how to Disable Imagebutton in Asp.net

[sujith(ARS)]

Hi,
I'm a beginner in ASP.NET/C# development.

Does anyone know how to disable an ImageButton on ASP.NET page after the button is clicked once? Basically I dont want users to click the submit button more than once and the submit button is an Imagebutton.

I searched thru the net and found different solutions for disabling the imagebutton,But my problem is i have more than one imagebutton on my page and i want to disable all of them?

Expecting reply
Thanks in advance,
Cheers,
Sujith

In your codebehind for the click event put :

Private Sub btnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
btnImagebutton.Enabled = False
End Sub

hi,
i tried the property "Enabled = false" of the image button .But still its not working.
//-----^^code---
private void ImgBut1_Click(object sender, System.Web.UI.ImageClickEventArgs e)
{
ImgBut2.Enabled = false;
}

//-----^^code---
Can you please tell me where i went wrong

Did it disable that one button after you pressed? Or it was still enabled?

i don't know about asp.net, but with regular html have javascript, it might look something like this:

<input type="button" value="Submit" onclick="this.disable=true; this.form.submit(); />

hi brenda,
I'm sorry ,it worked fine.But the matter is since it's the server script the button will be disabled only when we get back the response from the server.

But my requirement is to block the submissions from any other imgbuttons while one request is being processed.

hi sde,
your code with a little modification ,i was able to block mutiple request from same button.
Code:
private void Page_Load(object sender, System.EventArgs e)
{

this.Image1.Attributes.Add("onclick", "this.value='Please wait...';this.disabled = true;" + this.GetPostBackEventReference(this.Image1));
}

But i wasn't able to disable all buttons.

Expecting more help from all
Thanks in advance
Cheers

make a new function that disables all the buttons, .. then call that function on click.

some suedo code:

private void DisableInterface()
{
  btnSend.value = "Please Wait...";
  btnSend.disabled = true;
  txtMyField.disabled = true;
  txtMyOtherField.disabled = true;
}

 private void Page_Load(object sender, System.EventArgs e)
{
  this.Image1.Attributes.Add("onclick", "DisableInterface();" + this.GetPostBackEventReference(this.Image1));
}

like i said, it's suedo code, .. but you get the idea.

hi sde,
i'm sorry for the delay in replying.its b'cos i was out of my office for some time.
sde ur code wasn't working i don't know why?the browser can't understand the other image buttons.it works fine with any other controls except imagebutton.

i was able to fix it by using GetElement by ID functionality.
Code:
__________________________________
private void Page_Load(object sender, System.EventArgs e)
{

this.Image1.Attributes.Add("onclick", "this.value='Please wait...';this.disabled = true;"
+"document.getElementById('ImgBut2').disabled = true;"+ this.GetPostBackEventReference(this.Image1));
}
