I'm sorry i've Autopost Back true , Well i give you my code ddl line,
<p>
<label>
Insurance Provider</label>

<asp:DropDownList ID="DrpInsuranceProvider" CssClass="DropDownSlide" AutoPostBack="true" OnSelectedIndexChanged="DrpInsuranceProvider_SelectedIndexChanged" runat="server">

</p>

And aspx.cs code C# on event here
protected void DrpInsuranceProvider_SelectedIndexChanged(object sender, EventArgs e)
{
if (DrpInsuranceProvider.SelectedItem.Text != "Choose One")
{
txtothers.Enabled = false;
}

}

Solution 2

check you page load event.
It may be you have given some code that is responding to client.
If this is the case then your event will not work because its returning back from page_load

for css issue
when you apply disable to any control it adds a class named as "aspNetDisabled" you can view in source(ctrl+u).
If you will apply a class using jquery new class will override the existing style. Here on disable you are applying "aspNetDisabled" class.
To resolve this use style as CssClass="YourClass" and then apply "disable" using javascript not jquery.

Hope this helps!!!

Because of update panel this is not occuring as of my knowledge.
I face the same issue in my application there I find solution that I was applying style using class="Myclass" when i was disabling it. It gets overridden by AspnetDisabled class. Then I apply using CssClass="MyClass" It starts working. In your case already you are using CssClass="YourClass" can you send me some more information so that i can debug on my side also
Thanks

with update panel what are you using "scriptmanager" or "toolkitscriptmanager" ....
Try by changing among these

ShortProgrammer 25-Oct-13 8:14am

I'm using <asp:ScriptManager ID="ScriptManager1" runat="server">

C For Code!!! 25-Oct-13 8:19am

i said you can check it using both if you are already using script manager
check by using toolkitscript manager

Solution 3

it is happening because your are adding some attribute from server side code to DDL correct me if i am wrong.

if you are doing so please avoid that adding attribute and do it from ASPX page.
