Zooming
You can
implement the zoom functionality in the WinForms GridControl by
increasing or decreasing the font size, column widths, and row heights
proportionally.
The following code example illustrates the Zoom down functionality in GridControl on button click.
private void button2_Click(object sender, System.EventArgs e)
{
//down
this.gridControl1.BeginUpdate();
this.gridControl1.BaseStylesMap["Standard"].StyleInfo.Font.Size *= down;
this.gridControl1.DefaultColWidth = (int) (down * this.gridControl1.DefaultColWidth);
this.gridControl1.ColWidths[0] = (int) (down * this.gridControl1.ColWidths[0]);
this.gridControl1.DefaultRowHeight = (int) (down * this.gridControl1.DefaultRowHeight);
this.gridControl1.RowHeights[0] = (int) (down * this.gridControl1.RowHeights[0]);
this.gridControl1.EndUpdate();
this.gridControl1.Refresh();
}Private Sub button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles button2.Click
'down
Me.gridControl1.BeginUpdate()
Me.gridControl1.BaseStylesMap("Standard").StyleInfo.Font.Size *= down
Me.gridControl1.DefaultColWidth = CInt(Fix(down * Me.gridControl1.DefaultColWidth))
Me.gridControl1.ColWidths(0) = CInt(Fix(down * Me.gridControl1.ColWidths(0)))
Me.gridControl1.DefaultRowHeight = CInt(Fix(down * Me.gridControl1.DefaultRowHeight))
Me.gridControl1.RowHeights(0) = CInt(Fix(down * Me.gridControl1.RowHeights(0)))
Me.gridControl1.EndUpdate()
Me.gridControl1.Refresh()
End SubThe following code example illustrates the Zoom up functionality in GridControl on button click.
private void button1_Click(object sender, System.EventArgs e)
{
//up
this.gridControl1.BeginUpdate();
this.gridControl1.BaseStylesMap["Standard"].StyleInfo.Font.Size *= up;
this.gridControl1.DefaultColWidth = (int) (up * this.gridControl1.DefaultColWidth);
this.gridControl1.ColWidths[0] = (int) (up * this.gridControl1.ColWidths[0]);
this.gridControl1.DefaultRowHeight = (int) (up * this.gridControl1.DefaultRowHeight);
this.gridControl1.RowHeights[0] = (int) (up * this.gridControl1.RowHeights[0]);
this.gridControl1.EndUpdate();
this.gridControl1.Refresh();
}Private Sub button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles button1.Click
'up
Me.gridControl1.BeginUpdate()
Me.gridControl1.BaseStylesMap("Standard").StyleInfo.Font.Size *= up
Me.gridControl1.DefaultColWidth = CInt(Fix(up * Me.gridControl1.DefaultColWidth))
Me.gridControl1.ColWidths(0) = CInt(Fix(up * Me.gridControl1.ColWidths(0)))
Me.gridControl1.DefaultRowHeight = CInt(Fix(up * Me.gridControl1.DefaultRowHeight))
Me.gridControl1.RowHeights(0) = CInt(Fix(up * Me.gridControl1.RowHeights(0)))
Me.gridControl1.EndUpdate()
Me.gridControl1.Refresh()
End SubThe following
