Solution 1

You are almost there...

You only need to change the incrementation to happen before comparison by moving the ++ before the value.

Another smaller thing, rather than using Response.Write to output JavaScript, user ScriptManager.RegisterClientScriptBlock ;)

Example:

C#

protected void Button1_Click(object sender, EventArgs e)
{
    // Increment before compare
    if (++count > 5)
    {
        Button1.Enabled = false;
        TextBoxFN.Enabled = false;
        TextBoxLN.Enabled = false;
        TextBoxBD.Enabled = false;
        TextBoxCP.Enabled = false;
        TextBoxADRESS.Enabled = false;
        TextBoxEMAIL.Enabled = false;
        txtcaptcha.Enabled = false;
        DropDownListCS.Enabled = false;
        DropDownListGENDER.Enabled = false;
                
        // Register JavaScript items rather than using Response.Write
        ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "alertFull", "alert('Sorry Registration is full');", true);
    }
}

thanks for your response but the problem is still not limiting the submit button

Gideon van Dyk 29-Jan-15 22:35pm

As far as can be determined from your post, you want the button to be disabled after 5 clicks, this code does exactly that.

Unless you would want to define the limit as say an attribute on the button?

Member 11407981 29-Jan-15 22:46pm

sorry i for got to say when the submit button is clicked the page is redirect to another page

Gideon van Dyk 29-Jan-15 22:54pm

So you are using a cross page posting I see... I will submit a possible other solution incorporating both server-side and JavaScript.

Good You can include this also to the answer;
count++ : will use the value before increment
where as ++count : will increment the value before use

Member 11407981 29-Jan-15 22:48pm

yes i want to define the attribute on the button

Member 11407981 30-Jan-15 0:06am

if (++count > 5)
{
Button1.Enabled = false;
TextBoxFN.Enabled = false;
TextBoxLN.Enabled = false;
TextBoxBD.Enabled = false;
TextBoxCP.Enabled = false;
TextBoxADRESS.Enabled = false;
TextBoxEMAIL.Enabled = false;
txtcaptcha.Enabled = false;
DropDownListCS.Enabled = false;
DropDownListGENDER.Enabled = false;

Response.Write("<script LANGUAGE='JavaScript' >alert('Sorry Registration is full')</script>");

}

}
