There are many columns. How can I get the value of i?

Add a click event to the checkbox when binding the datalist.
e.Item.FondControl ("checkBoxID"). Attributes.Add ("onclick", "doSomeThing ('" + e.Item.FondControl ("lableId"). ClientID + "'");

The above method does not work, is there any?

Hehe, I wrote a bit wrong, I modified it, the test was successful, remember to check out in time:
<asp: DataList id = "DataList1" runat = "server" OnItemDataBound = "init">
<ItemTemplate>
<asp: CheckBox ID = t1 Runat = server />
<asp: Label ID = l1 Runat = server>
<% # DataBinder.Eval (Container.DataItem, "b")%> </ asp: Label>
</ ItemTemplate>
</ asp: DataList>
<script language = javascript>
function doSomeThing (objName) {
  alert (document.getElementById (objName) .innerHTML);
};
</ script>


Here is the background code:
public void init (object sender, System.Web.UI.WebControls.DataListItemEventArgs e)
{
CheckBox cb1 = (CheckBox) (e.Item.FindControl ("t1"));
Label lb = (Label) (e.Item.FindControl ("l1"));
cb1.Attributes.Add ("onclick", "doSomeThing ('" + lb.ClientID + "');");
}

for (int i = 0; i <DataList1.Items.Count; i ++)
        {
            CheckBox chk1 = (CheckBox) DataList1.Items [i] .FindControl ("CheckBox1");
            if (chk1.Checked)
            {
              Label lb = (Label) DataList1.Items [i] .FindControl ("Label1");
            }
        }
   Response.Write (lb.Text);
