This is how you can add a template field in the code behind. You have to handle the WebDataGrid’s Init event, and in the Init event handler (WebDataGrid1_Init in the example) do the following

      protected void WebDataGrid1_Init(object sender, EventArgs e)

      {

            TemplateDataField tempField = new TemplateDataField();

            tempField.Key = "MyTempField";

            tempField.Header.Text = "My Dynamic Checkbox";

            CompiledBindableTemplateBuilder cbtb = new CompiledBindableTemplateBuilder(new BuildTemplateMethod(BuildCheck), null);

            tempField.ItemTemplate = cbtb;

            this.WebDataGrid1.Columns.Add(tempField);

      }

    
     void BuildCheck (Control ctl)

      {

            IParserAccessor acess = ctl;

            CheckBox ch = new CheckBox();

            ch.ID = "check2";

            acess.AddParsedSubObject(ch);

      }
