Hello, I've an issue with client-side databinding of a RadGrid. In fact, when I do a .set_dataSource(<dataSource>) and a .dataBind(), data is successfully loaded in the RadGrid but the length of the property _dataItems doesn't change.

Here is the code of the RadGrid:

Here is the code executed in order to load data in the RadGrid:

Example to explain you more clearly my issue:
At the first client-side loading, 126 rows are binded in the RadGrid and selected. So the method .get_dataItems() and the method .get_selectedItems() returm 126 items, it's good. But at the second client-side loading, 4 rows are binded in the RadGrid and selected. The grid display 4 rows so it seems to be good again.. but in fact, when I try to do .get_dataItems() or .get_selectedItems() it returns 126 items again! The 4 first items in _dataItems property are the 4 correct items but there're 122 other items (old items).
I tried to manually delete all items in property _dataItems of the grid but it doesn't work.

I need to know which items are selected so it's a real problem.

Thank's for your help.

 

 

 

How can I create a a rotator with "FormCode" mode while being able to start that rotator automatically when the page loads? I need a complete sample code for the call.

I've used the following JavaScript/JQuery code for FormCode management:

 

And the following code for the calls:

 

 

 

 

 

 

 

 

 

However, I cannot start the rotator on the page load. Tried to use this code in the in the MyRotator_DataBoud event, but did not work either:  

 

 

 

 

Please show me the code that I need to write to start the rotator right after loading the page, and the location where I should place that code. Thank you.

Hello,

I'm opening a RadWindow that allows a user to enter a record into a database.  On the OnClientClose() event, I'm trying to refresh a RadListBox that is in a RadAjaxPanel in the parent page.  This seems like it should be straight forward but I'm not having any luck.  I'm new to web programming so I'm sure I just don't understand something.  I am making it to the code behind once the window is closed so I know the DataBind() is executing.  However, while I see the loading panel displayed the new item does not show up in the RadListBox.  Any ideas as to what I'm doing wrong?  Thanks!

i am using the example of related combo box

http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/multiplecomboboxes/defaultcs.aspx

The only problem, I am having is my combo box is inside the RadpanelBar. I could not figure out what to write for this

function pageLoad()
{
    // initialize the global variables
    // in this event all client objects
    // are already created and initialized
    countriesCombo = $find("<%= RadComboBox2.ClientID %>");    
    citiesCombo = $find("<%= RadComboBox3.ClientID %>");
}

when I do this
$find("<%= RadComboBox2.ClientID %>");    

It could not find the control because this combo box is inside the rad panel bar. can anyone please tell me the script to get the client ID of the control inside the radpanel bar,

any help will be apprecaited.

My company just purchased the Developer license for the ASP.NET version 2011.1.519.35 control set. After complete removal of the trial version and re-installation of the purchased product I am now receiving the error in the attached controlerror.png file. I removed all instances of Telerik from the web.config during the removal of the Trial version. I then copied the new telerik.web.ui.dll and placed it into the solution libary folder and references that dll in the solution. I then ran the 'configure project' selection from Telerik menu to bring my web.config into compliance for this version. No existing controls in the project will render either all controls are showing different errors ( see attached Page1Errors.png) any help would be appreciated.

I am trying to use the NestedViewTemplate with scrollable table.
I would simple like to add a nested template into a table like this one:
http://demos.telerik.com/aspnet-ajax/grid/examples/client/scrolling/defaultcs.aspx

However, I have no luck doing so...

There might be another way to achieve what i'm looking for, which is to have a grid where each row is actually contracted out of 2 rows so the second row of the record (similar to nestedview) will present some additional info (like "comments")

Something like this:

Row1, Cell 1:<name> | Row1, Cell 2:<email> | Row1, Cell 3:<phone> | Row1, Cell 4:<>
Row2, Cell1 (colspan=4) comments are typed here                                                    
Row3, Cell 1:<name> | Row3, Cell 2:<email> | Row3, Cell 3:<phone> | Row3, Cell 4:<>
Row4, Cell1 (colspan=4) comments are typed here                                                    

Is that possible?

On VB.CODE side I wrote:
RadGrid1.MasterTableView.DataKeyNames = {"CustomerID"}
RadGrid1.ClientEvents.OnRowSelected = "RowSelectd"

 

 

I want to read DataKeyNames property inside OnRowSelected event:

function RadGrid1_RowSelected(gridName, rowId) {

 

 

var grid = gridName;  

var oBand = grid.get_masterTableView();

 

 

var row = oBand.get_dataItems()[rowId.get_itemIndexHierarchical()];

 

 

MyLabel.value = oBand.getCellByColumnUniqueName(row, "CustomerID"

 

 

}

In this manner I'll can replace the "CustomerID" static string with the dynamic property obtained from DataKeyNames array[0]

Thanks

 

 

 

 

 

 

 

 

 

 

Hi:

I am looking for documentation on Clientside api for RadTreeList which provides more detail information than can be found on the available documentation. I am looking for Object models,Methods, Details aboutn Event Arguments etc.

Does such document exist or the installed documentation is all that is available.

Thanks

I am using RadControls for ASP.NET AJAX Q1 2011.  I have an application where the Telerik controls have an unspecified skin (that is, there is no SkinID entry in the XML definitions).  I added the following to my web.config:

When I run the application, the CSS attributes (font, color, transperancy, etc.) are applied, but none of the background images that would come from the sprites are rendered.

I also tested
but no joy.

If I go to a control and specify then all is well - the background images are present.  I have reviewed (some of) the documentation, and it seems the web.config entry is a valid method to set the SkinID.  What am I missing?

Further - if a control has a SkinID attribute set, then the web.config entry overrides it (and works).  Please don't tell me I have to set a SkinID on all controls to use the web.config method.
