Dim i As Integer
For i = 0 To Repeater.Items.Count
Dim abc As Label = Repeater.Items[i].FindControl("l1")
手里没vb，看了看好像没错
For i = 0 To Repeater.Items.Count
Dim abc As Label = Repeater.Items[i].FindControl("l1")

你能看懂c#的吧
for (int i = 0; i < Repeater1.Items.Count; i++)
{
label lbs = (Label)Repeater1.Items[i].FindControl("l1");//获取每行的label控件
//你的后续操作
// 使用lbs来获取这一的来l1控件的属性
}
for (int i = 0; i < Repeater1.Items.Count; i++)
{
label lbs = (Label)Repeater1.Items[i].FindControl("l1");//获取每行的label控件
//你的后续操作
// 使用lbs来获取这一的来l1控件的属性
}
追问
