I'm using this
tg.InsertMode but it dosn't work.

If you are using the grid in 'Storage' mode with an XArrayDB object to store the data, you use the XArrayDB.InsertRows method to insert new rows.

If you are using it in 'Application' mode and the grid is tied to a VB array, you need to redim the array to insert a new value.

In both cases you then need to use the Rebind method on the grid to refresh the display.

Hi! I am using XArrayDB object . Can you give me example on how to use xArray.insertRows? I'm trying many times but still didn't work!
Thanks!
Hi


Assuming you have a grid called 'Tbdgrid1' which is bound to an XarrayDB object called 'xa', the attached snippets should work. The first adds a new row at row 'lrowposition' and inserts values into the first 3 columns.

The second inserts 3 new rows at row 'lrowposition' and leaves them blank.

The Insertrows method returns the no. of rows added.

Remember to call Tdbgrid1.ReBind after modifying the xArray|Db object, to update the rows shown in the grid.


 'First snippet
  
   With xa
        .InsertRows lrowposition
        .VALUE(lrowposition, 1) = "New"
        .VALUE(lrowpositionw, 2) = "Data"
        .VALUE(lrowposition, 3) = "in the row0
    End With
    
    TDBGrid1.ReBind
 
'Second snippet
 
result=xa.insertrows lnewposition,3
'result should be 3

Hi!  I will try it now but it needs a long time for me to make this trial since i am not good enough in vb6... Thank you so much for your help. I will give you an information any results.. Thanks!
Hi! I'm very sorry but I was not able to get the correct Idea. Can you give some example? I attached the code below I hope you will give me some example base on my code. Thanks!  
Dim x As XArrayDB
Dim DB As New ADODB.Connection
Private Sub Form_Load()
INITG
End Sub
 
Private Sub INITG()
Dim MAXROW As Long, MAXCOL As Long
Set x = New XArrayDB
x.ReDim 0, 0, 0, 10
    For MAXROW = x.LowerBound(1) To x.UpperBound(1)
        For MAXCOL = x.LowerBound(2) To x.UpperBound(2)
            x(MAXROW, MAXCOL) = " "
        Next MAXCOL
    Next MAXROW
With tg
    .Close
'''    .Columns(0).Alignment = 3
'''    .Columns(1).Alignment = 3
'''    .Columns(2).Alignment = 1
'''    .Columns(3).Alignment = 1
'''
'''    .Columns(0).Locked = True
'''    .Columns(2).Locked = False
'''    .Columns(0).Width = 1900
'''    .Columns(1).Width = 3500
'''    .Columns(2).Width = 1500
'''    .Columns(3).Width = 1500
'''     .Columns(3).Locked = True
'''     .Columns(4).Locked = True
'''    .Columns(1).AutoDropDown = True
    .Array = x
End With
End Sub

I have added some more code and comments to yours - hopefully this explains how to add and fill rows in the array and then rebind the grid to display them.
Dim x As XArrayDB
Dim DB As New ADODB.Connection
Private Sub Form_Load()
INITG
End Sub
 
Private Sub INITG()
Dim MAXROW As Long, MAXCOL As Long
Set x = New XArrayDB
 
' Here you are setting up the array with 1 row and 11 columns,
' which are all filled with a space.
x.ReDim 0, 0, 0, 10
    For MAXROW = x.LowerBound(1) To x.UpperBound(1)
        For MAXCOL = x.LowerBound(2) To x.UpperBound(2)
            x(MAXROW, MAXCOL) = " "
        Next MAXCOL
    Next MAXROW
With tg
    .Close
'''    .Columns(0).Alignment = 3
'''    .Columns(1).Alignment = 3
'''    .Columns(2).Alignment = 1
'''    .Columns(3).Alignment = 1
'''
'''    .Columns(0).Locked = True
'''    .Columns(2).Locked = False
'''    .Columns(0).Width = 1900
'''    .Columns(1).Width = 3500
'''    .Columns(2).Width = 1500
'''    .Columns(3).Width = 1500
'''     .Columns(3).Locked = True
'''     .Columns(4).Locked = True
'''    .Columns(1).AutoDropDown = True
 
' Here you assigning the array as the datasource for the grid
    .Array = x
 
' Now we need to put some data in the array using the AppendRows or InsertRows methods
' You will perhaps do this by reading from a database table
        .InsertRows 0,3               'this inserts 3 rows before the blank row that you already have
        .VALUE(0, 0) = "New"
        .VALUE(0, 1) = "Data"
        .VALUE(0, 2) = "in the first row"
        '.. continue until all columns are filled
        .VALUE(1, 0) = "Some More"
        .VALUE(1, 1) = "Data"
        .VALUE(1, 2) = "in the second row"
        '.. continue until all columns are filled
        .VALUE(2, 0) = "Some More"
        .VALUE(2, 1) = "Data"
        .VALUE(2, 2) = "in the third row"
        '.. continue until all columns are filled
 
' Finally you need to rebind the grid to the new values in the array    
    TDBGrid1.ReBind
 
' The grid should now appear with data 3 rows of data and a blank row at the end.
 
End With
End Sub
