Question

Why doesn't my javascript code I disable a required field validator?

Asked by: cylikon

I have an OnClientClick assigned to a javascript function that "disables" the validation when a certain button is clicked.

I have this button within a FormView:

<asp:Button ID="btnSaveAndExitTop" runat="server" Text="Save & Exit" OnClick="btnSave_Click" style="margin-right:10px;" CssClass="clsFlatButton2" OnClientClick="javascript: DisableValidators();"/>

This is the javascript to disable all the validators on the page:

 function DisableValidators()
{        
    for(var i=0;i< Page_Validators.length;i++)
    {            
        ValidatorEnable(Page_Validators[i], false)
    }
}

The javascript fires.  When I step through the javascript I can see the enabled element of the validator turn to false but the page valiation still fires and the errors are still displayed.

What am I doing wrong here?

In your validator you might need to check if the element is enabled


if (!element.disabled){
    //Perform validation
}

Do you mean the element that the validator is trying to validate?  If so, then yes.  All the controls that are being "validated" are enabled.

At present, all the validators are enabled when this code is called on the OnClientClick event.  

Is there another way to just turn off validation programmatically, client-side in one call?  I have tried calling Page_ValidationActive=false;  but I get the same result.

 

by: cylikonPosted on 2009-10-08 at 11:29:05ID: 25528513

Note:  I have modified my code

...
OnClientClick="javascript:return DisableValidators();"
...

and

 function DisableValidators()
{        
   for(var i=0;i< Page_Validators.length;i++)
    {            
       ValidatorEnable(Page_Validators[i], false)
    }
  return true;
}

With some more research I found that if I disable all the validation controls in the Page_Load on "IsPostBack" I can get close to what I want.

if (!Page.IsPostback)
{...}
else
{
foreach (BaseValidator v in Page.Validators)
            {
                v.Enabled = false;
            }
}

I'd like to just turn server-side validation of all these controls off and manage which ones get fired on the client-side.  Is this possible?  Can I, through a setting, disable all *server-side* validation of the validation controls without disabling the client-side validation?

 

by: cylikonPosted on 2009-10-20 at 06:44:35ID: 25614001

My solution to this problem was to replace all the type specific validators with custom validators and have each custom validator do its own test for the appropriate condition under which it was relevant.

This was quite a bit more work but I was running out of time and it was a workable solution.
