Hi guys, I am wondering how would one achieve the following: I tried to show the modal when user clicks button and then to hide it when code finnishes. But it doesn't show it, I think it's because the stqatenment has to finnish.

Does anyone know how to do this?

C#

protected void btnImport_Click(object sender, EventArgs e)
{
    madalpopup.show();
    //do some importing 
    modalpopup.hide()
}

All my code works. I just want to know how to achieve this. That is why I dont submit my code.

No, it won't work.
Why not? Because the box is Modal - and a modal popup has to be closed before control returns to the statement that displayed it.
If you want to show a box while a process is going on, use a BackgroundWorker thread instead.

Exactlky what are you trying to do? I assume you are showing a "wait...I'm busy" box or similar while you do a long task?

mrDivan 21-Dec-12 3:49am

yes that is correct

And your environment? Winforms?

Hi no its an asp.net application

Right - that gets complicated, because there are two different computers involved: the server (where you are running the task) and teh Client (where you are displaying the status) - the server can't influence client modal information!
There are a couple of things you can do - have a look at these:

A good start would be fixing your keyboard. Its shift key doesn't work. I fixed the effects on your text, but realized the pointlessness of my doing since your code most likely looks the same. And the Show[^] and Hide[^] methods require to start with a capital letter, just as many other .NET methods do.

With Christmas forthcoming, that could be your aunt Martha's long awaited chance for a last-minute present to you that you really appreciate.

Or you could use the Windows on-screen keyboard, but that's only feasable as an intermediate solution.
