RadCheckBoxElement not shown in GridDataCellElement

[QuAzI]

I have table with custom field based on GridDataCellElement.
Now in this field RadLabelElement and two RadButtonElement shown. All OK.
But when I am try to add RadCheckBoxElement - all field will shown empty.

protected override void CreateChildElements()
{
    // ... init elements
    this.Children.Add(radLabel); // ok
    this.Children.Add(radbtnColor); // ok
    this.Children.Add(radbtnFont); // ok
    this.Children.Add(new RadCheckBoxElement()); // GridDataCellElement will shown empty if this line not removed
}

How can I fix it?

Hello,

Thank you for writing.

I was not able to reproduce the observed behavior on my end. For convenience, I prepared a small sample, based on the information that you provided so far and attached it to this thread. Could you please check it and let me know how it differs from your real setup? 

Thank you in advance for your patience and cooperation.
