Hello Handy,

I wrote you about the same problem back on april 30,2010.  I am still having this issue.  I tried Tim's suggestion and it did not work.

I will say that I don't know if hte smartwebresources is doing anything.  The ISCore is still looking to a local file.

Are there any other suggestions? 

You can refer to my other post for more info.  As I said back then, if I load everything on a different machine everything works fine.   But this is my dev machine so I need to figure out what configuration option is causing a problem

As I said back then, this is only a problem in IE.

Thanks,

Ethan

I have the same files on my laptop and my workstation and my laptop works no problem.  The step-by-step is opeing any page with a webcombo on it and I get the 2 error messages right away upon loading the page.

Handy,

Attach find the videos you requested.

Video 1:

Shows the performance in our .net 1.1 application that has used webcombo for 4 years.  As you can see, upon load of page, the initializedatasource is hit.  After that, the initialize datasource is not hit again when the user enters a value (one in the list or one that is not).  Upon click of submit button I am able to read the value of the webcombo in the button click event regardless of whether it is in the list or not.  At no point do I attempt to add it to the underlying list of values.  I am just using the value temporarily.

Video 2:

Shows the .net 2.0/3.5 application we are working on now.  In this movie you see that much like in video 1 the initialize datasource only gets hit once--the first time the page is loaded.  Even on the click of the submit button, the initialize datasource does not get hit again.  However, when I get to the click event of the button, the webcombo.text value is blank. 

If I put a stop in the onload event, the webcombo.text value will be correct.  By the time I get to the button click event it has been cleared.  None of my code runs in between these 2 events.

I also created a new test page (within the same project) with just a webcombo and a button.  The same performance occurred here. 

video 3:

Shows a .net 2.0/3.5 new project created just to test this issue.  There is one form with a single combo box and button.  Here I see different performance than in video 1 and video 2.  In video 3 the initialize datasource is hit multiple times--on initial load of page, when user starts to type, when user tabs from webcombo, and after I click submit button. 

In this project I agree with you that when it hits the initialize datasource after the click of the submit button it will clear the value from the combo if it is not in list.

So I added a variable to hold the wc.value until after the combo populates.  It then sets the value if the temp variable is not blank.  As you can see from the movie, the value appears to be set while I am in the initialize datasource event.  However, as I step into the button click event, the value is gone.

The only way that I can get this to work is if I check for a value in the field and then build a union query with the value that does not exist in list.  I would rather not have to rewrite all my code to take this into account.

So, my questions are the following:

-- Why am i getting such different performance between video 2 and video 3?

-- What is your suggested solution?

-- If video 3 is how it is supposed to work, is there anyway to prevent the numerous hits to the intialize datasource.  I don't understand why the webcombo has to requery so many times for a user entering one value into one webcombo.  In .net 1.1 version I hit the sql server once for each combo.  Now it is approx. 5 or so connections to the sql server for a user entering a single value.

Thanks for your time,
Ethan

I am not trying to add the text value into the list, I just want the text accessibly by the button_click.  I recreated a sample page as suggested and it worked like you said it would.  However within my project it does not work this way, the dlls are the same and the aspx code is the same.  Within my project I put breaks in for most of the functions, the text was present in the page_load of the postback but the initializedatasource was never hit, then the text was gone in the on_click.  I did as you suggested and used the addItem event, but the text was also gone by the time it hit the breakpoint in this event.  What would cause my project to handle the webcombo functions different than a project I create from scratch?  Is there some other file that contains settings that may need to be changed?  Or is there code hidden somewhere in the webcombo?  This project is one that I just upgraded from Webcombo2.

Thanks,
