Hi,
I downloaded trial version of Webdropdown version:11.2.20112.1019 and started using that in my application to see whether it functions properly. If it works well, I can go ahead to buy paid license for this control.
It has been around 45 days I downloaded the control and now I am able to see one issue suddenly.
When I use $find("webdropdowninstance"), it retrieves NULL.
Is it because the trial version might have expired or there is some other issue. Please let me know.
Hi, Sunil Mehta.
You can check this forum post, I think it will help you. If you have some other questions don't hesitate to ask them.
Best regards,
Nikolay
Hi Nikolay,
I have tried using ClientIDMode="Static" like this:
<ig:WebDropDown ID="dropdown" runat="server" ClientIDMode="Static">
</ig:WebDropDown>
After this, I tried using $find("dropdown") and also #find("<%=this.dropdown.clientID%>") but both are returing NULL value and not the object. What may be the issue?
Note: I am using ClientIDMode as "AutoID" in web.config file and I am not looking for a solution to make ClientIDMode changes in web.config.
I tested this and think your problem is because you are trying to access the control, at such state of the page live cycle, when the drop down is not created yet.
As far as you have ClientIDMode set to "AutoID" in the web.config, this means you cannot use "Static" value in your page. This also means that you will need again to access the element using server tags and using client id of the control. In JavaScript you need the following code:
<script type="text/javascript">
$(window).load(function(){
var dd = $find("<%=this.dropdown.ClientID %>");
});
</script>
As you see I'm trying to find the drop down, at stage that I know the control is already in the DOM. I'm using jQuery wrapper for the "window" object and attach to the "load" event - I hope this is not a problem for you. This problem may occur only when the page is loading, while if you attach to some of the WebDropDown client-side events the control will be already in the DOM.
One other note is that, ASP.NET client-side part of the control are added to the DOM, after the DOM itself is loaded. If I can use the jQuery term, this is after the following event is fired:
$(document).ready( );
That's why the best time to try to find ASP.NET control is after the browser window object is loaded.
So I hope this will help you to resolve your issue, if not this maybe means there is some problem with the version of the controls that you are using and we this will need further investigation.
I definitely feel that there is some problem with the version of webdropdown control that I am using. When I last downloaded the control and used in my application, $find was working fine. From last 15-20 days, $find is not working and I did not change anything in the code. My first thinking was that may be the trial version has expired now and that's why there may be some settings in the control which are not allowing it to be used now.
Please advice.
Also, Nikolay, Is it possible to access your controls using Document.GetElementbyID??
If it's not a problem for you, please create different forum thread for this issue. It's because the last problem is different from the title and idea of the current forum thread and it such cases is better to separate them.
Thank you
Is there a way to set the current display text and value of a webdropdown in the server-side(code behind vb file)?
Thanks,
Sunil Mehta.
