How to enable or disable asp.net DropDownList control using jquery when checking an asp.net checkbox.
So I have I have an asp.net checkbox when I check it I want to enable/disable a DropDownList.
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>
is there any Control or Jquery Plugin exist for asp.net Auto Complete DropDownList? link a sample here.I don't want use asp.net ajax control toolkit
View 1 RepliesI have a dropdown list for the which values are coming from DB. There is one option name OTHER, when I select other the textbox appears. For that Textbox I have made a required field validator. Till here it works fine. But when I select any other option, still it gives me validator errors. It should not happen. It should only give me required field error when the user doesn't fills the textbox on select of OTHER option. Please see the code.
Dropdown and Textbox code:-
<asp:DropDownList ID="ddlGraduation" runat="server" CssClass="txtfld-popup_drp"></asp:DropDownList>
<asp:RequiredFieldValidator CssClass="error_msg" ID="reqGraduation" runat="server" ControlToValidate="ddlGraduation"
ErrorMessage="Please select graduation details" InitialValue="--Select--" SetFocusOnError="true"></asp:RequiredFieldValidator>
<asp:TextBox ID="txtOther" runat="server" CssClass="txtfld-popup_p"></asp:TextBox>
<asp:RequiredFieldValidator ID="reqOther" runat="server" ControlToValidate="txtOther" ErrorMessage="Please specify your qualification"></asp:RequiredFieldValidator>
JS code for hiding and show the textbox when user select and deselect the OTHER option from dropdown list:-
<script language="javascript" type="text/javascript">
function pageLoad() {
$('#ctl00_ContentPlaceHolder1_txtOther').hide();
$('#ctl00_ContentPlaceHolder1_ddlGraduation').change(function () {
if ($(this).val() === "Other") {
[Code] .....
How to achieve this...

I have file upload and Radio button list controls in the page
Requirement:
When the page load, the file upload control has to be enable = false when I click on the radio button list's Yes option then it has to be enable = true and when No option is clicked then enable = false
Why when a control does contain value but it's set to .Enable=False that all controls become disable (that's ok) but why that the ViewState doesn't retain the data on the next post back? If I get the UserControl without modifing its Enable state, the ViewState work between post back.
How can we disable a UserControl that all its control become disable (this part work) but all of them KEEP use the ViewState (this doesn't work)?
Clarification:
1)In the aspx.cs click button EDIT:
myControl.Enabled = false;
//This produce to have all controls in myControl to be disabled.
2)In the asp.cs: click Save to leave the EDIT state:
myControl.Enabled = true;
//This produce that all controls inside myControl are blank : no viewstate!
Other postback works because we do not put myControl.Enable to false.
