Is there any way to obtain the list of the columns and the visibility from the first control below the columns label?

Hi Alvaro,
You can use the Client-side API exposed by the RadGrid to get its columns on the client - get_columns(). The visibility of each column can be defined using the get_visible() function exposed by the GridColumn object.
Here is a short sample demonstrating the suggested approach:
protectedvoidRadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
(sender as RadGrid).DataSource = OrdersTable();
}
private DataTable OrdersTable()
{
DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("OrderID", typeof(int)));
dt.Columns.Add(new DataColumn("OrderDate", typeof(DateTime)));
dt.Columns.Add(new DataColumn("Freight", typeof(decimal)));
dt.Columns.Add(new DataColumn("ShipName", typeof(string)));
dt.Columns.Add(new DataColumn("ShipCountry", typeof(string)));
dt.PrimaryKey = new DataColumn[] { dt.Columns["OrderID"] };
for (int i = 0; i < 70; i++)
{
int index = i + 1;
DataRow row = dt.NewRow();
row["OrderID"] = index;
row["OrderDate"] = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, 0, 0, 0).AddHours(index);
row["Freight"] = index * 0.1 + index * 0.01;
row["ShipName"] = "Name " + index;
row["ShipCountry"] = "Country " + index;
dt.Rows.Add(row);
}
return dt;
}
I hope this will help you achieve the desired.
Please let me know if any questions remain.
Kind regards,
Doncho
