I am implementing the Rad Scheduler Control by creating the Appointments through Drag and Drop feature.I implemented a Advance Edit Form where i took two comboboxes with tasks and the BreakTime...
and on the top of the scheduler i took 3 buttons TaskView,BreakView and Shift(appointment)View.
so when ever i click on the button the subject of the appointement should be updated based on the selected one.(say if i clicked on the task view ,the subject field should contain the tasks assigned for that appointment).I tried it writting the code inside the appointment -created event but i am getting the error as "Collection was modified; enumeration may not execute " I dont know the reason why i am gettiing this..
Here is the code i implemented..
protected
void RSchedulerTemplate_OnAppointmentCreated(object sender, AppointmentCreatedEventArgs e)
{
ViewScheduler(
string ViewType);
}
privatevoid ViewScheduler(string ViewType)
{
for (int i = 0; i < DRMSession.DTScheduler.Rows.Count; i++)
{
ShiftDetails sDetails = GetShiftData(DRMSession.DTScheduler.Rows[i]["schedulerid"].ToString());
// assign startOffSet hours and minutes
TimeSpan startTime = TimeSpan.FromTicks(sDetails.startOffset);
TimeSpan endTime = TimeSpan.FromTicks(sDetails.Duration);
TimeSpan startOffSet = new TimeSpan(startTime.Hours, startTime.Minutes, 0);
DateTime startOffSetDate = new DateTime(startOffSet.Ticks);
// assign duration hours and minutes
TimeSpan duration = new TimeSpan(endTime.Hours, endTime.Minutes, 0);
DateTime durationDate = new DateTime(duration.Ticks);
// startOffSet and duration formatting result
string startOffSetResult = startOffSetDate.ToString("hh:mm tt");
string durationResult = durationDate.ToString("hh:mm tt");
string jobGroupName = string.Empty;
foreach (JobGroup jGroup in JobGroups)
{
if (jGroup.Id == sDetails.jobGroupId) {
jobGroupName = jGroup.Name;
break; }
}
switch (ViewType) {
case "Shift":
{
DRMSession.DTScheduler.Rows[i]["name"] = jobGroupName + " # " + startOffSetResult + " - " + durationResult;
}
break;
case "Task":
{
if (sDetails.LstTaskIds.Count > 0)
{
string tasksList = string.Empty;
foreach (Task tsk in Tasks)
{
foreach (int taskId in sDetails.LstTaskIds)
{
if (tsk.Id == taskId)
{
tasksList +=
Environment.NewLine + tsk.Title;
}
}
}
DRMSession.DTScheduler.Rows[i]["name"] = jobGroupName + Environment.NewLine + " # " + startOffSetResult + " - " + durationResult + Environment.NewLine + tasksList;
}
}
break;
case "Break":
{
if (sDetails.LstBreakIds.Count > 0)
{
string breakTypes = string.Empty;
foreach (BreakType bType in BreakType)
{
for (int Cnt = 0; Cnt < sDetails.LstBreakIds.Count; Cnt++)
{
if (sDetails.LstBreakIds[Cnt] == bType.Id)
{
breakTypes +=
Environment.NewLine + bType.Type + "-" + DateTime.Parse(sDetails.LstBreakTime[Cnt].ToString()).TimeOfDay;
}
}
}
DRMSession.DTScheduler.Rows[i]["name"] = jobGroupName + Environment.NewLine + " # " + startOffSetResult + " - " + durationResult + Environment.NewLine + breakTypes;
}
}
break;
}
}
RSchedulerTemplate.DataSource =
DRMSession.DTScheduler;
RSchedulerTemplate.Rebind();
}
protected void btnShiftView_Click(object sender, EventArgs e)
{
ViewType =
"Shift";
ViewScheduler(ViewType);
}
protected void btnTaskView_Click(object sender, EventArgs e)
{
ViewType =
"Task";
ViewScheduler(ViewType);
}
protected void btnBreakView_Click(object sender, EventArgs e)
{
ViewType =
"Break";
ViewScheduler(ViewType);
}
This is a crucial requirement. Appreciate any help in this regard.
