Dock control to other one in WinForms

Question

I have got MainForm with TabPage. On TabPage i have got three groupboxes next to one another. First is docked to left top, third to right top. everything is ok but if i maximize window , center textbox goes to bad position (is hide behing first groupbox) How dock this one to stay always between first and third groupbox?

Answer 1

You can accomplish this by using the Dock properties OR the anchor properties. Adding the groups boxes so they are ordered left to right:

Using the Dock properties:

`groupBox1.Dock = left`
`groupBox3.Dock = right`
`groupbox2.Dock = center`

Using the Anchor properties:

`groupBox1.Anchor = Top, Left`
`groupBox3.Anchor = Top, Right`
`groupbox2.Anchor = Top, Left, Right`

EDIT: In either case the center groupBox (groupBox2) should adjust to fill the space between the two outer groupboxes (groupBox1 and groupBox3)
