Simulate a mouse click in a cell

[Andreas Gfeller]

How can I simulate a mouse click in a cell?
The Background: I have two grid controls in an form. I want to programmatically switch the focused cell from one grid to the other.

I've attached a small sample project: Select a cell in one of the grids and move the cells with the keyborads arrow keys.

When reaching the upper or lower border of a grid, the focus switches to the other grid control.

But there is a problem: When the focus changes, the grid who lost the focus, still shows a dotted frame around the cell. This dotted frame does not appear when you change between the grids by mouse clicks.

How do I avoid this dotted frame?

No ideas?

Hi Andress,

Sorry for delay in replying.

There is a property that sets when the border around the currentcell is shown. Its called ShowCurrentCellBorderBehavior. Depending upon this setting, you can can see a border around the current cell when the grid has focus. You can set HideAlways before the CurrentCell is moved to next Grid and set WhenGridActive when the focus is back to the CurrentGrid. Please refer the modified code for more details.

private void gridControl2_CurrentCellKeyDown(object sender, KeyEventArgs e)
    {
      GridControl grid = sender as GridControl;
      if (grid == null)
        return;

      int row = grid.CurrentCell.RowIndex;
      int col = grid.CurrentCell.ColIndex;

      switch (e.KeyCode)
      {
        case Keys.Up:
          if (row > 1)
            --row;
          else
          {
            this.gridControl1.ShowCurrentCellBorderBehavior = GridShowCurrentCellBorder.WhenGridActive;
            this.gridControl2.ShowCurrentCellBorderBehavior = GridShowCurrentCellBorder.HideAlways;
            gridControl1.CurrentCell.MoveTo(gridControl1.RowCount, col, GridSetCurrentCellOptions.ScrollInView);
            gridControl1.Focus();

          }
          break;

        case Keys.Down:
          if (row < grid.RowCount)
            ++row;
          break;

        case Keys.Left:
          if (col > 1)
            --col;
          break;

        case Keys.Right:
        case Keys.Tab:
          if (col < grid.ColCount)
            ++col;
          break;

        default: return;
      } // switch
      grid.CurrentCell.MoveTo(row, col, GridSetCurrentCellOptions.ScrollInView);
      e.Handled = true;
    }

    private void gridControl1_CurrentCellKeyDown(object sender, KeyEventArgs e)
    {
      GridControl grid = sender as GridControl;
      if (grid == null)
        return;

      int row = grid.CurrentCell.RowIndex;
      int col = grid.CurrentCell.ColIndex;

      switch (e.KeyCode)
      {
        case Keys.Up:
          if (row > 1)
            --row;
          break;

        case Keys.Down:
          if (row < grid.RowCount)
            ++row;
          else
          {
            this.gridControl1.ShowCurrentCellBorderBehavior = GridShowCurrentCellBorder.HideAlways;
            this.gridControl2.ShowCurrentCellBorderBehavior = GridShowCurrentCellBorder.WhenGridActive;
            gridControl2.CurrentCell.MoveTo(1, col, GridSetCurrentCellOptions.ScrollInView);
            gridControl2.Focus();
          }
          break;

        case Keys.Left:
          if (col > 1)
            --col;
          break;

        case Keys.Right:
        case Keys.Tab:
          if (col < grid.ColCount)
            ++col;
          break;

        default: return;
      } // switch
      grid.CurrentCell.MoveTo(row, col, GridSetCurrentCellOptions.ScrollInView);
      e.Handled = true;
    }

Please refer the sample in the below link that illustrates the above.
