Web Forms :: Usercontrols - How To Add Intellisense Value Choices To Parameters
Nov 9, 2010
I have a general question regarding usercontrols' parameters. In the built in web controls, such as the 'runat' parameter, when you begin to type 'runat' in Visual Studio, it gives you an Intellisense choice of 'server'. Or in the RequiredFieldValidator controls, the 'Display' parameter has 3 choices: Dynamic, None, and Static.
My question is, how do I incorporate this feature into my custom Usercontrols?
For instance, I created a usercontrol with a parameter called 'BorderColor'. This parameter will change a textbox's border color to the specified value. The possible values are: Blue, Red, Green, Black, Purple, etc. How do I have Intellisense display these choices when the BorderColor parameter is typed in?
I think my main problem is actually more to do with master pages that anything else.. Below is a description:
If you use master pages in your website and you have pages in different sub directories then the simplest way to add JQuery references is using <script src='<%# ResolveUrl ("jq.js")%> /> in the master page header??
This means that the .js files are correctly referenced in all pages that use the master. My main problem is that intellisense only seems to work for JQuery when the JQ Script is actually referenced in the header and not by using ResolveUrl('') <script src="/scripts/jq.js" />
I dont want to have to live without intellisense, Surely there is a way to get around this. What am I doing wrong.
I am working on an ASP.net Forms Application that keeps track of information about different offices in an organization. The offices are organized into a hierarchy.
Some users of the program will have access to certain information about all offices in the hierarchy. Some users of the program will have access to only a small part of the hierarchy.
When a user browses for information they are authorized to see, I would like to present the user with a prompt to choose which office in the hierarchy they wish to see information from.
I want to accomplish the following:
A) I want the user to be able to easily navigate the hierarchy of the organization to locate a specific office.
B) I want the user to be able to navigate the hierarchy without refreshing the page.
C) I want my interface to be able to handle a hierarchy at least four layers deep with less than 100 nodes.
I see that Microsoft includes a TreeView control in the standard collection of ASP web controls.
I am using AppCode and have 6 arrays of information I want to display on my web page. However I only want three to be visible at any one time. ________________________________ | | | | | | | | ________________________________ button button button
i.e. a table like the above.
I have created the layout and the choice buttons etc I am using querystrings to pass the changes to the webpage.
The problem comes however when trying to write the code for the table diplay. Now each has a slightly different layout.
My initial thought was to write a function within the aspx/html page for each table, then in each column of the master table one of the functions can be called to populate it. Each of the functions will contain the HTML tagging for that information. However I dont seem to be able to achieve this as when I try to right a sub or function it doesn't like it. I have also tried to write the functions into the code behing but again this didnt work.
Alright, I am completely baffled by this one. When filling out this page in IE8, it will SOMETIMES clear all entered data (including radio choices) when you select Yes, No, or Not sure (line 892 in the code). This is a postback question, as it should potentially show more questions. This problem does not happen in any other browser, and rarely in IE8. I have no idea what is causing it, the code I am using has been used in similar applications and I can't find any change which results in this behavior.

I have a combo box that looks great in the designer, the list of choices are perfect. But when I view the ASP code, or the published webpage the choices are seriously garbled. I have tried adding items, but it does not seem to regenerate the code. Any ideas why it happened and what I should do? I do most of my editing through the designer GUI. Note the blank items and even items mixed up together: TVCricket
asp Code: <asp:DropDownList ID="ddlFoundOut" runat="server"> <asp:ListItem Selected="True">(Pick how you found out about us)</asp:ListItem> <asp:ListItem>Another Store</asp:ListItem> <asp:ListItem>Banner at Arena</asp:ListItem> <asp:ListItem>TVCricket</asp:ListItem> <asp:ListItem>West NewsmagazineClear</asp:ListItem> <asp:ListItem>Driving By</asp:ListItem> <asp:ListItem>Friend/Co-worker</asp:ListItem> <asp:ListItem>Internet</asp:ListItem> <asp:ListItem>Mall Sign</asp:ListItem> <asp:ListItem>Online Phone Book</asp:ListItem> <asp:ListItem>Phonebook (paper)</asp:ListItem> <asp:ListItem>Radio</asp:ListItem> <asp:ListItem></asp:ListItem> <asp:ListItem></asp:ListItem> <asp:ListItem>Other</asp:ListItem> <asp:ListItem>Other Magazine</asp:ListItem> <asp:ListItem>Other News Paper</asp:ListItem></asp:DropDownList>
On this page: http://vucsyd.dk/kursus/web/TilmeldingEksamenTest.aspxe.g. student number: 10629 kan mark rows and make choices in dropdownlistsBy next visit i i would like the page to show earlier choises. Do i have to change everything or is there an easy option?Site code:
That out of the way, here's my situation: We are looking to port our existing classic ASP application to .NET, but we're unsure of what language to use for the new app.
I personally would 'prefer' C#, as I'm more familiar and comfortable with that languages way of doing things, but, the original code is VBScript, so it would possibly be easier to port to VB.NET ... One possible situation I fear would be that, because the code is so similar between the two variants of VB, that we might end up getting stuck on something that is not similar between the two, even though it looks like it would work. A shift to a wholly different language might avoid that kind of situation.
Does anyone have any practical examples of this kind of situation? Insights to illuminate the issue with? Do the potential benefits of a complete paradigm shift outweigh the gains from a high degree of 'copy-and-paste-ability' ?
I'm not expecting a full solution here (unless you really want to), just some tips and pointers.
I have a User table and an Area table. The User table has userID, userName etc., and the Area table has areaID, areaName etc.
I'm binding the list of Areas to a checkboxlist where the user MUST choose between 1-3 options. I'm using a stored procedure to update the DB.
Is there a common solution to this problem that I haven't found?
I have thought about saving it as a comma separated string in a field in the user table. This looks like a temporary and ugly solution though, do you think?
A nicer solution would be to create a UserArea table where I save the ID's as foreign keys from areaID and userID. But I don't know how to write this stored procedure where I update and insert the choices made.
I want to bind a field in a View to a property in a ViewModel. The object is "Program" and has the properties "Name" and "Level". So the user should be able to set the name of a program and the level of experience he/she has with this program.Program is a table in an Sql Server database, and is accessed through Entity Framework. So it would be easy enough to bind the Level property in the ViewModel to a textbox:
@Html.TextBoxFor(model => model.Level)
But I want a dropdownlist with a limited number of levels (1-5). So how do I do this and still have the dropdownlist bind to the ViewModel property?
If I want to be able to have a table Consultant, which is the user and their personal information, and I want this user to be able to select their proficiency in a number of Programs (software) on a scale from 0-5 (zero being no experience whatsoever), how do I do this best?
I mean I could have a Consultant table with a one-to-many relationship to a Program table, and then have all the limited Programs availalbe loaded by an XML file or something, and for each Consultant associate all the Programs and their Levels of proficiency. But that seems very wrong and inefficient.
It seems to me I should have a table with all the (limited number of) Programs, and then by some sort of association between the two by Ids. But I can't get my head around how to do this. I'm thinking many-to-many... But first, is this correct? Secondly, how do I do this in an Entity Framework Model? I usually create my database code first, i.e. create the EF model, and then generate database from model. Will I get a junction table where I can add the Level field, because basically a Consultant HAS A Program with a Level, or actually a list of Programs each with a Level.
I'm creating my first server control, and have it working where I can set up an enum and the user can set a property's choices, based off of that enum. But I'd like it to pull records from a database and populate the list of choices for the property from a database. This would allow me to add a new "Host System" to the database, and the other designers wouldn't have to get a new copy of the dll.
In one of my pages I use an usercontrol. The usercontrol has a textbox and a button on it. When someone adds text to the usercontrols textbox, I want to use the entered text in my page_init event. The problem is that in the page_init event, the textbox value is empty. How can I use the entered text in the page_init event?
I have several dynamic usercontrols that I want to load them in separete tab panles.but my problem is when the postback occures my usrecontrols diapeare.however I want to keep my usercontrols in each tab panle in each postback.I mention that I write code in c#.
We need to add 2 user controls to an aspx file, these 2 user controls have one telerik ajax manager each. but telerik only allows one ajax manager in a web page. I am getting exception while running the app.
Is there any way in aspx to seperate the user controls so that it will act as a seperate page?
First off - has any recent .NET / Windows Service Pack / Windows Update changed the behaviour around the Visibility of Panels / User Controls? An area of our site has all of a sudden stopped working. The most recent change that I made was a few weeks ago, I've backed out the change from my development environment, but the issue is still happening.
I'll explain what is happening. I have a couple of forms where the same behaviour is happening, but they follow the same pattern:
On the form there is let's say 2 ASP:Panel controls. In each of these there is a separate ASP:UserControl. When the User first visits the page, they are shown the first Panel and User Control. On this control they complete a couple of steps and click Next. This fires an event on the main page, which hides the first panel and shows the second panel, at least that is what is supposed to happen - and if I debug and step into the code this is what is happening as normal. Except on screen, the first panel is no longer being hidden, so it would appear clicking the Next button does nothing.
I'm at a loss as to what has happening - nothing has changed, and stepping through the code it's working correctly, but the screen is not reflecting what is happening in the code.
My next step is to create an isolated set of test pages to recreate the issue. Will attach when done and investigated, hopefully this will solve it
I have implemented a user control with dropdown lists and textboxes where user may choose to add more of the same user control dynamically then submit the values within all usercontrols at the same time. They way I added usercontrols dynamically is whenever user clicks "add more" button, it increases the value of "userControlAmount" in session by 1, reloads the page and during next page_load event, within an updatepanel it creates usercontrols on the fly.
However whenever more is added since all usercontrols are generated again according to the latest user control counter, the values within the dropdownlists and textboxes are getting reseted.
I can hold all values in a viewstate/session however beyond the time/effort it will take, it doesn't sounds very "professional" to me. I was wondering if there is a more efficient way of doing this.
I was trying to add a Theme and some UserControls to a existing ASP.NET Web Project (nopCommerce) via a Second Web Project (which is added as an virtual Directory). But this did not work in my Configuration and I did not know if this is even possible.
The Reason why I want to seperate my Code from the nopCommerce project is for easyer upgrading to a new Version, and to handle adaptations for different shops efficient.
I have the usual problem of dynamically created usercontrols not hitting the event handler for a linkbutton inside the control, but I've checked the usual problems and I can't work out what's wrong. I'm calling a function to create the controls at the bottom of my page.load (although I did try page.init as well just in case) outside of my page.ispostback check, and I'm setting the controls id's to a fixed name which is consistent across postbacks. Any ideas what's wrong?

Usercontrol code:
<asp:LinkButton runat="server" ID="lnkDeleteGroup" Text="Delete this group" />
I have a simple user control which contains a textbox and a dropdownlist. I need to add this control multiple times to my page then save the details to my db, validating each control. When they re-enter my page I need to load the user control for each record in the db populated with the data they entered. They can then edit the data, delete the row or add new rows.
I'm trying to find the cleanest most efficient way to accomplish this. I realise I would need to re-add the user controls after each postback re-populating the data. Would the best way be to add each row to an arraylist or list of type object, save it to the viewstate and re-add the controls with data on postback, or is there another method which would suit?
In my web application , I have an online application form which contain 4 sections.When I click next button in the first usercontrol for the first section,i need to display the second usercontrol for the next section. When i tried, first loaded usercontrol only applying the styles.
what logic i need to use here to display each usercontrol on the next button click. How to save the values of each usercontrol on the next button click?
I have a userControl with with two DDLs and two RBLs, and public properties to get/set the values. If I register the UC on a page it works fine....I can set/retrieve the values without a problem.
I need to create multiple UCs based on records I'm pulling from a dB, so I'm trying to instead create the UCs programmatically. I'm testing this by adding a reference to the control ("symptomBasic"), creating a placeholder ("ph1") on a page and then trying to populate it with the UCs in PageInit. (the parent page uses a master page)
Partial Class testUC Inherits System.Web.UI.Page Private myUC As ASP.symptomBasic Protected Sub Page_init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init Dim i As Integer For i = 1 To 3 myUC = CType(LoadControl("~/controls/symptom.ascx"), ASP.symptomBasic) ph1.Controls.Add(myUC) Next End Sub Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load End Sub End Class
When I load the page, I get three UCs in a row, and they work properly on postback...i.e. all the values are preserved. Question is, how do I then find the controls on postback when I want to populate them with data or read the values back?
Let's say I know I returned 3 rows from the dB and created 3 UCs during pageInit...how do I then access those controls to read back the values provided by the user? I see that each control has an ID like: "ctl00_ContentPlaceHolder1_ctl01_cName", where each set of controls is "ctl00", "ctl01", etc.
