Example

This example illustrates the use of this member by returning whether the specified column and row are bound to a data source.

string conStr = "Provider=Microsoft.JET.OLEDB.4.0;data source= " + Application.StartupPath + "\\Patients2000.mdb";
string sqlStr = "SELECT * FROM Patients"; 
System.Data.OleDb.OleDbConnection conn  = new System.Data.OleDb.OleDbConnection(conStr); 
DataSet ds = new DataSet(); 
System.Data.OleDb.OleDbDataAdapter da = new System.Data.OleDb.OleDbDataAdapter(sqlStr, conn);
fpSpread1.ActiveSheet.DataAutoSizeColumns = false; 
fpSpread1.ActiveSheet.DataMember = "Patients"; 
da.Fill(ds); 
fpSpread1.ActiveSheet.DataSource = ds;
DialogResult dlg;
dlg = MessageBox.Show("Do you want to check if the column and row are bound?", "IsColumn/RowBound", MessageBoxButtons.YesNo);
if (dlg == DialogResult.Yes)
{
    fpSpread1.ActiveSheet.AddUnboundRows(1, 2);
    fpSpread1.ActiveSheet.SetValue(2, 0, "Daly");
    fpSpread1.ActiveSheet.SetValue(2, 1, "John");
    fpSpread1.ActiveSheet.SetValue(2, 2, "111390");
    fpSpread1.ActiveSheet.SetValue(2, 3, "12 Courtney Place");
}
MessageBox.Show("Row 1 is bound = " + fpSpread1.ActiveSheet.IsRowBound(1).ToString() + " - Column 1 is bound = " + fpSpread1.ActiveSheet.IsColumnBound(1).ToString(),
"IsColumn/RowBound", MessageBoxButtons.OK);
