Bind your gridview on every postback

I think if EnableViewState="true" for the Grid and Page then its not required to bind the grid in every postback.

WWW, WCF, WWF, WPF, WFC .... WTF

1- Check that the EnableViewState property is not false for the entire page. 2- EnableViewState is not set as false in the web.config file. 3- You are not explicitly setting the gridview Datasoure as null in your postback code.

WWW, WCF, WWF, WPF, WFC .... WTF

I'm sending you the code.In this, when we refresh the page, "gvQA.Rows.Count" shows 0 rows. Here's code: protected void Page_Load(object sender, EventArgs e) { if (Page.IsPostBack == false) { gvQA.DataSource = null; gvQA.DataBind(); BindQues(); } } #region Methods public void BindQues() { try { if (Session["BindData"] == null) { ds = new DataSet(); ds = objGet.GetData(Request["JT"].ToString()); litMsg.Text = "Online Test"; if (ds != null) { if (ds.Tables[0].Rows.Count > 0) { gvQA.Visible = true; gvQA.DataSource = ds; gvQA.DataBind(); Session["BindData"] = ds; } else { gvQA.Visible = false; } } } else { ds =(DataSet)Session["BindData"]; gvQA.Visible = true; gvQA.DataSource = ds; gvQA.DataBind(); } } catch (Exception ex) { Response.Write(ex.Message); } }

I have checked all three points you have sent.But still it doesn't work

[Amit Spadez]

I have already done that. But still problem occurs....... protected void Page_Load(object sender, EventArgs e) { if (Page.IsPostBack == false) { BindQues(); } } #region Methods public void BindQues() { try { if (Session["BindData"] == null) { ds = new DataSet(); ds = objGet.GetData(Request["JT"].ToString()); litMsg.Text = "Online Test"; if (ds != null) { if (ds.Tables[0].Rows.Count > 0) { gvQA.Visible = true; gvQA.DataSource = ds; gvQA.DataBind(); Session["BindData"] = ds; } else { gvQA.Visible = false; } } } else { ds =(DataSet)Session["BindData"]; gvQA.Visible = true; gvQA.DataSource = ds; gvQA.DataBind(); } } catch (Exception ex) { Response.Write(ex.Message); } }
