I have a dataset with several tableAdapters in it. For some reason, one of them that I created doesn't show up when I try to put it into my objDataSource?
I can access and use it from codebehind (testing purposes for this post.

View 1 RepliesI 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:

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

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?

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.

I have this as the code behind right now when you press the button.. what other parameter settings am i missing and is this the right order to populate them for the source to acknowledge my values?

I am using Asp.net 3.5, C#, Visual Studio 2008. Ok, so I admit I am being really lazy here, but I know there's got to be a way to do this.
I have 2 identical listviews - listview1 and listview2. There is a checkbox in column 1 of both listviews, and a button on the page.
I would like to copy the rows that are checked in listview1 to listview2 when the button is pressed.
I know how to do this by looping thru listview1, but how can I do it in one step using an ObjectDataSource?
I am using visual studio 2008, i included a class in the AppCode folder and wated to use its functions in ObjectDataSource.

I have set the objectdatasource in the web form. Does I need to check anything as I find that method "objProductSuppliment_Inserted" does not run??

I've created a query in the table adapter for retrieving customer name based on the first letter. The query is executed fine, and the output is the customer name and ID. A Customer BLL accesses this query, and sends the results to an objectdatasource. This control is configured to use this customer-by-letter query. However for some reason, this objectdatasource does not bind the name and ID, but instead all the other fields produced by the main query in the table adapter (i.e. name, address, phone, etc....).
I'm probably not configuring something correctly, but I'm not sure what.
The BLL code:

I'm creating an ASP.net website with 3 layers (Presentation, BLL and DAL).
BLL and DAL are 'class library'. DAL has a typed dataset. Presentation refers BLL and BLL refers DAL.
I wanna populate my GridViews with ObjectDataSource, but it only shows me the DAL. Nothing from BLL...
What am I doing wrong?
Consider a fairly complex business object. For the sake of discussion, let's think about a "ClassRoom" object - that will have some attributes which occur once, such as "capacity" and "area". It will also have some repeating attributes - perhaps "desks" which will itself be a collection of desk objects. The desk object will in turn have attributes such as "width" and "height".My example is more complex, but that should show where I am coming from. The business object, as you would expect, exposes methods to get the attributes in and out. There is also logic included to perform the underlying database updates. Of course, the necessary business validation is also in there.
In terms of binding to the ASP page, I will need to bind the attributes of "ClassRoom" to a set of fields on the page (using one method on the object). I will also want to bind the desks collection to a Repeater or GridView (using another method on the object).Presumably, I need to find a way to use a single instance of the ObjectDataSource so that the updates to the two (or more) disparate sets of data can be kept in step. I suspect that if I simply put two data sources on the page, I will get two instances and therefore no correlation between them.This can't be a unique problem, but I'm struggling to find any useful information.
I was woundering if its possible for me to check for accesslevel value from the database using objectdatasouce.... From my coldfusion experience... i could just use an "if statement"
e.g: <cfif> (datasouce.column = x) then
<cfoutput> msg</cfoutput>
</cfif>
Am not so sure about .net.... All i am trying to do is to check for one value on the db and i dont mind puting it on code behind... i just need a way..

I have an objectDataSource which uses my stored procedure GetNotifications
And my GridView is bound to that objectDataSource
the only problem is that my stored procedure requires the variable @UserName and then returns the values for that username, but I do not know how to pass the variable to the objectDataSource, does anyone know the code for this?
I can get userName from HttpContext.Current.User.Identity.Name but how do I pass that to the objectDataSource?
I have a gridview bounded to an objectdatasource.
I want to get total count of record when there is paging = true or false in gridview.
I followd Brian Orrell LINQ tutorial for paging/sorting and created a gridview bound to an ObjectDataSource through a method call which gets data from adatabase. My form includes two buttons with a textbox next to each one of them. I need to be able to populatte th egridview depending on the button that was pressed, I cannot figure out how signal my method which button was pressed.

View 4 RepliesI 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?

I am trying to update record in GridView. But ObjectDataSource is creating original_{0} and new vlaue object (exactly the same).ObjectDataSource.UpdateMethod is as follows
[Code]....
The paremeters ("original_ProductBO" and "productBO") in the above function are supposed to have different values since I am editing record in GridView and then updating it.I have the checked the query by hard coding parameter values and it works. In the ObjectDataSource_Updating(..) event, I cheked the parameters ("original_ProductBO" and "productBO") , I am getting the same values. Can anyone tell why tow parameters have the same values when I am editing record in GridView Code for the ObjectDataSourec and GridView is attached below
