An error occurred while communicating with the remote host. The error code is 0x800703E3.

Hi:
I have a page that is way too big, but it is what it is.  It has 6 tabs (TabStrips), and each tab has a grid (Radgrid).  In one of the grids (which is contained in a user control ascx) clicking on the edit launches a RadWindow, where the user can add or change data.  On save the grid is rebound.  Both the base page and the ascx has a RadWindowManager in them.  The base page RadWindowManager has an OnClientClose="refreshGrid" client side event.  In production (yeah only production), I am getting the following IIS error:
    An error occurred while communicating with the remote host. The error code is 0x800703E3.
when the user closes and saves on the RadWindow.  Production is an IIS 7 environment.
Any suggestions?
Phil

Hi Phil,

You are the first to report such problem and at this point I cannot tell what the reason for the error is. Could you please provide more information? What happens if you call the refreshGrid() function manually (e.g. by clickin on a <button onclick="refreshGrid(); return false;">test</button>)? Also, what happens if you execute the code in that function with a small timeout?

All the best,

Hi:
The error occurs in production, not on my development server.
In development, I added the following link-button:

<asp:LinkButton ID="refreshLinkButton" runat="server" OnClientClick="refreshGrid()">Refresh</asp:LinkButton>

I launched the form, added some data via SQL Management Studio and clicked the Refresh link-button and the new row appeared.  I have remove the button now that I have tested that.

I have added CDATA to my javascript as follows:

<script type="text/javascript">
//<![CDATA[
...
//]]>
</script>

and I have added in the javascript code a setTimeout for .1 of a second.  I need to get the setTimeout rolled into production.

Hello Phil,

In such case, could you provide a live Url to a page where the problem can be reproduced? We will check it right away.

Hi Phil,

I don't see Telerik mentioned in the stack trace, so I cannot tell if the problem is directly related to our controls or not. A quick search in Google shows that the error usually happens because the client disconnects in a middle of a request. Please check the search results and try the suggestions provided in the sites found by Google.

Greetings,

Hi:
It seem that something in the design pattern taken from your example code for RadWindow closing and evoking a postback in the calling page to reload the RadGrid, causes a rapid firing of javascript.  IIS7 does not like the rapid firing of javascript.  You guys seem to be the King of javascript client side code, so I was surprised not to find any postings of the issue.

Hello Phil,

Well, as I said, you were the first to report such problem and so far, I am basically guessing what might be wrong :)
Could you please post the exact steps (in code) that cause the problem? e.g. something like:

1. a button in the content page is clicked and calls this serverside / client-side function
2. the next step fires this code
3. the last step causes the resulting error.

This might help me provide you with better suggestion.
What I can say for now is that I assume you are referring to this demo. In it, once the button in the content page is clicked, we execute a server-side function at the end of which, we output JavaScript code that fires the following function:

function CloseAndRebind(args) {
    GetRadWindow().BrowserWindow.refreshGrid(args);
    GetRadWindow().close();
}

What this function does is to fire a function (refreshGrid()) in the context of the parent page and to close the RadWindow after that. This logic is not causing any problems in our demos and in IIS, so I assume that in your case, there is something else. What I would suggest (again "a shot in the dark" I'm afraid) is to change the logic a bit and if you use that RadWindow only to update a record in the grid - to call the refreshGrid() function directly from the parent page when the RadWindow is closed.
To do that, you can use the OnClientClose property and set there the name of the function you wish to fire once the RadWindow is closed.
e.g.
OnClientClose="refreshGrid"
