get values of a datagrid column when checkbox is checked.

int id;
for (int i = 0; i < grdDisplayAll.Rows.Count; i++)
{
  //Assume that 0th Row of grid named grdDisplayAll contains Checkbox
  if (Convert.ToBoolean(grdDisplayAll.Rows[i].Cells[0].Value) == true)
  {
    id = grdDisplayAll.Rows[i].Cells["Id"].Value;
    //You may use columnIndex of column instead of ColumnName (i.e. Here "Id")

    //Code here to make whatever you want to perform on selected record
  }
}

for (int i = 0; i < grvTableNames.RowCount - 1; i++)
{
if (Convert.ToBoolean(grvTableNames.Rows[i].Cells[0].EditedFormattedValue))
{
string tableName = dataTable.Rows[i][alias].ToString();
wordDataTable = businessLogic.GetTableAttibutes(name, tableName);
wordDataTable.TableName = tableName;
ds.Tables.Add(wordDataTable);
}
}

Hi rahat220,

You can click a button for doing that :

private void button3_Click(object sender, EventArgs e)
{
    for (int i = 0; i < dataGridView1.Rows.Count; i++)
    {
        if (dataGridView1.Rows[i].Cells["DataGridView1_CheckBoxColumn"].Value != null && bool.Parse(dataGridView1.Rows[i].Cells["DataGridView1_CheckBoxColumn"].Value.ToString()))
        {
            // You can insert your code for getting each row data here
        }
    }
}

I hope this help,
:)
