I have a WinControl RadGridView that is not data-bound to any dataset, we manually create the rows and need be based on certain criteria at the time of load. Clicking into specfic cell, the EditorRequired event get fired where depending on which row we are working with we will present a custom control to fit the needs for that row.
For one of the conditions we are adding a RadCheckBoxEditor to the cell with ThreeState set to true.
Values are getting sent back to the grid row correctly for all three states, but when we try to load the editor again, when it trying to load an Indeterminate the check box always renders as off.
Following the ValueChanged and ValueChanging events; ValueChanged is coming in as Indeterminate, but ValueChanging is showing as false for the new value. This is before any user interaction.
Is there anyway for the checkbox to paint as the "Indeterminate" state.
Thank you
