DataSource Controls :: Binding An ObjectDataSource To A Property In Aspx Code, Not Code-behind

Dec 3, 2010

I want to bind an ObjectDataSource to a property in my asp page and I want to do it in the page's aspx code, not in code-behind. I've already done it in code-behind, as follows:

[Code]....

I'd prefer to get rid of the ugly code-behind and just do this in mark-up. Something like
[Code]....

This gives me a run-time error: Cannot create an object of type 'System.Object' from its string representation 'SelectedBook' for the 'DataSource' property.Is there a way of doing this declaratively and not in code-behind? Further, what if what I want is to actually use a child property of the property in question? For example, if my Book object has a ReaderComments collection, can I databind to it decaratively in the aspx mark-up?

DataSource Controls :: Enabling Paging On ObjectDataSource That Is Built Dynamically In Code Behind?

Oct 28, 2010

I have the following on my aspx page

[Code]....

Then in my code behind i have the following set up in 4+ button events, since each button serves a different purpose.. Prior to this past week, i was only working with 2 gridviews on the page.. that were linked to this datasource.. so everything was fine.. but recently had to add a Datalist to display the results a certain way.. I got it all working, but now that more records are in the table the datalist is growing in length on the page and cant figure out how to modify the current code to enable paging without having to redesign the logic all together to get it enabled.

Based on what i have below and above, is there a solution i can implement to implement paging ONLY for the Datalist? Or if it cant be specific, if enabled, will it affect the gridview that is already configured to enable paging, which already works?

I have a page where you can search and display other data, very simple layout. 1 Gridview and 1 objectdatasource. But i have 4 possible buttons that can populate the gridview..

i would like to control my objectdatasource from the code behind based on the button you click.

here is what i have right now.. but if possible, can this source not be hardcoded like this and only built in the code behind?

[Code]....

I found this site with a solution to this persons issue, but i cant seem to get mine working this way.

DataSource Controls :: ObjectDataSource Binding To Querystring When Don't Want It To?

Sep 23, 2010

I have an ODS control populating a Telerik grid. The ODS definition is pretty simple. It's set to call a method on a static class that has one parameter (entityID). I set this parameter in the OnSelecting event. When I test this, the world is a happy place and all is fine.

Then, I pass a query string to the page (which sets various unrelated values for the page, we'll say parameters X and Y). The page call's Telerik's radgrid.Rebind() event. When this happens, an error is throw from the ODS saying that the underlying method (the static data procedure) does not support parameters X and Y.

So, why is ODS thinking it should be using any querystring values at all when I have explicitly set the entityID parameter (of type Asp:Parameter)? How do I stop this from happening?

The Html:

[Code]....

The OnSelecting:

[Code]....

I see this odsList_OnSelecting being hit and the inspection of e.InputParameters only contains my expected single entry.

DataSource Controls :: The Type Specified In The TypeName Property Of ObjectDataSource Not Found

Jun 26, 2010

I am using Visual Studio 2010 for the first time. I program in MS Access for a long time at decide to move to the ASP world. My problem is that I design my first web .aspx default page with a simple data grid. I decided to connect the data via the business object data adapter. I use the Dataset designer to great the dataset. All looks well and works fine on my PC. But when moved to the server I get the Terror "The type specified in the TypeName property of ObjectDataSource not found".

From my reading for the past two days, it seems that something need to be define (a class of some sort) to let ASP know where to find the data adapter. If this is the case, then why did not Visual Studio 2010 did not automatically build the class in the appropriate BIN/ APP_CODE or Global directory and more importantly, why would it work fine on the PC , but not on the server. I am totally blind-sided by Visual Studio 2010 allowing me to design and test on PC but throws me a curl ball with moving to a server. Am I assuming to much from Visual Studio 2010???

What is the solution.. What I am looking for is to know where exactly where and how to write this class. I am so new to ASP, all of my reading just confusing me more and more by reading so many post on this error. I know it is probably a simple class to write somewhere, but why did not Visual Studio 2010 write it accordingly.

C# - Some Aspx Controls Are Not Recognized In The Code-behind Files

Jul 19, 2010

I noticed that some aspx controls were not being recognized by intellisense, and when I tried to compile, I got errors stating that the controls basically didn't exist.

After a lot of tinkering, I realized that the .aspx.designer.cs file was missing for several .aspx files.

What is the best way to re-create the files?

Changing The View (.aspx) From The Code-behind (.aspx.cs) Class?

Nov 1, 2010

I have a 'classic' ASP.NET app (.NET 3.5) with a pretty standard runat="server" style form with server-side controls and an 'Execute' asp:button. In the code-behind, the executeButton_click handler processes some of the other controls, runs a report, and drops the result into an asp:label. So the effect of pressing the Execute button is that the entire page reloads with the report inserted into the label.

I need to change this so that when the Execute button is pressed, the report pops up in a new window with a different layout (ie without the controls and form). If I was doing this in an MVC framework I would just change the view template in the 'execute' action, so the analogue for ASP.NET would be change the code in front, ie the .aspx file that gets used, from the code-behind class.

Is this possible? I know the link between the .aspx and the .aspx.cs isn't extremely tight as it is possible to reuse a code-behind class in multiple .aspx files. So can I set the .aspx file to render from the code-behind?
