Hi I have a Rad Grid View that I am exporting to excel using the code below. This works fine, but I would like the code to export the grouped data so that excel sees it as grouped data rather than static cells. Is there a way to achieve this?

Thanks in advance.

private void button4_Click(object sender, EventArgs e)

{

ExportToExcelML exporter = new ExportToExcelML(this.radGridView1);

exporter.HiddenColumnOption = Telerik.WinControls.UI.Export.HiddenOption.DoNotExport;

exporter.ExportVisualSettings = true;

exporter.SheetName = "Films";

string fileName = "C:\\ExportedData.xls";

exporter.RunExport(fileName);

}

GridView exception

Hello, recently we began to encounter exceptions using Telerik GridView. Exception message:

System.NullReferenceException: Object reference not set to an instance of an object.
at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add)
at Telerik.WinControls.Keyboard.ChordMessageFilter.CreateInstance()
at Telerik.WinControls.Keyboard.Shortcuts.AddShortcutsSupport()
at Telerik.WinControls.Keyboard.Shortcuts..ctor(Control owner)
at Telerik.WinControls.RadControl.EndInit()

at CreditAdmin.CardAdmin.Controls.Notifications..ctor() in c:\_Projects\CreditAdminTeboil\EmsAdmin\CreditAdmin\CardAdmin\Controls\Notifications.cs:line 17...

It seems like this happens only when we use ALT shortcuts (to navigate trough tabs ant some other functions). Does anyone knows what could be the cause of this problem ?

Form.WindowState from code in RadRibbonForm

Hi,

I am trying to open form maximized depending on DPI settings.

Unfortunately when I try to do that from code-behind (this is Windows Desktop application) I do not have WindowState available.
Form that I use is RadRibbonForm.

Is it possible to set from code how form will be opened?

Thanks,
Oliver

racSchTechs.AutoCompleteDisplayMember = "Name_Full";

racSchTechs.AutoCompleteValueMember = "id_lanid";

but I want to get the "id_lanid" from the items selected. I do not see this functionality.

Thank you!

Expression Editor without the Gridview

I am trying to use your WinForms Expression Editor to validate a formula expression, directly into a Textbox. I do require a list of fields, but I do not need the gridview. Is there anyway to dynamically pass the list of fields and have the editor show without the GridView?
I have attempted with an invisible gridview, but this is rather ugly. Any hints?
Thanks!

EnableAlternatingRowColor property different for master/child possible?

Hi,

I have set the EnableAlternatingRowColor property in my master template to true, and to false for the gid child template. However its seems the grid obeys only the master template setting across all children templates.

Is it possible to set a child template EnableAlternatingRowColor property different from the master template at all?

Regards,

George

How to make Telerik assemblies of different versions coexist?

Dear Support,

Our application uses reflection to load assemblies and open forms to our user in the runtime. Because we are already behind the schedule, we don't have the time to covert old assemblies from 2009 Q3 to 2010 Q1. In order to make use of the bug fixes and features in the 2010 Q1, we want to start our new assemblies with 2010 Q1.

Is there a way to make 2009 Q3 and 2009 Q1 assemblies coexist locally (we don't want to put Telerik assemblies in the GAC)?
