Microsoft Velocity provides distributed in-memory web application caching. This provides highly scalable, high-performance application caching. “Velocity Caching” can be used to cache any Common Language Runtime (CLR is the Virtual Machine of Microsoft’s .NET initiative) through simple API’s. From a general standpoint, Velocity was created with the goal of providing performance, scalability and availability.
The main application for providing scalable, available, high-performance applications using Velocity is by fusing the memory between multiple computers to give a single/unified cache view for the application to employ.The application can they store any CLR object that is serializable.

I recently wasn getting the following error when trying to call a webservice from javascript.
I was able to invoke the web services from the test page offered by visual studio, but accessing it outside the invoke method on the test page would not work.
By default, webservices protocols are not added to the webconfig. To access normal get/post services you will need to add the following in the <system.web> node.
[codesyntax lang=”xml”]
<webServices>
<protocols>
<add name=”HttpPost”/>
<add name=”HttpGet”/>
</protocols>
</webServices>

Here is a trick one, because IntelliSense doesn’t bring up the “SelectedValue” property for a RadioButtonList, or a DropDownList in an EditItemTemplate for GridViews you may forget that “SelectedValue” is an actual property of these controls.
Here is how you can set the selected value of a RadioButtonList inside an EditItemTemplate
[codesyntax lang=”html4strict”]
<asp:TemplateField HeaderText="Payment">
<ItemTemplate>
<asp:Label ID="lablePayment" runat="server" Text='<%#Eval("PayName")%>' />
</ItemTemplate>
<EditItemTemplate>
<asp:RadioButtonList Runat = "server" ID="rblPaymentType" SelectedValue='<%#Eval("PayTypeID")%>'>
<asp:ListItem Text="Check" Value="1"></asp:ListItem>
<asp:ListItem Text="Credit Card" Value="2"></asp:ListItem>
</asp:RadioButtonList>
</EditItemTemplate>
</asp:TemplateField>

There was a great post here by Yoann. B that provided a great example in C# for highlighting RequireFieldValidators: http://blog.sb2.fr/post/2008/12/12/Custom-TextBox-Required-Field-Validator.aspx
I expanded the code to allow for border widths, and converted the code to VB.

Here is the usage of the Overload.
You must register the custom control on the page, include the “Assembly” attribute if from outside your project.
[codesyntax lang=”vbnet”]
<%@ Register TagPrefix="MyCtrl" Namespace="Validators" %>
[/codesyntax]
The control is used just like the regular required field validator.
[codesyntax lang=”vbnet”]
<myctrl:textboxrequiredfieldvalidator ID="valid1" runat="server" ControlToValidate="TextBox1" ErrorBackgroundColor="Red" ErrorBorderColor="Red" ErrorBorderWidth="2" SetFocusOnError="true"></myctrl:textboxrequiredfieldvalidator>
[/codesyntax]
