Export with only currently expanded hierarchal data

I am trying to export a grid with a single level hierarchal data, but the customer only wants to export the second level data that is currently expanded in the web-page, not all of the second level stuff.

Is there a way to export the entire first level of the data in the grid and then only export the hierarchal subsets that are currently expanded in the grid instead of all or nothing?

Thanks,
Jim Harkins

'panes' is null or not an object

We are receiving a javascript error (see subject) when loading a user control that contains a splitter but only when the control is Ajaxed. While debugging, it is finding exception in ScriptResource.axd. The error is at the line: var l=n.panes;

    
            }o.splitbars=k;  
        
            this._resetLastItemClass(g);  
        
            }},_fixItemsIndeces:function(e){var n=this._splitters[e];  
        
            var l=n.panes;  
        
            var d=l?l.length:0;  
        
            var q=n.splitbars;

This exception is new since we upgrade to Q3 2009. Is this a known issue? And as i said, we do not receive an error if Ajax is disabled. I can provide more code is necessary. Thanks!

Incompatibality with microsofts ajaxToolkit ModalPopupExtender

Looks like the form decorator has compatibiliy issues with microsoft's ajaxToolkit ConfirmButtonExtender and ModalPopupextender. For every instance of the extender a bracket "]" appears. If I select "buttons" for ControlsToSkip the issue goes away but now my buttons don't match the rest of my site. This is probably because the popup extender has buttons embedded in it. I see Zone as a ControlsToSkip option. What is a Zone and can I enclose the extender in such a Zone?

How to programmatically create a template column with multiple sub-columns and also add filtering and sorting for all the sub-columns?

Dear All,

I am very new to RadGrid. So please let me know how I can get the following task done. I need to programmatically create an grid with multiple column types. A few columns need to have mulitple sub-columns inside. So as far as my understanding goes, I need to create template column to do this job. So I did the following code and it seems working. However, i do not know how to get the filtering and sorting working with these columns though. Your help will be highly appreciated!

Here is what I have done. The current problem is the the combombox that I added to the filter control does not keep its value after postback. Please let me know what is missing. Thanks.

How to override ComboBox Embedded CSS

I've read all the documents which I've been linked to but I have not come up with the correct syntax yet on how to do this. I am using ASP.Net AJAX 3rd Quarter 2009 suite and I'm trying to override the text of the default embedded CSS for the combobox. I look at the default skin for ComboBox and the styles I want to override are as follows:

.RadComboBox_Default,
.RadComboBox_Default .rcbInput,
.RadComboBoxDropDown_Default
{
font: 12px "Segoe UI", Arial, sans-serif;
color: #333;
}

I've tried puttig a div in front of them and putting them in my own CSS but it does not override the default. Can someone tell me how I'd need to write the css to override the above? Please help!! Thank you.

Installation problem of trial

Hi,

I have a pristine, vs 2008 environment, fully patched. I had problems installing your assemblies and ran gacutil to install the assemblies found in C:\Program Files\Telerik\RadControls for ASP.NET AJAX Q3 2009\Bin35> and C:\Program Files\Telerik\RadControls for ASP.NET AJAX Q3 2009\Bin>.

The error that I am getting is attached. A couple of potential issues that I see are that the assemblies in the bin35 and the bin directories have different version numbers. The project is configured as a .net 3.5 project, however the assembly that vs/telerik is expecting to find is the assembly from the bin directory.

Installation shouldn't be this difficult, I have spent 2 days trying to get this to work.....
