Ajax Calendar Extender

Question

User-1664485818 posted

Hi folks, is it possible to set the calendar to display advance dates only i.e. 2 days from present date.

Example if today’s date was 04/10/2014, the calendar would only display dates from 07/10/2014 onwards. Calendar code below;

<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server"></asp:ToolkitScriptManager>
    <asp:CalendarExtender ID="CalendarExtender2" TargetControlID="txtFittingDate" runat="server" Format="dd/MM/yyyy"></asp:CalendarExtender>

Hello,

Override the Init event of page class and set the Minimum and Maximum date for the calender:

protected internal override void OnInit(EventArgs e)
{
    base.OnInit(e);
     //set the validator min and max values
        this.CalenderExtender2.MinimumValue = DateTime.Today.Date.AddDays(2).ToShortDateString();               
}

Pasted your code, receiving the following error message;

Error AjaxControlToolkit.CalendarExtender' does not contain a definition for 'MinimumValue' and no extension method 'MinimumValue' accepting a first argument of type 'AjaxControlToolkit.CalendarExtender' could be found (are you missing a using directive or an assembly reference?)

Oh sorry .. the property is StartDate.

protected internal override void OnInit(EventArgs e)
{
    base.OnInit(e);
     //set the validator min and max values
        this.CalenderExtender2.StartDate=DateTime.Today.AddDays(2).ToShortDateString();               
}

        this.CalenderExtender2.StartDate=DateTime.Today.AddDays(2);

Hi Ashim, my fault your code is working fine, is it possible to hide these dates from the calendar picker? At the moment the dates are just scored out

is it possible to hide these dates from the calendar picker?

I think its possible , try to change the css for invalid dates like below:

.cal_Calendar .ajax__calendar_invalid .ajax__calendar_day
  /* Add class for your Invalid dates*/
  {
      display:none; // this should work , however its untested
  }
