databand filter from VB.net

russlunnrusslunn
in FastReport .NET

HI,


I have a filter on a databand that is linked to a prameter [STIAHD.INV_NUM]== ToDecimal([@INVNUM])

when the user clicks an Invoice in a datagrid on my form, i then set the parameter to the Invoice Number

and the previewcontrol displays ony that Invoice


this works well, however..... I need to display ALL the invoices, if there is no invoice selected in the datagrid

i tried

IIF([@INVNUM]=="","",[STIAHD.INV_NUM]== ToDecimal([@INVNUM]))

in the filter but that didnt work.


is it possible to add and remove the filter on the report databand from my vb.net program at runtime?

or is there a way of ignoring the filter if the parameter is "" or is nothing?


Thanks

    i figured this out, (a good nights sleep helped!) so i thought i'd come back and answer my own question.

    maybe it helps someone else in future


     Dim b As DataBand = report1.FindObject("Data1")

     If dgvList.SelectedRows(0).Cells(1).Value.ToString = "Show All" Then

          b.Filter = ""

          report1.SetParameterValue("@Batch", Nothing)

        Else

          b.Filter = "[STIAHD.INV_NUM]== ToDecimal([@Batch])"

          Dim filterValue As String = dgvList.SelectedRows(0).Cells(1).Value

          report1.SetParameterValue("@Batch", filterValue)

        End If

        PreviewControl2.RefreshReport()

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
