  I am using a C1TrueDBGrid (vb.net), and the user can move the cursor to the right of the right-most column and the cursor will turn into a vertical bar with a right arrow. The user can then click and drag to the right and expose columns in the grid that are not visible. How do I prevent this? Is there a setting that prevents the user from having this option?

  On this page, I found it referenced:
  
  https://www.grapecity.com/componentone/docs/win/online-truedbgrid/sizing-splitting.html

  It says,

  “To make the column visible again, the user can point to the right side of the divider of the column that preceded it. The pointer turns into a vertical bar with a right arrow. Dragging the pointer to the right establishes a new column width and sets the column’s Visible property back to True.”

  But, I cannot find anywhere to set any setting to prevent this from happening.

  Please see attached image, and forgive the horrible image! If I tried to take a screen shot, the cursor disappeared. I took this pic with my phone of the vertical bar with arrow cursor in question.

  Any thoughts? Thank you!

  Hi Doug,

  To prevent the customer from showing the hidden columns, you can set the C1DisplayColumn.AllowSizing property to false. Please see the attached sample project for reference.

  c1TrueDBGrid1.Splits[0].DisplayColumns["ColName"].Visible = false;
  c1TrueDBGrid1.Splits[0].DisplayColumns["ColName"].AllowSizing = false;
