...<field> field not updateable
I am using a MS Access backend on Windows 2000 using FAT (not NTFS) System.
I have designed a web page which inserts data into a table (which works), but if i try and update the table, I get a '<field> field not updateable.
The field is not a primary key or an AutoNumber, its just a text column.
Any Ideas ?
.... before you ask.
I do have a primary key within the table which is an autonumber......how to connect a database-field to an input-field

I'm using XE4 Pro UPd 1 with FireDAC 8.0.5
I'm porting a database application from dbExpress to FireDAC still using the same SQL Server 2008 R2 database.
I have made a basic setup with a data module and set up tadQueries using cascading updates as described in the manual to handle the relations. All queries execute fine in the IDE and the Field lists are all populated.
In the program I first open the queries in hierarchical order. All is well: I can see the data I want in controls as expected, also from detail queries.
I then navigate to another (existing) record in the maste...Displaying fields in same was as <%=(field)%> in .net

First impressions are good, there are some great tools there to save a load of time with the Datagrids etc.
However I am stuck on how to do something I use 99% of my time in ASP and is holding me up!
Before I would create a recordset using
sSQL = "SELECT Name FROM Albums WHERE Uid = 1 ORDER BY Name" Set RsAlbum = Conn.Execute(sSQL)
Name = RsAlbum("Name")
Then in the HTML I could display the result by using

Could someone please help me find the missing piece to this puzzle. My issue is when i execute this form without entering a new image in upload field, it overwrites the field in the database. I'm not to sure how to pass the value, or just not update that field.

I'm sure this is REALLY simple, but I can't seem to figure it out. I have a CMS for a client, and they can upload images to the server. When creating new records, this feature works like a charm. However, when they go to edit a record, the uploadFile text box doesn't fill with the data already contained in the database for that file upload. Is there some way to bind text to the text box for asp:uploadFile?
I don't think it is possible. If you check the SDK most of the fileupload's properties are readonly (including filename).

I've created a form that has a Serial Number entry on it. I want the user to either be able to type in a new serial, or select one from the dropdown list. The problem I've run in to is that when I try and use the same Name on both ControlParameters, it conflicts.Here's the code I have, the bottom two control parameters are the ones that conflict:

I've encountered a technical issue while building a business framework based upon dbx : For some business objects I need some extra read/write fields in the clientdataset that models them. Technically, I have a classic tclientdataset connected to tdatasetprovider connected to tsqldataset. When I define myfields at runtime I get an error when opening the clientdataset because of unknown fields for the non-database fields ( I would have hoped they would simply get null values ).
I tried many different things but can't get it to work.
My current workaround is to select extra d...Adding field types to the GridView Edit Columns (or Fields) dialog
I have a new field type derived from BoundField for a custom grid control derived from GridView. I want the new field types to appear in the Edit Columns (or Fields) dialog.
It seems like a simple idea but I have not been able to determine what to override to add the new types.
Any direction would be appreciated.Ron Kreykes

I have to add Template field to Gridview and use data binding statement such as "<%# GetData(Eval("DType").ToString())%>" in the ItemTemplate. so that column retrieve/shows GetData("DType") values.
When user clicks on this column it should redirect the user to another page, showing selected/clikced datarow . I think it is to do with Dynamic Hyperlink Field.
I like to know can a column be a Hyperlink field as well as Template field so that i can use data binidng statement as above and do hyperlink task as well.
your quick suggestion ...
