I currently have to listbox that both use the same template.  Instead of using a list of values like the demo code, I am pre-populating both boxes with some initial data.  When I transfer an item from one box to the other, the values are not updated.

When using the item list in the html, the item bind on the '_Transferred' method appeared to update these values using the same templates.

The problem is when I switched it to use the list from the database instead of the HTML list.

How can I get the data to show (bind) when transferring in this manner.

Thanks.

hi,

My name is Francisco, I update 2010 Q2 to 2011 Q2 ASP NET and my grid don't work, before update working fine.

When i click edit button of a row, show me a error in the status bar of Internet Explorer version 8.

The error message is:

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Invalid postback or callback argument.  Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page.  For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them.  If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

Can you help me please.

Regards....

In the markup below you'll notice I've set everything to 0pt padding, yet still I get padding and cannot get a border line to go all the way across (see screenshot.) What do i need to do to remove all padding in RG custom header?

Hi developers,

I'm using the RadGrid's filter and it's working well. The problem is that I need to translate the options of the filter menu (Starts with, Contains, Equals to). How can I do this? I need to translate the menu to brazilian portuguese (pt-BR).

Hello,
 i would like to ask if it's possible to export the data of the cloud(item-name , weight) to an excel, maybe with the help of a button?

I have a RadGrid within a RadWindow. The Grid actually lives in a separate ASPX file that is called into the RadWindow. The issue I'm having is that once I go into insert mode I can't go into edit mode unless I close my RadWindow and reopen it. If I choose edit mode first I have no issues. It only happens after I go into insert mode at any point, even if I don't actually insert a record.

On a side note I also have the issue that my insert popup window won't close after clicking the "Save" button.

Below is my code:

ASPX



C#



Any help is greatly appreciated.

Hi there

I have a RadTreeView which binds to a HierarchicalDataSource fine, and I can instantiate a template for the node OK too. The template consists of a RadAjaxPanel that contains an ASCX user control. This all works fine too. My problem is I want to databind a Label web control in the templates' user control to the Content field of the dataitem for each node.

Because the dataitem is only available in the NodeDataBound handler, I reckon I need to get a reference to the Label in the NodeDataBound handler. The problem is, the NodeTemplate property is 'Nothing' when I examine the properties of e.Node from the event arguments. Therefore I don't think I can get a reference to controls in the template at this stage.

Can someone advise, how should I get a reference to the node template at the same time as I can get to the nodes DataItem - the two never seem to be populated at the same time.

Thanks if you can help.

Regards
 

Hi all,

my application has ASP and ASP.Net pages,all asp.net pages has  a user-Control which neary has 40 rad-combo in it..

My Problem is after  navigating few pages in my application using Menu or links provided in the page then click the small arrow near browser back button  i can see only Previous page,because of this user is able to navigate back only  one time after that back button is getting Disbled.
example:
suppose that i have 4 pages logon,A,B,C and A is my landing page after login
in page A when i click arrow near  browser back button  then i can see login page
now im navigating to Page B from Page A, if i click arrow near  browser back button  then i can see only A inseted of A and Logon
now im navigating to Page C from Page B, if i click arrow near  browser back button  then i can see only B inseted of  B,A and Logon

on commenting  the code which binds data for rad-combo's and  trying the same seniro as above  can see all pages i navigated.
im Using radcombo.Bind() to bind data to these drop down

and one more thing is my user-Controls gets executed every time in the page so all the binding functionalty is all getting execcuting again...

 i am thinking because of increase in  page size this is happing.

as my applicaton has lot of reports,back button  is vey important to us
please help me fixing this.???

Thanks,Harin
