Placing Value Member Of A Combobox In The Display Member Of Another Combobox
Jan 14, 2012I have been battling with this problem for months with virtually no success. I am using Visual Studio 2008 Professional. The database is Microsoft SQL 2005.
I have two combo boxes - both bound to database tables. These are: Combo box 1 is for "VAT" and is bound to the VAT table. This table has 3 columns configured as shown below:
[Code]....
The commented out code was my pathetic attempt to put the Value member of one combo box into the display of the other. This obviously does not work and my web browser, when using Google, is full of purple headers showing the sites that I have visited looking for an answer.
When I have this working, I want to use the feature in a datagridview which may make a difference to how the problem is approached.
ComboBox / Binding / Display Member & Value Member
Aug 31, 2011I know I have done this before and as I remember it should be really easy. But for some strange reason I can't do it now and I am about to jump off the building.I will make it simple:Two tables, one is just a list of products and their code.The other table: "details" has a field named product. I want to store only the code there.In the second table's entry form, I am putting a combobox. This combo box should display the list of products, their names, but depending on which one is selected, the code is what is passed to the table "details". Currently If I set the display member to product and the value member to code it still pases the product to the binded data source.
View 3 RepliesVB GridView Control Does Not Allow Code To Access Column When Column Has Visible Property Set To False
Apr 1, 2010VB GridView control will not allow code in the vb code file to access a data column that has its visible property set to false. When it is set to true, the data column can be accessed with no problem. Any suggestions as to how to correct this? I have looked through the documentation, text books, and I have not found anything that gave me any clue as to what the problem could be. I thought that the property was just applied to the column, not that it would remove the column from being accessible.

Get Value Member Of Combobox?
Dec 28, 2009Let's say I bound a combobox to a datatable. How can I get the valuemember of the currently selected item in the combobox (for example, when I have to save the data, I need to get the valuemember - PatronTypePK - of the currently selected item in cmbPatronType)? And can anyone check if I made the code correctly or if there are any programming practice errors/inconsistencies? I wanted to fetch two tables into a single dataset (Patron, PatronType). Do I have to make a datatable for each, or can I simply use the dataadapter?[code]...

Select Object Member From Combobox List Of Objects
Nov 16, 2011I have a combo box that is populated with a list of objects (corresponding to all employee rows from a database that meet the criteria IsTech). These are not entity objects though, I have created my own class that stores the member values of each row from the DB. I have set the DisplayMemberPath to EmployeeId so the Combo box display the EmployeeId ( an integer ) member of my object. Ie. right now there are only 2 IsTech employees in my DB so the combobox displays the numbers 3 and 8 ( their EmployeeIDs).
