custom validator problem
-
I have a dropdown list with some options and then some textboxes. If optionA is selected from the dropdown a value MUST be entered into the textbox1. If any other option is selected from the dropdown, it is OK for textbox1 to be empty. I am trying to use a custom validator to accomplish this, but whenever i click the submit button is just skips over the code in the ServerValidate function for the custom validator. Anyone have any ideas as to why this is occurring? THanks Cav "Nothing is at last sacred, but the integrity of your own mind."

Hi Cav. Can you post enough of the code for us to get a better idea of what's happening?

OnClick event for the submit button just has a If Page.IsValid then // other code here End this is the Custom Validator Validate event Code (just checking to see if the dropdown is a certain value.. if so, sets the IsValid to T or F): Private Sub cvVendor_ServerValidate(ByVal source As System.Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs) Handles cvVendor.ServerValidate If (drpOpCode.SelectedItem.Value = "CORPORATE") OrElse (drpOpCode.SelectedItem.Value = "DIVISION") Then If txtVendor.Text = "" Then args.IsValid = False End If Else args.IsValid = True End If End Sub When I run the program, it never does into this code... cant figure out why... My required field validator will work, but the Custom Validator will not. Skips right over it. Thanks Cav "Nothing is at last sacred, but the integrity of your own mind."

Hi Cav. Is it possible you haven't set the
ControlToValidateproperty? Can you list the attribute values at work for this control? -

Hmmm... I'm at a loss. I was initially thinking that maybe you needed to set
OnServerValidate="cvVendor_ServerValidation"then I noticed you're using the Handles keyword... I'm really not sure why this wouldn't be firing under the circumstances. Do you know for sure the code isn't getting called (i.e. are you using Trace.Write or breakpoints to verify this?) Since you're not using a client validation function, try settingEnableClientScriptto false and see if that does anything. -

EnableClientScript to false doesnt do anything either... the location of the function shouldnt matter, right? (ie. above/below the submit_btnOnClick event, right)?

Yea, the location shouldn't matter. Just for kicks, try setting the
OnServerValidateattribute inline within the asp:... tag and remove theHandleskeyword from your function. I just read a thread on a google search which sounded very similar to what you're describing; the author indicated the function worked when assigned inline as an attribute but wasn't working otherwise. -

It appears it will run if I have text actually in the textbox, but when the textbox is blank it will not... Will Custom Validators not work with empty textboxes?

Perhaps this is a bug?

It is not a bug. Custom validators when assigned to a text box only go off when there is text in the control. What you want to do is make sure that the
ControlToValidateis NOT set. I use custom validators to validate many different controls at once. Also make sure the the button has theCausesValidationproperty set to true. If you are still having some problems, I can send you my validation code. -

If you are still having some problems, I can send you my validation code.So if I keep the control to Validate NOT set and the Causes Validation set to true, I will then be able to have a conditional statement saying: If X is chosen from the dropdown Then there HAS to be something in the textbox Else it is OK to have nothing in textbox ?
