TextBox problem

Hi,

I'm having a lot of problems trying to programatically a TextBox (or RadTextBox or RadTextBoxElement) control to a Button group inside a ribbon chunk).

Here's what I have:
My application is a content editor (a bit like Flash but not nearly so advanced). So when I click on an Image:
1. I want the "Image" context group to appear
2. I want the the correct properties to appear
3. When I change the properties in the ribbon - the image has to change

Because there are several different items and all of them have the same basic functionality I have created:

// class for handling object operations
public

class BaseRibbonObjectHandler : RadRibbonBarCommandTab

// create the chunk
m_chkPositionAndSize =

new RadRibbonBarChunk();
m_chkPositionAndSize.Orientation = System.Windows.Forms.Orientation.Vertical;
m_chkPositionAndSize.Text = "Position and Size";

// create the ribbon bar group
RadRibbonBarButtonGroup radRibbonBarButtonGroup1 = new RadRibbonBarButtonGroup();
radRibbonBarButtonGroup1.Orientation = System.Windows.Forms.Orientation.Horizontal;
radRibbonBarButtonGroup1.MinSize = new System.Drawing.Size(22, 22);
radRibbonBarButtonGroup1.ShowBorder = true;

// create the labels
RadLabelElement radLabelElement1 = new RadLabelElement();
RadLabelElement radLabelElement2 = new RadLabelElement();
radLabelElement1.Text = "Width ";
radLabelElement2.Text = "Height ";

// create the textboxes
tbSizeWidth = new RadTextBoxElement();
tbSizeWidth.MinSize = new Size(100, 0);
tbSizeWidth.AutoSizeMode = RadAutoSizeMode.WrapAroundChildren;
tbSizeHeight = new RadTextBoxElement();
tbSizeHeight.MinSize = new Size(100, 0);
tbSizeHeight.AutoSizeMode = RadAutoSizeMode.WrapAroundChildren;

// add the controls to the button group
radRibbonBarButtonGroup1.Items.AddRange(new RadItem[] { radLabelElement1, tbSizeWidth, radLabelElement2, tbSizeHeight });

// add the group to the chunk
m_chkPositionAndSize.Items.Add(radRibbonBarButtonGroup1);

// add the chunks to the control
this.Items.Add(m_chkPositionAndSize);

The idea is that in this class I create the tab page, the basic chunks and the basic items:

If I add the TextBoxes (it doesn't matter which kind of TextBox - RadTextBox, RadTextBoxElement or WinForms TextBox) the application hangs up (If I wait about a minute I get a stack overflow exception).
This behavior happens on 3 machines...

A few more facts:
- I have another chunk (I didn't copy the code here) with a button and a combobox and it works ok
- If I add the radTextBoxElement directly to the chunk (and not to a button group) - it works

Am I doing something wrong? Or is this a bug?

Question on custom panels

I was browsing through the new documentation today and noticed something I thought I better get clarification on. In the documentation for Q3 it says that when creating custom dock objects you can either derive from UserDockControl or UserDockForm. In previous versions I was deriving from DockPanel.

What I have still works with my newly installed Q3 but I wonder if I should be changing all of those controls from DockPanel to UserDockControl.

What is the difference? Do I gain anything one way or the other?

Office 2007 Insert Table

Howdy,
I'm looking for a way to mimic the Office 2007 "Insert Table" functionality. I'm looking for any way to mimic the toolbar click (the image below) and ideas on how to implement the inserting of the table into the radtextbox as well.

Thank you

Using custom DataSet

Hi, I use your ragGridControl for the first time. I need to display a list of ActiveDirectory Groups in the grid. I create a custom Dataset with 2 colums (Img and Nom) and put the groups in it.

I set the Grid AutoGenerateColum to false and create 2 colum. When I set the datasource to my custom Dataset, I receive a error telling me that the Colum "nom" are alerady in the table...

Here is my code (sorry for the code directly in the post, but for a unkown reason I can't found the "add code" button in your post toolbar.

Dim Srch As New DirectorySearcher

Dim srchResultat As SearchResultCollection

Dim Resultat As SearchResult

'AJoute les colones

RadGridGroupes.MasterGridViewTemplate.AutoGenerateColumns =

False

Dim imgCol As New GridViewImageColumn

imgCol.UniqueName =

"Img"

imgCol.HeaderText =

""

imgCol.DataField =

"Img"

RadGridGroupes.MasterGridViewTemplate.Columns.Add(imgCol)

Dim txtCol As New GridViewTextBoxColumn

imgCol.UniqueName =

"Nom"

imgCol.DataField =

"Nom"

imgCol.Width = 200

imgCol.HeaderText =

"Nom"

RadGridGroupes.MasterGridViewTemplate.Columns.Add(imgCol)

Srch.Filter =

"(&(objectCategory=group))"

srchResultat = Srch.FindAll

Dim dtTable As New DataTable

Dim dtRow As DataRow

dtTable.Columns.Add(

New DataColumn("Img", System.Type.GetType("System.String")))

dtTable.Columns.Add(

New DataColumn("Nom", System.Type.GetType("System.String")))

dtTable.TableName =

"Groupes"

For Each Resultat In srchResultat

dtRow = dtTable.NewRow

dtRow.Item(

"Nom") = Resultat.Properties("name")(0)

dtTable.Rows.Add(dtRow)

End Sub

RadDropDownButton

How do you get the color on a RadDropDownButton to stay orange as if it was selected like a RadToggleButton? When you hover over the button it changes to orange. How can you do it in code to change it to orange and then back to blue?

Thanks

RadListBox AutoScroll and ScrollIntoView not working

I've added a RadListBox to a form and I add items to the list box at runtime. I'd like the listbox to scroll to show the newest item when it's added.

I tried 2 methods, and neither works:

1.. I've set the AutoScroll to True in the designer.
2. I've implemented the ControlAdded event as follows:

MyList.ScrollControlIntoView(e.Control);

I've tried them together too.

Any ideas?

By the way, scrolling them into view should not move the focus to the listbox.

Thanks...

Animating Progress Bar

I'm trying to make my RadProgressBar control disappear gradually by doing an animation on the Opacity Property.

I found an example of doing animation on a border of a button, but I can't seem to apply the same techniques to the Progress Bar.

Does anyone have an example of animating a RadProgressBar's properties?

Thanks much!
Kevin
