I had this issue where I wanted more than one row of headers in the TabContainer as I had a large number of panels and was not able to fit them in the page.

Here is the solution. [make sure you download the toolkit with source]

Open the AJAX Control Toolkit's solution by clicking on the solution file inside the toolkit folder.  

Open the file Tabs.css under AjaxControlToolkit/Tabs/Tabs.css

And make the following changes.

/* default layout */.ajax__tab_default .ajax__tab_header {}

.ajax__tab_default .ajax__tab_outer {display:-moz-inline-box;display:inline-block}

.ajax__tab_default .ajax__tab_inner {display:-moz-inline-box;display:inline-block}

.ajax__tab_default .ajax__tab_tab {margin-right:4px;overflow:hidden;text-align:center;cursor:pointer;display:-moz-inline-box;display:inline-block}

Now click on Build -> Build Solution to build the solution.

Use the AjaxControlToolkit.dll under ToolkitTests/Bin folder as your reference from now on.

Add this dll file as reference to your current website and you should have the 2 rows.

I have been going through the ASP.net forums and many people have had issues with GridViews especially the situation where the user wants to group each row by a particular condition.

There are controls available in the market which solve the issue (only sad part is we need to buy them).

I have used up 2 GridViews and AJAX Control Toolkit's accordion to achieve the required result. I have not done any back-end code, so this enables even a novice developer to create this page. Also I am using the NorthWind database provided by Microsoft.

The other day I was trying to install PHP and apache server on my Vista machine. As I went ahead it got a little bit complicated and some things didn't work out. Then had to search for stuff online and finally got hold of this article which works fine.

Installing Apache:

Uninstall any previous installations of Apache Web server (Start > Control Panel > Programs and Features).

Turn off your firewall (Control Panel).

Stop User Control Access(UAC). Do this by turning it off on your vista machine.

Get the most recent version of apache from http://httpd.apache.org/download.cgi and put it on your desktop. Rename it to apache.msi

Start > All Programs > Accessories

Right-Click “Command Prompt” and choose “Run as Administrator”

Manually remove directories containing previous apache installations (like C:\Program Files\Apache Software Foundation…)

Change to your desktop folder (At prompt type cd desktop)

Type “msiexec /i apache.msi” on the command prompt.

Run through the Apache installer. I’m running a development server, so I left the domain and computer name blank. Choose the default server on port 80 for all users option. Change the installation directory to c:\apache.

Reboot.

The little Apache feather won’t appear on the task bar under Vista with the present version of Apache (2.2.4). To remove the “error” box that says ‘the operation completed successfully” on startup, go to All Programs > Startup, and remove the Apache item there.
Browse to http://localhost. It should say “It works!” If it doesn’t, check your httpd.conf file by going to All Programs > Apache HTTP Server 2.2.x > Configure Apache Server > Test Configuration. Follow the directions for fixing the configuration file.
Turn your firewall and UAC back on.

Now you can install PHP the same way you did for apache. (Follow the same steps as you would do for Windows XP, just turn off the UAC).

I was trying to find a solution which did bulk updating for all the rows in a gridview, as the gridview provided by VS2005 had its usability issue (at least that's what I thought). After doing some googling I found a set of different grid views available at codeplex called 'ASP.NET Real World Controls'.

Its got a BulkEditGridView, FrozenGridView, GroupingGridView, InlineInsertGridView and TwoHeadedGridView. You can get a hold of the .dll file from http://www.codeplex.com/ASPNetRealWorldContr.
Here is an example of bulk edit grid view.

<cc1:BulkEditGridView ID="BulkEditGridView1" runat="server" AutoGenerateColumns="False"            

DataKeyNames="CategoryID" DataSourceID="AccessDataSource1" EnableInsert="False"            

InsertRowCount="1" SaveButtonID="Button1" AllowPaging="True" BackColor="LightGoldenrodYellow" BorderColor="Tan" BorderWidth="1px" CellPadding="2" ForeColor="Black" GridLines="None" Width="502px"><Columns>

<asp:BoundField ReadOnly="True" DataField="CategoryID" InsertVisible="False" SortExpression="CategoryID" HeaderText="CategoryID"></asp:BoundField>

<asp:BoundField DataField="CategoryName" SortExpression="CategoryName" HeaderText="CategoryName"></asp:BoundField>

<asp:BoundField DataField="Description" SortExpression="Description" HeaderText="Description"></asp:BoundField>

</Columns>            

<FooterStyle BackColor="Tan" />            

<SelectedRowStyle BackColor="DarkSlateBlue" ForeColor="GhostWhite" />            

<PagerStyle BackColor="PaleGoldenrod" ForeColor="DarkSlateBlue" HorizontalAlign="Center" />            

<HeaderStyle BackColor="Tan" Font-Bold="True" />            

<AlternatingRowStyle BackColor="PaleGoldenrod" /> </cc1:BulkEditGridView>        

<asp:AccessDataSource ID="AccessDataSource1" runat="server" DataFile="~/App_Data/Nwind.mdb"            

DeleteCommand="DELETE FROM [Categories] WHERE [CategoryID] = ?" InsertCommand="INSERT INTO [Categories] ([CategoryID], [CategoryName], [Description]) VALUES (?, ?, ?)"             SelectCommand="SELECT [CategoryID], [CategoryName], [Description] FROM [Categories]"            

UpdateCommand="UPDATE [Categories] SET [CategoryName] = ?, [Description] = ? WHERE [CategoryID] = ?">             <DeleteParameters>                 <asp:Parameter Name="CategoryID" Type="Int32" />             </DeleteParameters>            

<UpdateParameters>                 <asp:Parameter Name="CategoryName" Type="String" />                

<asp:Parameter Name="Description" Type="String" />                 <asp:Parameter Name="CategoryID" Type="Int32" />            

 </UpdateParameters>             <InsertParameters>                 <asp:Parameter Name="CategoryID" Type="Int32" />      

           <asp:Parameter Name="CategoryName" Type="String" />                 <asp:Parameter Name="Description" Type="String" />             </InsertParameters>         </asp:AccessDataSource>         <asp:Button ID="Button1" runat="server" Text="Update" Width="200px" />

You just need to make sure that you changed the SaveButtonID property to the button's ID.
