John,

Interesting results. Thanks for sharing.

The answer is simple. When cookies is turned off, the ISRes.axd is redirected to the login form, and hence it doesn't return the expected result/response.

To resolve this issue, simply exclude ISRes.axd from the authentication paths, which means ISRes.axd should always be loaded regardless of the authentication state.

The following example might do the trick:

<location path="ISRes.axd">
<system.web>
<authorization>
<allow users="*" />
</authorization>
</system.web>
</location>

When cookies is turned off, the session will likely changed every time because session used cookies to store its own internal ID.

The WebCombo dropdown arrow doesn't show means that its script is not loaded. So I'll likely there are server-side errors while the scripts are requested from the server. To investigate this issue, you need to use HttpWatch and then investigate the response of each script resource.

The response is likely to be a server-side error, if you manage to get the exact error message, please post it. 

John,

It's interesting to hear that the WebUI controls failed to work when you turned off the cookies.

Can you help to check this, try to turn off cookies then run your application. When you got all those errors, try to paste one of the ISRes request (eg, ISRes.axd?F/ISCore.js) in the browser's address directly. 

Please share what response you got in the browser. Thanks.

Dan,

Yes, you can see all text description through Localization Manager in WebGrid. See how to use Localization Manager here:http://support.intersoftpt.com/Docs/WebGrid/6.0.7200/Localization Manager.html

Alternatively, you can find the xml file in [Installed WebUI Studio Location]\CommonLibrary\WebGrid\v7_0_7200\Localization\Default.xml.

In fact, using Localization Manager, you can customize all textual content for your application globally (in case you wish to use the same text in the entire applications), so you don't need to customize the TextSettings to every Grid instances in all your pages. However, consider to use TextSettings if you need to customize the text for specific Grid instance.

When your Save function is called via the button, does it perform full postback or AJAX (FlyPostBack)?

The ClientAction will work only in FlyPostBack context. If your page is using full postback, try to use Page.RegisterClientScriptBlock and emit a javascript function to perform grid's Refresh method in the client side.

However, for better user experience, I think you may want to try using FlyPostBack mode (this can be easily achieved if you're using Intersoft WebButton control) to delete something in database then refresh the Grid without full page refresh.

Hope this helps.
