Prevent Multiple Submissions of Forms in Asp.Net

Here is the issue. You have a form and someone double clicks the Submit button, and curiously enough you have two forms that were submitted!  My first thought was to disable the button on click with javascript, and then when the page loaded again the button would be enabled, but that was a no go.  Asp.Net does not fire events for disabled buttons.

Went looking around and found a page that suggests using a variable to check to see if it was submitted or not in javascript.  As far as I can tell this is the best way of preventing this issue.  If they have javascript disabled however then it might be a problem though, but I am not even going to worry about those < 1% individuals.

I changed their javascript function to not use the .Net markup inside the javascript to get the clientID.  I prefer making the ClientIDMode="Static" and having just pure javascript in the function.

 var isSubmitted = false;
    function preventMultipleSubmissions() {
        if (!isSubmitted) {
            $('#btnSaveRecord').val('Submitting');
            isSubmitted = true;
            return true;
        }
        else {
            return false;
        }
    }

      <asp:Button ID="btnSaveRecord" class="btn btn-default" runat="server" Text="Add" OnClick="btnSaveRecord_Click"  ClientIDMode="Static"  OnClientClick="return preventMultipleSubmissions()"/>

Asp.net Publishing Broke Site - "App_WebReferences is not allowed because the application is precompiled"

When publishing site to live, trying to go to site gives a Server Error – Runtime Error.  Looking in the Application logs on the server  gave " The directory App_WebReferences/ is not allowed because the application is precompiled."   This was causing a bit of stress to a programmer in a our company since he tried to publish a change during business ours.   Solution http://stackoverflow.com/questions/9892646/how-publish-my-web-site When publishing the options that work are to have “Delete all existing files prior to publish”, and “Precompile during publishing” checked.  And “Exclude files from the App_Data” unchecked.

Telerik - Custom Group Footers In RadGrid

As anyone that has dealt with this knows Telerik only supports a single Group or Header Template.  So what happens when you want to change them?  You really only have two options from what I have seen.  The first option is to have something in the data that is brought back that you can use in the designer code in the form of a conditional.  Too bad I do not see a way to check the data based on level like some sort of ParentID like some people have done.  If the ParentID is null  It would look something like below where you check it in the designer: < asp : Label runat = "server" ID = "Label2" Text = '<%# "Number of items in group: "+ (((GridGroupHeaderItem)Container).AggregatesValues["AvailableUnits"]) %>' Visible = '<%# ((((GridGroupHeaderItem)Container).AggregatesValues["AvailableUnits"]) != null)%>' > Or you can use the code behind to really get at the groupIDs like this per
