Hi All,

I've not had much experience with the rad controls, but what I see so far is pretty good.

I did some searching online, but either was using the wrong search terms or what I want to do is not possible.

I have a listbox on a page. What I want to do is bind it to a linq datasource with checkboxes filled in from the datasource.

I'm hoping that I can pass in a datasource with 3 columns:

ReceivedEmail: Boolean
ClientID: Int
ClientName: String

True-1-Fred Smith
True-2-Betty White
False-3-Amy Whinehouse

This would produce a list with the three names and the first 2 items checked without any extra work in code...

I was talking to one of the other guys I work with and he said that he usually binds to a datasource and then loops through all the list items after binding has finished and then sets the checked flag..
This seemed a little inefficient, and figured that if the control handled it, why not do it in one go..

Does this make sense..?? Can it be done already..???

Many thanks

ListBox

How to install RadControls we just purchased

I hope this is the right place to post this. We just purchased the DevCraft Complete (Formerly Premium Collection) and I want to install the RadControls for ASP.NET AJAX and create a web form with a Grid. The Grid is what I need primarily right now. I've got a set of webforms with regular ASP.NET 4.0 GridViews, but our staff wants the Header and a couple of columns frozen in place when they scroll the large grid.

Anyway, my question is, "How do I get started?" I've downloaded the Telerik.Web.UI_2012_2_724_Dev.msi file and some other files. Do I just run the .msi file to install it in Visual Studio 2010 and then start dragging controls onto my page?

I've got a new website with just a new Default.aspx page in it right now. I'll do some testing and playing around here, then if possible I'd like to upgrade my existing webforms that have the .Net GridViews. I imagine I'll have to replace the old GridViews with a new RadControl Grid.

Are there any "gotchas" that a newbie would need to know about? Should VS be closed when I install it?

Thanks!

I see no one wants to comment. :( I'm not asking for anything but advice, pointers, suggestions or just general comments. I'd even be happy with a, "Good luck with that."

Double-clicking on TreeView Node to Expand Branch

I've done much reading about double-clicking on a RadTreeView node. Apparently the default behaviour is for this to cause it to expand, showing its child nodes.

On my implementation of the RadTreeView it does not do this. Might this be because I have some server-side code that processes the single-click, which serves to Select the node? If so, please know that I absolutely need to maintain that server-side selection code.

Thus, my ultimate question is this: Is is possible to have a single-click of a RadNode run server-side code BUT have a double-click just expand the node?

Curious,

Robert W.

Databinding Expressions are only supported on objects that have a databinding event.

I need to gain access to the underlying datakey so that when a user selects a row I have some code that select data from a database using the datakey as the primary key into the table. In a standard .net grid Id do this and it works

    
            protected void GridViewArtistName_RowCommand(object sender, GridViewCommandEventArgs e)  
        
                    {  
        
                        if (e.CommandName == "Select")  
        
                        {  
        
                            Guid guid = new Guid(e.CommandArgument.ToString());  
        
                            Session.Add("USERID", e.CommandArgument.ToString());  
        
                            if (UserIDChange != null)  
        
                            {  
        
                                // Call the Event  
        
                                UserIDEventArgs E = new UserIDEventArgs(guid);  
        
                                OnUserId(E);  
        
                            }  
        
                        }  
        
                    }

How can I achieve the same functionality with a telerik grid ?
