Winform Button focus on Up/Down Arrow key

In Winform  I have 2 buttons . When I use the UP/Down arrow key it chnages the focus from one button to other.I want to disable this button focus chnage when Up/Down arrow key is hit on the keyboard.

Instead I wanted to us for Datagrid. So I worte the following code for Scrolling the Grid.
protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
                        
      switch (keyData)
      {
            case Keys.Down:
                 SelectNextGridRow();
                 break;
            case Keys.Up:
                   SelectNextGridRow();
                 break;
      }
      return base.ProcessCmdKey(ref msg, keyData);
}

The focus on buttons also keeps chnaging when I hit Up/Down Key. How do I disable this?

This part:

    return base.ProcessCmdKey(ref msg, keyData);

causes the default action for the keys to be processed.

If you don't want something to happen for certain keys then you need to NOT call the above line of code for them...

Idle_Mind is correct, just move the return to the default action and you should be OK.

protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
                       
      switch (keyData)
      {
            case Keys.Down:
                 SelectNextGridRow();
            case Keys.Up:
                   SelectNextGridRow();
            default:
                   return base.ProcessCmdKey(ref msg, keyData);
      }
}

Forgot the return statement for the up down keys...

protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
                       
      switch (keyData)
      {
            case Keys.Down:
                 SelectNextGridRow();
                 return true;
            case Keys.Up:
                   SelectNextGridRow();
                   return true;
            default:
                   return base.ProcessCmdKey(ref msg, keyData);
      }
}
