Hi,
I'm developing a user control that is loaded dynamically into a page.
The user control has 4 dropdownlists(DDLs). Each is populated dynamically depending upon the values selected in the previous DDLs. Each DDL is in a separate updatepanel (not nested) and has the autopostback set true. Each has its trigger set as the SelectedIndexChanged event of the DDL before it.
The problem is, if the user selects a (non default) selection 'x' in the first DDL and tries to select something say 'p' in DDL2, on postback, SelectionChangedEvent for DDL1 is fired (as per normal page lifecycle) to select 'x' which reloads DDL2 before SelectionChangedEvent of DDL2 is fired. This causes the selected 'p' in DDL2 to be lost and the page comes back again with the default selection for DDL2. Similar is the case with other DDLs. Here's the logic of my code:
Page_Load()
{
//Load DDL1
}
UpdatePanel2_Load()
{
//Load DDL2
}
UpdatePanel3_Load()
{
//Load DDL3
}
UpdatePanel4_Load()
{
//Load DDL4
}
OnSelectedIndexChanged_DDL1()
{
//Load DDl2,DDL3,DDL4
}
OnSelectedIndexChanged_DDL2()
{
//Load DDL3,DDL4
}
OnSelectedIndexChanged_DDL3()
{
//Load DDL4
}
What this does is, when OnSelectedIndexChanged_DDL1() is fired on postback to select 'x' in DDL1, it reloads DDL2,DDL3,DDL4 and by the time OnSelectedIndexChanged_DDL2() is fired (because of the selection 'p' made by user) the statement 'DDL2.SelectedValue' inside it only returns the default DDL2 selection 'd' and not the user selection 'p'. Can I get the value selected by the user in Page_Load itself (say from Viewstate) instead of waiting for OnSelectedIndexChanged_DDL2() to fire?
I know it's really long and might seem confusing but I really need a solution to this and am losing my mind!  Any help would be great. Thanks

What is the problem with this?
Just use Request.UserHostAddress() / Request.ServerVariables ["REMOTE_ADDR"]
DateTime.Now to get date etc.
Now save it to database.

Hi, I created one web applicaiton which contains aspx and aspx.cs files. I want this application as exe file to give this to client. So i tried this by adding webseup project to solution and i created a msi/exe file for this project. Up to here every thing is fine.
But when i install this appliation it is creating a folder with all aspx and aspx.cs files. But i dont want to place .cs files at client place.
I tried by publishing website. Then its is giving dll's. But i can;t make it as exe at that time, bcz its giving error as "already precompiled".
what is the solution for my problem? how can i give exe file to client which doesn't contins code files once he installed in his machine.G. Satish

You have to use a Precompilation.
Right click on your Web Project and go to Properties and go to "MsBuild Option" and in that tab there an Option that says
"All this precompiled site to be Updatable" and try againVuyiswa Maseko,

You can't hide individual rows but you can filter the dataset so only the required rows are rendered

You can go to properties of each row and give validation there.
Rightclick row->properties->visibility->Expression. There give the validation for each row seperately. (I mean this u need to do seperately for each row)
=IIF((Parameters!hisid=0,false,true)
=IIF(Parameters!hisid=1,false,true)

The rows in a ssrs table are rendered dynamically based on the dataset assigned, you can't control the individual table rows in this way.

You may have done for values in the row not for the complete one..!
Tht guy is asking for complete Row..!
Just think it you will find the solution.

| Does 2 rows in table mean "In SSRS 2 rows in a single table" If so as per my knowledge i have worked on this kind of scenario of hiding rows based on parameter value as i have mentioned in my first post. Naina

I doubt that very much. Prove it. Show an application of it or write an article.

Software as a Service (SAAS) is a cloud computing concept.........and not the web services concept.
I want to develop an application in which business process change leading to user interface changes and user interface can lead to database change if required.
lets say user profile page is there initially, which store some information but not DOB, but due to some reasons i want that additional field. this can be done easily through database changes, then entities changes and then complie and re-deploy the application...............but the owner of the software should be able to that at run time itself and add that field.
go to www.salesforce.com and hav a look at it...........
Thanks

Hi all,
I am sorry if this is an inconvenient question to you.
I am a programmer from Bangladesh. I am very much impressed with Extjs framework. I want to use it with c#.
Now my question is If I develop website using ExtJS and publish it under certain domain name (e.g. www.my-domain.com) then will the authority of ExtJS force my clients for license?
thanks for your time.
