c# - 在 Gridview 中获取 TemplateFields 的值

Question

我在获取模板字段的值时遇到问题； Gridview在ContentPlaceHolder1中；

我试图在 GridView1_RowCreated 事件中获取值

int RowIndex = GridView1.Rows.Count - 1;
GridView1.Rows[RowIndex].Cells[0].Text = " " + AltKatLinkler;

但是这段代码返回 null 或空。

有我的专栏，专栏索引为0。注意:我使用 SqlDataSource 填充 GridView。没有问题，我可以在浏览器中看到行内容，但我无法从代码隐藏访问。

<asp:templatefield headertext="Haberler" sortexpression="KategoriID" xmlns:asp="#unknown">
    <ItemTemplate>
       < a href='<%# "KategoriGoster.aspx?KategoriID=" + Eval("KategoriID")%>'>
       <%# Eval("KategoriAd")%>
       <%# Eval("Açıklama")%>
    </ItemTemplate>
</asp:TemplateField>

Answer 1

另一种方法

<asp:templatefield headertext="Haberler" sortexpression="KategoriID" xmlns:asp="#unknown">
    <ItemTemplate>
       < a href='<%# "KategoriGoster.aspx?KategoriID=" + Eval("KategoriID")%>'>
       <asp:Label ID="lbKategori" runat="server" Text='<%# Eval("KategoriAd").ToString() %>'></asp:Label>
       <asp:Label ID="lbAçıklama" runat="server" Text='<%# Eval("Açıklama").ToString() %>'></asp:Label>
    </ItemTemplate>
</asp:TemplateField>

代码隐藏

   protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {

            var lbKategori = e.Row.FindControl("lbKategori") as Label;
            var lbAçıklama = e.Row.FindControl("lbAçıklama") as Label;
        }
    }
