无法使用 FindControl 在 ASP.Net Repeater 中获取 Label.text

发布于 2024-09-29 08:01:17 字数 542 浏览 10 评论 0原文

我可以访问中继器内文本框中的文本，但无法从中继器内的标签中提取文本值。转发器是从数据表中填充的，行（x）由sqlreader（x）填充，我不知道这是否有什么区别。我不能为此使用 javascript。我需要从代码隐藏中访问标签值。

<asp:label id="weiLabel" runat="server">
  <%#DataBinder.Eval(Container, "DataItem.weiLabel")%>
</asp:label>

是标记，

我可以使用以下方式访问同一行上的文本框：

featTable.Controls(1).Controls(1).FindControl("costText")

并检索 textbox.text，但对标签使用相同的语句给我 {text=""}。

我已经验证 findcontrol 返回的控件的 clientID 是正确的（featTable__ctl1_weiLabel）

感谢您的帮助

I can access the text within a textbox within my repeater, but I am unable to pull the text value from a label within my repeater.
The repeater is populated from a datatable with row(x) being filled by sqlreader(x), I don't know if that makes a difference.
I cannot use javascript for this. I need to access the label value from the codebehind.

<asp:label id="weiLabel" runat="server">
  <%#DataBinder.Eval(Container, "DataItem.weiLabel")%>
</asp:label>

is the markup

I can access a textbox on the same row using:

featTable.Controls(1).Controls(1).FindControl("costText")

and retrieve the textbox.text, but using the same statement for the label gives me {text=""}.

I have verified that the clientID of control that is returned with findcontrol is correct (featTable__ctl1_weiLabel)

Thanks for any help

你可以尝试这样声明你的标签：

<asp:label id="weiLabel" runat="server" Text='<%#DataBinder.Eval(Container, "DataItem.weiLabel")%>' / >

Can you try declaring your label like this:

<asp:label id="weiLabel" runat="server" Text='<%#DataBinder.Eval(Container, "DataItem.weiLabel")%>' / >

您还可以尝试使用数据绑定方法将后面的代码中的值放入标签中。我发现将其放入 html 中更容易调试和清理

 Private Sub repPoliList_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles repPoliList.ItemDataBound

    If (e.Item.ItemType = ListItemType.Item OrElse e.Item.ItemType = ListItemType.AlternatingItem) Then

        Dim dr As DataRowView = CType(e.Row.DataItem, DataRowView)

        Dim weiLabel As System.Web.UI.WebControls.Label= CType(e.Item.FindControl("weiLabel"), System.Web.UI.WebControls.Label)
        weiLabel.text= dr("ColumnFromDatabase").toString


    End If

End Sub

You can also try putting in the value into your label from the code behind using the databound method. I find it a bit easier to debug and cleaner then putting it in the html

 Private Sub repPoliList_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles repPoliList.ItemDataBound

    If (e.Item.ItemType = ListItemType.Item OrElse e.Item.ItemType = ListItemType.AlternatingItem) Then

        Dim dr As DataRowView = CType(e.Row.DataItem, DataRowView)

        Dim weiLabel As System.Web.UI.WebControls.Label= CType(e.Item.FindControl("weiLabel"), System.Web.UI.WebControls.Label)
        weiLabel.text= dr("ColumnFromDatabase").toString


    End If

End Sub
