string[] s = new string[] { "ramesh","false" };// just for example only

dataGridView1.Rows.Add(s);

{

MessageBox.Show(dataGridView1.Rows[e.ColumnIndex].Cells[e.ColumnIndex].Value.ToString());

//Value is always false only

}

Hi Ramesh,

Based on your post, the cell’s value always return false even the check box is checked when clicking on the cell’s content, right? When the DataGridView is not bound to data, the editing cell won’t commit the value until you move to another. If you want to get the cell’s value in a editing cell, you need submit the value manually. Try something like the following:

Hope this helps

Hello Sir

Thank You For your valuable information

its working from Your code.

Now another my proble in same senerio is i want to make a checked checkbox in

datagridview as uncheck based on some condition(ie if the user selects fist row and it is mandatatory that he has to select the next row which is same as first row if he not select that then ) i want to uncheck that using code.

i tryed by doing reverse engineering like making the isdirty proprtey true but it is thriuging an error its is read only

sample code

routenumber = "rrt";

private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)

if (dataGridView1.IsCurrentCellDirty)

DataGridViewDataErrorContexts.Commit);

if (Boolean.Parse(dataGridView1.Rows[0].Cells[1].Value.ToString()) == true)

MessageBox.Show(dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString());

DataGridViewDataErrorContexts.Commit);
