How to increment/decrement the date in DateTimePickerAdv using up/down arrow keys?

Platform: WinForms |
Control: DateTimePickerAdv |
Published Date: April 30, 2011 |

It is possible to add custom LegendItem to the Legend instead of the automated Legend items. For this we have to use the event Legend.FilterItems of the chartControl. This event is raised before the legend items are rendered.

Here is the code snippet.

C#

private void Legend_FilterItems(object sender, ChartLegendFilterItemsEventArgs e)

{

e.Items.Clear();

ChartLegendItemsCollection item = new ChartLegendItemsCollection();

LegendItem l = new LegendItem();

LegendItem l1 = new LegendItem();

l.ItemStyle.BorderColor=Color.Black;

l.Text="Test1";

l1.ItemStyle.BorderColor = Color.Blue;

l1.Text = "Test2";

item.Add(l);

item.Add(l1);

e.Items = item;

}

Please refer the sample that illustrates this:

ChartLegend

Using up/down arrow keys we can increment/decrement the date. This can be acheived by overriding ProcessCmdKey() method of DateTimePickerAdv.

C#

protected override bool ProcessCmdKey(ref System.Windows.Forms.Message msg,

System.Windows.Forms.Keys keyData)

{

if (keyData == System.Windows.Forms.Keys.Up)

{

this.Value = this.Value.AddDays(1);

return true;

}

else if (keyData == System.Windows.Forms.Keys.Down)

{

this.Value = this.Value.AddDays(-1);

return true;

}

else

{

return base.ProcessCmdKey(ref msg, keyData);

}

}

VB

Protected Overrides Function ProcessCmdKey(ByRef msg As

System.Windows.Forms.Message, ByVal keyData As System.Windows.Forms.Keys) As

Boolean

If keyData = System.Windows.Forms.Keys.Up Then

Me.Value = Me.Value.AddDays(1)

Return True

ElseIf keyData = System.Windows.Forms.Keys.Down Then

Me.Value = Me.Value.AddDays(-1)

Return True

Else

Return MyBase.ProcessCmdKey(msg, keyData)

End If

End Function
