Can I Use RequiredFieldValidator inside a repeater ?

[bhavesh]

Hello,

I use a repeater to display "Name" and "Order". I hope that users can
change
the "Order" field from the browser. And, if they input invalid value
(such
as string) in the "Order" field, I hope the validator control can alert

them. Can I do this with repeater? Or I should use other webcontrol?


Thanks,
Simon

Repeaters are read only interfaces and don't have a mechanism to switch them
from read only view into edit view (templates). If that is what you need,
you should consider a DataList or a DataGrid.

RequiredFieldValidators won't check the data to see if it is a string, it
will only check to see if there is *some* data. If you need the field to be
required AND you need it to be a specific data type, then you'll need 2
validators (a RequiredFieldValidator and a RangeValidator) associated with
the one input field.

Lastly, yes, you can nest validators inside of DataList and DataGrid
controls (as mentioned you wouldn't put them into Repeaters since repeaters
aren't for data input).
