A DropDownList cannot have multiple items selected.
Dear Guys,
I have created a web user control with a function which populates dates,
this is code I have written
private void Page_Load(object sender, System.EventArgs e)
{
// Put user code to initialize the page here
int CurrentDateYear = DateTime.Now.Year;
int CurrentDateMonth = DateTime.Now.Month;
int CurrentDateDay = DateTime.Now.Day;
DateTime LastMonthDate = DateTime.Today.AddMonths(-1);
int LastMonthDateYear = LastMonthDate.Year;
int LastMonthDateMonth = LastMonthDate.Month;
int LastMonthDateDay = LastMonthDate.Day;
this.PopulateBeginYear(LastMonthDateYear);
this.PopulateBeginMonth(LastMonthDateMonth);
this.PopulateBeginDay(LastMonthDateDay);
this.PopulateEndYear(CurrentDateYear);
this.PopulateEndMonth(CurrentDateMonth);
this.PopulateEndDay(CurrentDateDay);
}
public void PopulateBeginYear(int ly)
{
int max = DateTime.Now.Year + 5;
for(int i = 2000; i <= max; i++)
{
ListItem item = new ListItem(i.ToString(),i.ToString());
item.Selected = (i == ly);
ddlBeginYear.Items.Add(item);
}
}
public void PopulateBeginMonth(int lm)
{
for(int i = 1; i <= 12; i++)
{
ListItem item = new ListItem(i.ToString(),i.ToString());
item.Selected = (i == lm);
ddlBeginMonth.Items.Add(item);
}
}
public void PopulateBeginDay(int ld)
{
for(int i= 1; i<=31; i++)
{
ListItem item = new ListItem(i.ToString(),i.ToString());
item.Selected = (i == ld);
ddlBeginDay.Items.Add(item);
}
}
public void PopulateEndYear(int cy)
{
int max = DateTime.Now.Year + 5;
for(int i = 2000; i <= max; i++)
{
ListItem item = new ListItem(i.ToString(),i.ToString());
item.Selected = (i == cy);
ddlEndYear.Items.Add(item);
}
}
public void PopulateEndMonth(int cm)
{
for(int i = 1; i <= 12; i++)
{
ListItem item = new ListItem(i.ToString(),i.ToString());
item.Selected = (i == cm);
ddlEndMonth.Items.Add(item);
}
}
public void PopulateEndDay(int cd)
{
for(int i= 1; i<=31; i++)
{
ListItem item = new ListItem(i.ToString(),i.ToString());
item.Selected = (i == cd);
ddlEndDay.Items.Add(item);
}
}
public DateTime StartDate
{
get
{
return new DateTime(Convert.ToInt16(ddlBeginYear.SelectedItem.Value),Convert.ToInt16(ddlBeginMonth.SelectedItem .Value),Convert.ToInt16(ddlBeginDay.SelectedItem.Value));
}
}
public DateTime EndDate
{
get
{
return new DateTime(Convert.ToInt16(ddlEndYear.SelectedItem.Value),Convert.ToInt16(ddlEndMonth.SelectedItem.Val ue),Convert.ToInt16(ddlEndDay.SelectedItem.Value));
}
}
Then I used this usercontrol in another aspx form, then i got it populated the dates for some reason it gives me some wired error
