InlineEdit - Need To Select Dropdown Twice to Capture Value

[SOLOMON]

I have a simple grid where only a Boolean field needs to be change. The Boolean allows for nulls. When I edit the row, I have to select the value twice before it holds the value, then save. The selected value saves fine. Its just having to select it twice to get it to stick. Has anyone seen this behavior before?

Hi Solomon,

Basically editing of nullable boolean using checkbox is invalid configuration as the checkbox have only two states. That why a DropDownList should be used instead - please check the example editor below:

{
    title: "Is Completed",
    field: "IsCompleted",
    encoded: true,
    editor: '<select class="list-box tri-state" id="IsCompleted" name="IsCompleted">' +
        '<option selected="selected" value="">Not Set</option>' +
        '<option value="true">True</option>' +
        '<option value="false">False</option>' +
        '</select>'
}
