Remove Selected Value In Dropdownlist?

Feb 22, 2011

actually i want to delete the value from the dropdownlist once it is selected i.e after clicking submit button the value must get removed but the problem here is that in my dropdownlist only 1st item is getting selected and even after removing the value [through coding] [it shows that value is removed] the same item is getting selected again and again...here is the piece of my code...

protected void Button2_Click(object sender, EventArgs e)
{
String imid = DropDownList3.Text.ToString();
int imageid = Convert.ToInt32(imid);
String lid = DropDownList4.Text.ToString();

C# - Disable Or Enable 2nd Dropdownlist In Aspx Based On Selected Choice Of The 1st Dropdownlist Box

Apr 15, 2010

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>

MVC :: Dropdownlist Is Accepting "selected" But Isn't Rendering That Option As Selected

Sep 30, 2010

I thought this would be pretty simple, and in fact it's working on another dropdownlist on the same View, so I'm hoping I missed something very small that is easy to fix. Here's my code:

[Code]....

When I step through the code, the 'Active' option's 'Selected' property is being set to true. That's expected. But when the View renders, it's not selected and a look at the page source shows that the selected property isn't set. What is the problem here, and what's the solution?
