Default Programmatic Validation

Hi All

I wonder if anyone has tackled something similar…

I have a form which consists of several columns and several rows each cell having its own text field presented in a tabular format. What I am looking to achieve is that if a row has been part completed then for the remainder fields of that row to become requiredfield validated. Plus on the other hand if a particular row hasn’t been completed for the requiredfield validator to become disabled.

Does anyone have any ideas how I would go about this?

Many thanks

Rit

Hi Rit,

I am not sure I understand the problem. Can you elaborate a bit? Maybe give an example?

Hi Imar

In a nutshell, is their a way of enabling/ disabling validation on individual controls depending on whether certain other controls have been inputted into.

e.g.
After selecting the submit button...

If textbox1.Text.length > 0 Then
RequiredFieldValidatortextbox2.Enable
End If

... that sort of thing in theory.

In theory *and* in practice (almost)... The BaseValidator control (the the other validators inherit from) has an Enabled property.

http://msdn.microsoft.com/library/de...abledtopic.asp

You can set it to True or False, depending on the requirements.

Not sure if it applies to your situation, but you could also take a look at the ValidationGroup property: http://msdn2.microsoft.com/en-us/library/system.web.ui.webcontrols.basevalidator.validation group(VS.80).aspx that allows you to group validators and other controls together. This allows you to group, for example, an entire row, so a button in 1 row has no influence on validators in other rows....

HtH,

Imar
