• Batikit C# Windows Forms ListBox - Aligning Text to the right

  I am trying to align text in a C# Windows Listbox to the right and I can not seem to figure this one out. In MSDN I saw this HorizontalAlignment.Center but it is not an option I can find for the ListBox. Can anyone help me on this Thank you. You can use that example for the owner-drawn listbox.

• Rafael Mores resize the datagrids?

  I have two datagrids on a form. Sometimes the top one contains for rows, sometimes the bottom one. Is there a way that the user can grab the bottom of the top datagrid and move it up so that it becomes a smaller window, then grab the top of the bottom datagrid and slide it up so it becomes a larger window Thanks If you're using .NET 2.0, the SplitContainer would be the right tool for the job. Put it on the form, set its Dock property to Fill an Orientation property to Horizontal. Put the first grid in the upper panel and second grid in lower one. Set both grid's Dock panel to Fill. If you're using .NET 1.x, the Splitter control will help you achieve a similar solution. Just dock it between both grids. ...Show All
