C# .NET - check/uncheck DataGridViewCheckbox on selected cell dynamically

How to check/uncheck DataGridViewCheckbox cell on selected cell dynamically

I hope you want to check/uncheck a checkbox that is part of the DataGridViewCheckbox column. 

Then, you would write something like,
bool checked = (bool) ((currentRow.Cells[columnIndex] as DataGridViewCheckBoxCell).value);
if (checked)
{
//do something
}
else
{
//do something else.
}

Hope this helps.

Simply try this-

if( ((DataGridViewCheckBoxCell)e.Rows[0].Cells[0]).Selected = true)
  {
    ((DataGridViewCheckBoxCell)e.Rows[0].Cells[0]).Selected = false

  }
esle
  {
    ((DataGridViewCheckBoxCell)e.Rows[0].Cells[0]).Selected = true

  }


YOu can change index based on your columns.


TRy this and let me know.

Hello,

Set your DataGridViewCheckBoxCell position as per Cells[0]

 

In followning DataGridViewCheckBoxCell is added first position.

 

Added Cell Click event as following way

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)

      {

        DataGridViewCheckBoxCell cell = (DataGridViewCheckBoxCell)dataGridView1.Rows[e.RowIndex].Cells[0];

        if ((bool)cell.Value == true)

        {

          cell.Value = "false";

        }

        else

        {

          cell.Value = "true";

        }

      }

 

 

 

Hope this helpful!

Thanks

 

 

 

OOps!....I'm not asking this.

It is Cell selection and i want to change cell value as true or false, which was selected, dynamically.

OOps!....

That's not working b'coz it  will work on cell click event not dynamically as another button click event.

where is you dynemicaly added control?

Oops!..... It is not working..

Actually I want do some task on button click event for those record which DataGridViewCheckBox was Checked.

And after performing task we should cleared of checkboxes. But the problem is which was last selected Cell.
On that Cell does  not work for check/Uncheck both cases.

Could any one resolve this and tell me why does it happen??????

I',m not added control dynamically.
all these are predefined column collection as DataGridViewCheckBox.

did you send me DataGridview design page?
