I have an MDI parent form on which I placed a left-docked treeview with the docking manager. Now I want to open a MDI child form, which fits in the remaining client area (the area between the right border of the docked control and the right border of the MDI parent form).
But if I retrieve the client size from the "ClientSize" property of the parent form, I don''t get the right width). Is there a way to get the right client size?
I''m using version 126.96.36.199.

Do you wish to display the MDI child form as a tabbed MDI ? If so, the tabbed MDI child automatically fills the space available on the parent form. You would have to only host an instance of the TabbedMDIManager within the parent form for this purpose, and no calculation of the client area would be required. Please let me know about it. We appreciate your cooperation.

No, I don''t want to display it as a TabbedMDI. I only want to display a normal MDI child form, non-maximized, in the remaining client area of the MDI parent form and fit the size of the child form to the size of the client area.
But I can''t do:
ChildForm.width = ParentForm.ClientSize.Width
Because the width (or height) of the ClientSize includes the width of the docked controls.

An easy way to find out the vacant client area of the form is to drop a DockingClientPanel onto the main form and setting its SizeToFit property to true. The DockingClientPanel resizes itself to fill the entire vacant space. Now the dimensions of the DockingClientPanel will give you the bounds of the vacant space. Remove this DockingClientPanel from the main form once the bounds are got. I have created a sample_application which illustrates this and have attached it here. Please refer to it and let me know if this meets your requirements.

Thanks for the sample. But that doesn''t work because the MDI parent is already set to MDI container and therefore you can''t set docking style to "fill".
But I did it another way: I took the clientsize and subtracted the widths, heights of the menubars, the toolbars, the statusbar, and the docked controls - including the borders.
Was a lot of work but it works.

Thanks for the update. Please refer to the code snippet taken from my sample :
childSize = this.dockingClientPanel1.Size;
// remove the DockingClientpanel after getting the bounds
// set to true only after dockingClientPanel1 is removed
this.IsMdiContainer = true;
mdichild = new Form();
mdichild.Text = "MDI Child Form";
// 4 pixels have to be deducted from the width and height to account
// for the width of the right and lower borders of the main form
mdichild.Size = new Size(childSize.Width-4, childSize.Height-4);
mdichild.MdiParent = this;
The main form''s IsMdiContainer property is set to false in the designer initially. Hence it is possible to to set the DockingClientPanel''s SizeToFit property to true. IsMdiContainer property is set to true in code only after the DockingClientPanel has been removed from the form. However, we are glad that you could workaround this problem using another approach. Please let me know if you need any other information. We appreciate your interest in Syncfusion products.
