Question

Button_click中修改嵌套在Repeater中控件

protected void Button2_Click(object sender, EventArgs e)
{
string[] userselect;
string[] trueanswer;
userselect = new string[mn.Rows.Count];
trueanswer = new string[mn.Rows.Count];
for (int i = 0; i < mn.Rows.Count; i++)
{
RadioButtonList xz = (RadioButtonList)this.Repeater1.Items[i].FindControl("RadioButtonList1");
userselect[i] = xz.SelectedValue;

trueanswer[i] = mn.Rows[i]["answer"].ToString();
Label xs = (Label)this.Repeater1.Items[i].FindControl("Label3");
if (userselect[i] != trueanswer[i])
{
xs.Visible = true;
}
else
{
xs.Visible = false;
}
}
mn为Datatable 前面repeater的datasource已经置为mn
这段代码我放在Button_click中实现不了 运行都没反应的
希望高手能指教下应该放在哪 怎么放以实现这个功能

Answer 1

是不是应该在Repeater控件的ItemDataBound事件中去做？
我想没反应是不是因为你找控件的时候repeater还没有建立文档结构。

button_click留空，只当他是个提交按钮就行
