[Smart law developer]

hi. I want to select a specific date from source code in the scheduler;
I looked for various properties but couldn't solve them;
my example code)         private void btnToday_Click(object sender, EventArgs e)
        {
            //scdCtrl.Calendar.SelectedDates.Clear();
            scdCtrl.Calendar.DateValue = DateTime.Now; // 2019-08-08
            scdCtrl.GetScheduleHost().Calendar.DateValue = DateTime.Now;
        }         private void Calendar_DateValueChanged(object sender, EventArgs e)
        {
            DateTime firstSelectedTime = scdCtrl.Calendar.SelectedDates[0];     // ========> this date : 2019-09-01, i want "2019-08-08"

            SetViewRangeOfCalendar(firstSelectedTime.Year, firstSelectedTime.Month);

Hi Smart, 

 

Thanks for using Syncfusion product.  

 

To move the selection programmatically, you can use the CurrentCell.MoveTo method after initialize the date value. Please refer the following code example and the sample.  

 

this.scheduleControl1.Calendar.DateValue = new DateTime(2019, 9, 8); 

this.scheduleControl1.Appearance.MonthShowFullWeek = true; 

this.scheduleControl1.GetScheduleHost().CurrentCell.MoveTo(2, 7); 

 

Sample: https://www.syncfusion.com/downloads/support/forum/146541/ze/Schedule_Sample-1030468972  

 

Please refer the below screen shot where the second row and seventh column is selected. 

 

 

 

In this above attached sample, MonthShowFullWeek property has enabled. If you have disabled this property, week days are covered by two rows. So, if you move to second row you could use the following code example.  

 

this.scheduleControl1.GetScheduleHost().CurrentCell.MoveTo(4, 7); 

 

Please refer the below forum for your reference. 

https://www.syncfusion.com/forums/141759/how-can-i-click-specific-date-on-scheculecontrol-programmatically 

 

Note:  

To access the CurrentCell property, you could attach the Syncfusion.Grid.Windows.dll in your project. 

 

Let us know whether this helps also if you need any further assistance on this.

The sample you sent does not change to the date I specified.
What I need is the scheduler grid to change to the date I entered.

[Smart law developer]

This works fine when you run the application, but if you change to a specific date during execution, the scheduler's date does not change to the desired date.

I attached the example project to the attached file,
I explained in screenshots what I needed.

Please solve.

Hi Smart, 

 

Thanks for your update. 

 

We have checked your requirements and modified the sample based on your scenarios. Please find the attached sample and let us know if you have any other queries. 

 

1. Code to update the month view and set the focus to selected date: 

private void btnGoto_Click(object sender, EventArgs e) 

{          

    DateTime date = this.dateTimePicker1.Value; 

    int monthDiff = date.Month - this.scheduleControl1.Calendar.DateValue.Month; 

    this.scheduleControl1.Calendar.DateValue = date; 

    this.scheduleControl1.Calendar.AdjustSelectionsByMonth(monthDiff > 0 ? monthDiff - 1 : monthDiff + 1); 

    this.scheduleControl1.ResetProvider(this.scheduleControl1.ScheduleType); 

    var method = this.scheduleControl1.GetScheduleHost().GetType().GetMethod("SetCurrentCellInView", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic); 

   if (method != null) 

    { 

        this.scheduleControl1.GetScheduleHost().Model.ResetCurrentCellInfo(); 

        method.Invoke(this.scheduleControl1.GetScheduleHost(), new object[] { date }); 

    } 

} 

 

2. Code to update the current month and set focus in NavigationPanel calendar: 

scheduleControl1.Calendar.CalenderGrid.QueryCellInfo += CalenderGrid_QueryCellInfo1; 

 

private void CalenderGrid_QueryCellInfo1(object sender, Syncfusion.Windows.Forms.Grid.GridQueryCellInfoEventArgs e) 

{ 

    DateTime day = this.dateTimePicker1.Value; 

    DateTime isdate; 

    if (!string.IsNullOrEmpty(e.Style.CellValue.ToString()) && DateTime.TryParse(e.Style.CellValue.ToString(),out isdate) && 

        isdate == day) 

    { 

        e.Style.BackColor = this.scheduleControl1.Appearance.NavigationCalendarTodayBackColor; 

        e.Style.TextColor = this.scheduleControl1.Appearance.NavigationCalendarTodayTextColor; 

    } 

}

Thank you for the sample you sent us.
When I press the "Go" button in that sample, it sometimes moves to that date, but most attempts do not move to the date indicated by the datetimepicker.
Attach the sample you sent me, and attach the video I played.
Please debug;

            if (this.dateTimePicker1.Value != this.scheduleControl1.Calendar.DateValue)

            {

                DateTime date = this.dateTimePicker1.Value;

                int monthDiff = ((date.Year - this.scheduleControl1.Calendar.DateValue.Year) * 12) + date.Month - this.scheduleControl1.Calendar.DateValue.Month;

                this.scheduleControl1.Calendar.DateValue = date;

                this.scheduleControl1.Calendar.AdjustSelectionsByMonth(monthDiff > 0 ? monthDiff - 1 : monthDiff + 1);

                var method = this.scheduleControl1.GetScheduleHost().GetType().GetMethod("SetCurrentCellInView", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);

Hi;
I write after a long time.
I couldn't do scheduler coding because of other urgent work.
I tested it with the sample code you sent me last.
The conclusion is not correct.
Attach a video.
It should be coded in detail.
Thank you. ps. my email address : "kim" [email protected]

Hi Smart, 

 

Thanks for your update. 

 

We could reproduce the issue at our end and we are working on this with high priority. We need some more time to validate the use case at our end and we will update you the proper details on 13^th September, 2019.

Hi Smart, 

 

Thanks for your patience. 

 

We have analyzed the reported use case at our end with the sample and it occurred due to the AdjustSelectionsByMonth() method was not updated properly when the DateValue is changed manually through the button click. In order to overcome this use case, the label of header text can be updated properly by using the AdjustSelectionsByMonth() method. We have modified the sample based on your requirement and please make use of the below code and modified sample. 

 

Code example 

 

private void Calendar_DateValueChanged(object sender, EventArgs e) 

{ 

        DateTime firstSelectedTime = scheduleControl1.Calendar.SelectedDates[0]; 

    SetViewRangeOfCalendar(firstSelectedTime.Year, firstSelectedTime.Month); 

    DateSelections SelectedDates = scheduleControl1.Calendar.SelectedDates; 

    //To update the headertext label 

    if (SelectedDates[SelectedDates.Count - 1] > scheduleControl1.Calendar.BottomRightDate.AddDays(-1)) 

    { 

        this.scheduleControl1.Calendar.AdjustSelectionsByMonth(-1); 

    } 

}
