Grid and Sharepoint Web Parts

[Tarique]

I am trying to build a very simple web part using your grid product.

Code is posted below.  Are there any good references you recommend for getting this to work.

using System;
using System.Runtime.InteropServices;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Serialization;
using System.Data;

using Microsoft.SharePoint;
using Microsoft.SharePoint.WebControls;
using Microsoft.SharePoint.WebPartPages;


using Telerik.Web.UI;

using PmeUtilities;

namespace PmeRisk
{
    [Guid("975f68de-868f-4e53-b5f4-1025a0db6c1c")]
    public class RiskGrid : System.Web.UI.WebControls.WebParts.WebPart
    {

        private HtmlTextWriter textWriter;

        private ScriptManager scriptMan;

        public ScriptManager AtlasScriptManager
        {
            get
            {
                if (scriptMan == null)
                {
                    scriptMan = ScriptManager.GetCurrent(this.Page);
                    if (scriptMan == null)
                    {
                        scriptMan = new ScriptManager();
                        this.Controls.Add(scriptMan);
                    }
                }
                return scriptMan;
            }
        }

        public RiskGrid()
        {
            this.ExportMode = WebPartExportMode.All;
        }
        protected override void Render(HtmlTextWriter writer)
        {
            base.Render(writer);
            textWriter = writer;
        }


        protected override void CreateChildControls()
        {
            base.CreateChildControls();
            try
            {

                RadGrid radGrid = new RadGrid();
                radGrid.ID = "RAD GRID";

                String siteName = SharepointUtils.determineWebURL();
                String riskListName = "Risks";

                DataTable riskTable = SharepointUtils.getListItems(siteName, riskListName, textWriter);
                radGrid.DataSource = riskTable.DefaultView;



                this.Controls.Add(radGrid);

            }
            catch (Exception ex)
            {
                String message = ex.Message;
                String stackTrace = ex.StackTrace;

            }


        }
    }
}

Hi Tarique,

There are lots of clients which have implemented web parts based on RadControls.

Usually the most difficult thing is to set the RadControlsDir property to valid location because it is a bit tricky in SharePoint environment. Fortunately, with the Prometheus versions of our controls you do not need RadControls folder and this part becomes obsolete.

Creating a webpart based should be quite simple - here is a short sample:

public class MyWebPart : WebPart
{
     protected override void CreateChildControls()
     {
           base.CreateChildControls();

           RadGrid grid = new RadGrid();
           grid.ID = "myGrid";
           /* populate your grid based on your requirements */
           Controls.Add(grid);
     }

     protected override void RenderWebPart(HtmlTextWriter output)
     {
           EnsureChildControls();
           RenderChildren(output);
     }
}
Alternatively, you can try adding RadGrid on Init. For more info on building WebParts you can refer to msdn's articles such as Web Parts in Windows SharePoint Services .

Hi Rosen,

I tried what you suggested with no luck.  Does the web.config need to be edited.  Are there any ajax specific instructions that need to be followed.

I added the following line to my web.config.  Please let me know if this is correct.

<

SafeControl Assembly="Telerik.Web.UI, Version=2007.3.1218.20, Culture=neutral, PublicKeyToken=121fae78165ba3d4" Namespace="Telerik.Web.UI.Grid" TypeName="Grid" Safe="True" />

Hello Tarique,

You can refer to this blog post for more information on how to setup Sharepoint to use MS AJAX.
