Dev Express DataGrid cell cannot change a value in VB.NET
The first 3 columns of my datagrid in Dev Express are loaded from a datasource. I have 2 more columns: AccountID (ID Akun) and GridColumn1, created via datagrid designer and for some reason I can't change their values.
When I type a value in a cell for AccountID (ID Akun) or GridColumn1 columns and then move to another cell, the entered value into the previous cell disappears. Also when I try to create a new column again then always have the same result that the column cell gets empty.
How do I create a column? I simply use the designer page and then click on Add Column icon.
Below is the screenshot.
What could possibly go wrong and provoke the empty cell behaviour?
Note that I have no any changeValue or click cell event configured.
So, I found the solution.
The problem was in the datasource class. I have a class named "SalaryType" that does not have the "AccountID" property, so when loading the datasource from "SalaryType" class, it is not able to edit a column which does not come from the "SalaryType" class.
To fix it, I added the "AccountID" property and defined get & set methods to access and update its value. And the cell editing works now.
