Rad Grid (issue with RadAjaxManager)

[rahul]

Hi ,

I have a user control in which i am trying to add the  rad grid with google-like filtering options. I deploy the user control in sharepoint in some page layout

The issue is that i get the following error When i try to add the "RadAjaxManager" that is required for  google-like filtering.
If i remove that  RadAjaxManager then the grid works but no filtering  .  I have also used 

RadAjaxPanel  same error.

at Telerik.Web.UI.RadAjaxControl.MoveUpdatePanel(Control initiator, Control updated) at Telerik.Web.UI.RadAjaxControl.PerformRender() at Telerik.Web.UI.RadAjaxControl.OnPageRender(HtmlTextWriter writer, Control page) at Telerik.Web.UI.RadAjaxControl.RenderPageInAjaxMode(HtmlTextWriter writer, Control page) at System.Web.UI.Control.RenderChildrenInternal(HtmlTextWriter writer, ICollection children) at System.Web.UI.Control.RenderChildren(HtmlTextWriter writer) at System.Web.UI.Page.Render(HtmlTextWriter writer) at System.Web.UI.Control.RenderControlInternal(HtmlTextWriter writer, ControlAdapter adapter) at System.Web.UI.Control.RenderControl(HtmlTextWriter writer, ControlAdapter adapter) at System.Web.UI.Control.RenderControl(HtmlTextWriter writer) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)


Please help me out

Can you please share with us some more details as code spinets of the usercontrol implementation, as the provided information does not seems very useful.

Hello rahul,

You should be able to implement Google-like filtering for template grid columns by plugging the implementation of this type of filtering for the last template column on this online demo:

http://demos.telerik.com/aspnet-ajax/grid/examples/programming/filteringtemplatecolumns/defaultcs.aspx

(it uses RadComboBox without load on demand and you need to extend it to support dynamic items loading and suggestions)
