[Solved] Add a RadGrid to GridTemplateColumn in GridTableView

[Gijo]

Hi,

I am trying to add a RadGrid to GridTemplateColumn in GridTableView  . But it doesn't show up. Below is the code snippet. Am I missing something.

Thanks,
Gijo Joseph.

                            GridTableView tableView = new GridTableView(radGrid1);

                            if (lastAddedDetailTable.ID == "RadGrid1")
                            {
                                radGrid1.MasterTableView.DetailTables.Add(tableView);
                            }
                            else
                            {
                                ((GridTableView)lastAddedDetailTable).DetailTables.Add(tableView);
                            }

                            //tableView.ItemsCreated += new GridItemEventHandler(radGrid1_ItemCreated);

                            //tableView.Width = Unit.Percentage(100);
                            //tableView.Font.Bold = true;
                            //tableView.BorderWidth = 2;
                            //tableView.BorderColor = System.Drawing.Color.Red;

                            if (filterElement.Attribute("parameters") != null)
                                tableView.Name = filterElement.Attribute("parameters").Value;

                            if (filterElement.Attribute("dataKeyNames") != null)
                                tableView.DataKeyNames = filterElement.Attribute("dataKeyNames").Value.Split(',');



                            string[] columnNames = filterElement.Attribute("columns").Value.ToString().Split(',');

                            foreach (string columnName in columnNames)
                            {
                                GridBoundColumn boundColumn = new GridBoundColumn();
                                tableView.Columns.Add(boundColumn);
                                colName = columnName;
                                if (colName.Contains("[F]"))
                                {
                                    boundColumn.Visible = false;
                                    colNamecolName = colName.Substring(0, colName.IndexOf("[F]"));
                                }
                                boundColumn.UniqueName = colName;
                                boundColumn.DataField = colName;
                                boundColumn.HeaderText = colName;
                                boundColumn.HeaderStyle.Font.Bold = true;
                            }

                            GridTemplateColumn templateColumn = new GridTemplateColumn();
                            tableView.Columns.Add(templateColumn);
                            templateColumn.ItemTemplate = new GridTemplate(filterElement.Attribute("name").Value);

using System;
using System.Collections.Generic;

using Telerik.Web.UI;

namespace Data.Reports
{
    public class GridTemplate : ITemplate
    {
         protected RadGrid childGrid;
         private string colName;
         public GridTemplate(string cName)
         {
             colName = cName;
         }

         public void InstantiateIn(System.Web.UI.Control container)
         {
             childGrid = new RadGrid();
             childGrid.ID = colName;
             //childGrid.NeedDataSource +=new GridNeedDataSourceEventHandler(childGrid_NeedDataSource);
             childGrid.DataSource = DBClass.GetDataSP(Grid.referencePath, null);
             container.Controls.Add(childGrid);

         }

         public void childGrid_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
         {
             childGrid.DataSource = DBClass.GetDataSP(Grid.referencePath, null);
         }
    }
}

Hello Gijo,

Thank you for your interest in our products.

To add a template column dynamically in a RadGrid, the grid should be created entirely in the code-behind in the Page_Init event handler. You should also add the column templates in there, so that the template controls can be added to the ViewState.

Please take a look at the Programmatic creation help topic for more information.
