By Creating the checkboxes dynamically in datagrid by using Template Column,checkboxes with same contents are repeating in all rows.So i want to restrict the checkboxes(one or more) in cells(0),cells(1),cells(2) etc...So instead of using itemtemplte,we can create the checkbox dynamically by the following way....Enjoy the coding.....Cheers
BindGrid()
{
Declare an sqlconnection and connect it to the database and fill it in dataset by using sqldataadapter
DataTable dttable = new DataTable();
for (int i = 0; i < ds.Tables["main_type"].Rows.Count; i++)
{
for (int k = 0; k < ds.Tables["sub_type"].Rows.Count; k++)
{
if (Convert.ToInt32(ds.Tables["sub_type"].Rows[k]["type_id"]) == Convert.ToInt32(ds.Tables["main_type"].Rows[i]["type_id"]))
{
if (!dttable.Columns.Contains(ds.Tables["main_type"].Rows[i]["tx_type"].ToString()))
{
dttable.Columns.Add(new DataColumn(ds.Tables["main_type"].Rows[i]["tx_type"].ToString()));
}
}
}
}
DataRow drNewRow = dttable.NewRow();
dttable.Rows.Add(drNewRow);
///bind it to the datagrid
}
public int total_count = 0;
public int cell_count = 1;
protected void DataGrid1_ItemDataBound(object sender, DataGridItemEventArgs e)
{
if ((e.Item.ItemType == ListItemType.Item) || (e.Item.ItemType == ListItemType.AlternatingItem))
{
if (total_count == 0)
{
for (int i = 0; i < ds.Tables["main_type"].Rows.Count; i++)
{
total_count = i;
if (ds.Tables["main_type"].Rows[i]["type_id"] != null)
{
for (int k = 0; k < ds.Tables["sub_type"].Rows.Count; k++)
{
if (Convert.ToInt32(ds.Tables["sub_type"].Rows[k].ItemArray[0]) == Convert.ToInt32(ds.Tables["main_type"].Rows[i]["type_id"]))
{
CheckBox valCheck = new CheckBox();
///For identifying which checkbox is clicked
///you can use valcheck.ID = ....
valCheck.Text = ds.Tables["sub_code"].Rows[k].ItemArray[1].ToString() + "
";
e.Item.Cells[cell_count].Controls.Add(valCheck);
}
}
cell_count++;
}
}
}
