| DataGridView integer problem?
Hey people, I'm not sure what is wrong with this code and any help would be greatly appreciated:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim i As Integer = DGVShops.CurrentRow.Index
Dim c As Integer = DGVShops.Item(0, i).Value ' gets value from selected rows first column
Dim s As String = DGVShops.Item(2, i).Value ' gets a string which is the name (3rd column)
ShowMe(c, s) ' passes parameters
End Sub
Private Sub ShowMe(ByVal c, ByVal s)
Select Case c ' which should be an integer...
Case 1 To 46
label.Text = (s + " some text " + c)
End Select
End Sub
I dont think it is passed as a value... although when I used .tostring i managed to get the interger shown. |

Where is the problem?
If the problem is with Dim c As Integer = DGVShops.Item(0, i).Value Then try using CType Dim c As Integer = CType(DGVShops.Item(0, i).Value, Integer) If the problem is the table returning a string and not an integer then this should fix it. |

hi
i think the problem is while fetching the grid value this should be like this...
variable = datagrid1.Item(datagrid1.CurrentRowIndex, 0) ' this will give u current rows 0th column value
like wise.
check this.
Best luck. |

| Re: DataGridView integer problem?
Thanks for your suggestions but I fixed the code by changing the integer to a string, I think Select Case didn't like the integer for some reason?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim i As Integer = DGVShops.CurrentRow.Index
Dim c As Integer = DGVShops.Item(0, i).Value ' gets value from selected rows first column
Dim s As String = DGVShops.Item(2, i).Value ' gets a string which is the name (3rd column)
ShowMe(c, s) ' passes parameters
End Sub
Private Sub ShowMe(ByVal c, ByVal s)
Select Case c ' which should be an integer...
Case 1 To 46
label.Text = (s + " some text " + c)
End Select
End SubPrivate Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim i As Integer = DGVShops.CurrentRow.Index
Dim c As string= DGVShops.Item(0, i).Value ' gets value from selected rows first column
Dim s As String = DGVShops.Item(2, i).Value ' gets a string which is the name (3rd column)
ShowMe(c, s) ' passes parameters
End Sub
Private Sub ShowMe(ByVal c, ByVal s)
Select Case c ' which should be an integer...
Case 1 To 46
label.Text = (s + " some text " + c)
End Select
End Sub |
