Changing elements' colors with Visual Style Builder

I want to say that you've done a great job and your controls look amazing. Now I'm trying to change one of the RibbonBar themes with your Visual Style Builder and I'm a little bit confused.
I have a hierarchy of Chunk - ElementWithCaptionLayoutPanel - FillPrimitive. If I want to change the BackColor of the chunk item which BackColor property I have to change? The BackColor of the Chunk, the BackColor of the ElementWithCaptionLayoutPanel or the BackColor of the FillPrimitive?

Tools - VSB, Control Spy, Shape Editor

Dynamically calculate cell values

Dear everybody,

my request is it to dynamically calculate cell values.

I feed my RadGridView with a dataset or datareader. I am looking for an event which gets fired while data is bounded. The method shall allow me to modify the current cell value based on a calculation of other cells. Something similar like excel also provides with the formula stuff.

Is there any way you can help me?

I also tried events like cellvaluechanged, cellvalidation,valuechanging and the other stuff.

Thanks for a quick reply.

best,

RadGroupBox children dock problem

Hi,

I am experiencing a problem with RadGroupBox.

Scenario...

I have added a radgroupbox in a table layout panel, and set its dock state to fill, so that now it fills a single cell of a table layout panel.

Now i want to add some controls to radgroupbox and want them to resize accordingly as my RadgroupBox resize on my form resize.

So i add a table layout panel to radgroupbox and sets (table Layout panel) dock property to fill but problem arises.

Problem...

When i fill the table layout panel it fills the whole radgroupbox container including the header, footer boundaries etc.

In a standard group box the table layout panel should only fill the allowable control container not the whole radgroupbox container...

Any solution to this..

P.s. I am attaching some pics..

Thank you

RadDock theming

Hello,

Our MDI Application has a RadDock in the main workspace.
The theme has been reset.
I allow the users to choose a theme for the application, and on choosing the theme, all of the controls have the theme applied correctly.

If the user choosers Office2007Silver, then the background colour of the RadDock changes correctly to a silver/grey colour.
On all other themes, the background colour stays the default blue.

I'd like it to change together with the theme choice correctly. My available themes to choose are:
Office2007Silver
Default
Breeze
Desert
Vista

If this is not possible, I'd like to just set the background colour to a default of my choice, but choosing a new background colour for raddock (or the document container or dock panel) doesn't seem to make any difference.

Thanks

sorting RadListBox

Hi,

I have a RadListBox that I fill with just some strings, like this

    
            RadListBoxItem item = new RadListBoxItem(str);  
        
            listBox.Items.Add(item);

I want this ListBox to stay sorted, so I set

    
            listBox.Sorted = Telerik.WinControls.Enumerations.SortStyle.Ascending;

Yet, the string are not sorted. What am I missing?

I tried listBox.Items.Sort. The string are sorted, but then selection is screwed up. Clicking the first item in the list will select the actual first item added to the list.

RadComboboxElement change datasource does not work

Hello everybody,

we are using RadControls for WinForms Q3 2009 SP1 and want to change the items of a ComboboxColumns editor by the value of the cell of another column.

For this in GridView.CellBeginEdit we set the editors element to the filtered datasource and expected the Comboxbox just to show the items of the filtered datasource BUT it shows all items of the original unfiltered datasource.

RadComboBoxEditor editor = m_gridView.ActiveEditor as RadComboBoxEditor;
if (null != editor)
{
((RadComboBoxElement)(editor.EditorElement)).DataSource = filteredDataSource;
}

Did we make a mistake or is it just a bug???

Greetings from Berlin, Germany
