Dec 14, 2010

The values in one of the fields in my GridView's table are just either a zero or a one or a null. Well, "zero," "one," and "" are not very appropriate values to display to the end user. Is there a way I could change these to "True"/"False"/"NA" or "Yes"/"No"/"NA"?

C# - Change Rendering Order Of Controls?

Mar 2, 2010

I found this article on how to manipulate the rendering sequence of asp.net controls.: [URL]I placed some placeholders on the page to encapsulate the controls i want to move around. The problem is, that RenderChildren does render the controls without the html i placed into the placeholder like this:

<asp:PlaceHolder id="phOneToMove" Runat="server" Visible="true">
<tr>
<td><asp:Literal id="label1" Runat="server">Caption</asp:Literal></td>
<td>
<asp:TextBox ID="textbox1" runat="server"></asp:TextBox>
</td>
<td>
<asp:RequiredFieldValidator ID="validator1" Enabled="true" ControlToValidate="textbox1" runat="server" EnableClientScript="False" ErrorMessage="error"></asp:RequiredFieldValidator>
</td>
</tr>
</asp:PlaceHolder>

The controls are rendered without the tr and td around.How can I handle this? All I want is to change the order of the placeholders like in this example phOneToMove.

MVC :: Change Sort Order Of Relationship?

Feb 10, 2010

I have 2 tables with a relationship by EmployeeID (Employee, Cases)

The relationship name is Purchases (ie employee->Purchases), and iterating through it gives each row in order by date (entry order perhaps?).

There could be thousands of rows, so I want to present this collection in reverse date order.

Would I have to define a provider or repository to call instead of just Employee->Purchases?

Change The Default Document Order Programmatically In IIS Using C#?

Jan 18, 2010

I have an ASP.NET website application, and there is a home page for my web site. I need to be able to change the default document of my website programmatically (C#) so that I can make another web page take priority above the one that already exists. I would then like to revert back to the previous default document order.

Example :

I have two home pages - Home1.aspx and Home2.aspx. In the IIS default document settings I have added the two pages and made Home1.aspx be the first default document then Home2.aspx the second. I need in some cases to be able to change the order of the two default documents so that Home2.aspx is the first default document then Home1.aspx the second.

How can I do that from my C# code?
