The demo examples that are provided all use Integer in their tables, but the code uses a Guid.

I know that I must use the "ConvertUniqueIdToDataSource" method, but I'm missing the actual conversion part.  After researching online, everyone says converting from a Guid to an Integer is not possible.  So I'm not sure where to go from here.  All of my SQL tables use an auto-incrementing integer.

I'm missing this code:

 object ConvertUniqueIdToDataSource(object obj)
        {
            EventId eventId = obj as EventId;
            //if the appointment is added from the scheduler the eventId.KeyValue is Guid
            if (eventId.KeyValue is Guid)
            {
                //return the value that is in your object/dataset
                // --- WHAT DO I PUT RIGHT HERE?  HOW DO I RETURN AN INTEGER?

            }
            //if the appointment is loaded from an object/dataset the eventId.KeyValue is its representation in the object/datase
            return eventId.KeyValue;
        }

Hi.

I have a RadGridView which has a GridViewComboBoxColumn. ComboBoxColumn.DataSource  is an array of Products. Product is an object that has a few properties like Id, Name, and so on. How i can get ComboBoxColumn selected item?

I have tried figure it out by this way
radGridView1.Rows[index].Cells["ComboBoxColumn Name"].Value but it returns only string, not Product object

Can you help me figure it out?

We have been using the PDF viewer and support built into WinForms for some time for viewing PDF files from our vendors.  Just in the last month or two we have been getting documents that are not viewable in the Winforms application but are viewable with Adobe Acrobat.

We are getting the error message: "Error loading document: The encryption method with code 4 is not supported".  

I did a google and see a Telerik enhancement request to resolve this. (with 8 "likes")

Telerik folks -- any idea when/if this might be supported?  Not being able to view some documents is obviously a problem.

Anyone -- If you get documents that aren't viewable is there any process that you have found that would make them work?  (some sort of PDF to PDF conversion?)

Thanks!

Hello, I have problem with mouseover highlighting. It works fine in new version but only when treeView is focused. When it lost focus, mouseover highlighting is disabled. I use it as sidebar menu so I need to work also if it is not focused. Is it solution to this?

I'm pretty frustrated, having lost nearly a day this week because I attempted to use the MultiColumnComboBox control from your toolbox. I'm concerned that there is an increasing quantity of not-ready-to-ship code in the WinForms controls, and I'd like to hear from you on this.

My biggest issue with the combobox was that I could not, after extensive effort, get it to display the embedded grid fully inside the bounding box of the dropdown. On top of this:
1) Properties that don't serialize.
2) Properties that can only be set in code, not the designer.
3) Properties which exist several times in the property tree, none of which have any apparent effect on the control.
4) A Property Builder in the smart tag which crashed Visual Studio half the times I attempted to use it.
5) Deeply buried, commonly used properties (Why is Columns buried so deep in the tree? Because you have a property builder? Whoops. Crashed again).
6) Almost no documentation on the correct use of the control.
7) ((Telerik.WinControls.UI.GridTableElement)radGrid1.RootElement.Children[0]).Padding = new Padding(0);  (!!!!)

I have a sample project sitting here, but I guess there's no way to attach it on the forum. It wouldn't show you anything more than what you see the moment you drop the control on a form anyway. Why is the scroll bar for the grid truncated by the bounding box of the dropdown? It looks amateur.

I have solved my issue. I reverted to using a winforms combobox, and concatenating my fields with commas. It looks better than the radcontrol did.

I'm deeply frustrated, but the only reason I'm writing this, and putting it on the public forum, is that I have had a real respect for the _quality_ of Telerik's products and support, and I'd like to see things get better. Is there an explanation? What can I do to help?
