Hi,
Experts, I have following Code To add a Data Table To Work sheet ,
how can i make it suitable to add data to multiple sheet per table i.e. if i pass rather then a table a data set with n number of tables i want n nos of works sheets
private void WriteToExcel(ref System.Data.DataTable dtExcel)
{
if (dgvData.RowCount == 0)
{
MessageBox.Show("GridView is Empty.");
return;
}
tlsStatus.Text = "Export To Excel Strats.... ";
tlsStatus.ForeColor = System.Drawing.Color.DeepPink;
prbExcelGen.Value = 0;
prbExcelGen.Minimum = 0;
prbExcelGen.Maximum = dgvData.RowCount;
prbExcelGen.Step = 1;
prbExcelGen.Refresh();
object objApp_Late;

string[] headers = new string[dgvData .ColumnCount];
string[] columns = new string[dgvData.ColumnCount];
int i = 0;
int c = 0;
for (c = 0; c <= dgvData.ColumnCount - 1; c++)
{
headers[c] = dgvData.Rows[0].Cells[c].OwningColumn.Name.ToString();
//Convert Cell Names To A,B,C...Z , 65+C=CHR(C)=>A WHEN C=0
i = c + 65;
columns[c] = Convert.ToString((char)i);
