如何找到控制在一个中继页眉或页脚 [英] How to find controls in a repeater header or footer

问题描述

我不知道怎么一会发现控件一个Asp.Net Repeater控件的HeaderTemplate中或FooterTemplate。

I was wondering how one would find the controls in the HeaderTemplate or FooterTemplate of an Asp.Net Repeater control.

我可以访问他们在ItemDataBound事件，但我不知道如何来后让他们（例如以检索页眉/页脚的输入值）。

I can access them on the ItemDataBound event, but I was wondering how to get them after (for example to retrieve a value of an input in the header/footer).

请注意：我贴在这里找到公正，让我记住它（也许其他人可能会发现这很有用）的答案后，这个问题

Note: I posted this question here after finding the answer just so that I remember it (and maybe other people might find this useful).

推荐答案

由于在评论中指出，当您已经数据绑定您直放站这仅适用。

As noted in the comments, this only works AFTER you've DataBound your repeater.

要找到控制在标题

lblControl = repeater1.Controls[0].Controls[0].FindControl("lblControl");

要找到控制在页脚

lblControl = repeater1.Controls[repeater1.Controls.Count - 1].Controls[0].FindControl("lblControl");

使用扩展方法

public static class RepeaterExtensionMethods
{
    public static Control FindControlInHeader(this Repeater repeater, string controlName)
    {
        return repeater.Controls[0].Controls[0].FindControl(controlName);
    }

    public static Control FindControlInFooter(this Repeater repeater, string controlName)
    {
        return repeater.Controls[repeater.Controls.Count - 1].Controls[0].FindControl(controlName);
    }
}
