• Re: Casting LINQ as Typed Data Table (using LINQ Results and ObjectDataSource for Filtering)

  OMG If you want to post a "I don't think that's a good idea anyway" reply, at least add something to help the situation! The code I have posted is a simplification of what I am trying to do . It illustrates the problem in as simple terms as possible. Do you really want me to post hundreds of lines of classes, page-behind and interactions so you can sift through and approve them before you answer?

• Casting LINQ as Typed Data Table (using LINQ Results and ObjectDataSource for Filtering)

  I have a simple setup of a Typed DataSet connected to a ObjectDataSource. I am using a middle tier function for my CRUD and filtering. I am experimenting with using LINQ to filter the data. But quite simply The following code doesnt work: ---- Dim uTable, returnTable As UserDataTable uTable = _Adapter.GetData() Dim results = From rows In uTable.Rows Select rows returnTable = results ---------- But "results" can not be converted to the type UserDataTable. "results" is of the type

• Dynamically Create Gridviews

  I have a nice little gridview on my page. But I want to create many instances of this gridview on the same page, and I want to dynamically create a new gridview at runtime. (For example I want to have a categories table, and if the user enters a new category, then a new gridview will be boudn to that category type) It's straight forward as to how to dynamically add a textbox, but is there a good way to take a snapshot of my lovely gridview, and dynamically stamp it out for each catagory? Alternately

• Re: DataAdapter Handling NULL Values

  <Sarcasm> OK, since no one here or at MS has any reason for not allowing NULLs or can state the prefered method for how to handle NULLs coming back from the database, then I will be forced to make something up. Tomorrow I will tell my SQL counterpart that, from now on, whenever he encounters a NULL, wrap it in an ISNULL and return the number -12,456. Feel free to adopt my new standard. </Sarcasm>

• Re: Invalid postback or callback argument.

  I noticed that in my case, the Invalid Post back was not the real problem. Actualy the page was hanging. Only when I clicked the button twice did I get the error. (I still don't know why it's hanging)

• DataAdapter Handling NULL Values

  (After some research on the forums I can't seem to get an answer on this one. I'll keep it simple.) My SQL table has NULL values in an Integer Column . I create a DataAdapter and DataTable for this table. When I fetch the data it crashes saying "Columns of type INT can not be NULL " (paraphrase) OK, so do I have to add ISNULL around every column that could be NULL?? What does Microsoft intend for me to do? Should I ISNULL it to -1? Should ISNULL it ti 0? I can "get it to work" , but I don't want

• Re: Offer Generic .NET page to 100 customers

  Update: Masterpages worked very well. I simply created one master page for each site. When the user logs in I determien where they are from. Then when each page loads I simply change their master page programatically. Works like a charm.
