我有一个会话参数，它从 webgridview1 获取单元格数据并使用它将信息传递到 webgridview2，会话正在正确更新，但在我手动单击重新加载按钮之前不会填充第二个 webgridview

Public Sub WebDataGrid1_CellSelectionChanged(sender As Object, e As Infragistics.Web.UI.GridControls.SelectedCellEventArgs) Handles WebDataGrid1.CellSelectionChanged
    Dim pressName = e.CurrentSelectedCells(0).Text
    Session("PressName") = pressName
    UpdatePanel1.Update()
End Sub

我尝试了一个更新面板，但这也不起作用。
Response.Redirect 带来了一个空白页面，gridviews 消失
了我如何重新加载我的页面，或者让会话再次传递到 webdatagrid？

您显示的代码中没有第二个网格视图的 DataBind。尝试这个

Public Sub WebDataGrid1_CellSelectionChanged(sender As Object, e As Infragistics.Web.UI.GridControls.SelectedCellEventArgs) Handles WebDataGrid1.CellSelectionChanged
    Dim pressName = e.CurrentSelectedCells(0).Text
    Session("PressName") = pressName
    WebDataGrid2.DataBind()
End Sub
