解决方案

发现了它。需要设置GridView的EditIndex，然后做一个数据绑定。

 私人小组gvReport_RowEditing（发送者为对象，E作为System.Web.UI.WebControls.GridViewEditEventArgs）处理gvReport.RowEditing
    gvReport.DataSource = CTYPE（会议（gvReport），数据视图）
    gvReport.EditIndex = e.NewEditIndex
    gvReport.DataBind（）
结束小组
 

I am using a GridView and I encountered the click twice on the Edit link to see the edit fields problem. Following advice I am binding my GridView again on the .RowEditing handler. The problem persist that I only see edit fields after my second click on any of the Edit links.

            Session.Add("gvReport", dvAgTarRet_gv)

            end sub

解决方案

Found it. Needed to set the gridview's EditIndex and then do a databind.

Private Sub gvReport_RowEditing(sender As Object, e As System.Web.UI.WebControls.GridViewEditEventArgs) Handles gvReport.RowEditing
    gvReport.DataSource = CType(Session("gvReport"), DataView)
    gvReport.EditIndex = e.NewEditIndex
    gvReport.DataBind()
End Sub
