Web Forms :: Make The DB And/or Form Change The Available Bin Fields To False
Jan 7, 2011
I'm not entirely sure which forum this belongs in. It works with both my ASP.NET form and my SQL DB.
Okay, I built an application from scratch a couple years ago and am trying to add some functionality so I don't have to do so much manual work.
I have two relevant tables, tableClasses and tableStudent2Class
Classes have 4 possible sessions that are available. These are bin fields which I mark as true if they're available for registration. There are upwards of 40 different classes that are available. Each class has a defined number of slots available (an int field).
The tableStudent2Class connects the tableStudents to tableClasses. There are three fields: classID, classSessionNumber, and studentGUID.
Now, is there some way to make the DB and/or form change the available bin fields to false when they receive a certain number of registrations?
I have a problem that in DetailsView Edit Mode, if I go to edit fields, and set a fields visible property to false, when I update the record through the built in update options it sends a null value. If I change the field back to visible, it passes the data just fine.
Consequently, I tried just setting the field to Read Only = True, and got the same result even though the current values do show up in the edit mode, just read only.Is there anyway to hide the field but still allow it to pass the data it currently has "BACK" into the record.
I have a relatively complex dataset (numerous tables, some with multiple records) generated from reading in an XML file. I need to connect said dataset fields to an ASP form. At the moment I'm assigning them manually, like so in the pageload:
I did some looking into binding the textboxes (and dropdownlists, and checkboxes, and and and...) directly, but it seemed to be too many formats to use.
So this works fine, but as the number of fields increases, those load and unload lists are going to get unwieldy.
I have an Objectdatasource configured with Select, Insert, Update & Delete queries in a Dataset. This datasource is linked to my Gridview. I do not require all fields in the table to be displayed or updated in my grid so i have turned off the Visible property on several.
However, when i go into Edit mode and trigger the UPDATE to the database table, i get NULL values updated in the columns i set False for the Visible property.
How can i remove these columns from the GridView and the Edit mode and still have them UPDATE with their current values instead of being overwritten with NULL's?
i used this tutioral [URL] and i change as per my requirment and i got this gridview its working fine

The form gets created fine but when I click the button and look at the results returned to the server I cannot seem to find the input values. Is there a defined way of accomplishing this?
