C# - How To Display A List Of User Controls In WebForms
Feb 16, 2011
This is not really a question so I hope don't be fired! So I have to make a twitter like timeline, a superposition of blocks containing informations.
I really don't know how to make this.. The problem is the number of blocks aren't the same each time, sometimes it will be 1 block only, sometimes two or sometimes more..
So do I make some HtmlWriter to write the html directly? I pretty new in asp.net so maybe it is possible to do that more easily! With WebUserControl maybe, a block = a wuc so I can add the number of wuc I need.. I'm quite lost so maybe somebody have done this kind of thing already and can put me on the right way..
I am developing small social networking site using asp.net & c#.I want to display friend list for each user. How can I do this task using java script? or there is any other way to do this task?if possible then show some demo code or example.
For a large fillin form I use the asp.net FormView for the magic databinding to my model. In this model I've a property called Rides (shown below), which exposes a list, which I obviously not want to be replaced entirely. So I made it readonly.
However, this way I can't use the databinding features anymore. Is there a common solution for this problem?
I have a GridView which I have a List bound to - I want to be able to allow filter of the data based on multiple CheckBoxLists. For arguments sake let's say I have a List of Jobs, and I want to filter the jobs by code - So I would have a CheckBoxList likeC#ASP.NETphpF#etc..If someone selects multiple codes, how do you pass the values into a List to rebind to the GridView? Is there a way to pass values as an array? Or maybe a comma seperated string?Any examples (I'm a C# boy) would be greatly appreciated, and I hope I have explained it properly :S
I would like users to upload a profile picture when they register, and to then show that picture in a picture box control when they are logged in based on that specific user.
I have started using jquery in one of my new asp.net webform application... I want to display a success message after an insert on a button click event... Here is my link button..
i want to use dataset , or any thing ... to display Sum * where user= user.identity.name(not use gridvew, or formview) because i have more then 100 columns . i m newbie. realy , 1 month, it not solve, sometime , i want to give up
I have one application form in which i want to store image of student with enrollment no and when i submit i want to store that image and take that image on another page on submit button two things should be done
1. storing the image and enrollment no 2. passing enrollment no and image to another page
I am making a Human resource Management system in which i have to make employee profiles, there is a page in which i am entering employee name and uploading a rofile picture and i want the next page to show that image on a left corner of every employee...after clicking on the submit button of the previous page !
I have an aspx page that I would like to have injected a reference to a user control. The user control is stored in a seperate assembly and loaded at runtime. After injected the user control it should then be loaded into the control collection of the page.
Everything seems to be working fine expect the point of adding the control to the page. There is no error but the UI for the control doesn't show.
global.asax.cs
protected override Ninject.IKernel CreateKernel() { var modules = new INinjectModule[] { new MyDefaultModule() }; var kernel = new StandardKernel(modules); // Loads the module from an assembly in the Bin kernel.Load("ExternalAssembly.dll"); return kernel; }
and here is how the external module is defined in the other assembly:
public class ExternalModule : NinjectModule { public ExternalModule() { } public override void Load() { Bind<IView>().To<controls_MyCustomUserControlView>(); } }
The debugger shows that when the app is run, the Load on the external module is being called, and the dependency gets injected into the page.
public partial class admin_MainPage : PageBase { [Inject] public IView Views { get; set; }
At this point when trying to add the view (here a user control) to the page, nothing is shown. Is this something to do with the way the user control is created by Ninject? The loaded control seems to have an empty control collection.
inside aspx page
var c = (UserControl)Views;
// this won't show anything. even the Control collection of the loaded control (c.Controls) is empty var view = MultiView1.GetActiveView().Controls.Add(c);
// but this works fine MultiView1.GetActiveView().Controls.Add(new Label() { Text = "Nice view you got here..." });
and finally the view/user control:
public partial class controls_MyCustomUserControlView : UserControl, IView { }
It contains just one label:
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="MyCustomUserControlView.ascx.cs" Inherits="controls_MyCustomUserControlView" %> <asp:Label Text="Wow, what a view!" runat="server" />
I get the above error when trying to run my .net app as it attempts to connect to a SQL database on another server.
The SQL connection string is using a trusted connection. IIS has anonymous access switched off, and integrated windows authentication switched on.
The user the error relates to is "DOMAINNAMEIISSERVERNAME$"
Do I need to add user "DOMAINNAMEIISSERVERNAME$" as a login on the SQL server machine? I expected my username to be passed around - i.e. if I have access to the SQL server then the application would run fine?
EDIT: Should point out that I know it's authenticating OK from an IIS point of view... if I switch to anonymous access it fails my own security as an "Unknown User"... which is what I'm after
<script type="text/javascript"> function ClientTime() { var dt = new Date(); var ss = dt.getSeconds(); var mm = dt.getMinutes(); var hh = dt.getHours();
How can i generate dropdown lists based on what has been selected in the checckbox list. Below is an example of what i need. if the user selects the options day, lotID and waferID, then 3 cascading dropdown lists should be displayed. And then a gridview displays data based on what has been chosen in the dropdown lists.
Day LotID SlotID WaferID VendorID ToolID LocationDetected ProcessStep Stage Precipe WaferStartMaterial WaferStartVendor WaferStartLot WaferDiameterCOA WaferMapTitle BreakPoint BreakpointSide BreakpointMeasurement
Now I want to attach to the click-event of every single li-element, so that if the user clicks on a div-element, detailed product-informationen should be loaded asynchronously into a details-pane. I know how I can use jQuery to invoke an action-method ajax-style and also how to display the json-result which contains the product-details, BUT I have no idea, how I could attach the onclick-event to every single div, so that I can use the productId to load the details.
I'm trying to display a list of images in the View. I have a list of URLs (List<string>) that I'm passing from the Controller using ViewData["imageURLs"], but nowI have no idea how to generate and display them?
i am creating a dataset from SP Sp when executed in query analyser dislays the output but when i used the same for creating datset , its created but i dont get any columns i checked the xsd in notepad but there is no column source names
I am looking at how best to prevent a single user account logging on multiple times in a webforms application. I know that MembershipUser.IsOnline exists, but I've read a few forum and blog entries suggesting that this can be unreliable, particularly in scenarios where a user closes a browser (without logging out) and attempts to logon with a different machine or browser.I looked at implementing a last past the post type system; when a user logs on older users are simply kicked off. It seems that FormsAuthentication.Signout() only works for the current user.
Am using update panel in my .aspx page .when i change the value in drop down list inside the update panel am getting the following error. am not using any response object or server object in my code.
"Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error ...."
I'm creating in my code a list of object which must be displayed later in a table.
In Winforms I'd simply bind the DataGridView to the list, and everything is fine.
However, when I try to set the GridView's data source to the list, nothing happens, and I can't find a way to do this with any of the procided data sources(Such as ObjectDataSource, etc.).
I have web form and on it I have a DataList that is grabbing some Data from a Database and displaying them as a list.However when I look at the HTML Source Code produced, it's all Tables ! <td> and <tr> !!
How can I stop this ? I want my DataList to display the data like so:
I have a problem with binding a DropDownList. Let's assume a database five years old with many historical records. In order to enable just working with active data every datasource has a column hidden which is occasionally set by administrator in order to clean up old records. The selection looks like
1) SELECT Id, Value FROM Table WHERE Hidden = 0
The issue arises when the user opens a form with old data. As some records in DropDownListhave have already been hidden an exception is raised as the component cannot find the data for the list. For this case the following selection is valid
2) SELECT Id, Value FROM Table
it is possible to combine these two selection queries? The display value should always use query 2 while the listed values should use the query 1.
