Hi Telerik Team,

I am using Radmenu to display the menu items on the application using following code:
The color higlighted is yellow for the selected Menu item.

Problem Description: When I open one more window from my application (this is one of the menu item to open new window), the selected Menu item is highlighted and happens only in New Window but the old window never highlights again with yellow color and remains white color as usual for all menus.

Please help me on the below problem. I pasted the code what i am using.

<style type="text/css">

.RadMenu_MenuDefault a.rmSelected

{

color: Yellow;

}

.clickedP

{

color: Yellow;

}

</style>

<telerik:RadMenu ID="rmstabmenu" runat="server" Skin="Black" width: 100%; position: absolute;"

OnClientItemClicking="OnClientItemClicking" CssClass="RadMenu_MenuDefault" >

<Items>

<telerik:RadMenuItem Text="Home"></telerik:RadMenuItem>

</Items>

</telerik:RadMenu>

function OnClientItemClicking(sender, args)

{

var item = args.get_item();

var itemtext = item.get_text();

getText(itemtext) ///This picks path for diff menu items

return;

}

RadGrid for ASP.NET NestedView How To Stop multiple views?

I have successfully created a grid in asp.net with a nested view. Since I am new to radgrid I am wondering what is the best way to cause a currently displayed nested view to close before a new one is opened when the user clicks on a different parent row drop down button? I only want one nested view to be open at the time.

Thanks ed.

"RadRotator items request failed"

Hi there,

We have a RadRotator working/loading via a webservice (using the webservicesettings functionality) and all is working well ....except for the following exception that is thrown when a user clicks off the page with the rotator loading too quickly (as a javascript alert dialog):

RadRotator items request failed :
Exception = The server method 'GetRotatorData' failed.

Occurs in FF, IE, Chrome, and occurs regardless of the debug mode setting in web.config

Is it possible to supress/hide, or better, handle this so that the javascript alert is not thrown up to the user?

(Version is that supplied with Sitefinity 4.1 SP1)

Thanks

How can i extend functionality of RadScheduler in sharepoint 2010 ?

Dear telerik,

I've a Calendar list in sharepoint 2010.Now as i didn't want to use in-built sharepoint calendar control, i decided to go for silverlight RadScheduler control.
Now I've integrated silverlight Radscheduler as custom webpart into sharepoint 2010 successfully. Also I am able to do all CRUD operations with Scheduler and sharepoint 2010 calendar list vice versa. i've used silverlight Client Object model of sharepoint 2010.

Now i want to extend my scheduler's functionality by providing purely Dynamic Edit Appointment Dialog window exactly looks like sharepoint 2010 calendar list NewForm/edit form/display form webparts. I mean, when any column/field removes/adds into sharepoint 2010, it automotically reflect into sharepoint 2010 calendar newform/edit form/display form webparts ,but my scheduler is not able to do that. So i decided to build one dynamic edit appointment dialog window which will get all latest list of fields/columns and generate it's related controls and displays into Edit appointment dialog window.

how will i achieve this ? kindly provide source code or anything, i am stuck with this.

regards

Sharepoint Integration

Grid Export Status

I want to update a field in my grid/database to indicate that a record or records have been exported. I am using a custom button to handle the export event rather than the button built into the grid. Is there any way to logically pass on information as to which records have been exported?

Adding child controls to a RadGrid derived class

I have a class derived from RadGrid, to which i would like to add a hidden input and possibly other controls. I'd like to put those at the root level - adding them to the main div (so that these added controls would be siblings of the MasterTableView), but it doesn't seem possible. I've tried overriding CreateChildControls, OnLoad, PreRender, and other functions, at which point i'd try to do a simple this.controls.add(). But the controls i add in this manner never get rendered out to the page - regardless of which function i'm in.

The only way i've been able to render those controls out is if i add them to a cell in the command item. But that command row won't always be visible, so that doesn't seem like a very solid solution.

Any ideas? What's the best way to add child controls to a RadGrid derived class? Preferably without resorting to turning the whole thing into a composite control.

SelectedIndexChanged

Hi,

I'm using a rad combo box within a rad grid and the first column of the grid is the rad combo box. Can you tell me if it's possible that on selected index changed if I can set the text property for a label or text box control outside of the grid? I'm not looking to set the text property for any controls within the grid but out side the grid. I've tried the following with no results.

protected void RadComboBox1_OnSelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)

{

lblSubtotal.Text = "Mytest";

}

Thanks,
Ron.
