I'm designing a web page that allows a user to enter previous employer information. I'll need the ability to add multiple user input sections to capture information for each previous employer. Is there a user input control I should use to do this? Is it possible to add additional controls or user input sections when a user clicks on a button?

I have a quick Linq to SQL question. I am trying to write a Linq query that has multiple where clauses depening on user input. What I would intuitively code is:
Dim arrTerms As Array = txtUserInput.Text.Split(" ")
Dim q = From newsitem In db.MyNewsTable _
Where newsitem.Contains(arrTerms) _
Select newsitem
Listview1.DataSource = q
Listview1.Databind()
Unfortunately, though, the "Contains" operattor does not accept an arraylist, or array, or anything but String.
for example, the following url is generated

based on the title: How to Install a Copy of Windows XP on a MacBook With Boot Camp.
Is there any .NET code generating the user friendly url out of user input?
I've embedded multiple user controls into the same page. The user controls typically have 2 different views, an edit/default view and a completed view. When the user completes an edit then I switch the MultiView to the completed state. This pattern works okay in pages.
The problem is when I go back to the master view/page then the user brings back the control, the view is still in the completed state.
What are some simple methods for resetting/correcting the multiview state? I could have a Reset() function on every control but it feels like I may be able to avoid that.
Update:
This page is designed to show an account/profile view and it has the following parts:
<asp:MultiView>
...read only view
<asp:EmailEditView>
<asp:AccountEditView>
etc..
And then each of those views has a user control. Inside the user control, we have something like this
<asp:multiview>
<asp:view id="edit"/>
<asp:view id="completed"/>
I've found the following problems with this design:
When the user completes an action of user control such as changing an email. The view stays in the finished state even when they go back to it a second time. When the user goes back to the original form the data is stale. This design really screws with the postback mechanism. If I don't use !IsPostBack on the main form for databding then my dropdownlist on the sub forms will not work. However, once I add the !isPostBack on the main form then the data becomes stale.
I can add a "reset" flag to every user control and add something like this
if ((!IsPostback) || (reset) )
As well as resetting the view. In the other scenario, I can add an event handler to load the reload/bind the data when the user clicks "back", i.e where I change the form back.
I'm looking for a way to have user upload as many images as they want (perhaps via drag and drop) or dynamically adding more upload box.I thought statically fixing (say 6) HTML upload input box is slightly limiting and the user have to click "Browse" button (6 times in this example) and navigating to the folder to pick the file.What is the best practice to achieve this so users find it easy to use? Perhaps with some AJAX magic?I also wouldn't mind having the user click "Upload more" to reveal (say 6 more) HTML upload input box.
View 2 RepliesCreate a class Employee which will implement the below interface: IEmployee. The application should accept the function to invoke and its parameters from the console in the Format:
[MethodName]:[Parameter1]:[Parameter2]
Ex: SetProperty:Age:44
The implemetation shold have the necessary checks on whether the input is in correct format by handling like FormatException.And the program should be able to continuously accept the input and print corresponding output until the input given as "Exit".

Issue: I am unable take the user input in the corresponding format.in the above code everytime I have to give the user input in the format "Set:Age:33" but this is not I m looking for .Actually firstly the expected input and output should be given in the format as per the screenshot I have attached.
I have a user control (ascx file) that contains an interface for users to change the data retrieved from the db. So, I am displaying data and most of this data can be edited by the user. When the user enters text into a textbox, and clicks "Save Changes", the value they typed in is lost and not persisted to the database. I realize now this is because the SaveChanges button does a postback, and the user control gets reloaded with its original valuesbefore the code within my SaveChanges button gets executed. I'm not sure if there are properties I need to set to save the input data, or if I need to write my own code to do it. What is the generally accepted method to do this? (Also, all of the controls in the ascx file are wrapped in an Update Panel.)

I would like to program an Input Box that comes up when a user clicks 'Find' button. It asks 'Please enter an employee number'. Then it takes the employee number typed into a text box and searches a dataset for that specific employee record.
I know that it should be server side because the client may not have the proper javascript installed or diabled. Therefore, can someone give me some code to put in code behind that can pop up an input box and use the input after, if this can be done?
I have a 2 page signup form, on each page the form fields are seperated into sections. Each section is a user control, and there are 2 controls on each page. My question is, how do I get the data from page A to B. I'll be using a webservice to insert the data into SQL so I'm not worried about that portion of the process.

On my aspx page I am trying to capture user input and then tried to save them in database and also trying to post them onto another page. Now I am using the following code on the button click event:ASPX CODE:
<asp:Button runat="server" ID="cmdPress" Text="Save"
ValidationGroup="ValidateId" Height="26px" onclick="cmdSave_Click"/>
CODE BEHIND:
SaveCustomer();
SaveRequest();
cmdPress.Attributes.Add("onClick", "update(" + ID.Text + ");");
Now when I click save button then it the page waits and then I have to click again to close the page automaticallly and move to the next page. Can anyone tell me why I will have to click Save button twice to activate the button.
I need to check information the user has entered on a page against what I have in my database to see if he is entering duplicate data. It is up to him if he wants to proceed or not. I just need to alert him.
The problem is I don't own the button that he clicks so I can't hook up a javascript confirm to the button click. I am running within vendor code. I have an "override PageLoad()" procedure where I can test what page they're currently on. If they are on page "EditForm.aspx" and would normally navigate to "UserFinish.aspx" without any custom code of mine "interfering", I want to test what they've entered on EditForm.aspx and present them with a popup if they've entered duplicate info, and if they click OK button then proceed to UserFinish but if they click Cancel then stay on EditForm.
I have 3 tables as follows:
1 - Members containing the following fields:
MemberID int
MemberName
2 - Companies containing the following:
CompanyID int
CompanyName
CompanyType (S=Supplier, R=Retailer, C=Competitor)
3 - Member_Company_Link containing the following:
MemberID int
CompanyID int
The Company table contains any Company with a potential relationship to a "Member". For example:
Companyabc = C (Competitor)
Companyxyz = S (Supplier)
When a new Member record is entered, the user selects from two dropdowns: CompanyType (Supplier, Retailer,Competitor); and CompanyName. The CompanyName dropdown is populated depending on the value selected for CompanyType so if the user selects "Supplier" for CompanyType then only those Companies with a CompanyType of "S" for Supplier will be listed in the CompanyName dropdown.
The use can enter up to 10 CompanyType/CompanyName combinations. When the record is saved, these CompanyType/CompanyName combinations are saved in the Member_Company_Link table. One record for each CompanyType/CompanyName combination is entered in the table.
The problem I'm having is in the retrieval process. I have a "search" screen in which users can select certain criteria to list Members by and one of them is CompanyName. For example they want to see all Member records with "company xyz" as a Supplier and/or "companyabc" as a Competitor. Because each Member can have multiple Supplier and/or Comptitor records I can't figure out how to loop through them to match on the value entered by the user. If Member1 has 5 corresponding records in theMember_Company_Link file and 4 of them contain Companies that are Competitors (Competitor1, Competitor2, Competitor3 and Competitor4) and the search criteria is to find records containing "Competitor3" how can I loop through the values in the Member_Company_Link file for each MemberID to see if there is a match for "Competitor3"?
I know this post is too long and most of you will have ignored it by now but I'm hoping someone will have a clue because I've already spent more than a day trying to figure it out. It seems I have to store multiple values in an array but I have no clue how to do this.
I want to put an input table on a web page using ASP.NET. The input table has 3 columns: date, quantity, and price. The number of rows is variable, depending on user input. The code behind will read the data and perform the necessary calculations. The data will not go into a database. It would be nice to have some client-side or server-side validation for the data, such as required fields and range checking.
Which control(s) in Visual Studio 2008 will perform what I want to do?
I have a gridview that was displaying and handling postbacks correctly, that is, until I upgraded to .net 4.0 (vs 2010) from .net 3.5. Now I am getting the classic (and in this context meaningless) "Input string was not in a correct format" error upon postback. The postback is initiated by a command button and the row command event handles everything nicely.
The trace shows internal grid postback handling and nothing else:
[FormatException: Input string was not in a correct format.]
System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal) +9594283
System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info) +119
System.Convert.ToInt32(String value, IFormatProvider provider) +48
System.Web.UI.WebControls.GridView.HandleEvent(EventArgs e, Boolean causesValidation, String validationGroup) +1047....
From experience, I know this happens on late binding with wrong type casting on the ASPX side of things. However, nothing has changed. The code is the same, the only thing that changed is the upgrade to 4.0.
I have tried everything I (and a coleague) can think of to figure out what the issue is without luck. No error is raised on the code behind in any method. The only error raised is the Page_Error event and the error object contains the same crap you see in the yellow screen dump (above).
UPDATE: I narrowed the issue down to the RaisePostBackEvent method. I had to reflect the System.Web (for educational purposes of course :) assembly to figure out the code executing after my RowCommand logic(which is fine) breaks. This happens in the HandleEvent method. It checks for known command names (e.g. Select) and if it can't find a match, it defaults to the following:
[Code]....
Is this a bug or am I doing something wrong? The row object is NULL which is why it defaults to the cast. The cast assumes the argument to be an integer however and in my case I am passing a string as an argument?
I have an accordion control which is databound, within each pane I add a datagrid with an image button column, clicking on one of the buttons should cause a popup (modal panel popup extender) which it does.
However it also causes a javascript error
Microsoft JScript runtime error: Sys.InvalidOperationException: Two components with the same id can't be added to the application.
This error was originally on the popup extender control so a quick google I found this [URL] .... and applied the fix, however I still get the error but not its on 'ModalPanel$DropShadowBehavior'
Im not sure where to go from here?
I have this code , to redirect user when an error is detect on a page, and to notify the admin
vb Code:
Protected Sub Page_Error(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Error
REPORT IF ERROR DETECTED Dim a As New errorhandler
a.reporterror(Page.Title.ToString & " "
& Request.Url.Host.ToString, Server.GetLastError.ToString)
End Sub
then under another button I have this try and catch , i wud like to show the user there is an error on the date input format.
vb Code:
Try
aaa = dateTextBox.Text.Split("/")
bbb = aaa(2).Split(" ")
If (bbb.Length > 1) Then
a = aaa(0) + "/" + aaa(1) + "/20" + bbb(0) + " " + bbb(1).Substring(0, 2) + ":" + bbb(1).Substring(2, 2)
[Code] ....
But whenever an error is detect the user is redirected to another page (errorhandler).I was wondering if it's possible not to redirect the user if the error is of type InvalidCastException .
could u tell me add controls to a page base on user inputs,
i know the basic of creating a button dynamically but here I have to to add few controls based on user input and how to identify event for each dynamically create control.
I think I summed up the question in the title. Here is some further elaboration...I have a web user control that is used in multiple places, sometimes more than once on a given page.The web user control has a specific set of JavaScript functions (mostly jQuery code) that are containted within *.js files and automatically inserted into page headers.However, when I want to use the control more than once on a page, the *.js files are included 'n' number of times and, rightly so, the browser gets confused as to which control it's meant to be executing which function on.What do I need to do in order to resolve this problem? I've been staring at this all day and I'm at a loss.
View 2 RepliesI am developing a page where i have a grid in content page (inherited from master page) which i am populating using DATASET in code behind like this here is the aspx.
[Code]....
As you can see i have some bound fields and one template field called "txtValue" which is the only input in gridview. Now what i want is when user input the value it should check the FACEVALUE and see if the entered value is not above the FACEVALUE and then need to Input value - FACEVALUE and result should be displayed in REMAINING field which is also a template field as label control.
I'd like to create a user control which takes XML as input, applies an XSL transform on it, and displays the results of the transform in the web form or windows form in place of the user control. The transform should happen automagically when the windows form or web form is first loaded. I'd think this would be pretty easy to do. I just don't know how. point to a guide/tutorial on how to do this?
