CurrentCellDirtyStateChanged event (Need help)!

private

void dgView_CurrentCellDirtyStateChanged(object sender, EventArgs e)

{
if (dgView.IsCurrentCellDirty)
{
dgView.CommitEdit(DataGridViewDataErrorContexts.Commit);
}
}

I am using this event because i have checkboxes in my datagridview on which i need instant action on its click. This works well for the checkboxes but the problem is when i want to insert a value into one of the cells using my keyboard eg. 10. The event commits the 1 then commits the 0 therefore leaving the value in the cell = to 0. It sets the cell value to 1 then to 0 as you type in 10. That mean when ever I type it erases whole text and replaces it with last typed letter, Hope I am clear to all of you. How canI make this event only operate for my textbox column or any other alternate soltion please!

Hi,

You need to check whether the currentCell is a CheckBoxCell first. If not,don't commit edit.
For example:

void dataGridView1_CurrentCellDirtyStateChanged(object sender, EventArgs e)

{

if (dataGridView1.CurrentCell is DataGridViewCheckBoxCell)

{

Console.WriteLine("CurrentCell is a DataGridViewCheckBoxCell");

}

}

Please let me know if this helps. If i misunderstood you, please feel free to tell me.

Change it to

private  void dgView_CurrentCellDirtyStateChanged(object sender, EventArgs e){
     if (dgView.IsCurrentCellDirty)
      { 
          dgView.CommitEdit(DataGridViewDataErrorContexts.Commit);
          return;
      }
}

Hi Laxman,
Can you post your code, I tried and it worked very well.
And if you dont put return after commit in CurrentCelldirtyStatChanged event , then code below that would execute twice.
