I was wondering if I could add a user control to a page with a parameter and then access that parameter in the code behiind for initiallization.
For example on my aspx page i would have somethign like.

I'm building form validation controls for our C# ASP application. The bulk of the work is handled by a BaseValidator control (subclassing System.Web.UI.UserControl), which also has the markup for the validation output. This is then extended by subcontrols like PasswordValidator, that provides the Validate method and any extra fields needed by that validator control.
(The end goal is to have controls like <uc1:PasswordValidator ControlId="txtPassword" /> which we can plop into any form with minimum duplication.)
However, PasswordValidator.ascx.cs cannot access the form elements defined in BaseValidator.ascx; the only way I've found to do so is to duplicate the markup in each subcontrol's *.ascx file. How can I extend BaseValidator.ascx.cs and access BaseValidator.ascx's markup in the subclass?
I'm using a user control which uses a dropdown. I call a parameterized stored proc to to populate it. I don't know how to pass parameter '_ReportName' from main aspx file to ascx file.
HTML Code:
<asp:DropDownList ID="dropSortOptions" Width="200px" CssClass="Dropdown" runat="server"
DataSourceID="sqlDataSource" DataTextField="Option_Desc" DataValueField="Option_ID"
AutoPostBack="True">
</asp:DropDownList>
<asp:SqlDataSource ID="sqlDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionStringName %>"
SelectCommand="sp_SortOptions" SelectCommandType="StoredProcedure">
<SelectParameters>
<asp:ProfileParameter Name="ReportName" PropertyName="_ReportName" />
</SelectParameters>
</asp:SqlDataSource>
how can i access a public function in an .ascx file using C#?
View 3 RepliesI've got a simple ASCX user control (non-MVC). The user control has a property on it (let's call it Title or something).
I've also got an MVC Partial View which contains the user control.
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<SomeModel>" %>
<%@ Register TagPrefix="tag" TagName="Control" Src="~/path/to/ascx/control.ascx" %>
... snip ...
<tag:Control ID="myControl" runat="server" />
What I'd like to be able to do is something like this:
<tag:Control ID="myControl" runat="server" Title="<%= Model.Title %>" />
... so that I can access some property of the model inside my Control.
Unfortunately this method doesn't work, as I get a message saying "This is not scriptlet. Will be output as plain text".
Is what I'm trying to do even possible? If so, how I can try and do it?
If it's relevant, this is a .Net 4 project, with MVC 2 components.
I have a function that Localize the text of my control.
// code behind
lblName.Text = Localization.GetLocalValue( "Updated" , this.Path );
and I know that i can call a function inside ascx file.
// ascx file
Text='<%#Global.Convert( (DateTime)(Eval("CreatedDate")) %>'
How can i Get Path Property in ascx file To call GetLocalValue ?
I have a master page with a ascx control I use for a header. There is a label in HeaderControl1 I need to set from the content pages. I was able to make the changes in the master template as a tes by just calling the control and accessing the property.
HeaderControl1.txt = 234

I have a basepage class which holds a bunch of properties, and specifically a context reference to entityframework
I have a standard .aspx page that inherits from the base page like so
public partial class myinterviews : BasePage
I have a standalone .ascx page, it has a grid and a datasource. This .ascx page is apart of the .aspx page that inherits from the base page. How can I reference the methods, properties from the base page from within my .ascx page?
I have a code to link to sql can anyone give me the same code for microsoft access....

I have a variable in an aspx file I need to use/recover it's value into an ascx web control that's in this aspx file. It's possible to do it? The aspx dynamically loads web controls depending the scenario, so this web control not allways is loaded.
View 2 RepliesI am building a library of asp.net user controls which I am deriving from a custom UserControlBase class which further derives from actual UserControl class. Hierarchy looks like this :
ASCX -> UserControlBase : UserControl
I have this requirement to put a border around all the ASCX's. So, I thought if I can modify UserControlBase it will apply to all ASCXs. I tried following code in Page_Load of UserCOntrolBase but its not working
Code:
this.Attributes.Add("style", "border-color:#FFFF66;border-width:4px;border-style:Dashed;");
What should I do to make it work?

Not sure which category to put this question in, so I will put it in here. Just to give you an idea of the layout of my solution, I have the main project, along with 2 class libraries, BLL and DAL. (Business Logic Layer and Data Access Layer) The BLL refers to the DAL and the main project refers to the BLL. I had a test website and the code worked fine, but the same code will not work on the real project. The only difference is that in the test project, the code was on an aspx code behind, whereas in the real project, it is an ascx code behind (Web User Control
)
The code is:

Dim connectionString As String = ConfigurationManager.ConnectionStrings("ASPNETDBConnectionString").ConnectionString
i'm having problems with this. I am developing an asp.net mvc 2 application. I have a partial view menu.ascx defined. this gets included on all the pages of my site in the Site.Master masterpage. Now the thing is I want my menu to change according to the type of user.Here's what I did at first:
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<dynamic>" %>
<li><%: Html.ActionLink("Home", "Index", "Home")%></li>
<% [code]....
I shouldn't be doing this in the view ! But since this is the MasterPage no controller actually calls it so I don't know where to put the info in the ViewData dictionnary or ViewModel to pass it to this masterpage.
I created a GridView in code with a DataTable as its data source which worked fine. I have now moved the GridView creation into a .ascx file to make it easier to format.
For some reason this has started triggering the HttpParseException:
Databinding expressions are only
supported on objects that have a
DataBinding event.
System.Web.UI.WebControls.HyperLinkField
Original code:
// Set up columns for datagrid
var boundField = new HyperLinkField

I have LinqDataSource ID="LinqDataSource1" with values - EnableDelete="True", EnableInsert="True" EnableUpdate="True" on my ascx page, furthermore GridView, button a few textboxes, where a fill new values, which I would like save in my database. After click on button I insert new value to the table throught in function stored in ascx.vb page. It is works, but I don't know, how I refresh GridView on ascx page. I tried
LinqDataSource1.DataBind()
GridView1.DataBind()
without any good result, I must refresh page manualy (F5).
I have a user control (ascx) which contains a control (hidden field). In the page_load event of ascx, i have the below code:
HyperLink.Attributes.Add("onclick", "JavaScript:return AccessControl('" + hdnField.UniqueID + "');");
Note: The hidden field resides in .ascx file.
I want to access this hidden field at runtime and i have the below javascript function in aspx page that loads the usercontrol.
function AccessControl(hdnFieldId)
{
var ctrl = document.getElementById(hdnFieldId);
alert(ctrl);
I am getting 'null' value in the alert. I tried using 'ClientID' and 'this' instead of 'UniqueId'. I am wondering why this is not working. I am using .net 2.0.
You've probably noticed that when you debug an error which comes from an ASPX or ASCX file (literally, not from a corresponding code-behind file), ASP.NET displays an error page showing you the source file and the line on which the error occurs. The source file being displayed is automatically generated from parsing the page/control. The question is: how can I see this source file without purposely causing an exception?
I'd love to hear that there is some programmatic way (the complexity doesn't matter) to generate source files (preferrably, .cs) from a series of ASPX/ASCX files.
Example. Consider the following ASPX page (the code-behind file may even be absent):
<%@ Page Language="C#"%>
<%@ Register Assembly="AspxGen" Namespace="AspxGen" TagPrefix="ag" %>
<html>
<head><title>Some Title</title></head>
<body>
[Code]....
d:DevAspxGenAspxGenDefault.aspx(9,80): error CS0103: The name 'ThereIsNoSuchProperty' does not exist in the current context
This means, theoretically I can open the .CS files passed to the compiler (namely, App_Web_sqj3krv3.0.cs and App_Web_sqj3krv3.1.cs) and see what ASP.NET has generated from my ASPX markup. Trying to rephrase the previous question: how can I obtain this file from an arbitrary ASPX file (assuming that the file is correct and hence no info will be given on where to search)?
I am working on a feature to throw a warning message if the user has unsaved values in a form. I can see that in the next post there is a explanation about how to do that [URL]now the problem is that i need to do the same but using a ascx control and i don't know where put the next code in my ascx control.
<body onunload="checkSave()">
NB: I'm working on dnn so that i don't have any change to add this code in the parent page of the control.
i have two buttons, which point to some onclick-methods in my code-behind file. inside these btn_click-codes i want to start adding pure html-code to my page, which was told to me in this forum having done by using ascx-files. note: there would be no code-behind in case of using the ascx-files.
however i do not see a possibility to load these ascx-files within btn_click-code? how to do?
in order to give you an idea of my html-code i have pasted two of them here:
[Code]....
maybe this is the complete wrong approach (as i.e. i believe that body-tags should not be included in .ascx-code). in this - how to do better?
I have to build a few ascx partial views in my MVC applications to encapsulate re-usable functionalities as well as archive SOR and SOC. However, I encountered challenge how to encapsulate the business logic that drives MVC ascx views.In webforms, the code behind of an ASCX control can handle a button click event and browser still shows the same page with only one postback. How can I archive the same thing in MVC? When ~/Address/Edit/2 includes an ascx partial view with a button on it that calls another MVC action - let's say ~/ShareController/CommonAction - what is the best way for the CmmonAction to return to the very same view that includes the ascx file?Perhaps I am missing a common pattern in MVC web development?
View 5 RepliesI'm using vs2010, asp.net 4 webform.Is there anyway which i can update a code behind file (ascx.cs) file without compile the whole site.because i just want to debug some ascx.cs file, and compile a big whole site will cost 1 minutes at least.
View 1 RepliesI was just editing some C# code between <% %> tags in an .ascx file, and I noticed that the Refactor contextual menu is unavailable. And even if I manually add items from this menu to a custom toolbar, they are disabled when viewing aspx/ascx files.
I usually only have small snippets of C# code in my aspx/ascx files, but it would still be nice to be able to perform refactoring operations on any code that exists between <% %> tags. I feel like I'm going back to the dark ages when I have to use find/replace to change the name of a variable.
Questions
Is there a way to enable Visual Studio's refactoring features while viewing aspx/ascx files in Visual Studio?
Are there any Visual Studio plug-ins (preferably free) that offer this kind of functionality?
I am having difficulties how to construct my question, but if I have to put it simply the situation is that I have categories of products. I have an aspx with a repeater on the left that lists the categories. And I want the products to be listed on the right. Category number is variable so I made an ascx with a DataList in it. When I try to do foreach category, ascx = new ascx(); then the DataList within this ascx control is null.
ps: what I want to do is to preload all the products (thre is not much) and hide the divs and fadein fadeout them using jQuery when a category div is clicked.
rightnow it is using jQuery.load(); and I don't like how the images load, cuz they download from top to bottom. Progressive gifs alsdo not an option. site demo is here [URL]
I am not sure how to pass a variable from an .aspx page to an .ascx page. I have a Control that puts rotating banners on a page. The control has several public properties. However, only one of those properties changes on the page level. All the other properties are the same for every page site-wide. So, instead of setting all the properties on every page in my sites (many sites), I want to set it up so I only have to setup the sitewide properties once and only the page level properties on each page.
I want to create a control with a property of AdKeyword="somename" and pass it to another control that will grab that page-level property and add it to all the other site-wide properties. I guess what I need could be called a Dynamic Control Property.
My .aspx page has:
[Code]....
[Code]....
Now, how do I pass the "OverrideHeight" parameter to the "uc1:banner" control on the banner1.ascx page?
I tried binding the parameter with a
[Code]....
string in the control. But, that did not work.
