[CLOSED] Optional Combobox Invalid Value MarkInvalid

[vzx]

Hi all,

I have a combobox in a formpanel and assume that it has two values.
- "ABC"
- "DEF"

 <ext:ComboBox ID="combo" runat="server" StoreID="Store1" QueryMode="Local" EnableRegEx="true" AllowBlank="true">

When I write "GH" in combo, it can't find any value but combo mark itself as valid, and it changes the form as valid. But I want that combo marks itself as invalid and so formpanel will be invalid, like forceselection = "true" property. I can't set forceselection as true, because combo is optional.

I searched forums, but I can't find a solution that fits my problem. Please can you help me.

Thanks,
Vzx

Hi @Vzx,

I can suggest to try with a custom Validator.

To validate a blank value with your custom Validator, you will need to set ValidateBlank to true.
