Sounds like you need log on credentials.

Hello again,
I need help trying to get this to work.
I want to disable a button when clicked, so that the user doesn’t clicking it again.
<script language="javascript" type="text/javascript">
function Form1_onSubmit() {
Form1.btnSaveBudget.disabled=true;
}
...
However, when the button gets disabled then the click event won’t work.
Protected Sub btn_Click(...) Handles btn.Click
I need the click event to fire to do something.
Thank you

Hey I am not a JS expert but here are some suggestions:
Is the on_submit function not meant to return a value? Does returning true make it work. Does it post back at all?
If this doesnt sort it how about instead of disabling it just ignoring it so you would set a bool to true on first press then on further presses check this value and ignore the event.
Hope this helps
Dan

You are capturing Form OnSubmit event, which happens before the page postback. Form submit must return true.
Add a line return true, so that it will postback.

Another suggestion, this type of object identification will not work on all browsers. Start using document.getElementById('<OBJECT_NAME>').

Have a javascript registered through page.registerstartupscript and enable the button through that

Hi All
First of all wish you very happy Ice Cream day (this sunday)...
I am using ASP.Net 2.0 Menu control and which needs to be enable and disable based on user roles. In my web site, I am also using membership API to add users, roles and assigning roles to users.
Now my query : Is there any built in support is available for doing enabling and disabling of menus based on above roles. Or I need to write fancy code for this?
Thanks
Amit

Hey guys,
I'm writing an ASP.NET C# web application that needs to quickly (as possible) display trees that are on the order of thousands of nodes. I know there are commercial solutions out there but have been directed that they are off limits. I have also been told that freeware versions are also a no go. This is partly due to the legalities of using them as well as customer direction.
I've tried building the nodes on the fly but my implementation didn't seem to speed up the rendering of the tree. It just seems like the tree control that is included is very bloated and was not built for VERY large trees.
If you can point me into the right direction I would appreciate it.
Thanks to everyone! This site rocks!

How deep are you going with your nodes? It's common to just retrieve nodes down to the next depth and then when expanding a node, get the nodes two layers down from that. This means that the user sees the nodes that can be expanded. Here's a quick example:
RootNode
|-Level 1
|-Level 2
|-Level 2
|-Level 2
|-Level 1
|-Level 2
Now, imagine that you are expanding the first Level 1 node, you retrieve the nodes below Level 2 so that the user sees the appropriate visual cues:
RootNode
|-Level 1
|-Level 2
|-Level 3
|-Level 3
|-Level 2
|-Level 2
|-Level 3
|-Level 3
|-Level 3
|-Level 1
|-Level 2
As you can see, you only get the information that you need so that you can keep the user happy. I hope that helps.

I have a gridview that displays about 2-50 records. While the stored procedure in SQL Query analyzer or the sqldatasource takes less than a couple seconds to run it takes forever for the gridview to display the data. At a difference instance I have tried to display the data with a repeater. It seems that there is no improvement. Has anybody experienced something like this?
|
|
|
|
|
What are you doing in the stored procedure to make it take several seconds to fetch so little data? I would expect at least less than 0.1 seconds.
Similarly, what are you doing with the gridview to make it take any time to display so little data?
Any code that you can show might help shed some light...

Well the stored procedure summarizes the sales for product(s) sold to customers for every month by salesman. The SQL is quiet complex and I do not think that this relevant though. It just passes back 27 columns"
Shipping company, Curent Year Sales By Month(12 columns), Total, Last Year Sales By Month(12 columns), Total.
But the rest of the code I think that is pretty straight forward:
SqlDataSource1.SelectParameters.Clear();
SqlDataSource1.SelectParameters.Add("Year", year.ToString());
SqlDataSource1.SelectParameters.Add("Prod", prod.ToString().Trim());
SqlDataSource1.SelectParameters.Add("Salesman", salesman.ToString());
SqlDataSource1.DataBind();
GridView1.DataSource = SqlDataSource1;
GridView1.DataBind();
It is the Gridview1.DataBind() that takes forever. The SQL profiler shows that the stored procedure(s) have been executed.

Is the SqlDataSource1.DataBind() necessary? Is the stored proc being executed twice by any chance?

No is not necessary. The stored procedure is not executed twice. I wonder if in IIS there is a limit on the page size.

Are you running your web app and database on the same machine or are you fetching the data over the network? Since your stored proc is only pulling out 27 records, it shouldn't be close to any page size limit.
How quick does the stored proc run by itself when shot through query analyzer?

No they are on different machines. It is 27 columns 2-50 rows. But this is a part of a fairly sizable page. The stored procedure in SQL Query analyzer takes less than 2 seconds in the worst case.
|
|
|
|
|
It has a performance index of .69.
|
|
|
|
|
Since it is only 27 columns with 2-50 rows, that shouldn't be very heavy weight at all.
If you don't mind me asking, what are the other things going on in the page since you say it is a fairly sizable page?

There are just similar queries that provide sales analysis and forecasting. 9 gridviews 2 dropdown list boxes, 7 radio buttons, 1 textbox, 1 button, 8 sqldatasources. The total size of the aspx is about 189k. But at any given time only a few of these are activated.
|
|
|
|

How many of these other features of the page are running along side with the stored proc in question? Are the other gridviews, dropdowns, and 8 datasources active when you run the stored proc? Sounds like a pretty heavy duty page. Just trying to visualize it  Not sure of how much more assistance I can be, but there must be some silly thing going on here. I'd just look through everything and see what is bottlenecking your page. Even with all the features you mention, it should be within reasonable bounds.

It is a heavy duty page but as you say is just a silly thing.
1. At any given time only a single selection is done
2. Just pass parameters to an sql data source.
3. The stored procedure(s) do the work.
4. Analyze/format/populate the data into a grid view.
5. Trigger via the selection item of the main grid 2 more detailed grid views. The process is repeated for the detailed gridviews.
Sometimes there is no page expiration. But then some times when larger datasets are called then for sure there will be a page timeout. It all way though happens on the gridview databind. The larger datasets are not that large (50 recs vs 2). The underlying data of the stored procedure contain lot of data. But how could this be relevant?
On stand alone page there is no issue. But I would hate to separate the gridviews since they provide an nice concise presentation.

It shouldn't.

I wouldn't. Most sales people I've ever run into, like the big picture. Do you have any code profilers to use? You may want to look at execution paths of your code...

I appreciate your support. I just need to hit the sack. It has been a long day.

That is a good debugging tool, the pillow  Maybe tomorrow it'll stand out what is causing the timeouts
Have you tried to increase the timeout for both IIS and the database?
