.net - TableLayoutPanel rows & columns at runtime -

im trying build usercontrol contains tablelayoutpanel. in panel need dynamically add 3 columns each having different width , 5 rows shell have same height (20% of tablelayoutpanel's height).

column1 should have absolute width of 20, column2 depending width on content (a textbox .dock = fill) column3 width of 30.

my code:

private sub buildgui()     if rows > 0          tlp.controls.clear()         tlp.columnstyles.clear()         tlp.rowstyles.clear()           if style = styles.adding             tlp.columnstyles.add(new columnstyle(sizetype.absolute, 30))             tlp.columnstyles.add(new columnstyle(sizetype.autosize))             tlp.columnstyles.add(new columnstyle(sizetype.absolute, 20))             tlp.columncount = 3              tlp.rowstyles.add(new rowstyle(sizetype.autosize, 20%))             tlp.rowstyles.add(new rowstyle(sizetype.autosize, 20%))             tlp.rowstyles.add(new rowstyle(sizetype.autosize, 20%))             tlp.rowstyles.add(new rowstyle(sizetype.autosize, 20%))             tlp.rowstyles.add(new rowstyle(sizetype.autosize, 20%))             tlp.rowcount = rows              = 0 rows - 1                 dim l new label                 dim t new textbox                 dim c new checkbox                  l                     .backcolor = color.aqua                     '.dock = dockstyle.fill                     .visible = true                     .borderstyle = windows.forms.borderstyle.fixedsingle                     .font = new font("microsoft sans serif", 11, fontstyle.bold)                 end                 tlp.controls.add(l, 0, i)                  t                     .backcolor = color.beige                     .visible = true                     .multiline = true                     .scrollbars = scrollbars.vertical                     .dock = dockstyle.fill                 end                 tlp.controls.add(t, 1, i)                  c                     .visible = true                     .backcolor = color.brown                 end                 tlp.controls.add(c, 2, i)              next         else          end if      end if 

end sub
