ASP.NET FormView控件嵌套 [英] ASP.NET Nested FormView

问题描述

我有这样的HTML。

<asp:FormView ID="FormView1" runat="server" DataSourceID="SqlDataSource1">
    <asp:FormView ID="FormView2" runat="server" DefaultMode="Insert" DataSourceID="SqlDataSource2">
       <asp:TextBox runat="Server" Text='<%# Eval("Terms") %>'></asp:TextBox>
    </asp:FormView>
</asp:FormView>

在code上面没有任何错误的作品，但我想条款在文本框中从FormView1的SqlDataSource1代替FormView2（SqlDataSource2）获取。我是缺少在这里？

The code above works without any error but I want to get terms in the textbox fetched from SqlDataSource1 of FormView1 instead of FormView2 (SqlDataSource2). What I am missing here?

推荐答案

您可以访问父对应视图的DataSource值在儿童FormView控件的值作为目前你正在做什么。但是，你设置值的另一种方式。如..

You can access the value of Parent formView DataSource value in child formview as what you are currently doing. But there is another way you set value. like..

protected void ChildFormWiew_DataBound(object sender, EventArgs e)
{
    if (ChildFormView.CurrentMode == FormViewMode.Edit)
    {
        TextBox txtTemrs = ParentFormView.FindControl("Terms") as TextBox;
        ((TextBox)ChildFormView.FindControl("Terms")).Text = txtTemrs.Text;
    }
}
