hi guys, this is either a bug or a mis-configuration on my behalf.
i have a radio button list on an ADD screen with two options on it
0 | Incident
1 | Near Hit
it's set up as per below;
when i run the page, if i select the Near Hit option, all works well
however when i hit the Incident option, the validator triggers
the validator is configured with the SCRUD generator, so it's out of the box config here
any ideas to not trigger the validator on 0 | Incident ?
Hi @TMRGlobal,
Try setting the DefaultValue property of the validator to 0.
Thanks @korchev
i have set the default value to 0 (integer)
the page load looks okay, selecting the "near hit" value looks good, changing back to "incident" triggers the validator though
so the state was load --> incident selected, select Near hit (good), select Incident (validator triggered)
the only variance is that an incident has a value of 0 while near hit has a value of 1
i'll change the underlying integer and see if this impacts it
okay confirmed
when changed values from 0|Incident to 1|Incident the validator worked as expected
from a value perspective, 0 is a perfectly acceptable value, it's not NULL, i think this is a defect in the validator which thinks a 0 int is NULL
for exampole you can use a int to reflect a boolean state 0 = false 1 = true in the above configuration, this validator would behave incorrectly
The validator doesn't think anything. It's implementation is quite trivial to be honest: radzen-blazor/Radzen.Blazor/RadzenRequiredValidator.cs at master · radzenhq/radzen-blazor · GitHub
And here is how HasValue of RadzenRadioButtonList is implemented: radzen-blazor/Radzen.Blazor/FormComponent.cs at master · radzenhq/radzen-blazor · GitHub
The default value depends on the type of the property.
