[Nouman Zaheer]

Hi
i have a dataset in which there are two table joined,i made it hirerechal in the grid in format say
INVOICE NO 1
LINE NO 1, QTY,PRICE,..
INVOICE NO 2
LINE NO 1, QTY,PRICE,..
LINE NO 1, QTY,PRICE,..
.....
now if the user click on the INVOICE NO column i want to do something like moving to "INVOICE HEADER TAB" and if user clicks on any of the LINES then i want to move "LINES TAB"
let me know is it possible ? i have done this with my datagrid in this way

Dim i As Int16 = gridDataBoundGrid1.CurrentCell.RowIndex
If i = -1 Then
Else
'Dim rowcount As Integer = dgInvoiceHeader.CurrentCell.RowNumber
''Dim colCount As Integer = dgInvoiceHeader.CurrentCell.ColumnNumber

Dim rowcount As Integer = i
''Dim cellvalue As String = dgInvoiceHeader.Item(rowcount, 0)
If Not IsDBNull(gridDataBoundGrid1.Item(rowcount, 0).Text) Then
Dim cellvalue As String = gridDataBoundGrid1.Item(rowcount, 2).Text
Dim dataMember As String = gridDataBoundGrid1.DataMember
'Dim val As String = dgInvoiceHeader.Item(index, 0)
Select Case dataMember
Case Is = "InvNo"
Me.tabCustomProcess.SelectedIndex = 3
Dim foundRow As Object
foundRow = getRow("DETC_InvNo", cellvalue, dtInvDetails)
''SET DETC_ID
o_7501.DETC_ID = IIf(Not foundRow(0)("DETC_ID") Is Nothing, foundRow(0)("DETC_ID"), "")
Me.CtlInvoiceHeader1.InvLineID = o_7501.DETC_ID
Me.CtlW7501AddLines1.InvLineID = o_7501.DETC_ID
Case Is = "InvNo.InvHeaderToInvDetails"
''SET DETC_ID
o_7501.DETC_ID = cellvalue
Me.tabCustomProcess.SelectedIndex = 4
Me.CtlInvoiceHeader1.InvLineID = o_7501.DETC_ID
Me.CtlW7501AddLines1.InvLineID = o_7501.DETC_ID
Case Is = "InvDetails"
''SET DETC_ID
o_7501.DETC_ID = cellvalue
Me.tabCustomProcess.SelectedIndex = 4
Me.CtlInvoiceHeader1.InvLineID = o_7501.DETC_ID
Me.CtlW7501AddLines1.InvLineID = o_7501.DETC_ID
End Select
DisplayInvoiceTotal()
If SelectedDocument = "7501" Then
CtlW7501AddLines1.ImporterID = CtlW75011.cbo_SHC_Importer_ID.SelectedValue
CtlW7501AddLines1.EntryType = CtlW75011.cbo_CEC_TypeCode.getDisplayFieldValue("ETYC_Code")
Else
CtlW7501AddLines1.ImporterID = Ctl34611.cbo_SHC_Importer_ID.SelectedValue
CtlW7501AddLines1.EntryType = Ctl34611.cbo_CEC_TypeCode.getDisplayFieldValue("ETYC_Code")
End If
''Read the values of all ID's and Set in to the Class
o_7501.DETC_InvNo = CtlInvoiceHeader1.txt_DETC_Invno.Text.Trim
o_7501.SHC_ID = CtlW7501AddLines1.getSHC_ID
o_7501.IRC_ID = CtlW7501AddLines1.getIRC_ID
o_7501.CHC_ID = CtlW7501AddLines1.getCEC_ID
End If
End If

If I understand what you need, you can handle the CellClick event, and get the information there. One place to look for information like which hierarchy level you are on is to get the GridBoundRecordState for the clicked row. You can get the values directly from the grid. Here is a little code.

private void gridDataBoundGrid1_CellClick(object sender, .GridCellClickEventArgs e)
{
	GridBoundRecordState rs = this.gridDataBoundGrid1.Binder.GetRecordStateAtRowIndex(e.RowIndex);
	Console.WriteLine("level: {0}   value in col 1: {1}", rs.LevelIndex, 
				this.gridDataBoundGrid1[e.RowIndex, 1].Text);
}
