Can you share Page_Load?

ntitish 8-May-13 2:43am

Page_Load(object sender, System.EventArgs e)
{
if (!IsPostBack)
{

if (Session["UserID"] == null)
{
Response.Redirect("Splash.aspx");
}

string sPatientId = "";
GlobalDiagnosticsContext.Set("PatientId", sPatientId);
GlobalDiagnosticsContext.Set("PageViewed", "MsgInbox Page");
GlobalDiagnosticsContext.Set("PageType", "Web");
GlobalDiagnosticsContext.Set("TimeStamp", DateTime.Now.ToString());
logger.Info("***MsgInbox page***");

cMsgTeset obj = new cMsgTeset();
obj.ResetMessages(Session["UserID"].ToString());

// *********UserNotification reset
SQLHelp dataHelper = new SQLHelp();
string cmdIn = "select * from usernotifications where userid='" + Session["UserID"].ToString() + "' and Flag='NR' and Type='Web'";
DataSet ds5 = dataHelper.ExecuteSelectProc(cmdIn);
if (ds5.Tables[0].Rows.Count > 0)
{
string cmdUpNot = "update usernotifications set count=0,Flag='R' where Type='Web' and userid='" + Session["UserID"].ToString() + "'";
int j = dataHelper.Execute_datamodify_Proc(cmdUpNot);
}
//************

}
}

I think you have a problem with pagersettings because there is no closing tag, It might be problem but I can not see any wrong part for this problem. Can you share your codes after correction of pagersettings tag

Solution 1

I am not sure about Page.DataBind();
this works for me

C#

protected void gridView_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
   gridView.PageIndex = e.NewPageIndex;
   gridView.DataSource = /* Specify your dataset you want to bind here */
   gridView.DataBind();
}

The error means that Only one data source you can apply to the gridview. In your case you are binding the gridview using DataSourceID="sdsInbox" as well as in gvInbox_PageIndexChanging. Delete one databinding, it'll work.
