I have a flygrid with one hierarchy column and other \"usual\" columns.
When i want to use the enter to trigger an action i get a error:

Index out of bounds!

Stacktrace:

bei .8.get_Item(Int32 index)
   bei NineRays.Windows.Forms.Data.VirtualNode.()
   bei NineRays.Windows.Forms.Data.NodeBase.GetFirst()
   bei NineRays.Windows.Forms.Data.NodeBase.GetNext()

   bei System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
   bei System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

Any help is very much appreciated.

I also noticed that although i have an event handler for this event, the event handler is never invoked in combination with the hierachical column.

So is it a bug in the flygrid component itself?

Thank you.

Do you mean you're using the  Enter key and that causes the error above?

Can you please also send me a code from your event handler?

Also, why do you need the hierarchical column?

Hello,

yes I mean that i get the exception when i use the ENTER key.

Another problem is that the event (KeyUp) is never invoked.

So here is the code:

// If the pressed key was the enter key
            if (e.KeyCode == Keys.Enter)
            {
                String number = \"\";
                // Get the selected nodes
                NodeBase[] selection = flyGrid.Rows.SelectedNodes;

                // Proceed only if one entry has been selected
                if (selection.Length == 1)
                {
                    // If not nodes has been selected
                    if (flyGrid.Selected != null)
                    {
                        // Fetch the data from the datatable
                        DataRow callRow = m_dtprovider.GetDataTable().Rows[flyGrid.Selected.Index];

                        if (m_config.PeriodViewAktiv)
                        {
                            number = this.GetNumberForRow();
                        }
                        else
                        {
                            // Get the number
                            number = (String)callRow[DataTableProvider.InternalColumnNames.InternationalId.ToString()];
                        }

                        if (number != null && !number.Equals(\"\"))
                        {
                            // Call the number  
                            this.InitConnection(number);
                        }
                    }
                }
            }


Why i use the hierachical column? The reasons is that i need a hierachical view. What would you suggest?

Regards,

Sebastian

Sebastian,

I created a test case similar to your configuration. And got everything behaving as it should.

What if you comment out your key press handler. Do you still get the error?

Sebastian,

The best and 100% way to find and fix a bug is a simple demo application that we can run locally and fix the issue.

Please, copy the flygrid with all its setting into a simple windows forms application with the only testing form. Then zip your project and send to support*9rays.net

Hi,

i tried  to send you the demo project but your mail filter seem to reject it because of the attachment.

I made a simple demo app but without the exact settings of my current project. I added one hierachical column and some usual text columns.

When i then started the project and pressed the ENTER key i got a null pointer exception.

I have no idea where this comes from.

Nevertheless...i need a solution for this problem!

Regards,

Sebastian
