Hi, a breaking change has happened between 2009Q1 1414 and 2009Q2 SP1 9729.

I add images dynamically to an imagelist. Then I change the ImageKey (tried with ImageIndex as well) on a node. The image is not shown. This breaks my application which worked fine on 2009Q1 1414.

                            private void radButton1_Click(object sender, EventArgs e)         
                    {         
                        imageList1.Images.Add(radTextBox1.Text, Image.FromFile(radTextBox1.Text));         
                     
                        //radTreeView1.Nodes[0].ImageKey = radTextBox1.Text;         
                     
                        radTreeView1.Nodes[0].ImageIndex = imageList1.Images.IndexOfKey(radTextBox1.Text);         
                    }         

Any ideas?

ComboBoxEditor on certain cells

I'm building a property-editor style grid with a readonly column with the name of the property and then an editable column to enter data. Some of the rows have drop-down values where they have their own unique choice of drop-down entries. I can get the comboBoxEditor to appear with the following code:

private void radGridView1_EditorRequired(object sender, EditorRequiredEventArgs e)

List<string> fixedValues = GetFixedValues();

if (fixedValues == null) return; //will use a normal textbox editor for items with no fixedValues

RadComboBoxEditor comboEditor = new RadComboBoxEditor();

(comboEditor.EditorElement as RadComboBoxEditorElement).DataSource = fixedValues;

e.Editor = comboEditor;

e.EditorType = typeof(RadComboBoxEditor);

}

but I am having trouble optimizing the use of the combobox for data entry. The comboBox loses its value as you tab through the cell without changing anything. Basically I haven't found any way to set the selected index or the value. I think it has to do with the Items property never being populated, but I can't get it to populate even though the DataSource is set.

Any ideas?

Thanks,
Adam

AJAX LoadingPanel-Like Functionality

Can you recommend me a method to obtain ajax loadingpanel-like functionality when using WinForms controls? This would help in showing to a user that a background operation is currently in progress on a particular part of the application (for example a control in the bottom-right corner of the application) while still allowing him to browse through the rest of the application. I feel that simply changing the cursor to a waitcursor is not enough, as he has to be hovering the mouse over the usercontrol to realize that work is being done related to that component.

Dock(fill) is incorrect

This may not be the right place for this, but i've never really seen this happen before.

Basically I have a user control (attachment 1). The control consists of a splitcontainer with 2 panels. panel 1 is a radgridview, panel 2 is a listbox. below the splitcontainer is a radtextbox.

In my code i add that control with tabpage.contentpanel.controls.add()
and I use the Dock = DockStyle.Fill;

This does not turn out the way it should.(see attachment 2).
Any ideas why the Dock is not responding properly?

Changing the indentation of treeview

Is there a way to control how far a child node is indented? right now, the treeview looks nice, but takes up too much horizonal space, and I am looking to compress it somewhat.

Thanks.

DateTimePicker AutoSize doesn't resize

Hi!

With the following code, shouldn't the DateTimePicker be resized automatically to display the complete date?

    
            // dtp1 is of type RadDateTimePicker 
        
            dtp1.Format = DateTimePickerFormat.Long; 
        
            dtp1.AutoSize = true; 
        
            dtp1.Value = new DateTime(1982, 9, 20);

Because it doesn't on my computer.
I'm using Vista Business x64, .NET 3.5, Culture "de-DE".
