This question was asked by 3 to 4 youtube subscribers of my channel. There are several reasons or situations in real time, where we need to navigate to a specific month and an year in an asp.net calendar control. For example, if the date of birth of a person is in the year 1960, we may have to click on the calendar control several times to navigate to that year.
Let's see, how to skip months and years, so that the dates that are too far in the past or future can be easily selected. To achieve this
For the HTML and code samples used in the demo please visit my blog at the following link
http://csharp-video-tutorials.blogspot.com/2013/01/navigating-to-specific-month-and-year.html
Copy and paste the following code in the code-behind file
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
LoadYears();
LoadMonths();
}
}
private void LoadMonths()
{
DataSet dsMonths new DataSet();
dsMonths.ReadXml(Server.MapPath("~/Data/Months.xml"));
DropDownList2.DataTextField "Name";
DropDownList2.DataValueField "Number";
DropDownList2.DataSource dsMonths;
DropDownList2.DataBind();
}
private void LoadYears()
{
DataSet dsYears new DataSet();
dsYears.ReadXml(Server.MapPath("~/Data/Years.xml"));
DropDownList1.DataTextField "Number";
DropDownList1.DataValueField "Number";
DropDownList1.DataSource dsYears;
DropDownList1.DataBind();
}
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
int year Convert.ToInt16(DropDownList1.SelectedValue);
int month Convert.ToInt16(DropDownList2.SelectedValue);
Calendar1.VisibleDate new DateTime(year, month, 1);
Calendar1.SelectedDate new DateTime(year, month, 1);
}
protected void DropDownList2_SelectedIndexChanged(object sender, EventArgs e)
{
int year Convert.ToInt16(DropDownList1.SelectedValue);
int month Convert.ToInt16(DropDownList2.SelectedValue);
Calendar1.VisibleDate new DateTime(year, month, 1);
Calendar1.SelectedDate new DateTime(year, month, 1);
}
protected void Button1_Click(object sender, EventArgs e)
{
Response.Write(Calendar1.SelectedDate.ToShortDateString());
}
At this point, run the project and you should be able to skip to any month and year in an asp.net calendar control. This code can be encapsulated in an user control, and reused anywhere in the entire project.
