Hello, I have a drop down list and few panels having textboxes in my design. In the dropdown list, I have embedded few branch names. My procedure is I'll select any branch and write some information in textboxes, then save it.
Its working fine.

Suppose when I select branch1, and write some information in textboxes, in the middle of the process, I will change branch1 to branch2, then when I select different branch in the midst of the process, I need to clear all the controls in my design page. How can I do it? Please do help.

Thank You

Use javascript to clear all fields when value in dropdownlist changed.

JavaScript

<script type="text/javascript">
       function onValueChange()
       {
           try {
               document.getElementById('<%=TextBox_Name.ClientID%>').value="";

           }
           catch(e){alert(e.message);}
       }
   </script>

Call this function on

HTML

onchange='onValueChange();'

event of dropdownlist.

Must add

HTML

ClientIDMode="Static"

attribute to textbox which you want to make clear.
