Thank you for writing.
Following the provided information I have prepared a sample project where the RadDock
is used an MDI container
. In the child form there is a RadGridView
bound to the Northwind.Categories
table. In order the grid to fill the entire form's size, you should set the RadGridView.Dock
property to DockStyle.Fill
. Additionally, in order the columns to be spread over the whole grid, you can set the RadGridView.AutoSizeColumnsMode
property to GridViewAutoSizeColumnsMode.Fill
. Please refer to the attached gif file illustrating the behavior on my end.
If it does not suit your requirement, it would be greatly appreciated if you can provide additional information about the exact requirement that you are trying to achieve. Thank you.
I hope this information helps. Should you have further questions, I would be glad to help.
