How to create a Sorting arrow in the datagrid sortDatagrid does not come with a deafult sort arrow so we have to show our own this code does just that
//call this code in the grid where you call the datagrid bind function
//UpdateColumnHeaders(DataGrid,SortText) eg SortText = "ID ASC"
private void UpdateColumnHeaders(DataGrid dg,TextBox txt)
{
foreach (DataGridColumn c in dg.Columns)
{
string[] arrSort = new string[1];
arrSort = txt.Text.Split(' ');
c.HeaderText = Regex.Replace(c.HeaderText, "\\s<.*>", string.Empty);
if (c.SortExpression == arrSort[0])
{
if (arrSort[1]=="ASC")
c.HeaderText += "  ";
else
c.HeaderText += "  ";
}
}
