2 clicks to check a DataGridBoolColumn ?

[Jarod]

I use a DataGridBoolColumn to format my DataGrid and I was quite surprised by its working : needing to click twice in the column before being able to change the CheckState of my cell:

- first time to select the cell

- second time to act on the checked status

 

Is this the normal working ? There is no way of clicking only one in the cell to directly check or not ?

 

Thanks

It sounds like it might be in tri-state mode, see if there's a property to set tri-state to false.

In fact the DataGridBoolColumn are in tri-state mode (True - False - DBNull value)

THe DBNull value can be refused by a propery (AllowNull to false I think)

But this is a different interaction (wa can see the three mode on the text box (checked, unchecked, grayed) but still after the second click

 

I think that this working is to "copy" the TextBox working:

first click : able to type (space for the DataGridBoolColumn) - all text selected

second mouse action : be able to select, copy, paste, ...
