Changing Worksheet name while exporting to CSV

Hi All,

I am facing a situation here where I need to change the worksheet name of CSV file. I use below code to export my grid to CSV.

grid1.MasterTableView.ExportToCSV();

I don't want to export file to excel (i.e. xls or Excelml). I am using Telerik 2011 Q3. Is it possible to do the same in Telerik 2012 Q1?

Thanks in advance!!!

[Solved] RadAjaxPanel BackColor wont disappear after the AJAX post back

Hi,

I am upgrading 2008 Q3 version of telerik control to 2011 Q3 version in my project in .NET 4.0. I have an issue with the RadAjaxxLoadingPanel in the latest version where it used to work fine with 2008 version.

I have a RadComboBox outside of the RadAjaxPanel which refreshes the grid based on the dropdown selection. When Items selection is changed in the dropdown it will make a Ajax postback to refresh the grid. while the grid is getting refreshed the AjaxLoading panel shows the back color of gray with some transparency set. The grid will not be accessible during the refresh. The gray color disappeared itself and grid became accessible again, once the Ajax is complete in the 2008 Q3 version. But, with 2011 Q3 version the gray color won’t disappear and the grid is inaccessible even after the post back is complete.

Here is the code: Please let me know what needs to be done to get the same behavior in the latest version? Thanks in Advance!!!

Enter Key - ComboBox

I am using RC Q2 2010 Net 4

I am using a combobox as a lookup that automatically fills with data from a SQL Table so that when a user begins typing in the box the data filters. Everything works great as long as the user SELECTS the item from the dropdown list. However, if the user types the exact item in the box and the dropdown filters to the exact text and the user hits the enter key and does not select the item from the list, the box queries all items in the table and not just the item that was typed.

For example, the CB we are using lists data from a user table with a field called LastName.

When the user starts typing 'bro' the box filters the list and shows all users that have a last name that begins with 'bro'

brown
browning
brownly

If the user selects browning from the list, the correct user data is queried and returned.

However, if the user types the entire name browning and hits the enter key instead of selecting it from the dropdown list, all users are returned.

Here is the ASPX code for my ComboBox:

<telerik:RadComboBox ID="rcb_Users" Runat="server" AutoPostBack="True"

DataSourceID="sds_UserList" DataTextField="UserName"

DataValueField="UserName" EmptyMessage="Select User" Height="150px"

Skin="WebBlue" EnableAutomaticLoadOnDemand="True" EnableVirtualScrolling="True"

ItemsPerRequest="10" ShowMoreResultsBox="True">

</telerik:RadComboBox>

Is there a way to alow the use of the enter key?

[Solved] RadListBox Item Height

Hello all

if i put this code into the head section of my master page,
items are 10 pix height as expected, but only on vstudio2008 webdevserver, not on production server (w2k3).

the only differences in ie8 sourcetext compare are things like this: <link href="/WebResource.axd?d=Xv_vuQIqd...blabla
Maybe there is a better way to set the line height of my listbox items, the default height is much too big for my taste.
i am a bit lost...
Any ideas?
