I would change the filterexpression depending to the choice of some DropDownList but, i've tryed with ObjectDataSource_Filtering event but it seems that non reevaluate the filter.is it the right event?i've to do any other operations after changing the filterexpression?
View 1 RepliesI was wondering if I could use something like :
ObjectDataSource1.FilterExpression = " (ID in (Select ID from TablewithIDs where User = '{0}')) "
I am getting this error:
Syntax error: Missing operand after 'ID' operator.
how to use FilterExpression with an object datasource when it is bound using a selectmethod that returns a list of entity objects?
I get the following error when I attempt it.
The data source 'testODS' only supports filtering when the SelectMethod returns a DataSet or a DataTable
I have the following on my aspx page

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've been using the FilterExpression for the building of my GridView. I've built with this ability before, normally for searching for the name of an individual. However, the new project I'm working on has a small problem. I'm using an AND statement to filter the name via textbox and I'm also checking if the form was completely finished and if the form is reviewed via radio buttons.
Below is the code, but the problem is this. If any of the fields are blank (text field is left blank or the "both" is selected from the radio buttons) the form doesn't process my filter.
Is there an easy way to apply all three filters in a mix and match fashion (like no name, completed, not reviewed or any combination thereof)?

I get the Erorr: Input String was NOT a correct format.
The first three controlparameters are STRINGS and they work fine.
However the last two populate the controlparameter from text boxes that can only accept numbers and decimal point.
First the text boxes for {3} and {4} string parameters in the SQL filterexpression:
[Code]....
And then the SQLDatasource control parameters[Code]....
The last two control parameters are the ones is question as they feed {3} and {4} parameters in the filter expression, NOTICE how I set the type="double".The data input is expected to be like 152.25 or 3.6 or 4 etc,So why am I getting this error: [Code]....
I am using SqlDataSource control to query my data via store procedure. Based on which option the user picked from the RadioButtonList control, I want to dynamically at run time to choose which store procedure gets executed. How do I do this? I am already using Query String for my parapmeters. I can could use this for the store procedure as well. The problem is, how do I get the SelectCommand to pick the store procedure name from the parameter passed in the URL?
View 7 RepliesI have a simple web form with a dropdownlist and a ReportViewer. I would like to dynamically change the report within the viewer when the user makes a selection in the dropdownlist. I think I need to alter the ObjectDataSource that the ReportViewer is using. I've tried a few things without success.

i am building my objectdatasource dynmically when certain buttons are clicked on the page.. and with that the gridview is being displayed with the results of the objectdatasource that was built.

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.

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?
