Hello group,

I'm creating a page (using VB.NET) where I need to have a cancel button on page, also, I'm using few RequiredFieldValidator on the page (to validate a form), in the BtnCancel_Click() event I'm redirecting by:

Response.Redirect("index.aspx")


However, as soon as I click cancel button those RequiredFieldValidators print messages on the page and the doesn't redirect user.

Any help is appreciated.

Regards,
ak

Response.Redirect("index.aspx")

I think you can set "CausesValidation" to false on your cancel button to stop the required field validators

hi akohan,

                Make " CausesValidationproperty" property  of cancel button to false



CausesValidation="FALSE"

and under CancelButton_Click you have to write

Response.Redirect("index.aspx");

then it will redirect to the user.

Thanks to all but  RequiredFieldValidators  has no such a property! I went thru its properties but didn't find it

Any idea?

You're setting the CausesValidation during design time, correct?  It would be too late if you code it during the click event.

Right. I made those validation during make the UI. Now what is the solution?
Does this mean ASP.NET has limitations in this case?

Can you post the code you have in BtnCancel.click?

Does you button code declaration look like this:
<asp:Button ID="Button1" runat="server" Text="Button" CausesValidation="False" />

hi akohan,

                after "CausesValidationproperty" property  of cancel button to false and

under CancelButton_Click event  writing Response.Redirect("index.aspx");

Can you post some code?
Can you put a break on your response.redirect("index.aspx") line and step through the code?
Does it ever hit that line?

I don't see where you have set the CausesValidation property of BtnCancel to False

should be like this:
<asp:Button  ID="BtnCancel" runat="server" Text="Cancel"  CausesValidation="False" />

UnifiedIS,

I had used in VB code not in HTML section as:

BtnCancel.CausesValidation = FALSE

but I guess it was wrong. I will use your code and will get back to you soon.

Thanks,

hi akohan,

           modify your code in your source page/html page.

<asp:Button  ID="BtnCancel" runat="server" CausesValidation="False" Text="Cancel"  />



-------------------------------------
and  modify this code in your code behind page.

Protected Sub BtnCancel_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles BtnCancel.Click
 
        Response.Redirect("index.aspx")
 
 
    End Sub


please check my just previous post .

There's not any reason to do it at run time, you're not ever going to change it.  Just set the property during design time in the BtnCancel properties window.  Let the IDE write the code!
