Layout problems

Hi,
I have a problem when loading a layout configuration file im my application at startup and when I choose to change layout:
My layout configuration is a XML file and i use a RadDock and the method LoadFromXml(path), where path is where the complete path where the layout configuration file is present (*.xml).
The file is present and the layout is correctly loaded, but the application performs a bad animation during the layout update.
My Goal is to hide the layout changing animations and to show only the final result with the windows correctly positioned on the RadDock control.
Is there a way to build the layout without showing the intermediate state of the creation process of the layout, but only the final result?

That seems to be the approach I am looking for but don't know what else to set.

I have loaded a DataTable object containing just a column-field of type Binary holding Images.

Please advise. Please provide detail examples if possible. :)

RedDataGridView and Grouping in Virual Mode

Hello,
I have problem with grouping in the RadDataGridView. In my project the grid must be in the virtual mode: (VirtualMode = true) (filling some cells are taken from a list; FieldName property cannot be used), but grouping by some parameter (in the grid) is not working in this mode, since Grouping property is joined with bindingSource controller, which I cannot use (If I understood well the functionality). Thus, it is possible to group data in the virtual mode? If it does, could someone attache a piece of code for me?
Thank.

Limiting Entry to values contained in ComboBox

Hello,

We are using a MultiColumn ComboBox for a drop down list in our app.

I'd like the user to only be able to enter values that are contained in the list.

Currently, they can type anything they like in the box, and save it.

Of course, they can also use their mouse to select an item, but we'd like to prevent them from saving invalid data.

Thanks,

How to seach for text in a column

Is there a simple way to search a column for a specified text and then select the first (then next) row with the text, if found?

(I am aware of the Filter functionality, but that is not what I need here.)

I'm having a hard time adjusting to the object model of the RadGrid, being used to such simple things as MSFlexGrid.TextMatrix(iRow, iCol).

Can you point me to a grahic view of the RadGrid object model?
