[Solved] RadGrid Runtime GridTemplateColumns

[Vítor]

Hi all
I has trying to addColumns Dinamycally to a RadGrid
Here is the Code Snippet

 protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                // SET GRID VIEW
                setGridEvoColumns(RadGridEvoStats);
            }
        }

public void setGridEvoColumns(RadGrid Grid,ArrayList years, DataTable Source)
        {

            GridBoundColumn boundColumn;
            GridTemplateColumn gtc;
            StatsColumn sc;
            StatsColumnHeader sch;


            boundColumn = new GridBoundColumn();
            Grid.MasterTableView.Columns.Add(boundColumn);
            boundColumn.HeaderText = "Country";
            boundColumn.DataField = "Country";
            boundColumn.UniqueName = "Country";



            string sufix = "";
            foreach (string year in years)
            {
                sufix = "_" + year;

                gtc = new GridTemplateColumn();
                sc = new StatsColumn();
                sch = new StatsColumnHeader();

                Grid.MasterTableView.Columns.Add(gtc);

                gtc.HeaderTemplate = sch;
                gtc.ItemTemplate = sc;

            }
        }

I create a custom Header and ItemTemplate to the GridTemplateColumn

The Problem is when there are a PostBack on Page the TemplateColumns are cleared (lost their header values as Item values), but bound columns mantain theirs values and Headers.
I'm using NeedDataSource Event to Bound The Grid Also.

I Have already read this Article but it does not have an example with TemplateColumn.

Can anyone help me with this?

Thanks In Advance

Hello Vítor,

Creating template columns dynamically when the grid is declared on the page statically is not supported! you can create the entire grid + column before LoadViewState - ideally in OnInit.
