Run client side javascript with Validation Control

[goscottie]

I need to find a way to either

1. run and check all Validation controls (in my case one
CompareValidato r) and run client side javascript function. In this
case I'll use <asp:Button>. So if all validation passes, run custom
javascript. Or.
2. from my client side javascript to run Validation check and then
perform remaining client side function. So in this case I'll use
<input type="button">.

So far, challenge in case 1 is how to capture validation failure and
limit and stop further client side code execution. I had this code.

Button_Search.A ttributes.Add(" onclick",
Page.ClientScri pt.GetPostBackE ventReference(B utton_Search, "") +
";Search(); ");

where Search() is my client side function, which gets executed with
failed client side validation.

In case 2, I would like to do something like... (I'm doing this with
RegisterClientS criptBlock)

function Search()
{
window.top._som evalue = 'xyz';
if (whateverclient validationfucti oniscalled()) // client side
validation function name generated by ASP.NET
window.top.hide PopWin();
}

<input type="button" onclick="Search ();">

Any help appreciated.

I think you are trying to do what I do. Here is what I do:

In the code-behind:

// Add Submit Confirmation
btnSubmit.Attri butes.Add("onCl ick", "return ConfirmSubmit() ;");

Then in your aspx page within script tags:

function errorArgs()
{
this.IsValid = true;
this.errorMsg = "";
}

function ConfirmSubmit()
{
var IsValid = true;
var display = "";
var err = new errorArgs();

VerifyVacationD ays(err); // Create your validation code in here.

// I have multiple validation routines that I call, but I put it
down to 1 for ease of reading

if (err.IsValid)
{
return confirm('Are you sure you want to Submit?');
}
else
{
alert(err.error Msg);
return false;
}
}

The key is the "return" in the buttons OnClick event. If it sees
false it will not post back. If it sees true it will.

Thanks for quick response.

So looks like you are calling your own validation functions. I would
like to utilize already generated server-side validation. I just
found my own answer just after posting.

With case 2, where...

if (Page_ClientVal idate('SearchVa lidation')) // that was the function
name I was looking for. SearchValidatio n is the ValidationGroup name.
window.top.hide PopWin();

and used in server side....

<asp:Button ID="Button_Sear ch" runat="server" Text="Search"
ValidationGroup ="SearchValidat ion" OnClientClick=" Search();" />

I'm not sure <asp:Buttonis completely necessary or not here but I'll
move on. Thanks again.
