C datagrid cellvalidating
Can anyone show me how to get my array displayed in a datagrid or even a text file. My array below: string[,] Hrs Worked Table = new string[qry.Total Rows, 24]; /* sample project is available //GOOD SITE File/mahesh/Array List Binding10212005102338AM/Array List Article.aspx?column, its value is tested for validity by checking that it is not empty. If the event handler for the Cell Validating event finds that the value is an empty string, the Data Grid View prevents the user from exiting the cell until a non-empty string is entered. Since i have a column name as "Item Name" which is supposed to be entered as text there is an issue in the code.It generates an error message when i type in the name of the item. Today End Sub End Class Public Class Courses Inherits Observable Collection(Of Course) Sub New() Me. Memberwise Clone(), Course) End Sub Public Sub Cancel Edit() Implements IEditable Object. Begin Edit If in Edit Then Return in Edit = True backup Copy = CType(Me.
Cancel Edit If Not in Edit Then Return in Edit = False Me.
