使用gridview將oracle中的數(shù)據(jù)讀取出來其中有兩列隱藏域?yàn)間uid數(shù)據(jù)類型想在想提取guid數(shù)據(jù)在后臺(tái)使用獲取的值為system.byte[] 不為guid 前臺(tái)代碼<asp:HiddenField ID="HiddenOpGuid" runat="server" Visible="false" Value='<%# Eval("TRANSACTIONID").ToString() %>'></asp:HiddenField> 后臺(tái)代碼 protected void grvMonitor_RowDataBound(object sender, GridViewRowEventArgs e) { e.Row.Cells[0].Visible = true; HiddenField hidefield = (HiddenField)e.Row.Cells[0].FindControl("HiddenOpGuid"); e.Row.Cells[0].Visible = false; this.textbox.text=hidefield.value; }該如何解決

TA貢獻(xiàn)1806條經(jīng)驗(yàn) 獲得超5個(gè)贊

<asp:TemplateField HeaderText="...">
<ItemTemplate>
<asp:Label ID="LabValue" runat="server" Text='<%# Eval("TRANSACTIONID").ToString() %>' Visible="False"></asp:Label>
</ItemTemplate>
</asp:TemplateField>

//放一個(gè)隱藏的Label然后找到它，直接取它的Text不行嗎？
    protected void grvMonitor_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            Label LabValue= (Label)e.Row.FindControl("LabValue");
            //LabValue.Text =？？
        }
    }
