Hi,

When update the record from DataGrid and gave the update command:

Error:
Update requires a valid UpdateCommand when passes DataRaw collection with modified

Syntax:
For UpdateCommand
----------------------------------------------------------------------
Dim message, title, defaultValue As String

message = "Please Enter an invoive number." ' Set prompt.

Finally

objConn.Dispose()

'objConn.Close()

End Try

' Cleanup

----------------------------------------------------------------------

Update Button Code:
----------------------------------------------------------------------
Private Sub btnDataGridUpdate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDataGridUpdate.Click

Try

da.Update(ds, "invoice_details")

Catch x As Exception

MsgBox(x.Message)

' Error during Update, add code to locate error, reconcile

' and try to update again.

End Try



dg.ReadOnly = True

End Sub

----------------------------------------------------------------------


Please tell me how check my update query syntax,

It doesn't seem like the parameter syntax is correct as you have no @ symbols in the SQL statement.
You can use the Data Adapter Configuration Wizard to generate the command and parameters for you by adding a dataAdapter to the designer, right clicking it and selecting 'Configure Data Adapter...'

Thank,

It is working now,

Error is due to :

da.Dispose()

objConn.Dispose()

When comments these two line it works.

Dim Summary As New ArrayList()
Summary.Add("5,sum(AMOUNT)")
Summary.Add("6,sum(VAT_AMOUNT)")
' Map the array list to the SummaryColumns property of your DataGrid control.
SummaryCols = Summary

' Set the foreground color and the background color for the footer row.
'dg.FooterColor = Brushes.Brown
'dg.FooterFontColor = Brushes.White

' Bind the DataGrid control to the related data.
'dg.BindDataGrid()
MyDataTable = db.DataSet11.Tables(0)
'MyDataTable = ds.Tables(0)

MyDataTable.Columns.Add("ID", System.Type.GetType("System.Boolean"))
MyDataTable.Columns("ID").DefaultValue = True
MyDataTable.Columns("ID").ColumnMapping = MappingType.Hidden
----------------------------------------------------------

Dim data1(2) As Double
Dim im As Integer
im = 0
' Calculate the value for each cell in the footer.
Dim MyArray(2) As String
Dim MyString As String
Try
For Each MyString In SummaryCols
MyArray = MyString.Split(","c)
data1(im) = (MyDataTable.Compute(MyArray(1), "ID is null"))
im = im + 1
Next
InvoiceAmount.Text = (data1(0)).ToString()
VatAmount.Text = (data1(1)).ToString()
InvoiceVatAmount.Text = (data1(1)).ToString()
Dim totalv As Double
Dim totals As String
totalv = data1(0) + data1(1)
InvoiceTotalAmount.Text = totalv.ToString()
---------------------------------------------

This code generate sub-total when i click twice in check box of datagrid twice. How to make it autometically
