我想根据网格视图的选定行更改两个标签的文本。

我不断收到错误消息，指出链接按钮上不存在公共成员行

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

原文

I want to change the text of two labels based on the selected row of a gridview.

I keep getting an error that says the public member row does not exist on linkbutton

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 是一个LinkButton。当您引用 sender.Row 时，链接按钮上将不存在 Row 属性。这就是您收到错误的原因。

您想要挂钩 SelectedIndexChanged 事件，这将使您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

According to your code, sender is a LinkButton. The property Row won't exist on a link button when you reference sender.Row. That's why you get the error.

You want to hook into the SelectedIndexChanged event, which will give you access to the Row more easily.

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
