Hi Hiren,

Please try the below code snippet to highlight today's date when filtering.

C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
  {
      if (e.Item is GridFilteringItem)
      {
          foreach (GridColumn col in RadGrid1.Columns)
          {
              if (col.ColumnType == "GridDateTimeColumn")
              {
                  GridFilteringItem filteringItem = (GridFilteringItem)e.Item;
                  RadDatePicker datepicker = (RadDatePicker)filteringItem[col.UniqueName].Controls[0];
                  RadCalendarDay NewDay = new RadCalendarDay();
                  NewDay.Repeatable = RecurringEvents.Today;
                  NewDay.ItemStyle.BackColor = System.Drawing.Color.Red;
                  datepicker.SharedCalendar.SpecialDays.Add(NewDay);
              }
          }
      }
  }

Thanks,

Hello Princy,

Thanks for your reply but unfortunately your solution is not feasible because i need to change in 100 of places


I required global solution. either on CSS or Javascript 

Thanks,

Hi Hiren,

You can use ControlAdapter in your site, that to affects all RadCalendars. In the adapter you can override the load of the control and add the special day.

JavaScript solution will be possible, but will require more scripting, and will be slower in executing in the browser. You can do it by overriding the Telerik.Web.UI.RadCalendar.prototype.initialize. But generally I wouldn't recommend this,

Note that there will be difference between the server and client approach. For example the server can be in different time zone, which means that today in server is tomorrow or yesterday in client.
Also if the clock on the client machine is wrong, it will see wrong highlighted date with the JavaScript approach and correct with the server side approach.

Hi Hiren,

I am attaching an example of ControlAdapter that to apply style for the current day in all calendars of your page. It will work for dynamically added as well, and you don't need to change any existing code.
