I've got a drop down list that I want to populate with items from a SQL Server database, which I did successfully, but I can't figure out how to write an if statement that will clear the drop down list based on a selected index and repopulate it with data from another table. The drop down list is inside an update panel that auto posts back.
Basically I want to allow the user to choose an item, but rather than populate another drop down list control, i just want to repopulate the current one with new data.I'm guessing that if I want to get data from more than one table the code below isn't going to work for me. Could I get the data from all the tables at once and store each table data in its own variable until I need to use it? (Each table will have under 10 items, in 5 tables.)
Here is the code to get the data from the database:[Code]....
I have this situation where I have three pages:
The first page, default.htm, is a frameset page that uses the other two pages.
The second page, casemenu.aspx, is a form that contains an object we call "PopupManager": It has an element <xxx:PopupManager runat="server"/>. This object is dependent on the standard ScriptManager, which requires a form.
The third page, header.aspx, contains three links. Each link calls a JScript function that in turn calls a function on the Popup Manager. It makes the call to the popup manager with an expression like 'top.frames.casemenu._PopupManager'.
Now, the problem I have is that I have to change default.htm to be a normal page containing an iframe, which will refer to a new page, container.aspx, which has the original frameset. When I do that, I can no longer access the PopupManager the same way ('top.frames.casemenu._PopupManager' no longer works.)
I would like some way to refer to the PopupManager relative to header.aspx, something like "self.parent.frames.casemenu._PopupManager", but that doesn't work.
My Login Control opens in a FRAME, which is where I'd like it to open, but the control's DestinationPageURL="xxxx.xxx" doesn't use a TRAGET attribute and I'd like the user to be directed to a new page.
Do I have to come up with some fancy code to achieve this?

I don't think I understand fully how ASP.NET does inheritance of controls.I have a user control, ucBase, which has an asp.net label in the ascx file. Code behind references the label and it works fine during run time if the control is not a parent for another user parent.
If I have another user control, ucChild, inheriting from ucBase, the label in ucBase's code is always null. ucChild has no controls in its ascx fileThe server controls (like the label) needs to be declared in the ascx file and not created programmatically.What needs to be done for ucBase to see its own controls when it's a parent user control?
I've got a dropdownlist control that the user can select an an employee name and that should then fill in the detailsview control with specific information about that employee.
My dropdownlist control works fine and I do have AutoPostBack set to true. For some reason my detailsview doesn't work. There's no error message. The detailsview control just doesn't show up.
Here's my code:

How to populate message box from a text box when user enters a value?
View 1 RepliesBasically, I have a textbox where a user can enter an ID from a database. To make things easier, the user can popup a GridView using a ModalPopupExtender to display all the tables columns, and they can Select a row, which then closes the modalpopupextender and sets the textbox to the row's ID column.
So far I have this:
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
string testing = GridView1.SelectedRow.Cells[1].Text.ToString();
((TextBox)dtlsInsert.FindControl("txtNom")).Text = GridView1.SelectedRow.Cells[1].Text.ToString();
}
The 'testing' string gets populated, but it doesn't seem to populate the txtNom textbox. Also, how do I close the modalpopupextender programatically?
I am using 3 text boxes for range selections. I want to show range value in a message box when user enters range in text box.

500 in 2nd text box and 1000 in 3rd text box I want to show "you are selected 501 - 1000"
After entering a value in 3rd text box ,I want to show all ranges in message box.

I am trying to create user by registration form which contains dropdown for profession in ASP.NET MVC
Eg. Individual, professional, manager etc.
some fields are common like name & Last Name...
some fields are unique by profession...
how do i program it with ajax.
I am new to web forms, but how can I populate a web form (form fields i.e. name, job title, tel no etc) with that users information automatically taken from their active directory profile? It wouldd be an Intranet application so all users would be on the domain. How is this done in ASP.net? In Coldfusion I would set the following variable
<cfset user = listLast(cgi.REMOTE_USER,"") > which would grab the user id from AD
Then I would query an employee DB matching up the userid to gather their employee info
<cfquery name="querygetemp" datasource="DATASOURCE">
SELECT * FROM empl.directory
WHERE uPPER(NETWORK_ID) = '#ucASE(user)#'
</CFQUERY>
and then set variables which I would use to populate the form fields further down the page
<cfset varsection = querygetemp.section>
<cfset varjob_title = querygetemp.job_title> etc.
how to get around this in ASP.NET?

I have a web user control that represents a simple message box. It is used to display simple messages like "Item has been deleted", or "The item was saved successfully".
On the other hand, I have another web user control that represents the item in the form of an editable form (I made this a user control because this is used in two different pages). I want to embed an instance of the message box user control inside the editable form. I am writing this right after the @Control directive:
[Code]....
Instead of using @Register directives, I register the user controls in web.config and so far this has worked just fine.
With the above markup, the project compiles, but whenever I try to navigate to a page that contains this construct, I get an HttpParseException exception. Furthermore, Visual Studio states that the tack w7rc9:MessageBox doesn't represent a known control.
What am I doing wrong?

View 2 RepliesAll I would like to be able to do is include one user control within another! Is this possible? I have spent the last hour searching the internet and it seems that I can't find a single thing.
In classic ASP it would be something like:

I tried this but no luck!
