Description
When working with the RadDateRangePicker control, it's necessary to validate that the user has selected both a start and an end date. This article demonstrates how to validate the date selection within the RadDateRangePicker control.
This KB article also answers the following questions:
- How can I ensure a user selects both dates in RadDateRangePicker?
- What is the method for validating date selection in RadDateRangePicker?
- How do I prevent form submission without both dates selected in RadDateRangePicker?
Solution
To validate that both the start and end dates are selected in the RadDateRangePicker control, follow these steps:
- Include the DateRangePicker and a Button control in your ASPX page.
<telerik:RadDateRangePicker runat="server" ID="DateRangePicker1" />
<telerik:RadButton RenderMode="Lightweight" runat="server" Text="Save" ID="Button1" OnClientClicked="onClientClicked" />
- Implement the client-side validation logic in JavaScript to check if both dates are selected. If not, display an alert message to the user.
function onClientClicked(sender, args) {
var dateRangePicker = $find("<%= DateRangePicker1.ClientID %>");
var startDate = dateRangePicker.get_startDatePicker().get_selectedDate();
var endDate = dateRangePicker.get_endDatePicker().get_selectedDate();
if (!startDate || !endDate) {
alert("Please select both start and end dates.");
return false;
}
return true;
}
By following these steps, you can effectively ensure that both the start and end dates are selected in the RadDateRangePicker control before proceeding with any further action, such as form submission.
