager1.RadAlert("No documents have been selected", 250, 100, "Add to Document Cart", "");

return;

}

GridCommandItem Item = (GridCommandItem)e.Item;

ImageButton btnAddToCart = (ImageButton)e.Item.FindControl("btnAddSelectedToCart");

....

..... rest of code...

}

This errors on the RadAlert line...
Any clues please.

[Solved] acces a field in a web user control

Hi,

I'm presently working on a application that use a radGrid with a Web User Control, so I used this demo to help me. I also want, in my Web User Control, to have a button that will make appears a window that will return a value that will fill a field (tbField) inside the Web User Control (like in this demo). So I tried it out, but I wasn't able to realise my scenario. Here is the problem : the javaScript code for calling the window and get back the value is write in the page that containt the radGrid. I'm able to get the value from the window, but I don't know how to set it to the field in the Web User Control (tbField). Here is my code in js function :

// Function that is called from the window to "get back" the value and fill the field tbField

function test(args) {

RadAjaxManager1.ajaxRequest(args);

}

So, how do I access the field in the Web User Control from code-behind. Guess it should be something like

"row that is edited".FindControl("tbField") as TextBox

but I don't know how to get the edited row.

Databinding a control in the ItemTemplate

I have a RadPanelBar bound to a datasource. In the ItemTemplate I have checkboxlist bound to another datasource. The select parameter for the datasource for the checkboxlist is the RadPanelItem's value.

This is probably very straight forward and would appreciate some help in accomplishing this.

Thanks

radWindow title bar has strange transparency issue

I have been trying to get rid of the strange section under the titlebar without any luck. Please see my attachment. Someone did post a similar issue and the solution was within the css. The following was the link I followed.

http://www.telerik.com/community/forums/aspnet-ajax/window/radwindow-with-transparent-title-bar.aspx

I didn't know exactly what was used for the gif file ( probably just a solid thick line). I added the css lines (with the exception of the section that he was told to eliminate), but I still have that strange line there. Could anyone offer any suggestions on how to get rid of this? If the gif file is needed, could you tell me what the gif should look like.

Thanks,
Amy

IE6: RadWindow in screen are missing the window top bar with the close/maximize buttons.

RadWindow in screen are missing the window top bar with the close/maximize buttons.
The buttons are there as we can click by guessing their location - they are simply rendered as invisible

This occurs intermittently (on the same page) only for IE6 users. We have tried removing any custom CSS, and getting spaces out of the header but did not fix the issue. Have you come across this before or found a solution?

Assembly used: 2011 Q1 315.40

similar issue: http://www.telerik.com/community/forums/preview-thread/aspnet/window/missing-close-button.aspx

Please Help

Huge ViewState after upgrading Telerik ORM

We recently upgraded our Telerik.Web.UI.DLL and OpenAccess ORM to the latest versions and found that our ViewState for each page jumped significantly - example from 8KB to 200KB. This was across the board on almost all our pages.

After much digging around we found that this was being caused by the StoreOriginalValuesInViewState property of the OpenAccessDataSource object, which defaults to true if not set. I could not find anything in the forums or the Support site about this issue, so I thought this might help somebody else that runs into this. Setting this value to false for each data source allowed our viewstate to go back to normal.
