RadForm event for Double Clicking the title bar

I can't seem to find the event that is fired when the Title Bar of a RadForm is double clicked.
My form is maximized at all times and I don't want the user to change the size of the windown by double clicking the title bar. Form should always stay at maximized state and this (this.WindowState = System.Windows.Forms.FormWindowState.Maximized) is not preventing the resize on Title Bar double click.

MaximizeBox property is set to False to prevent the user from clicking the form's maximize button. This part is working fine.

ViewDefinition

How do you reset a grid's ViewDefinition back to the default table view? Setting it to nothing does appear to work.

[Solved] Client Position for RadTreeNode

Hi,

Is there a way to get either the bounds or the client x,y position of a RadTreeNode item so I can point a Tooltip at a tree item? Either that or be able to get the window handle for the tree item so I can use that in the tooltip.Show() method.

Thanks

is there a GridViewDecimalColumn equivalent form RadTextBox or RadMaskedEdit?

Hi,

I would like to have a textbox control (or maskededit) which mimic GridViewDecimalColumn default editor. That is a control that accepts only decimal numbers, that could have a minvalue and a maxvalue, that do not has the need for a mask. Exactly as the GridViewDecimalColumn editor.

thank you
