For creating and adding Dynamic templated column using Itemplate interface

First have to override the OnIt() method and then we can add the TemplatedColumn in it for creating check box control.

protected override void OnInit(EventArgs e)

{

base.OnInit(e);

// Create a templated column

TemplatedColumn col = new TemplatedColumn(true);

this.UltraWebGrid1.DisplayLayout.Bands[0].Columns.Add(col);

col.Key = "CheckBoxCol";

col.Header.Caption = "";

GridHeaderTemplate tempHeader = new GridHeaderTemplate();

// Set the header template.

col.HeaderTemplate = tempHeader;

this.UltraWebGrid1.DataSource = LoadGrid();

this.UltraWebGrid1.DataBind();

}

/// Class with implementing the ITemplate

-----------------------------------------------------------

public class GridHeaderTemplate : ITemplate

{

public void InstantiateIn(Control container)

{

// Cast the container to a HeaderItem

HeaderItem headerItem = (HeaderItem)container;

CheckBox checkBox = new CheckBox();

CheckBox cb = new CheckBox();

cb.ID = "headerCB";

cb.Attributes.Add("onclick", "HeaderCheckedChanged();");

headerItem.Controls.Add(cb);

}

}
