I'm new to ASP.net 3.5 and trying to create a test site so I can figure out how to use it in the real world. I have created a FormView (Formview1) based on a Client table using Linq Data Sources. The page includes a DropDownList to lookup Clients. I have added a list option (<asp:ListOption value="" Text="(Select Client)" and set AppendDataBoundItems=true so my added option is displayed. I decided to try to use Formview with only the Edit and Insert Modes, and I have set the Default Mode = Insert. When you open the page, a blank Client record is displayed.
The Client record contains serveral lookup fields and they have drop down lists for each. When I select a client from the Client DropDownList, is get the following message 'ddlClientType' has a SelectedValue which is invalid because it does not exist in the list of items I had this problem before and decided the best way to handle this (in the interim) was to turn off foreign key constraints for each of the lookup fields (e.g. ClientType) in SQL Server. That worked for 2-3 days. Now the problem has started again.
When I develop in other applications, I would simply create a lookup data source based on a Union Query with the actual data and a blank record. How can you do this using Linq DataSources. Can you get access and modify the queries?

Basically i want to create combo box with multiple columns, I am aware that there is couple different solutions on the web, but I have decided to go for SQL query as I think it does not takes as much resources as Ajax Extender method, or label+GridView method,
Result of the query is:
DELL................Power Vault Ultrium LTO 4
1
Plextor.............PX-810SA
2
Asus................CRW-5232A3

Dell................PowerVault 110T LTO2

As you can see it columns are not in line, I spent hours trying to find the way to "assign static length for SQL Columns".I want to assign 20 chars block for BackupDriveMake, and the same for BackupDriveModel and then combine them under one name using AS option. So if for example if backupmake takes 4 chars it will fill rest with blank spaces.
Example:
DELL
Power Vault Ultrium LTO 4
Plextor
PX-810SA
Asus
CRW-5232A3

View 1 RepliesThere is a field called school which is a dropdown menu, I manually edit items and made it like these: select school, name of 6 elementaries and 2 middle schools, and a high school.I have another field called grade level, which is a drop down menu too, i manually entered the grade items for it: select grade, Kindergarten, 1, 2, 3......12.
I would like after user selects a school in the drop down menu, the field called grade level dropdown box' data source will be updated according to school. For example, if it is a middle school selected, the data source of grade level will be updated to 6, 7 8 grade, if it is elementary the grade will be updated to 1, 2, 3, 4 5 etc. In this way later, when user goes to select grade it will show appropriate grade level lists according to schools.
