Is it possible to disable an ImageButton when processing?

I found a way to disable a Button when processing doing this:

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        If Not Page.IsPostBack Then

           Dim strProcessScript As String = "this.value='Processing...';this.disabled=true;"
           btnProcess.Attributes.Add("onclick", (strProcessScript + ClientScript.GetPostBackEventReference(btnProcess, "").ToString))

        End If
    End Sub

Open in new window

But I can't do the same for an ImageButton

Try same thing for image button, only change the following...


imagebtnidhere.Attributes.Add("onclick", (ClientScript.GetPostBackEventReference(btnProcess, "").ToString) + ";return false;")


This will result in even you click on image button, nothing will happen.

But remember to remove that "return false;" when processing is done.

hi.. you can disable button like this
Write this code in button clicked event. It is for disable button for some time.

Javascript :
<script type="text/javascript">
Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(BeginRequestHandler);
function BeginRequestHandler(sender, args) {
document.getElementById('<%= lblMessage.ClientID %>').innerText = "Please Wait...";
document.getElementById('<%= btnSubmit.ClientID %>').innerText = "Please Wait";
args.get_postBackElement().disabled = true;
}
</script>

Code behind :

protected void btnSubmit_Click(object sender, EventArgs e)
{
System.Threading.Thread.Sleep(4000);
lblMessage.Text = "PostBack completed!!";
}

.aspx page
//And also you have to put script manager between form tag.

<asp:UpdatePanel ID="updpnlSubmit" runat="server">
<ContentTemplate>
<asp:Button ID="btnSubmit" Text="Submit" runat="server" OnClick="btnSubmit_Click" />
<asp:Label ID="lblMessage" runat="server"></asp:Label>
</ContentTemplate>
</asp:UpdatePanel>

Hi, mroonal. I tried your piece of code but it doesn't work. Imagebutton still keeps being enabled when processing.

Hi samirbhogayta, I can disable a Button control, but I can't do the same for an ImageButton.

It's quite strange that you can disable a Button control when processing, but it's not possible do it for ImageButton.

Ok, don't worry try this

document.getElementByID(imgbtn).disabled = true;

document.getElementById(imgbtn).disabled = true;

If still not working, then you can use simple UI blocker plug in.

like jQuery BlockUI

I found myself the solution:

" this.disabled=true; "  should come first.

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        If Not Page.IsPostBack Then

           Dim strProcessScript As String = "this.disabled=true; this.value='Processing...';"
           btnProcess.Attributes.Add("onclick", (strProcessScript + ClientScript.GetPostBackEventReference(btnProcess, "").ToString))

        End If
    End Sub

Open in new window
