File input field always null

[Sameer]

Hi telerik,

I am trying to access the file input in javascript onfileselected event but it is always returning a null value. args.getFileinputfield() What is the correct way to access the input field?

Thanks,
Sameer

Hi Sameer,

You have to set DisablePlugins="true" property of RadAsyncUpload and add the following style.

CSS:

<style type="text/css">
    #thumbnail img
    {
        filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(sizingMethod=scale);
    }
</style>

Thanks,
Shinu.

Shinu. I want to retrieve the file extension in the onclientfileselected event. There I am getting the file name but no way to get the extension. Any suggestion?

Hi Sameer,

You can try the JavaScript split() to extract the extension from the file name. Please have a look into the following JavaScript code i tried which works fine as expected.

JavaScript:

<script type="text/javascript">
    function OnClientFileSelected(sender, args) {
        //splitting the filename and hence extracting its extension with JavaScript split method
        alert(args.get_fileName().split('.').pop());
    }
</script>

Thanks,
Shinu.
