I have defined a group in a RadGridView using the following code:

The user is able to expand and collapse the group by clicking on the arrow just before the group header. However, the user has requested to be able to expand/collapse the group by clicking on the group header itself.

How can I programmatically raise the event necessary for a RadGridView's group to expand and collapse when the user clicks on the header (not just the arrow)?

Thanks in advance for any help you may provide,

Hector

I'm writing a desktop app that will be used on a single machine, single user (at a time).

It will need a database but the data is never likely to get beyond 100,000 records.

Any recommendations on a back end database?

I'm pretty familiar with SQL Server, so would SQL Server Express be good?

If so, how does that work? Does the SSExpress app need to be running before my app can access it? Or, does the act of accessing the data sufficient?

Thanks in advance for your help.

I've gone through the OpenAccess videos but still don't have a really good understanding of what OA does for me that isn't built into Visual Studio 2010.

Can you point me to a discussion or documentation that explains the big benefit of OA?

Hi, 

Need some special behavior on a textbox column. 
Like doing something in the textchanging event, keypress event and validation event.
And i want to be able to set a fixed length on the  text box. 
I need to do for several grids and several columns.
I know that i can do this by subscribing to events on the activeeditor -> textboxitem. But i want to subclass the GridViewTextboxColumn and do it directly, so i dont need to write the same code over and over again.

Can you please help me?

Regards

Ok, so our client wants to type in dates...no mouse at all.

What they would like to do is use tab instead of arrows to move between month/date/year fields. Is this possible?

Thanks,
David

Hi there,

perhaps it is a stupid question, but I don't get it to work and I found nothing in the web.
I have a multicolumncombobox with 3 columns. I want to add a filter, which searches in all 3 columns and displays all results found in one of the 3 columns.
First I found the filterdescriptor class. That worked fine, but it displays only results, which are found in all 3 columns and not in one of them.
Then I tried to get it work with the compositefilterdescriptor. And that does not work for me. Perhaps someone has a hint. Here is my code:

Telerik.WinControls.Data.CompositeFilterDescriptor compositeDescriptor = new Telerik.WinControls.Data.CompositeFilterDescriptor();
compositeDescriptor.LogicalOperator = Telerik.WinControls.Data.FilterLogicalOperator.Or;
compositeDescriptor.FilterDescriptors.Add(new Telerik.WinControls.Data.FilterDescriptor("productNo", Telerik.WinControls.Data.FilterOperator.Contains, cbo_ProductMultiColumn.Text.ToString()));
compositeDescriptor.FilterDescriptors.Add(new Telerik.WinControls.Data.FilterDescriptor("productSearchName", Telerik.WinControls.Data.FilterOperator.Contains, cbo_ProductMultiColumn.Text.ToString()));
compositeDescriptor.FilterDescriptors.Add(new Telerik.WinControls.Data.FilterDescriptor("productName", Telerik.WinControls.Data.FilterOperator.Contains, cbo_ProductMultiColumn.Text.ToString()));
compositeDescriptor.IsFilterEditor = true;
this.cbo_ProductMultiColumn.EditorControl.FilterDescriptors.Add(compositeDescriptor);

Sorry, if it is a stupid question. I'm still a beginner. :-)

I've been having issues getting Telerik controls to display in Visual Studio's designer mode. Some simple controls, like Text Box and Label will be selectable in design mode and have all their properties pop up in the properties pane, but for some like RadGridView and RadPanel they aren't clickable in design view. The only graphical representation I get of them through the design mode is their icon + label appearing in the grey column underneath the rest of the form/user control (like when you have other custom user controls VS doesn't render).

I've read up on some solutions, namely installing Telerik.WinControls.UI.Designer into the GAC through Visual Studio's command prompt and/or referencing it in the project using said controls. I've tried both solutions -- neither have been working. What's odd, is that I followed the same steps in installing those Telerik controls when I had XP running as my Operating System. Now that the firm has been upgraded to Windows 7 it doesn't work. Don't quote me on this, but I think it may do with the extra security permissions given to folders like Program Files that didn't exist in XP.

I know the recommended answer here would be to upgrade to a newer version of WinForms, and while our company does have them, the program I'm working on is several years old and several (11) projects big. Should we update, we'd need to update the GACs on all of the servers that are hosting the program -- this way our users do not have to install/upgrade our applications themselves. Simply put, it would be a very messy situation.

While I found some answers on this, unfortuantely I found nothing recent or that worked. Perhaps my Googling/search skills aren't up to par, but it would be great if someone could help me out here. I'm simply out of ideas at this point.

Thanks,
Eric

Hi, 

Is it possible to add an "browse/edit (...)" button within a dropdown cell. 
I want to be able to edit the selected dropdown value in another form.

If you know how, please provide me with an example :)

thanks in advance.

Hello,

how can I translate the Ribbonbar in other languages, similar the default .net windows forms controls which have a "Language" property...

Thanks.

Best regards.

I'm using the ListView with DetailsView layout and would like to have two "normal/text" columns and one a dropdown column.
I have tried your Custom Items example and got it working, but I dont want all columns to be custom, only (the last) one.

Is it possible to have different column types with the ListView or should I go for the Grid instead?

Regards
Kenneth
