Hi,
I have worked few days to fix my problems... and I'm going nowhere.
So, I Need help:
I have o complex Windows Form Application which build dynamic the GUI, from an xml file.
The structure of GUI is very complicated:
A MainForm which contain a splitcontainer
In Panel2 of SplitContainer I have an UserControl =a frame for opened forms inside to app
On each GUI form ai have an complex usercontrol which contain:
a splitcontainer with a DataGridView (ReadOnly) in left and TableLayoutPanel in right
In TableLayoutPanel I have one or more panels (called groups).
In each panel I have
two panels - one with a title, and one with another TableLayoutPanel which contain the controls for editing current record .
The GUI form can have a header and one or more details each zone (header,details) contain same structure: a grid and controls for editings current record, in the structure described .
So, I need to control the flow to next control with tab.:
When the focus is on the last control , next forward tab to select first control in same level (header, or details)
Each control for editing record Inherit a class fieldTemplate
I tried to override ProcessTabKey in Group container:
protected override bool ProcessTabKey( bool forward )
{
if (ActiveControl == null ) return base.ProcessTabKey(forward);
if (!forward && ((fieldTemplate)ActiveControl).IsFirst)
{
lastControl.Select();
return true;
}
if (forward && ActiveControl == lastControl)
{
firstControl.Select();
return true;
}
return base.ProcessTabKey(forward);
}
lastControl - is last control from current zone
firstControl - first editing control in current zone.
Is not working.
I also tried to implement ProcessTabKey on each container which accept this method. No good result.
I think i hard to understand the structure of inheritance of controls.
If I can upload o a screen capture will be simple to understand.
The code is very large and complex...
