Hi Boris,

Your below solution is worked for me:

e.Row.Cells[0].Column.CellActivation = Infragistics.Win.UltraWinGrid.Activation.ActivateOnly;

e.Row.Cells[0].Column.ButtonDisplayStyle = Infragistics.Win.UltraWinGrid.ButtonDisplayStyle.Always;

Now tree is visbile and user is not able to type in that cell also.

Thank you very much Boris... :-)

Hi,

I am checking about the progress of this issue. Please let me know If you need any further assistance on this.

Hi,

In my sample, you are not able to type in the cell, but you are able to open the 'UltraTree'. You have already stated that you do not want to user to type in the cell.

Can you please clarify what is your final goal?

Hi Boris,

Sorry for the late reply... :-(

I have tried follwing code chunk.

e.Row.Cells[0].Column.CellActivation = Infragistics.Win.UltraWinGrid.Activation.ActivateOnly; e.Row.Cells[0].Column.ButtonDisplayStyle = Infragistics.Win.UltraWinGrid.ButtonDisplayStyle.Always;

Here, what is happening that , when I set CellActivation to .Activation.ActivateOnly to respected cell, That cell is beconing read only and user is not able to see tree view as well as he is not able to type in that cell.

Can you please suggest on this?
