Can't theme some controls in new VSB

I got the latest build (dated 3/9) and while the new VSB is great, there are controls that are not listed as available for creating a theme. RadToolStrip, RadStatusStrip, RadPanel, and on and on and on. When can we expect all of the controls to be listed, or am I doing something wrong and there's already a way to get them listed and I'm missing it?

[Solved] How do the typical grid cells determine cell border color information.

I've created a custom GridViewColumn, along with a custom CellElement, inheriting from GridCommandCellElement, and by default, the GridCommandCellElement does not have DrawBorder set to true. When I set it to true, it draws a border that is a different color than, say, a GridViewTextBoxElement within the same grid. How does the GridViewTextBoxElement know to draw it's own border as the light blue color it is currently drawing it with, as opposed to the black color my custom element is being drawn with, and how can I fetch that value?

Thanks,

David

public void show()

{

inProgressForm.waitingBar.WaitingIndicatorWidth = 0;

inProgressForm.waitingBar.StartWaiting();

inProgressForm.ShowDialog();

}

[Solved] Problem with EditorRequired and CellBeginEdit – cannot set DropDownStyle

Hi

Version: Q2 2010 SP2

I want use custom editor.

So in EditorRequired handler I create RadDropDownListEditor

and in CellBeginEdit I set data source for dropdownlist.

In CellBeginEdit handler I want also set DropDownStyle on DropDownList but I get exception from telerik source code NullReferenceException.

If I do not change DropDownStyle property everything looks ok.

I tried set DropDownStyle on DropDownList in EditorRequired handler but I also got the same exception.

I cannot use just combo box type of column – in the same column I need display different editors.

Check my short source code.

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

using Telerik.WinControls.UI;

namespace GridViewComboBox

{

public partial class Form1 : Form

{

private CompoundAssignmentExpression _list = new CompoundAssignmentExpression();

public Form1()

{

InitializeComponent();

SimpleAssignmentExpression sae = new SimpleAssignmentExpression();

sae.AttributeName = "Test";

sae.Value = "123";

_list.Add(sae);

sae = new SimpleAssignmentExpression();

sae.AttributeName = "Test1";

sae.Value = "xx";

_list.Add(sae);

bsCAE.DataSource = _list;

}

private void radGridView1_CellBeginEdit(object sender, GridViewCellCancelEventArgs e)

{

RadDropDownListEditor comboBoxEditor = this.radGridView1.ActiveEditor as RadDropDownListEditor;

if (comboBoxEditor != null)

{

RadDropDownListEditorElement editorElement = comboBoxEditor.EditorElement as RadDropDownListEditorElement;

editorElement.DataSource = new string[] { "aaa", "bbb", "ccc", "ddd" };

//these lines cause exception:

//editorElement.DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDownList;

//comboBoxEditor.DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDownList;

}

private void radGridView1_EditorRequired(object sender, EditorRequiredEventArgs e)

{

if ((radGridView1.CurrentRow.Index == 0) && (radGridView1.CurrentCell.ColumnIndex == 0))

{

RadDropDownListEditor editor = new RadDropDownListEditor();

//exception here:

//editor.DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDownList;

e.EditorType = typeof(RadDropDownListEditor);

e.Editor = editor;

}

Regards
