Hi,

Usercontrol having ms report viewer control and displaying graph. when i using this usercontrol in webparts. Its working fine. but when ever i click on minimize and restore verbs graph is not displaying.

same user control i used MSOWC11 , it generate image graph. when i click on minimize and restore its working fine.

why ms reportviewr not working in webparts. I am using asp.net3.5 and ajax updatepannel. i removed ajax updated pannel and i tryed. same problem i am facing.

Can you help me...... 

I think the problem is how do you Bind your Report with Data from DB in your Usercontrol .. I have used ReportViewer to display reports and create it as a WebPart  before and i don't have any problems with that..

Thanks for yours reply Vinz,

 In UserControl i am binding data using push method. I created xml schema and codebind binding data. How you are binding data either push method or pull method. I will try pull method. 

        ds.ReadXml(Server.MapPath("~/App_Data/IssueList.xml"));
        rptChartViewer.Visible = true;

        rptChartViewer.LocalReport.ReportPath = Server.MapPath("ReportIssue.rdlc");
        rptChartViewer.LocalReport.DataSources.Clear();
        rptChartViewer.LocalReport.DataSources.Add(new ReportDataSource("dsIssue_dtIssue", ds.Tables[0]));
        rptChartViewer.DataBind();

I am binding the Data in PageLoad event of UserControl with Not IsPostBack method.. see my article below about ReportViewer control
