If you need to check amount of selected items, you probably need this instead of the foreach part. How many you have checked you can see in this property.

List<string> term = new List<string>();

foreach (RepeaterItem item in Repeater1.Items)
{
CheckBoxList CheckBoxList1 = (CheckBoxList)item.FindControl("CheckBoxList1");
foreach (ListItem item1 in CheckBoxList1.Items)
{
if (item1.Selected == true)
{

term.Add(item.ToString());
TextBox1.Text = term.Count.ToString();

}

}

Sir, i have to check checkbox based on textbox value automatically.

What I understood from your code, when you have CheckBoxList1 assigned, you could use TextBox1.Text = CheckBoxList1.SelectedItems.Count and skip the whole foreach part.
