Dynamically upload and use usercontrol at runtime

Posted By:      Posted Date: October 09, 2010    Points: 0   Category :ASP.Net

Hi All,

I was wondering if it is possible to upload the  .ascx and .ascx.vb of a custom usercontrol into my project directory at runtime via an upload control and then after that use through a database query point my page to load that newly uploaded control via (LoadControl(<newlyUploadedControl>)?

Please kindly advice and assist.

Thank you in advance.

Warmest Regards,

How to load a usercontrol xaml at runtime ???????

Hi, I have a usercontrol xaml created in Expression Blend. Similarly i have xaml for other usercontrols as well. Now i want to draw these controls at runtime on click of buttons, the way it works in VS IDE (Toolbox and Drawing area) Is there any way to load such usercontrols on Canvas at runtime ? What would be the best way to load controls at runtime ?      Programmer

usercontrol layout in canvas at runtime puts in mult. copies of 1st element in collection.

I created a usercontrol which has a few DP's that match up with fields in a sql table. The requirements of this control specify if I get a specific status value I will flash the usercontrol to draw attention to a specific area of equipment in the facility. I also provide a tooltip which has all the fields of data to view. The usercontrol should only display it's description. On a button click I run the following code which instantiates a new observablecollection of my custom usercontrol (I call it profiNode). It then fills a dataset by calling our DAL and then I loop through the datarows using the values to create a new profiNode object for each row. I then add these to the observable collection, but I suppose a generic list would work too.     ProfiNodes = new ObservableCollection< profi.profiNode > (); DataSet data = new DataSet(); data = this.DataLayer.getDataSet("Select * from ProfibusMapping", CommandType.Text, null); foreach (DataRow row in data.Tables[0].Rows) { profi.profiNode node = new profi.profiNode((string)row.ItemArray[0],(int)row.ItemArray[1], (int)row.ItemArray[2], (int)row.ItemArray[3], (string)row.ItemArray[4], (DateTime)row.ItemArray[5], (int)row.ItemArray[6], (int)row.ItemArray[7], (string) row.ItemArray[8], (double)row.ItemArray[9], (double)row.ItemArray[10]); node.ID = string.Format("node_M{0}_A{1}&q

DataView upload save file goes nowhere. How do you set a folder to upload to? Dynamically?

I have a Dataview bound to Document Library with the New Document button enabled. It apears to upload but can't find the files anywhere. I don't have a Shared Document folder. How and where do you set where to upload the file? A specific folder would be nice and If I could make it dynamic tied to QueryString Ideal. Going a bit further, the library I'm bound to has many 3 digit numeric folders that are dynamically created when entries are added to another list. The page that is calling my dataview has a querystring that will tie into the folder I want to drop files into. Just wondering how I can dynamically set the upload destination. Currently this is the generated code: <input type="button" value="Save" name="btnSave" onclick="javascript: {ddwrt:GenFireServerEvent('__commit')}" /> <a href="javascript: {ddwrt:GenFireServerEvent('__cancel;dvt_1_form_insertmode={1}')}">Upload File</a> I have some other code that calls the classic file upload page that is working perfectly, but I'd really prefer the clean and simple UI of the DataView control if I could make it work. Thanks!

How to drag UserControl during runtime

Handling button clickevent in Usercontrol that is being loaded dynamically


Hi I need some ideas to do this:-

I have ASPX page named  ArtifactReporting.aspx where I have 3 linkbuttons. For each button I have 3 different UserControls to be loaded dynamically. So I have written for each click

UserControl uc = (UserControl)this.LoadControl("<ASCX page name>");

Now in one of the ASCX page I have a server side button. When I click on the button, the content of the ascx is going off, which is correct, because the page post back is happening and in Page_Load I have not written anything that will load the ASCX page.

Can anybody give me an idea on how to go about this? I need if I load an usercontrol dynamically, I should be let the users carryout operation that usercontrol.

Problem setting endpoint address URL dynamically at runtime in client


I have a WCF web service and clients running on separate windows server 2003 machines. I'm using windows integrated authentication to authenticate the clients. All of the clients and the service are running in appPools in IIS6 as specified active directory users. I have added the service as a service reference to the client project in Visual Studio 2008. This works fine in the development network. To run it in the Production environment I need to change the URL and the UPN at runtime to the production values, but whatever I try it just throws errors? In fact the only thing that worked - but isn't really practical - is when I removed the development service reference and added the production service reference to the project using Visual Studio before deployment. Surely there is some way to change the endpoint at runtime??? I must be missing something simple. Please help! :)

Here is the relevant part of the client endpoint:

         < endpoint address ="http://dev.happyfunland.com.au/FunService.svc" binding ="wsHttpBinding"

Dynamically Generate a WCF Proxy class at runtime and Callling web methods via reflection



I'm busy writing an application where the user will have to specify the location of a ?wsdl file for asmx and/or svc type services.

My application will have to :

1. Deduce from the wsdl what methods (with parameters and return types) are available on the service.

2. Provide a way to either generate a Proxy class in memory to execute methods against with e.g: Reflection

    for instanse : genericProxy.Invoke("HelloWorldMethod",parameter1,parameter2);

    I want to avoid using something like this : notSoGenericProxy.HelloWorldMethod(parameter1,parameter2); seeing that my application will have no 

    idea what service it will have to work with at runtime.

Is there a way to achieve this?

Thank you for any help in advance!

How to Localize Windows Forms and Change the Language at Runtime

Localization is the process of customizing your application to a particular language, culture or locale. Visual Studio provides support for localizing Windows Forms with much ease. In this article, we will see how to localize windows forms and give the user the ability to change to his preferred language at runtime.
When you run a localized application, the appearance is determined by two culture values. The UICulture property is used to specify which resource files will be loaded for the form. The Culture property, on the other hand, determines how strings such as dates, numerals, and currency amounts are formatted.
Let us see the steps required to create a localized form. You can then expand this example and adopt the same approach for the rest of the forms in your project
