I'm trying to get this working in a test application before adding it to my main project, so that's why the names of controls are the way they are.The errors I'm trying to show are if "Inventory ID", "Cart" and "Shelf" do not match. When they don't match it doesn't update, which is what it is supposed to do. However, if they do match they update just fine but also show the Inventory ID error. If I comment out that ElseIf for the Inventory, it throws the Cart error. It's like the ElseIf blocks get called even if the If statement is true...

I have a form and in that form is a datagridview listing information from a table in a database. The datagrid is setup as read only and the user is unable to move the columns around. The purpose of the datagrid is to allow the user to select entire records and press a menu button that does some action on them. To make it easier to use the very first column in an unbound data column that I fill with a number representing the row count so 1,2,3,4.... this makes it easier for the user to count how many rows he has selected.
The problem is that the unbound column moves to the last column in the datagrid at random times.This only happens in development not after the application has been deployed. Its annoying because lets say I go in to add a label or change a menu item on the form that has nothing to do with the datagrid I have to make sure that the unbound column hasn't moved.Has anyone else had this problem mixing bound and unbound columns in a datagridview.

View 12 RepliesI am struggling to understand fully, I need to bind data from an access database to a datagridview. (the DB simply holds a list of product with their stock code, description etc) I need to bind this datagridview to a products collection without using a dataset to bind to the datagridview. I really don't understand this fully.
View 5 RepliesI have a database that dynamically loads from Access into a datagridview. I have to enter data manually into one column in this datagridview. I need to be able to perform calculations to this data, for example I need to sum the data in this column, sqaure it and substract it from individual sqaures of the data in the cells. I should be able to sum it sum(22,33,44,53,67,23)^2-sum(22^2,33^2,...23^2). The number of columns keep changing depending on the database I choose to load, so I need to code this dynamically too. I am not really a VB person. I did the same in excel using Visual Basic and I am trying to do it in this Visual Basic environment.I built a tool in excel(VBA) that do some statistical calculations and data analysis and I am trying to build the same in Visual Basic.
