引用嵌套控件 [英] Referencing nested control

问题描述

我有两个 gridviews - 一个嵌套在另一个中 - 我试图以编程方式设置子网格的数据源，但我不确定如何引用它.

I have two gridviews - one nested in the other - and I am trying to set the datasource of the child grid programmaticly, but am not sure how to reference it.

<telerik:RadGrid ID="RadGridResults" runat="server" AutoGenerateColumns="true" OnNeedDataSource="RadGridResults_NeedDataSource">
    <MasterTableView>
        <NestedViewTemplate>
            <telerik:RadGrid ID="RadGridDetails" runat="server" AutoGenerateColumns="true">
            </telerik:RadGrid>
        </NestedViewTemplate>
    </MasterTableView>
</telerik:RadGrid>

我已经试过了:

RadGrid radGridDetails = RadGridResults.FindControl("RadGridDetails") as RadGrid;
radGridDetails.DataSource = myList.ToList();

但这会返回 NullReferenceException.

But this returns a NullReferenceException.

有人可以告诉我如何做到这一点吗?

Can someone please show how I can accomplish this?

推荐答案

直接对集合进行数据绑定即可:

Just databind the collection directly:

<telerik:RadGrid ID="RadGridDetails" runat="server" AutoGenerateColumns="true"
    DataSource='<%# Eval("myList") %>'>
</telerik:RadGrid>
