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


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

Open in new window

I have corrected a couple of typos in the snippets!!
'First snippet

  

   With xa

        .InsertRows lrowposition

        .VALUE(lrowposition, 1) = "New"

        .VALUE(lrowposition, 2) = "Data"

        .VALUE(lrowposition, 3) = "in the row"

    End With

    

    TDBGrid1.ReBind

 

'Second snippet

 

result=xa.InsertRows lrowposition,3

'result should be 3

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
