From: MikeG0930 on 18 Feb 2010 15:59 Is it possible to create an array from a DataGridViewColumn? I have a form that is bound to a DataSet of 2 tables related. I dragged Table1 onto the form as Details and Table2 as a DataGridView. The tables are synched so that when I use the navigation control, the related records of the DataGridView match the parent table. I want to be able to create an array of a column (let's call the column "Name"). So, if the column "Name" contained 6 names, the array would hold the 6 names; if it had 3 names then the array would have 3 names all depending on what record of Table1 was navigated to. How would I go about this? Thanks.

Using this code I am getting an exception: Unable to cast object of type 'System.String' to type 'System.String[]'. Here is the code: Private Sub FamilyTree_Load(ByVal sender As Object, _ ByVal e As System.EventArgs) Handles Me.Load Dim i As Integer Dim pintRowCount As Integer Dim pstrChildren() As String Dim pstrChild As String pintRowCount = FamilyMembers.dgChildren.Rows.Count - 1 ReDim pstrChildren(i) For i = 0 To pintRowCount - 1 pstrChildren = FamilyMembers.dgChildren.Rows(i).Cells(2).Value lstChildren.Items.Add(pstrChildren(i)) Next End Sub Please help?

Found the error from some help on one of the forums. Changed this line: pstrChildren = FamilyMembers.dgChildren.Rows(i).Cells(2).Value to this: pstrChildren(i) = FamilyMembers.dgChildren.Rows(i).Cells(2).Value "MikeG0930" wrote: > Since nobody seems to have an answer for me, I decided to try it on my own. > Using this code I am getting an exception: > Unable to cast object of type 'System.String' to type 'System.String[]'. > Here is the code: > Private Sub FamilyTree_Load(ByVal sender As Object, _ > ByVal e As System.EventArgs) Handles Me.Load > Dim i As Integer > Dim pintRowCount As Integer > Dim pstrChildren() As String > Dim pstrChild As String > > pintRowCount = FamilyMembers.dgChildren.Rows.Count - 1 > ReDim pstrChildren(i) > > For i = 0 To pintRowCount - 1 > pstrChildren = FamilyMembers.dgChildren.Rows(i).Cells(2).Value > lstChildren.Items.Add(pstrChildren(i)) > Next > > End Sub > > Please help? > |
