AsyncUpload Unable to Activate Dialog In WebBrowser Control

[Joe]

Hello, I am attempting to automate file upload using a third party site. The site is using AsyncUpload. I am able to manually click on the Telerik control to activate the Dialog. But unable to activate the Dialog using VB.Net and the WebBrowser control (See screen shot attachment).

Thank you very much for help!

3rd Party HTML Section:

<tr align="top"> 
    <td nowrap="nowrap" align="right"><font color="#ff0000">*</font> File:</td> 
    <td> 
    <div id="ctl00_ContentPlaceHolder1_SendFile" class="RadAsyncUpload RadUpload RadUpload_Default"> 
        <input id="ctl00_ContentPlaceHolder1_SendFile_ClientState" name="ctl00_ContentPlaceHolder1_SendFile_ClientState" type="hidden" /> 
    </div> 
    </td>
</tr>
<tr> 
    <td align="right" colspan="2"><input type="image" name="ctl00$ContentPlaceHolder1$ibSendBatchSubmit" id="ctl00_ContentPlaceHolder1_ibSendBatchSubmit" class="ibBatchSendSubmit" src="images/btn_send.gif" alt="Send Batch" style="border-width:0px;" /></td>
</tr>

vb.net logic:

WebBrowser.Document.GetElementById("ctl00_ContentPlaceHolder1_SendFile_ClientState").InvokeMember(

 

"click")

I also tried using the <div> ID "ctl00_ContentPlaceHolder1_SendFile" class without success

Hello Joe,

 
Unfortunately such behavior is not supported because of browser security limitations. hope this will explain the issue.

This is unfortunate indeed!

The similar dialog provided by the IE browser is allowing the click event to occur.

I don't see how allowing the click event is a security issue.

Hi,

 If I understood you right you are trying to upload files dynamically-this behavior is not supported with any input at all -you can only achieve is after a manual click over the upload control.

Hope this will explain the issue.

Kind regards,

Hi,

If simulation of click is not supported. Can I call the method which allows upload a file ?

[Plamen]

Hello,

Unfortunately no -both behaviors -click and calling the method are browser limitation- if you want to upload a file you need to click manually on the upload control.

Hope this will explain the issue.
