IIF Evaluates Both Cases

Forgot about this little wtf with IIF() in vb.net.  It will evaluate both cases.  Another reason why I like c# better than vb.net. The following snippet will throw an "Invalid Cast Exception cannot convert DbNull to String" when the value of that cell is DbNull.  Even though you would think it would just return Nothing in that case.

                sIncident.ExpireDate = IIf(row.Cells("colExpireDate").Value Is DBNull.Value, Nothing, DateTime.Parse(row.Cells("colExpireDate").Value))

So an alternative is just to use If ..else

 If (row.Cells("colExpireDate").Value Is DBNull.Value) Then
                    sIncident.ExpireDate = Nothing
                Else
                    sIncident.ExpireDate = DateTime.Parse(row.Cells("colExpireDate").Value)
                End If

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

Bootstrap Modal Popup is Grayed Out

The popup shows up, but after it pops up the whole page becomes unusable.  So not only was it not displaying right, the whole page is frozen.  I found a StackOverflow post, below describing how the popup may have that behavior when it is nested inside elements that have positioning elements, which fits with previous experiences I have had.  One of the answers described how appending the modal popup to the body of the page  "$('#mytModal').appendTo('body');" would be a way of getting it out of any positioning elements.  Previously on a different page I had moved it out of some divs and it worked right.  However in this particular site the modal is in a ASP.Net site as a user control where the "offending" positioning element is in the master page and it contains the user control.  I stuck the script in the user control, but the behavior was the same.  When I used Firebug I saw that I was getting a "$ is not defined" message. With Jquery we ne
