Question

I have a datagrid getting its data from the database. This datagrid has a column named “Room number”.

I want to add content double click event so that when the user clicks on a specific room number database should be accessed and get the data related to that room number from database and display it on a separate form.

How to access this column by name that is “Room Number”?

private void dgMaster_CellContentDoubleClick(object sender, DataGridViewCellEventArgs e)
{

}

Answer 1

You can get the value of room number by this… i assume here that your room number column is of type int.

private void dgMaster_CellContentDoubleClick(object sender, DataGridViewCellEventArgs e)
{
   int roomNumber = Convert.ToInt32(dgMaster.Rows[e.RowIndex].Cells["Room number"].value);
}

You can also use the e.ColumnIndex but first you have to check that your are on the right index of cell.
