Set value when DropDownList is disabled

[Heiko]

I create a disabled DropDownList with the following code:

<kendo-dropdownlist for="FreezeVM.Year" class="form-control"
                    datatextfield="Text"
                    datavaluefield="Value"
                    height="290"
                    enable="false"
                    bind-to="Model.YearList">
</kendo-dropdownlist>




Based on another DropDownList I change the value of this list:

function onTargetTypeChange(e) {
    var targetValue = this.value();
    var currentYear = new Date().getFullYear();
    var yearDrop = $("#FreezeVM\\.Year").data("kendoDropDownList");
    if (targetValue === "6" || targetValue === "7") {
        yearDrop.value(currentYear + 1);
    }
    else {
        yearDrop.value(currentYear);
    };
};

 

The change is reflected on the UI, but not on the underlying Model which still has the old value. As soon as I enable the DropDownList everything works fine. What I expect is that the value gets changed no matter if the dropdown is enabled or disabled.

Hi Heiko,

Based on the provided code, I've tried to reproduce the reported issue but I am unable to do it. 

Attached to my reply you will find a project in which there are two DropDownLists. The first one has values range from 1 to 7 and is enabled. The second one is disabled and has values ranging from 2016 to 2021. Based on the selected item in the first DropDownList, the value of the second one is being changed using the provided onTargetTypeChange function. 

Under the two DropDownLists, there is a button that alerts the current value of the disabled DropDownList directly from its DataSource. Using the provided instruction I am trying to reproduce the reported issue but the value of the disabled DropDownList is being changed and the displayed value is the expected one. 

Can you please modify the attached project in a way the issue you report could be reproduced and send the project back to me? Having the issue reproduced, I will be able to investigate what is triggering it and give a possible solution for the case.

Petar
