问题描述

先生您好，

我想问一问我在Itemtemplate字段中使用了dropdownlist的那个网格中有一个网格，我做了一个功能，即

Hello sir,

I would like to ask that there is a grid in that grid I have taken dropdownlist in Itemtemplate field,I made one function i.e.

dropdownlist.datasource=dt;
dropdownlist.databind();
}

我无法填写下拉列表，因为我想在函数中调用ID以从数据库中插入值，即在ItemTemplate内部.

请帮助我纠正我的问题，即如何调用gridview的ItemTemplate内部的下拉菜单ID.

推荐答案

只要您在控件的项目/替代项模板中拥有控件，就无法直接访问控件
您需要通过将方法FindControl()与主控件一起使用来提取内部控件.
即
您的情况就是这样

whenever you have control within a control''s item/alternate-item template you can''t access control directly
you need to extract inner control by using method FindControl() with main control.
i.e.
in your case it will be like this

DropDownList list = (DropDownList) myGrid.FindControl("ddlName");
list.DataSource = dt;
list.DataBind();
