Amna,

I believe that you are trying to just setup the parent-child relationships if I am not mistaken. There are a number of samples on this as well as documentation. As far as binding to a grid, that is great. You will want to use the BusinessBindingSource that wraps a BO and allows direct binding to a grid.

My first suggestion would be to download and install the StrataFlix sample. This sample shows everything that you are trying to do in regards to setting up parent-child relationships as well as using our ChildFormDialog (if necessary). Adding in the grid portion is the easy part.

This might be the best place to start and then we can field questions from there.

[code]
'
'get value of current row
'
Private Sub loadQByID_Grid()
Dim ds As New DataSet()
Dim dr As DataGridViewRow = gv.CurrentRow
Dim str As Integer = Convert.ToInt16(dr.Cells(0).Value.ToString())
Try
ds = getQuestionByID(str)
txtContent.Text = ds.Tables(0).Rows(0).Item(1)
Catch ex As Exception
Dim strError As String = "Error : " + ex.Message()
End Try
End Sub
[/code]

This above code, I use DataGridView.
I want to use GridControl (DevExpress).
But when I used it, I don't see any object [b]DataGridViewRow[/b] and method [b]CurrentRow[/b]
How do I use GridControl (DevExpress) to get value of current row.
Please help me
Regards
PS: you can use C# to solve

No need to apologize...I am so glad that we are able to communicate. That is wonderful!

If the datasource is available at design-time, then the columns will be setup with the default bindings; however, if it is not available, then you will need to specify the FieldName for each column. The FieldName property is categorized under the Data section when viewing the Columns in the Designer. The Caption property, located in the Appearance section, will set the name of the header in the column.

Hope that helps!
Bill

A grid control can have many grid views. A new instance of the grid control will have one grid view by default (gridView1). Using the designer you can rename it, add new views, etc. I just used the sample naming convention of "MyGridView" just to give you an idea of how to access the data in the grid.

Have fun!
Bill
