我正在使用GridView,我在编辑链接上遇到了两次单击以查看编辑字段问题.以下建议我再次在.RowEditing处理程序上绑定我的GridView.问题仍然存在,我在第二次点击任何编辑链接后才看到编辑字段.

    Public Class _Default
        Inherits System.Web.UI.Page

        Protected Sub Page_Load(ByVal sender As Object,ByVal e As System.EventArgs) Handles Me.Load
            If Not IsPostBack Then
                loaddata()
            End If
        End Sub

        Sub loaddata()

        'Get dataview dvAgTarRet_gv



            gvReport.DataSource = dvAgTarRet_gv
                    gvReport.DataBind()
            Session.Add("gvReport",dvAgTarRet_gv)

            end sub

解决方法

找到了.需要设置gridview的EditIndex,然后执行数据绑定.

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
