How to programmatically build a template for datalist

Posted By:      Posted Date: September 05, 2010    Points: 0   Category :ASP.Net
 
Hi everyone.i want to write a page contain an datalist and several ObjectDataSource. The datalist will chose ObjectDataSource according to QuerryString passed to that page.My idea is like:switch (Request.QueryString["category"]){ case "car": DataList1.DataSource = CarDataSource; DataList1.DataBind(); break; case "aircraft": ...}PlaceHolder1.Controls.Add(DataList1); However, it doesn't work, I think it need to specify a template for that DataList. But those datasource has different table structure, how to build the template for DataList based on the table structure of datasource?Alternatively, i'm thinking to create several datalists bind to each datasource with static template, and post the right one to PlaceHolder. DataList1.ItemTemplate = new MyTemplate();private class MyTemplate : ITemplate{ //i dont know how code here} I searched and read http://msdn.microsoft.com/en-us/library/aa289501%28VS.71%29.aspx, but it makes me more confusedCan you provide a tutorial of writing template for a datalist?Thanks

RPC and C++: Build a Template Library for Distributed Objects Containing Multiple Interfaces

  

Building a C++ template library for developing distributed object-oriented applications using Remote Procedure Calls (RPC) allows the programmer to design RPC applications that are composed of components that implement multiple interfaces. This article demonstrates the use of techniques such as assembly-level thunks to build machine code on the fly, and C++ features such as templates, conversion operators, virtual destructors and virtual function tables. Along the way, familiar C++ interfaces and classes are transformed into a distributed application. The benefits of using distributed objects rather than raw remote procedures, which include writing fewer lines of code, is explained.

Workflow designer causes VS 2010 RTM to freeze when editing build process template.

  
I have a Dell Studio 1747 laptop with Intel i7 1.6GHz, 6GB RAM, Windows 7 Professional x64. I recently "updated" VS 2010 RC to RTM (removed all of RC and installed RTM). So far so good. Also, I have TFS 2010 RTM on the machine working perfectly, and have two team projects in there. Now, on a given solution, I copied DefaultTemplate.xaml to NewDefaultProcessTemplate.xaml and checked it in. I check it out and open it, and the workflow designer shows up. Then, I "Expand All" and go down to the "Compile, Test, and Associate Changesets and Work Items" section. If I click a subsection to collapse it, the mouse cursor changes to an hourglass and stays like that indefinitely. Sometimes, after a couple of minutes, the action is performed; then, it happens again up to a point where VS completely freezes. I have cleared VS 2010 cache, and have performed a repair on VS 2010 and TFS 2010 (just in case) to no avail. I have even disconnected from TFS right after openning the file, and still the same issue. This is f****** extremely frustrating. I can't do anything on the workflow designer. HELP !!!!!

Creating a dynamic site using custom template programmatically.

Programmatically activating an admin-approved form template to a site collection?

  

Hi,

I am currently programmatically generating infopath forms with code-behind, and for each generated form, I need to be able to host the form template as a content type. Since I have a farm solution, I know that I would usually have to publish manually to admin-approved form template as opposed to form libraries or content types directly and afterwards create content types which reference those form templates. I was wondering what I would need to do to achieve the following results:

1) Programmatically activate a form template to a site collection (this is the big question mark for me)

2) Programmatically generate a content type which references said form template (I believe I already have this part down using the SP Object Model)

The environment I am building in uses SharePoint 2010 Enterprise Edition, InfoPath2010, .NET 3.5, VS 2010.

Any assistance would be MUCH appreciated.

Send SQL Input file using Build Process Template

  

Hi. I think the title pretty explains the problem.

Is there any activities I can use to send my input script into a SQL server? (The script only contains INSERT INFO Header() VALUES () )

If not, could anyone give me any hints or directions to start on how to make SQL custom activity. (NOT how to create custom activity in general).

 

 

Thank you for any replies!

Use jQuery and ASP.NET AJAX to build a client side Repeater

  
By sending only data to the client, you can profoundly reduce the size of what you send and see a substantial increase in performance. You also allow yourself the ability to easily add features like light-weight sorting and paging on the client. This can not only improve your users' experience, but reduce server load and bandwidth requirements.
