Hello ,

My Webpart code is :

RadGrid grid = new RadGrid();

private ScriptManager sm;

public GPSInfo()

{

this.ExportMode = WebPartExportMode.All;

}

protected override void OnLoad(EventArgs e)

{

this.EnsureChildControls();

}

protected override void CreateChildControls()

{

base.CreateChildControls();

if (ScriptManager.GetCurrent(this.Page) != null)

{

this.sm = ScriptManager.GetCurrent(this.Page);

}

else

{

this.sm = new ScriptManager();

this.Controls.Add(this.sm);

}

this.grid = new RadGrid();

this.Controls.Add(this.grid);

this.grid.AllowAutomaticDeletes = true;

this.grid.AllowAutomaticInserts = true;

this.grid.AllowAutomaticUpdates = true;

this.grid.AllowMultiRowEdit = true;

this.grid.AutoGenerateColumns = false;

this.grid.AutoGenerateDeleteColumn = true;

this.grid.AutoGenerateEditColumn = true;

if (this.Page.IsPostBack == false)

{

//SqlDataSource dataSource = new SqlDataSource("Data Source=ARDENT-07ET5GCW;Initial Catalog=WSS_Content_120;User ID=sa;Password=sa", "SELECT id,Name FROM InfoForm");

//dataSource.ID = "SqlDataSource1";

//this.grid.DataSourceID = "SqlDataSource1";

SqlDataSource dataSource = new SqlDataSource("Data Source=ARDENT-07ET5GCW;Initial Catalog=WSS_Content_120;User ID=sa;Password=sa", "SELECT id,Name FROM InfoForm");

//dataSource.UpdateCommand = "UPDATE testdata SET id=@id, Name=@Name WHERE id=@id";

//dataSource.DeleteCommand = "DELETE FROM testdata WHERE id=@id";

//dataSource.InsertCommand = "INSERT INTO testdata VALUES (id=@id, name=@name)";

this.grid.DataSource = dataSource;

this.grid.DataBind();

}

protected override void Render(System.Web.UI.HtmlTextWriter writer)

{

this.sm.RenderControl(writer);

this.grid.RenderControl(writer);

}

And my webConfig coad is :

<!--

Hi Rahul,

Have you gone through the following article and related help topics on integrating RadControls into Sharepoint:
http://www.telerik.com/help/aspnet-ajax/create-ajax-enabled-sharepoint-webpart-radcontrols.html

Do take a look at it and try implementing the following changes to your code:

1. Add the code to the OnInit event, needed for ajax to work properly with the web part.

2. Add the script manager control in the OnInit event as explained in the article.

3. Remove the EnsureChildControls from the OnLoad method - it is not needed.

4. Remove the Render method - and instead add both the grid and the SqlDataSource controls to the Controls collection of the web-part in the CreateChildControls() method.

5. Remove the call to the grid's DataBind() method from the CreateChildControls() method.

Hope it helps.
