Label lbl = (Label)item.FindControl("lblTitle");lblTitle---请问是哪个label?
新手不会
说：DataListItem item = DataList1.Items[0];
索引超出范围。必须为非负值并小于集合大小。
参数名: index
if (DataList1.Items.Count > 0)
{
DataListItem item = DataList1.Items[0];
}
if(判断类型.......)
{
Label lbl = (Label)item.FindControl("lblTitle");
e.Item.Attributes.Add("OnClick","SelectRow(" + lbl.text + ")");
}
前台
function SelectRow(str)
{
document.getElementById('lbl').value= str;
}
Label lbl = (Label)DataList.items[0].FindControl("lblTitle");
//lbl.Text 就是Datalist里的值
