• Re: FileUpload to database (doc, xls, pdf, picture, etc.)

  Thanks Steve, that was it. I registered the handler in web.config and I was able to invoke my FileHandler.axd code. However I'm running into another issue. I'm using EF and I'm running into the following error when using DbImage sample. // Items.Where(row => row.ID == 1).Single() var singleWhereCall = LinqExpressionHelper.BuildSingleItemQuery(query, metaTable, primaryKeyValues.ToArray()); // Items.Where(row => row.ID == 1).Single().Picture var fileBytes = Expression.Property(singleWhereCall

  Yes I need to use FirstOrDefault. Can you show me how I can modify the above code to use that?

• Re: FileUpload to database (doc, xls, pdf, picture, etc.)

  Thanks Steve. that worked! Instead of making the change to the LinQExpressionHelp class I made the change directly in the handler class. Now I'm able to upload and download files from database. var whereCall = LinqExpressionHelper.BuildItemsQuery(query, metaTable,cols,primaryKeyValues.ToArray()); var singleWhereCall = Expression.Call(typeof(Queryable), "FirstOrDefault", new Type[] { metaTable.EntityType }, whereCall); //var singleWhereCall = LinqExpressionHelper.BuildSingleItemQuery

  Hi Steve, I see that in your example, you are saving the files to the file system. I need something that saves the file to the database and retrieves it. Thanks

• Re: FileUpload to database (doc, xls, pdf, picture, etc.)

  Thanks Steve, I've already looked at this and I'm trying to adapt DbImage sample from the futures to accomplish what I want. I'm having trouble invoking my custom FileHandler. I have create a custom FeildTemplate called FileImage and added a custom HttpHandler called FileHandler to the App_code folder. But when I set the ImageUrl to "~/FileHandler.axd?Table=xxxx&Field=yyyy&pk=1.....", the processRequest() method never gets invoked. When I manually type in the URL as

• FileUpload to database (doc, xls, pdf, picture, etc.)

  Hi, I need to upload any file (picture, doc, pdf, excel etc.) to the database. In display mode, I need to display the file name with a hyperlink. When this hyperlink is clicked the file should be downloaded from the database and displayed (embedded in the browser) or promt for saving it. When in edit mode, both the link and file upload control should be displayed to enable replacing the original file or inserting a new file. I have looked at DBImage and FileUpload examples but they are not quite

• Re: Filter by non-FK columns

  Thanks Steve, that explains it. I will convert my Integer PK field to a string type. I need one more type of filter for filtering by date columns. Something that can support a date range on a date column would be best. Any ideas or resources you can point me to? Thanks again for all your help.

• Re: Filter by non-FK columns

  Thanks Steve, I was able to integrate you AnyColumnAutoCompleteFilter into my EF project without any issues and it works great. But it doesn't work with the Integer PK columns. I noticed that in your article you referenced a forum thread where another user had the exact same issue. Have you been able to figure why it doesn't work with numeric PK columns? PS: I don't want to use the Integer filter because it loads all values in a drop down and I will have upto 20,000 values in it.

• Filter by non-FK columns

  Does anyone have ideas or samples on how to setup filtering on a non-FK column? I'm using EF. I have looked at the AutoComplteFilter samples but they are all for the FK columns. I need something similar for non-FK column. Thanks

• Re: Insert Child data with the Parent data on the same page

  Thanks for the idea. I was able to get around this by making the PK of the parent table a GUID. I then generate the new guid in the OnSavingChanges event handler and use it to save the child data as well. What I am now running into is an issue setting the correct datacontext for the EntityDataSource control in the FieldTemplate ChildrenGrid. Steve, do you have any equivalent of your ChildrenGrid article that works with EntityDataSource?
