Hi telerik,

I just downloaded a trial version and fired up vs2010.

When selecting Create New Project, choosing C# RadControls WPF Application, the Project Configuration Wizard opens.

Components as well as Themes are empty lists.

Download shown an error message: Error retrieving latest version information. Please, try again later or contact the Telerik team.

Browse does not appear to find anything of relevance, I've tried some of the directories of the installation, but do not know what I should be looking for.

What do I need do to make the download working?

Hello everybody, my name is Alvaro and I am having the following problem:

I am making a Radchart showing in Stacked Bar100 some information about some forms. Well, the problem comes in the instruction below.

            try
            {
                Stream imagen = RadChart1.Save(120, 120);
            }
            catch (Exception e) { throw e; }

++throws this error:

[System.ArgumentOutOfRangeException] = {"The parameter value must be greater than zero.\r\nParameter name: pixelWidth"}

And if I try directly to do the following:

            try
            {
                Stream imagen = RadChart1.Save();
            }
            catch (Exception e) { throw e; }

++throw this error:

[System.Security.SecurityException] = {"Request for the permission of type 'System.Security.Permissions.UIPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."}

Any idea of why is this happening?

Thanks.

I'm using WPF RadGridView Q3-2010.

My purpose is to set the column template based on its data context while in edit mode. When not in edit mode the column will have triggers to customize the template.

I’m using CellEditTemplateSelector for switching templates according to the data context, but when I tried to enter triggers to the DataTemplate of the GridViewDataColumn.CellTemplate - I found that these triggers don’t work.

I read in this forum that in order to work with triggers on RadGridView, I need to set the ContentTemplate of the GridViewCell within the GridViewDataColumn.CellStyle attribute. After doing so, the triggers started to work, but the CellEditTemplateSelector Stopped working correctly. The Selector chooses the right template but the grid doesn’t use it, Moreover, the Data Context has been changed causing the grid to stop showing data after it enters the Edit Mode.

What do I need to do in order to make the triggers work with the edit template selector?

I'm looking to add a custom control to each FilterCriteria in our RadDataFilter. Ideally, this would be a button to the right of the UserInput control. When pressed, it'll fetch unique values from the database and present them in a list of some sort. The user can then select a unique value and insert it into the UserInput control instead of having to type the value themselves.

I've looked at the documentation regarding custom FilterEditors. It looks like I could create the mapping from EditorTemplateRule to DataTemplate based on the PropertyInfo type instead of the PropertyInfo name. I would then need only a handful of DataTemplates (one per type) instead of hundreds of DataTemplates (we have hundreds of columns to search across).

However, it also seems I'd have to re-implement the stock functionality of the FilterEditors by providing a UserInput control that mimicks the current behavior. For instance, I'd have to handle DateTimes by providing a calendar selector. I'd like to not have to do that. I've been going through the Styles and Templates documentation to see if I can just add a template with a custom control to the right of the FilterEditor, but I'm not having much luck coming up with a solution.

Does anyone have ideas on the best way to approach this sort of customization?

Thanks.

I used a sample project from another post and have a RadGridView as the DropDownContent for a DropDownButton. The Content of the Button is bound to the SeletedItem of the GridView. And I created a ContentTemplate to display a piece of data from the SelectedItem.

How do I display something (a message that says "Select Source" or something similar) when no item is selected in the GridView. Would I use a TemplateSelector?  If so, How? I'm not sure and I've never used TemplateSelector.

Here is my scaled down code for my ddb:



Thanks.

Hey guys!

I have been having trouble getting my RadTreeView to deselect items that I have selected with multiselect.
What am I missing?
