Question

我在更新面板内有一个网格视图，其中有多个绑定字段，最后两个绑定字段，如图所示，单击时显示另一个网格视图，没有回发但下载不起作用，除了我设置了脚本管理器的EnablePartialRendering =“false” 但在这种情况下，updatepanel无法显示绑定字段

enter image description here

我绑定了我的网格

就像在这段代码中一样

    protected void ShowDoc(string sCondition)
    {
    //declare connection by pass connection string from web.config
    SqlConnection sqlcon = new SqlConnection
        (ConfigurationManager.ConnectionStrings["SystemConn"].ConnectionString);

    //declare sql statment  as astring variable

    if (Session["Image"] != null)
    {
        Session.Remove("Image");
    }
    try
    {
        SqlStatment = string.Format("select distinct IssuesNum,DocType,DocTypeSub,DocCode,DocTypeName,Name,IssuesID,TypeID,TypeName,Area,IssuesNumSplited,Year   from [View_ImagesSearch] Where {0}  Order By [IssuesNumSplited] ASC", sCondition);

        //create asql command and pass for it the connection string and sql statment
        SqlCommand sqlcom = new SqlCommand(SqlStatment, sqlcon);

        //create data adaptor to bring data from database
        SqlDataAdapter sad = new SqlDataAdapter(sqlcom);

        // declare dataset to store data from data base in it
        DataSet ds = new DataSet();

        //fill data set with data adabter that contain data from database
        sad.Fill(ds);
        lblDocCount2.Text = ds.Tables[0].Rows.Count.ToString();
        Session["Image"] = ds;
        GvImages.DataSource = ds;
        GvImages.DataBind();

    }
    catch (Exception ex)
    {
        par_ErrorMessage.Visible = true;
        par_ErrorMessage.InnerText = ex.Message;
    }
   }

当我点击名为عرضupdatepanel的命令工作时，显示另一个gridview 但是当iclick项目模板下载不工作时，直到我设置EnablePartialRendering =“False”

Answer 1

在UpdatePanel上调用 DataBind 后，确保您在GridView上调用更新：

GridView.DataBind();
UpdatePanel.Update();

有关其他可能的解决方案，请参阅this。

为什么我的boundfield不能在gridview内使用updatepanel？
