If you have validation group say 'Send' on the button, write

sbValid.Append("if (Page_ClientValidate('Send') == false) { return false; }} ");

you have to specify validation group name for function Page_ClientValidate.

Hi there, I came up with this same solution a time ago, it works with .net 1.0 and 1.1, don´t you have something like it with asp.net 2.0?

Just what I was looking for after stuffing around with client-side options, worked like a charm first time. Cheers!

This is great!! Question: how do you disable all buttons within a page onclick instead of just the current button?

Worked Great on a standard aspx form. Thank you very much. However, it did not work in a custom control (ascx). It worked, except it did not cause a post back. Any ideas?

What about client side validation? I want to preform Client-side validation and, if successfull, disable the button and postback. If client-side validation fails, then leave the button enabled.

Any ideas or did I miss something in the code above?

Thanks,

It will work in Vb.Net. Simple make the following changes:

sbValid.Append(Me.Page.GetPostBackEventReference(me.cmdMakeNonSupervisor ))

This code doesn`t work using VB in ASP.Net. The reference to this produces an error: this is not declared.

Excellent...works well

I get a "Object not set to an instance of an object" at line "sbValid.Append("if (typeof(Page_ClientValidate) == 'function') { ");".

Any idea why?

Place it in a Page_Load

Like
void Page_Load(Object Sender, EventArgs e)
{
System.Text.StringBuilder sbValid = new System.Text.StringBuilder();

sbValid.Append("if (typeof(Page_ClientValidate) == 'function') { ");

sbValid.Append("if (Page_ClientValidate() == false) { return false; }} ");

sbValid.Append("this.value = 'Please wait...';");

sbValid.Append("this.disabled = true;");

sbValid.Append("document.all.btnSubmit.disabled = true;");

//GetPostBackEventReference obtains a reference to a client-side script function that causes the server to post back to the page.

sbValid.Append(this.Page.GetPostBackEventReference(this.btnSubmit));

sbValid.Append(";");

this.btnSubmit.Attributes.Add("onclick", sbValid.ToString());

}
<form runat="server">
<asp:Button id="btnSubmit" text="whatever" runat="server" />
</form>

This code worked first time, you need to replace the btnSubmit with the ID of your button, then everything is fine

Excellent Piece of code, exactly what I was looking for, thanks for posting it.

This worked except the line for the line of "sbValid.Append("document.all.btnSubmit.disabled = true;"); "

This was causing an error on the page so I committed it out. I also added a disable button to the post back to keep the button disable (that is what I needed) and this solution worked great. Thanks for the help.
