I want to create a radio button list in zebble.net to force the user to select 1 option among 3 choices of opt1 to opt3 enter image description here

I have checked the documentation and found only the checkbox and optionsList controls.

So I deduct that something like below code can render a radioButtonList 

  <OptionsList Id="MyOptionsList" Direction="Horizontal" MultiSelect="false">    
    <CheckBox Id="MyCheckBox1" Checked="false"> </CheckBox>
    <CheckBox Id="MyCheckBox2" Checked="false"> </CheckBox>
    <CheckBox Id="MyCheckBox3" Checked="false"> </CheckBox>
    </OptionsList>

but it will render nothing.what is the problem and how this OptionsList works i could not find any sample showing working usages of this control.

I appreciate can show how this can be done in zebble or in pure xamarin Forms.

Based on the documentation, you should use the DataSource property of the OptionsList.

So remove the nested CheckBox elements, and instead set the DataSource property:

<OptionsList Id="MyOptionsList" Direction="Horizontal"
     MultiSelect="false" DataSource="GetMyOptions()" />

Then in your code behind file, add the method to return the data:

IEnumerable<string> GetMyOptions()
{
    return new [] { "My Option1", "My Option2", "My Option3" };
}

  • thanks,in the documentation it is written "You can bind" and you are saying "you should use" the DataSource and that was a little misleading for me and thought it is optional and I also can insert the items in the markup because there were no compile errors, but it seems that it is in fact a must – Iman Apr 10 '17 at 07:29
