objectdatasource

问题 My error: ObjectDataSource 'dsGenre' could not find a non-generic method 'GetGenre' that has no parameters. My code: <asp:DropDownList runat="server" ID="genreList" style="float:left;" DataSourceID="dsGenre" DataTextField="Author_Name" DataValueField="title_id" /> <asp:ObjectDataSource runat="server" ID="dsGenre" SelectMethod="GetGenre" TypeName="libros" /> <asp:SqlDataSource runat="server" ID="sqlGenres" ConnectionString="<%$ ConnectionStrings:library %>" ProviderName="<%$ ConnectionStrings

问题 I have an object datasource that looks like this: <asp:ObjectDataSource ID="obdsList" runat="server" EnablePaging="True" SelectCountMethod="GetCountByID" SortParameterName="sortExpression" OldValuesParameterFormatString="original_{0}" SelectMethod="GetByID" TypeName="Services.Users" onselected="obdsList_Selected"> <SelectParameters> <asp:QueryStringParameter Name="ID" QueryStringField="ID" Type="Int32" /> </SelectParameters> </asp:ObjectDataSource> And a onselected event like this: protected

问题 In the "Report Data"..."New Dataset" dialog, I only have about 5 classes. None of my main business classes are showing up. Some that do show up don't show and properties. Some that show up are generic and there is not much point even showing these. e.g. SortedListBase<T> : SortedKeyedCollection<int, T> where T : IdEntity with two public static methods: public static SortedListBase<T> Build(string StoredProc, CTorDelegate CTorDelegate, Action<SqlCommand> AddParameters) public static

问题 I am using an SPGridView to present some data, and have enabled the filtering ability which works very well. Until you choose a particular item in the data to filter on...

Obviously the data is not automatically made safe... The data is in a datatable, and the SPGridView is fed

问题 I have an ASP.NET application and on one page there is a gridview that uses an ObjectDataSource to call a method that is located in another class named "Device". Well this class returns a speciala datatable. This is working. Now I need a method for updating data and for this I cannot use the class Device, so I would like to use the "RowUpdating" method of that grid from the code behind. I even wrote the code for this method and it is working and the method fires, if the user clicks the

问题 Using VS2012, latest SP/update applied. I have been very frustrated trying to get an ObjectDataSource to work. See http://bit.ly/XTpdvN and http://bit.ly/XTpsHi. I started a new Web Application project, compiling and running after each step, trying to make the steps as granular as possible. 1) Create new empty web application. 2) Add WebForm1.aspx. 3) Clean, rebuild, run (either View in Browser or in debugger). 4) Add new class to App_Code. 5) Repeat #3. 5) Add existing .mdf to App_Data. 6)

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form.

However I have an error in getPatientFullDetailsbyPPS The parameterized query '(@PPS nvarchar(4000))Select * from Patients where PPS = @PPS' expects the parameter '@PPS', which was not supplied. C#: public static Patient GetPatientFullDetailsByPPS(string PPS) { Patient

问题 I am using a Session Parameter on an ObjectDataSource. It works fine on the local development machine but I get this error after copying the website to the production server: Type 'System.Web.UI.WebControls.SessionParameter' does not have a public property named 'DbType'. 回答1: Me again! First Answer I gave was WRONG!
