You're in the
asp.net datagrid control
group:Could not find a property named in ASP.NET 2.0
asp.net datagrid control:
I get this exepction "Could not find a property named 'COM_NAME' on the type specified by the DataObjectTypeName property in ObjectDataSource 'ObjectDataSource1'." when i try to update a detailgrid or form. The detail grid is bound to an objectdatasource control
Hi,
Based on the error message, are you updating an ObjectDataSource object to tthe data source? is there a property named 'COM_NAME' in the object? Are you doing some COM interop in your code? Kevin Yu ======= "This posting is provided "AS IS" with no warranties, and confers no rights."
Hi Kevin,
The objectdatasource is indeed updating the database. There is a COM_NAME field(I have it also on other objectdatasource's) The object datasource is calling a webservice proxy generated via WSE 3.0 When I call the proxy via a winforms client I don't have any problem updating the data.

Thanks for your response Bart,
So do you mean that the "COM_NAME" is a normal public field rather than a property in your objectdatasoure or the configured dataobject class? If so, based on my understanding, those datacontrol which define some XXXField property use reflection to dynamically query the member (of that field name) in the class, and it only support querying Properties rather than field, so if you're using field, I'd suggest you try changing it to property instead.... In addition, if convenient, you can also create a simplified example of the datasource object you used to us so that we can have a more detailed view on it...

Hi Steven, showing the data is no problem. The GetCompany funtion works fine.
It is the update that isn't working and producing this error. Can I send you the proxy class by email? Thanks Bart [quoted text, click to view] "Steven Cheng[MSFT]" wrote:

Hi Bart,
Thanks for the followup. Seems a bit strange. Would you try just creating a list (Array) of the objects returned by "GetCompany" method, and directly bind the list to the GridView control so see whether it can display well? Or If possible you can simplified the WSDL document and paste to me so that I can create a proxy class locally and test it ....

Thanks for your response.
Sorry that I missed the point that the error occur when you updating it.... well, you can send me that file through the email in my signature(remove the "online" in it...), You can also attach a simplifed asp.net page code so that I can also have a look...

Hi, Steven,
Thanks for clearing this out. Now I have the problem that a datarow doesn't have a parameterless contructor. Does it mean that I have to create a class with a property for each field? Or is there a way to let the wsewsdl3 tool generate it? Thanks again [quoted text, click to view] "Steven Cheng[MSFT]" wrote:

Hi Bart,
I've had a look into the code you sent me. And I think the problem is the currently updating model you're using. As for the ASP.NET template databound controls (GridView, DetailsView......). They can be bound to a List of data (like DataTable, Array, DataView....). However, when performing updating or deleting, only single Row(Record) can be passed from DataBound control to DataSource control, so your the "UpdateMethod" of your BusinessObject defined in the ObjectDataSource must be a function which accept a single record object (a DataRow, a object class) rather than a DataTable or typedDataTAble..... e.g... we should define a method like: BusinessProxy.UpdateCompanyTableRow(CompanyTableRow row) which accept a class instance which has the property that mapped to the fields in the databound control( GridView or DetailsView...) rather than BusinessProxy.SaveCompany(CompanyDataTable) Thus, we can get why the original page always report "can not found property .... error ", yes? Because it try find a "COM_NAME" field on the CompanyTable instance which is surely impossible.... If there anything unclear, please feel free to post here.

Thanks for your reply Bart,
I think we have to manually do some modification in the generated proxy classes's code. So far the wsewsdl3.exe will only help generate a normal standard proxy class and there has few options for defining the detailed class's code style, etc..... Also, as for ObjectDataSource, it dosn't matter where the class come or how does it get generated, but require it to meet the requirements (like the default constructor needed....).
