[Closed] dotnet focus

How come when I click in the input field and being typing it doesn’t appear to actually set focus? I’m assuming its because i have dotnet controls inside other dotnet controls. How do i fix this?

try(destroyDialog ::nameTagToolRO)catch()
rollout nameTagToolRO "NameTag Tool"
(
	local tabStyle = dotNetClass "System.Windows.Forms.TabAppearance"

	dotNetControl uiTabs "TabControl" pos:[0,0]
	
	fn SetLifeTimeControl ctrl = dotNet.setLifeTimeControl ctrl #dotNet

	fn ResizeUI =
	(
		w = nameTagToolRO.width
		h = nameTagToolRO.height
		uiTabs.width = w
		uiTabs.height = h
	)

	fn InitTextbox pos:[0,0] width:0 =
	(
		c = dotNetObject "Textbox"
		c.Location = (dotNetObject "System.Drawing.Point" pos[1] pos[2])
		c.Tag = "resize"
		c.AcceptsTab = True
		c
	)

	fn InitTabs ctrl:unsupplied =
	(
		if ctrl != unsupplied do
		(
			ctrl.TabPages.Clear()
			ctrl.sizeMode = ctrl.sizeMode.fixed	
			ctrl.itemSize = dotnetObject "System.Drawing.Size" 75 25
			ctrl.TabPages.add "Nodes"
			ctrl.TabPages.add "Materials"	
			ctrl.Appearance = tabStyle.buttons
			ResizeUI()

			uiName = InitTextbox pos:[70,37] width:0
			ctrl.TabPages.Item[0].controls.add uiName
		)
	)
	
	on nameTagToolRO open do
	(
		InitTabs ctrl:uiTabs
	)
)
createDialog nameTagToolRO width:400 height:600 style:#(#style_SysMenu, #style_titlebar, #style_minimizebox, #style_resizing)
