how to populate columns at design time ?

Hi,
My application has capabitily to design the forms at runtime and ll host to some server. that case I have to give the preview functionality for the radgridview to User.

So when user drag and drop the radgridview from the toolbox itself i need to display the popuation of the required columns with some test data.

I am capturing the event of the drag and drop through Idesignerhost and in that , I had put the following code. The code is executing fine but the databinding is not reflected in the gridview. but if we give datasoure in design time we are able to see the columns with all data. I need the same kind of functionality through code and columns will be decided through code.

DataTable myDataTable = new DataTable();

myDataTable.Columns.Add(

"ControlID", typeof(String));

myDataTable.Columns.Add(

"UpdateField", typeof(String));

myDataTable.Columns.Add(

"DisplayField", typeof(String));

DataRow row;

row = myDataTable.NewRow();

row[

"ControlID"] = "Data";

row[

"UpdateField"] = "Data";

row[

"DisplayField"] = "Data";

myDataTable.Rows.Add(row);

draggedGrid.DataSource = myDataTable;

draggedGrid.DataBind();

Pleae let me know if my question not make sense..

Many thanks in advance.

Two ComboBoxColumns

I have two separate ComboBoxColumns on a RadGrid. The grid is bound to a collection of business objects. I have tried, through the Property Builder and in the code, to set the data-source of each column to a different binding source. The binding sources are the same business object, but different collections.

When editing the values of the columns, the drop downs for the different columns are both showing the same list. Some executions of the application will show one list, other executions will show the other list. Is it only possible to have one source for combobox's dropdowns?

Thank you!

RadLabel Theming

I have created a new theme and in that theme I want the RadLabel to default with a transparent background.

I assumed this was the backcolor of the Fillprimitive , but that has not worked.

I then went as far as to make the backcolor of all the primitives and even the rootelement itself transparent , but still when I apply the new theme the backcolor is always that of 'control'.

So my first question is , is this bugged or am I missing something and secondly which is in fact the correct property to set for this ? (ie: the backcolor belonging to which primitive?)

MenuSeparatorItem Vista Theme

This is probably a ridiculous request but I am at my wits end trying to get this to work. I am using VS2008 and am using the Vista theme on a WinControls RadMenu.

When I add a radMenuSeparator item to my RadMenuItem it does not show up. I have tried modding the original Vista theme in the VisualStyleBuilder but I can not get a separator to appear. Help would be much appreciated.

but when I click on my radGridView and try to select the new theme, it isnt in the list.
Am I missing someting? Wasted almost 2 hours trying around, please give me advise.
Thank you

Tooltip for TextBoxes inside RadGridView

Hi,

I would like to add tooltips to textboxes when I click in a cell inside RadGridView. I subscribed to the RadGridView.CellFormatting event and did the following, but it doesn't seem to work:

private void rgvEditor_CellFormatting(object sender, CellFormattingEventArgs e)
        {
            if (e.CellElement.ChildrenHierarchy.Count > 0)
            {
                foreach (RadElement element in e.CellElement.ChildrenHierarchy)
                {
                    if (element is RadTextBoxItem)
                    {
                        RadTextBoxItem textBoxItem = (RadTextBoxItem)element;
                        textBoxItem.TextAlign = HorizontalAlignment.Center;
                        textBoxItem.AutoToolTip = true;
                        textBoxItem.ToolTipText = "hello";
                    }
                }
            }

Can you help me?

Thanks,
