Customize the MonthCalendarAdv
Users can customize the font style of specific dates as bold. This can be achieved by handling the DateQueryCellInfo event. Here, we have added the required bold dates to the BoldDateTime list, then checked its value against the MonthCalendarAdv date cell value in the DateQueryCellInfo event. If the date value matches, the font style of the corresponding date is changed to bold. The following code demonstrates the same.
C#
private List<DateTime> BoldDateTime = new List<DateTime>();
//Raise the event for Date cell customization
this.monthCalendarAdv1.DateCellQueryInfo += MonthCalendarAdv1_DateCellQueryInfo;
//Add Bold date
BoldDateTime.Add(DateTime.Now.AddDays(+1));
BoldDateTime.Add(DateTime.Now.AddDays(+2));
BoldDateTime.Add(DateTime.Now.AddDays(+3));
BoldDateTime.Add(DateTime.Now.AddDays(-1));
BoldDateTime.Add(DateTime.Now.AddDays(-2));
private void MonthCalendarAdv1_DateCellQueryInfo(object sender, Syncfusion.Windows.Forms.Tools.DateCellQueryInfoEventArgs e)
{
/// <summary>
/// check date value is equal for added bold date value
/// If yes, it shows the date value as bold
/// </summary>
if(e.DateValue != null && (!BoldDateTime.Contains(Convert.ToDateTime(e.DateValue))))
{
for(int i = 0; i < BoldDateTime.Count; i++)
{
if(this.BoldDateTime[i].Date.ToString() == e.DateValue.ToString())
{
//enable Bold
e.Style.Font.Bold = true;
}
}
}
}VB
Private BoldDateTime As New List(Of Date)()
'Raise the event for Date cell customization
AddHandler Me.monthCalendarAdv1.DateCellQueryInfo, AddressOf MonthCalendarAdv1_DateCellQueryInfo
'Add Bold date
BoldDateTime.Add(Date.Now.AddDays(+1))
BoldDateTime.Add(Date.Now.AddDays(+2))
BoldDateTime.Add(Date.Now.AddDays(+3))
BoldDateTime.Add(Date.Now.AddDays(-1))
BoldDateTime.Add(Date.Now.AddDays(-2))
Private Sub MonthCalendarAdv1_DateCellQueryInfo(ByVal sender As Object, ByVal e As Syncfusion.Windows.Forms.Tools.DateCellQueryInfoEventArgs)
''' <summary>
''' check date value is equal for added bold date value
''' If yes, it shows the date value as bold
''' </summary>
If e.DateValue IsNot Nothing AndAlso (Not BoldDateTime.Contains(Convert.ToDateTime(e.DateValue))) Then
For i As Integer = 0 To BoldDateTime.Count - 1
If Me.BoldDateTime(i).Date.ToString() = e.DateValue.ToString() Then
'enable Bold
e.Style.Font.Bold = True
End If
Next i
End If
End Sub
