Environment

Browser: All browsers

Analysis of the Issue

The issue arises due to the way the TimeDurationPicker handles the columns format. When the format is configured as ##, the widget expects the input to be in the format of HH:mm:ss. However, when the user types a value, the widget does not correctly parse the input, resulting in an incorrect display.

Solution

To resolve this issue, you can configure the columns format as HH:mm:ss instead of ##. This will ensure that the user input is displayed correctly.

Example Code

Here is an example of how to configure the columns format as HH:mm:ss:

var timeDurationPicker = $("#timeDurationPicker").kendoTimeDurationPicker({
    columns: [
        {
            format: "HH:mm:ss"
        }
    ]
}).data("kendoTimeDurationPicker");

By configuring the columns format as HH:mm:ss, you can ensure that the user input is displayed correctly without any formatting issues.

To resolve this issue, you can configure the columns format as HH:mm:ss instead of ##.
