Timing Mouse Pointer changes

[Dave]

I have a page that, when invoked, it runs a while (~ 15 seconds), then
displays a DataGrid control. What I want to accomplish is to have the mouse
pointer go to 'wait', then after the control displays, return to 'default'.

What happens is the SetWaitPointer( ) routine changes the cursor to 'wait',
but before the data grid is displayed on the page, 'SetDefaultPoin ter()'
runs and changes the cursor back to 'default'. This happens about 3 seconds
in, so the user spends 12 seconds looking at a blank window and a default
mouse pointer. I'm imagining that's when he will get that uneasy "Don't
leave me hanging, Dawg" feeling.

I have included a simplified version of the code I use for this. Can anyone
point me to a solution to this? How can I make sure that
SetDefaultPoint er() won't fire until the control displays?

Thanks,

Dave

'The platform is Visual Studio 2003, in-line VB.NET
'The functions SetWaitPointer( ) & SetDefaultPoint er() are basically
javascript:
dim sCommand as string = "document.body. style.cursor = 'wait'; "
response.write( "<script language=JavaSc ript>" & sCommand & "<" &
"/script>")

Sub Page_Load(Sende r As Object, E As EventArgs)

SetWaitPointer( )

DisplayDatabase Grid()

SetDefaultPoint er()

End Sub

Dave,

I have not direct the solution because I did a while no JavaScript,

However what you are doing is when I see it right.

Set on the serverside the Wait Cursor (this has no effect on your
clientside)
Initialize
Set on the serverside the default Cursor

Sent the page.

I cannot believe that that is what you want.

Probably you want to set the cursor before the postback from the client to
the server and set it to default when the page is again received on the
client.

As I said I have no snippet for it at hand, maybe somebody else.

Hello, Cor.

The key phrase of yours is "when the page is again received on the client".

I am somewhat of a newbie in web developement. I do not know how to
determine this event. Just playing around, I took the SetDefaultCurso r()
out of my code, enclosed it in "<%....%>", and stuck it near the bottom of
all the html code. That worked fine, except that it unexpectedly made the
routine run for 62 seconds instead of 15 seconds.

Anyway, if you know what I should look at to determine when the page is
received by the client, I would appreciate it.

Thanks again,

Dave

Dave,

Quickly I found this, maybe I look tomorrow, however no promish

Button1.Attribu tes("onclick") = "document.body. style.cursor='w ait'"

However it shows only the wait status there where there are no controls, I
think that I know now how to do it, however I have no time to write that
now.

Thank you, Cor. I have used this method (Button1.Attrib utes.....) in the
past, but I don't know how to make it work for my present problem.

If I am reading between the lines correctly, you may have a solution
forthcoming. If so, I am patient - I can wait.

I think there is probably some trappable event, but I don't know what it
would be. I know the page knows - because the cursor changes to 'Working in
Background' when you touch the browser's border with the cursor.

Thanks again,

Dave

Dave,

In my opinion does this one what you ask.
\\\
Private Sub Page_Load(ByVal sender As System.Object, _
ByVal e As System.EventArg s) Handles MyBase.Load
Button1.Attribu tes("onclick") = _
"for (var i=0;i < document.all.le ngth; i++)
document.all(i) .style.cursor = 'wait';"
Dim str As String
End Sub
///
I hope this helps a little bit?

Cor

[Dave]

Well, thank you Cor, but that doesn't do it. I want this to happen without
button clicks.

Someday, I'll either get better at this and figure it out, or I'll browse
onto a page that does it, and maybe by viewing the code or asking the
author, I'll get it.

I appreciate you taking time out for this little problem of mine.

Dave,

What is than the action that does the return?

Cor

[Dave]

Cor,

This is what I think happens:

First My code. All is in Page_Load(), and all should happen automatically -
the page's only purpose is to hold and display the data grid.

1) Set Cursor Wait
2) Run a 15 second procedure
3) Set Cursor Default

What happens is while the user is waiting for step 2 to complete, step 3
kicks in after only 3 seconds, and the cursor goes back to default for 12
seconds, then the data grid displays.

I think the reason for this is that the actual 15 second procedure takes 3
seconds for the database operation, and it takes the browser 12 seconds to
process the information it gets from the server. But since the server is
done, it sends the reset cursor statement prematurely. If there was some
way I could capture when the browser actually rendered the data grid, I
think I would have it. But I don't know enough client-server programming to
do that. Someday I will ....

Thanks,
Dave

Dave,

Did you include the code I have in the previous message.
In that is not a setting to default.

In my test it did work.
