Changing ImageUrl based on custom collection databinding

I am binding a tree to a collection of objects. When the tree is rendered, I would like to display different images before the text of the node,
depending on the type of the node being bound.

I am trying to use the ImageUrlField property to do this, and I receive the following error:

Could not bind to the 'ImageUrlType' property (specified by ImageUrl) while databinding. Please check the DataBindings fields.

(Otherwise the binding, and the hierarchical view works)
The hierarchy model is implemented based on the following example:

Custom Skin Problem with radTextBox

I have copied the outlook skin to the root of my application, renamed to MySkin, then I editted the CSS file and replace all '_Outlook' with '_MySkin' in the Input.Outlook.css (renamed to Input.Myskin.css).

The aspx code is listed below...

My problem is that when I run the application the textbox does not look like the textbox when Skin is set to "Outlook".

So I cannot even start to customize this skin.

Please advise, I have spend far too many hours on this "simple" task.

Grabber not shown on e.Appointment.AllowEdit set to true

I am programming a radScheduler application where you have to register and login to view, create and update new appointments. I have set these properties to radScheduler on login.

            RadScheduler1.AllowDelete = false;
            RadScheduler1.AllowEdit = false;
            RadScheduler1.AllowInsert = true;

// I also have a code that allows users to create appointments just under their UserID

Of course every registered user can only edit and delete his own appointments, so i have created RadScheduler1_AppointmentCreated event, which occurs for every event existing in the current view.

    protected void RadScheduler1_AppointmentCreated(object sender, AppointmentCreatedEventArgs e)
    {
        if (Session["logiran"] != null)
        {
            if (Int32.Parse(Session["status"].ToString()) != 1)
            {
                foreach (Resource resource in e.Appointment.Resources)
                {
                    if (resource.Type == "Uporabnik")
                    {
                        if (resource.Key.ToString() == Session["UserID"].ToString())
                        {
                            e.Appointment.AllowEdit = true;
                            e.Appointment.AllowDelete = true;
                        }
                    }
                }
            }
        }
    }

Everything works fine, I can edit, delete, move the appointment, except for the grabber, which allows the user to resize the appointment. Grabber is just not shown.

I am working on this problem for 2 days now, and I am getting tired of it, so I would be pleased if someone helps me on this one! I just can't fix it.

thanks in advance, Luka

[Solved] Checking if column exists in GridDataItem

This code will throw an exception:

    
                                    GridDataItem dItem = e.Item as GridDataItem;  
        
                                    // rename edit button  
        
                                    TableCell cell = dItem["cmdEdit"];  
        
                                    if (cell != null)  
        
                                    {  
        
                                        Control control = cell.Controls[0];  
        
                                        if (control != null)  
        
                                        {  
        
                                            LinkButton cmdEdit = control as LinkButton;  
        
                                            cmdEdit.Text = "View";  
        
                                        }  
        
                                    }

Instead of handling exceptions, I would rather prefer to check if the column exists prior to accessing it. I couldn't find any simple way of checking column existense by unique name.

Why don't you introduce a method GridDataItem.ContainsColumn(uniqueName) ?
