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.

CommandArgument

How can I set the commandArgument for rows in the codebehind ?
Ive tried this, but I get an error

    
            <telerik:GridButtonColumn CommandName="Select"  Text="Select" CommandArgument= '<%# Eval ( "UserID" ) %>' 
        
                                                        UniqueName="SelectButton">  
        
                                                    </telerik:GridButtonColumn>

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 ?

RadAsyncUpload not working in Jquery dialog

Hi,

I have a RadAsyncUpload in a Jquery dialog.

When I click on the control no action is performed in Chrome and Firefox but it is working in IE.

I have added the below code snippet and tried but no success.

        Telerik.Web.UI.RadAsyncUpload.prototype._updateFormProperties = function (form)
    {
        if (form)
        {
            form.enctype = form.encoding = "multipart/form-data";
        }
    }

Is there a workaround for this?

Thanks,
Srini

Closing all other branches after open/toggle node

Hi all,

The WPF Rad TreeView has a property called 'IsSingleExpandPath' to force a treeview to only open one path at a time. If you open a node on a new path, all the other nodes that are on a different path will be closed.
Is there a similar feature for the ASP TreeView without doing messy things in javascript?

customize Alert, Prompt, Confirm windows

Hi,
I found rad window manager "Alert, Prompt, Confirm" windows are very useful.
I read the below features of rad window manager :
Here are the main RadWindowManager's dialogs advantages:

Full customization of the window look to blend into the design of the site, thus increasing usability.
Control the initial size of the popup by providing width and height as extra parameters.
Richer user experience by using HTML content for the dialogs.

I wonder how I can customize the radalert content for example.

I want the OK button be at the center of the window and I want to change the background and the text color and so on.

kindly help me to do that and suggest any useful articles.

regards,
