I am having a problem with disabling DropDownList based on the chice of 1st DropDownList, there is no post back occuring, and it is a template based web app here is the current code:
<script type="text/javascript">
$(function() { var dropDownList1 = $('#<%= ddlUserType.ClientID %>');
var dropDownList2 = $('#<%= ddlMember.ClientID %>'); dropDownList1.change(function(e) {
if ( jQuery("#ddlUserType").val() != "ETOC") dropDownList2.removeAttr('disabled'); e.preventDefault();
else
dropDownList2.removeAttr('enabled'); e.preventDefault(); }
} );
</script>
what is happening now is page is blank and if I remove the above code everything shows, where I am going wrong. here is the plain and final javascript code which worked:
<script language="javascript">
function CheckDropDownState(lstbox)
{
if (lstbox.selectedIndex == 3) { document.forms[0].ddlMember.disabled = 1; }
else { document.forms[0].ddlMember.disabled = 0; }
}
</script>
and thew .aspx code: <asp:dropdownlist id="ddlUserType" runat="server" onclick="CheckDropDownState(this);"></asp:dropdownlist>

View 1 RepliesI am binding months to a list 0-13 items default selection is 0 months duration, and years 0-8 items and 0 years is the default selection.As I know there are always going to be 12 months in a year, I could use selectedvalue or selectedindex without any perceived problem. Is there a reason why I should not use either/or of the two properties to select a list item?

I have an unbound dropdownlist that is populated in my page_load event. I want to retrieve the text of the selection from the dropdownlist. I'm
using dropdownlist.selectedvalue.tostring(), which works on original page_load but not when I make another selection, even though autopostback is set to true. Do i have to write something in the selectedindexchanged event when not databinding?

I've many input elements one of which is, a radio button group with Autopostback set to true. After selecting one item from the radio button, the drop down list below fetches values from database and is refreshed. I choose some value in the dropdown list and submit the form. I've many server side validation controls. When I submit the form, if any of the server validation fails, it'll show the error message in the form. But the value I choose in the dropdown list disappears and it shows the first value of the dropdown list.
How to show the selected value in the list after submission of form?
Below is the partial code from my form. When I type anything other than "Hello" is the "Comments" text box, it will show the error message. I know I can use, other validators to check this. But purposely I want to use Customvalidator.

I have a dropdownlist that is not bound to a datasource, I have hard coded a few items in the list cause the list is always constant and will never grow and there are only 4 entries init. Anyway, after i load the page and make a selection from the dropdownlist and do a postback, the dropdown always returns to the default selection...which tells the users to make a selection.How do I get the dropdown to keep the selected value after the postback? I want to be able to display the selected value all through until another selection is made.
