  • Case Study: M and M Software

    Family_Cabinet1

    Check out this case study from M and M Software which shows a cool web interface built using the same DevExpress ASP.NET controls that are available to you.

    Web-based Filing Cabinet

    M and M Software's new web app, "My Private Filing Cabinet" let's users get rid of their old filing cabinets and store important data online. They used DX controls to make it fast, feature rich and give it a professional designer look.

    This web based application provides features so the users can get rid of their old fashioned filing cabinets. It's called the 'My Private Filing Cabinet' website and it allows you to record and maintain your important information in one comprehensive location.

    Benefits Of Choosing DevExpress

    Click the image to get a closer look and you'll notice the website was built with DevExpress ASP.NET controls. Adding DevExpress controls to their app gave M and M advantages like:

    Superior User Interface

    "We've seen it all during our rigorous search for superior user interface controls and there is nothing better than the Developer Express suite of .NET components" – Gregg Mercede, M and M Software

    Time To Market

    "We began writing our own calendar components until we discovered DevExpress. It is as easy to use as Outlook and more importantly it's on the web. The tons of events DevExpress delivers with their components automates so much code than other companies we have investigated. DevExpress Suite has saved us hundreds of man hours in development." – Gregg Mercede, M and M Software

  • Download Hotfix for Visual Studio 2008 Property Serialization Issue

    Download KB967253 Hotfix Download and install this latest Microsoft hotfix which corrects the dreaded 'property serialization issue'.

    First The Solution

    Click here to download the 6mb Hotfix KB967253. A single (exe) file which updates your Visual Studio 2008 instance.

    The Issue

    Changes made in Visual Studio designer were not saved when going to the source view. The issue was first found with DevExpress ASP.NET controls. However, after further inspection, we found that this was a general bug with Visual Studio 2008.

    You can see the bug by following these 5 steps:

    1. Create a new web site
    2. Put a standard Wizard control
    3. Put a standard GridView inside the wizard's editable region (framed area)
    4. Go to the GridView's properties and set the PagerSettings.Visible to False
    5. Switch to Source view

    What do you see? If the changes are not serialized then grab the hotfix.

    You can read more about the original issue I reported on Microsoft Connect. The KB967253 hotfix addresses 7 issues in all and you can read about them on the Visual Web Developer Team blog.

    Thanks Microsoft

    Special thanks goes to Microsoft Developer Extraordinaire, Mikhail Arkhipov, for fixing these issues in both Visual Studio 2008 and Visual Studio 2010.

  • ASP.NET Grid Tip: How To Check For Empty Values In Header Filter

    Here’s a quick and useful tip for finding empty values when using the ASPxGridView’s header filter. For example, if you have a Date column:

    ASPxGridView Header Filter

    And you want to find all the Orders which have an ‘Empty’ ShippedDate value, then follow these 2 simple steps:

    1. Override the ASPxGridView’s HeaderFilterFillItems event
    2. Add the following 2 lines of code:

     

    C# Version:

    protected void ASPxGridView1_HeaderFilterFillItems(object sender, DevExpress.Web.ASPxGridView.ASPxGridViewHeaderFilterEventArgs e)
    {
      e.Values.Insert(1, new FilterValue("Empty", "", "[" + e.Column.FieldName + "] Is Null"));
      e.Values.Insert(2, new FilterValue("Not Empty", "", "[" + e.Column.FieldName + "] Is Not Null"));
    }

     

    VB.NET Version:

      Protected Sub ASPxGridView1_HeaderFilterFillItems(ByVal sender As Object, ByVal e As DevExpress.Web.ASPxGridView.ASPxGridViewHeaderFilterEventArgs) Handles ASPxGridView1.HeaderFilterFillItems
        e.Values.Insert(1, New FilterValue("Empty", "", "[" & e.Column.FieldName & "] Is Null"))
        e.Values.Insert(2, New FilterValue("Non Empty", "", "[" & e.Column.FieldName & "] Is Not Null"))
      End Sub
    

    This code create 2 new filter values for ‘Empty’ and ‘Not Empty’ which check if the field value is null:

    ASPxGridView Header Filter With Empty Filter Option

    Custom Filter

    By using this event, you can also create custom filters which:

    • Check if a certain field value is greater 50
    • Choose which columns to add the custom filters
    • And more…

    How? Check out the FilterValue Constructor help topic.

    Sample Project

    Here’s the sample project which contains both C# and VB.NET versions of the code. Click here to download: [GridCustomHeaderFilter.zip]

    Then drop me a line here and let me know what you think of this tip. Smile
