Hi Everyone,

I am preparing a message sending feature. There after writing the message if I click on the submit button for 3 to 4 times, it is posting for 3 to 4 times. To control this I used the following code:

C#
protected void imgbtnSend_Click(object sender, ImageClickEventArgs e)
{
    imgbtnSend.OnClientClick = "this.disabled = true; " + ClientScript.GetPostBackEventReference(new PostBackOptions(imgbtnSend));
    //code for messaging
}


Now it is working fine in my local system. But it is not working after deploying in server.

I want to make it a single post at a time.

Any suggestion please.

After deploying are you getting any error and what is the behavior of button after click?

No, I have not get any error.

Try Following Code............

C#
protected void Page_Load(object sender, EventArgs e)
    {
        btnsave.Attributes.Add("onclick",      "this.disabled=true;this.value='Processing....';" + ClientScript.GetPostBackEventReference(btnsave, "").ToString());      

}

 protected void btnsave_Click(object sender, EventArgs e)
     {
     }

Thanks Tushar.
you can fixed it aspx page.

MSIL
function ConfirmBooking(imgLoad)
    {
    document.getElementById('imgbtnsubmit').style.display = none;
    document.getElementById(imgLoad).style.display = block;
    return true;
    }

<img id="imgLoad" src="images/Progress.gif" alt="" style="display: none;" runat="server" />
<asp:ImageButton ID="imgbtnsubmit" runat="server" OnClientClick="javascript:return ConfirmBooking('imgLoad');"
    ImageUrl="images/submit.gif" OnClick="imgbtnSend"/>

    protected void imgbtnSend_Click(object sender, ImageClickEventArgs e)
    {
    }

Thank you for your help.
C#
protected void imgbtnSend_Click(object sender, ImageClickEventArgs e)
{

// you better write code to validate whether the message is empty before sending //message and also write code to  clear the message after sending the message.

}

protected void imgbtnSend_Click(object sender, ImageClickEventArgs e)
{
//if (Page.IsValid == true)
{
if (txtMessageContent.Value != "")
{
imgbtnSend.OnClientClick = "this.disabled = true; " + ClientScript.GetPostBackEventReference(new PostBackOptions(imgbtnSend));
//Codes
}
}
}

here the txtMessageContent is the tinyMCE

So I am not going in that way. I want a way so that if the validation message comes then the button will be enabled and also in case of tinyMCE, so I used ClientScript.GetPostBackEventReference(new PostBackOptions(imgbtnSend)).

and at the time if it passes the "if" condition then the button will be disabled.

It is working fine in local system.
But not in Server
Example:

function DisableButton() {
var flag = true;

    for (var i = 0; i < Page_Validators.length; i++) {
        ValidatorValidate(Page_Validators[i]);

        if (!Page_Validators[i].isvalid)
            flag = false;
    }

if(flag == true)
    document.getElementById("<%= btnSubmit.ClientID %>").visibility="hidden";
    return true;
    }


add OnClientClick="return DisableButton()==true?true:false;" to the button property.

Hi Shakil, thanks for your help.
But there is Server side Validation (ASP Validation) also. So if I use

OnClientClick="return DisableButton()==true?true:false;"

Then if I Get the validation error for the first time, then will it work?
shakil0304003 24-Oct-10 10:40am    
If you have validators then you have to write a javascript function, which fire validators & check each validators are validate, if all are fine then it will visibility hidden to the button.
