e_docSelection_changed question

[lidds]

I have started developing my own comment form as it gives some more features to my users for my tool than the currently one. Everything seems to be going OK, apart from this one issue.

I am intercepting the e_docSelection_changed event so that when the user selects a markup from the document it automatically selects the comment from my new comment grid, using the code below:

Code: Select all

						Dim Doc As PDFXEdit.IPXV_Document = CType(e.pFrom, PDFXEdit.IPXV_Document)
                        Dim nLen As UInteger = e.pEvent.Param2
                        Dim buffer = New Integer(nLen - 1) {}
                        Dim ptr As IntPtr = New IntPtr(e.pEvent.Param1)

                        If nLen = 0 Then
                            ' Deselect all rows as nothing is selected in the PDF document
                            MISData.Instance.frmDocDesigner.selectAnnotGridRow(-1)
                        Else
                            Marshal.Copy(ptr, buffer, 0, CInt(nLen))
                            For i As UInteger = 0 To nLen - 1
                                Dim docSel As PDFXEdit.IPXV_DocSelection = Doc.GetSelCluster(buffer(i))
                                Dim annotSel As PDFXEdit.IPXV_AnnotSelection = TryCast(docSel, PDFXEdit.IPXV_AnnotSelection)
                                If annotSel IsNot Nothing Then
                                    If annotSel.Items.Count <> 0 Then
                                        For annotCount As UInteger = 0 To annotSel.Items.Count - 1
                                            Dim rowHandle As Integer = commonCode.GetRowHandleByColumnValue(MISData.Instance.frmDocDesigner.gridAnnotations, "annotOID", annotSel.Items(annotCount).Name)

                                            If rowHandle <> -1 Then
                                                MISData.Instance.frmDocDesigner.selectAnnotGridRow(rowHandle)
                                            End If
                                        Next
                                    End If
                                End If
                            Next
                        End If

The above code works fine when selecting a markup individually, however is I try to draw a selected region and select multiple markups it stops the drawing of the completed region on the document.

I was wondering if there is an event that is raised when a selected region is completed? If not is there a way that you can think of that I can get this executing correctly?

Thanks

Hello Simon,

What do you mean by "selecting a region"?

Hi Alex,

What I mean is when I depress the left mouse button and stretch a selection window to select multiple markups.

I hope that clarifies?

Thanks

Hello lidds,

From what I see, you are selecting something on your form, that means that you are moving the focus from the Control. That can cause the selection to stop dragging as you describe.

Cheers,
Alex

Hi Alex,

Yes you are correct, this was the error, should have seen this.

Instead a used a selection flag and intercepted the left button up mouse event.

Thanks for you help
