Question

我想根据gridview的选定行更改两个标签的文本。

我一直收到错误消息，指出公共成员行在linkbutton上不存在

Protected Sub LinkButton1_Click(ByVal sender As Object, ByVal e As System.EventArgs)

    Dim LinkButton1 As LinkButton = DirectCast(sender, LinkButton)

    Dim tour As Label = CType(sender.Row.FindControl("label2"), Label)
    Dim depart As Label = CType(sender.Row.FindControl("label3"), Label)

    test.Text = tour.Text
    test1.Text = depart.Text

    UpdatePanel9.Update()

End Sub

根据您的代码，sender是LinkButton。引用Row时，属性sender.Row将不会出现在链接按钮上。这就是你得到错误的原因。

您希望挂钩SelectedIndexChanged事件，这样您就可以更轻松地访问该行。

Sub MyGridView_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)
    Dim myGrid As GridView = TryCast(sender, GridView)
    Dim selectedRow As GridViewRow = myGrid.SelectedRow

    'do something with selected row as needed from here.....

End Sub
