Question

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，但直到我手动点击重新加载按钮才会填充第二个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，但这不是正常工作 Response.Redirect打开一个空页面，其中gridviews已经消失了我怎样才能重新加载我的页面，或者让会话再次进入webdatagrid？

您所显示的代码中没有第二个网格视图的DataBind。试试这个

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

会话参数在重新加载之前不会通过
