Hi You can use the following code to count the total number of checkboxes in the checkboxlist have been checked. protectedvoid Button1_Click(object sender EventArgs e) { int numSelected = 0; foreach (ListItem li in CheckBoxList1.Items) { if (li.Selected) { numSelected = numSelected + 1; } } Response.Write(Total Number Of CheckBoxes Selected:); Response.Write(numSelected); } Let me know if u have any doubts.

Hi Use the following code to solve this. You must use this property AutoPostBack =true. Otherwise postback will not happen. form id =form1 runat =server> div > asp : CheckBoxList ID =cblTest AutoPostBack =true runat =server OnSelectedIndexChanged =cblTest_SelectedIndexChanged > asp : ListItem Text =aaa Value =aaa> asp : ListItem > asp : ListItem Text =bbb Value =bbb> asp : ListItem > asp : ListItem Text =ccc Value =ccc> asp : ListItem > asp : CheckBoxList > br /> asp : Label ID =lblAlertMsg runat =server ForeColor =red> asp : Label > div > form > protected void cblTest_SelectedIndexChanged( object sender EventArgs e) { int selectedItemCnt = 0; lblAlertMsg.Text =  ; for ( int i = 0; i { if (cblTest.Items[i].Selected) selectedItemCnt += 1; } if (selectedItemCnt > 1) lblAlertMsg.Text = You have selected  + selectedItemCnt.ToString() +  items. ; }
