Hi Palli,
Thanks for your reply,
yes, you are right, i am talking about DataGridViewCheckBoxCell.ThreeState
actual functionality is,
At first gridview will display unchecked checkboxes in first column,
when i click on unchecked checkboxcell it should change to indeterminate state and,
when i click on checkboxcell having state indeterminate, it should get checked and then on click unchecked.
i am trying achieve this by coding but facing some problems,
Please, Explain default behavior of DataGridViewCheckBoxCell.ThreeState.
