How To Trigger Certain Methods On Different Aspx Page Using Usercontrol
Mar 3, 2011
I have got 3 aspx page and a usercontrol on each page have an email placeholder in it. What I want to acheive is when the customer click on the usercontrol email placeholder, certain method on a particular page should trigger. See below for the code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Text;
using Tangent.Breakingfree;
[Code]....
Also I have got another method on a different aspx page, I want to trigger that method when the client is on that page. The user control should trigger the right method depending on the page user is currently on.

Is it possible to do something like this inline in an ASPX page?
<%= Me.SomeExtensionMethod() %>
I can't seem to figure out how to get this to work properly. I'm receiving an error saying that "SomeExtensionMethod" is not a member of the current Page object. I've added the necessary <%@ Import Namespace="..." %> directive at the top of my page. This Does work in code-behind.This isn't vitally important, but it would be good to know how to do in the future.

I'm using ASP.NET with VB, and .NET version 3.5. In the project, I've got some utility functions that I call from expressions in the aspx pages and also in code behind. This all works fine on my local machine, but when I deploy to the production server, I get this compilation error on each of those utility methods:
BC30456: 'XXX' is not a member of 'String'.
where XXX is an extension method defined on System.String. I'm baffled about this for a number of reasons:
Why is ASP.NET compiling anything at all, since I've precompiled the application and put everything in the bin directory. ASP.NET knows the functions are there because they work in code behind. It's only when used in the aspx page that I have this problem. (e.g. if I do something like this: <%= "A string to XXX-ify".XXX())%>) This method is public, which I verified with Reflector. I imported the relevant namespaces in the web.config file, and I can see that these namespaces are being imported in the call that ASP.NET makes to the compiler.

i have user controls inherits from base user control like this:
[Code]....
How do i insert CustomerSendMail & UserSendMail into aspx page?
Note: The derived user controls having the same control layout as the base user control. Making copies of ascx page for CustomerSendMail & UserSendMail is not good idea, because if i modify the base's ascx page, the old CustomerSendMail & UserSendMail 's ascx page should be replace with the new one.

I have a problem with calling a method on a aspx page from a usercontrol.
The case is: I have 1 main page with 5 usercontrols, when something goes wrong in the code I want to display the error message in a Modalpopup Extender. I can create for each usercontrol a different modalpopup extender but isn't much easier when I make 1 popup in the aspx page. But the problem is: How should I call a method in the aspx page that open the popup?
I have search several hours on the internet but can't find anything useful.

Senario: Masterpage with a UserControl and a child ASPX page
In the past when using this senario I've used an Interface as a way to pass a value from the UserControl (embedded in a master page) to the masterpage code behind then consume that value in the child aspx page.
My question is now that asp.net 4 have arrived is this still a good way to achieve this or is there another or perhaps better way to do it? I've read somewhere that perhaps "delegates" is perhaps another route to take.

I have two files in my project. One is user control (popup) customerpicker.ascx and one is default.aspx page. In customerpicker I have dynamically generated gridview and 'select' column with SelectButton.
What I want is this: When I click on 'select' on random row in gridview, then I like to display value from selected row immediately (like ajax) to aspx.page. How it is possible?
There is part of my code in .ascx:
public string showOnaspx { get; set; }
protected void GridView1_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
{
GridViewRow row = GridView1.Rows[e.NewSelectedIndex];
showOnaspx = row.Cells[1].Text;
e.Cancel = true;
}
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
GridViewRow row = GridView1.SelectedRow;
//row[i].Attributes.Add("onclick", "$('#ContentIndex_sometextbox).val(" + row[i].Cells[1].Text// + "); $('#Close').click();");
}
I also tried with jqeury (comment in selectedindexchanged function), but it does not work well, because user have to click SELECT two times to effect.

I have MainLayout.master that has UC_Menu.ascx on it.
I have a page named Customer.aspx that uses MainLayout.master. Customer.aspx also contains a UserControl named UC_Details.ascx.
How can I have UC_Menu.ascx call a function that is in UC_Details.ascx with this scenario?
I've seen a few similar examples, but none that match this type of layout.

I have a page that dynamically inserts user controls into a placeholder depending on values in a database table. The user controls consist of a label and one control (dropdownlist, radiobuttonlist, or checkbox). The controls will also have the AutoPostBack property set programmitcally depending on values in the database. My update panel is on the main page, not in the user control. I have tried the ScriptManager.RegisterPostBackControl method to register the UserControl on page load, but the page still does a post back. I think I need to register the control that is inside the UserControl, but I have no idea how to access it from the main page_load event.
This thread is the closest to what I am trying to do, but since I am inserting the user controls programmatically, I need the triggers to be registered programmatically as well. Also, I need to register
them as PostBackTrigger instead of AsyncPostBackTrigger because I need to do a full page reload because the user controls are inserted dynamically.

I need to configure a property of a custom control I wrote, specifically before the control calls OnInit. If I assign it as part of the ASPX file, it naturally works, but if I instead move the assignment to different parts of the code-behind, it will throw an error for having an empty and invalid value. The following is what it looks like when functional in the ASPX page.
<MyCustomControls:SingleCascadeLookupMulti FilterString="Seventh" FilterByStatus="true" ControlMode="New" FieldName="Speciality" EnableViewState="true" ID="sclmDocuments" runat="server" TemplateName="SingleCascadeLookupMulti" />
The property in question is FilterString, which is just a simple string. It should be noted as well that the FieldName property (inheritted from the control's base class "BaseFieldControl") would also throw an error if it is not initialized, but if I set FieldName in the code behind's OnInit method, it works correctly. FilterString is not so, it won't actually be assigned. So I know that some methods for certain properties will work for setting the property's value, but it won't always work. I tried placing it in OnPreInit as well, to no avail.
I am taking a dynamic assignment approach because the functionality of this page needs to be replicated for a number of different lists, and the FilterString and FieldName properties will differ in every case. Rather than write half a dozen mostly-identical aspx pages all with the same code behind but differing just in what those two properties are, I figured it would be wiser to use the page's query string and some derived parameters to set those properties dynamically. As such, what methods are available to accomplish this task?

Ok, this is a bit different scenario. I guess I would have to think about doing it this way sort of with MVC anyway if we were actually using MVC...but we're not at the moment.So I've got and .aspx page. In that .aspx page is a user control (.ascx). And in that user control is a custom control (.cs).
The custom control has a repeater in it. So I'm showing a list of items on that .aspx through the .ascx's custom control. For each item in the repeater is a button. It's just a hyperlink, just a regular on my page When you click that button, it redirects to whatever page you're on. Since the custom control never knows what your parent .aspx page is, I'm doing a redirect to the self .aspx by doing a Response.Redirect(Request.Path). So that way it always redirects to whatever .aspx is using that user control and custom control.
So after it redirects to self, I check the querystring in the page_load of whatever .aspx is using it. If the value is true, then I handle it however the .aspx wants to. In this case when it's true, I call a method in the code behind of my .aspx that handles the action for the button. For example lets say that button was "Add to Shopping Cart", the .aspx handles that action and calls a AddToCart method in the .aspx.cs.
I'm not using an ASP.NET control for the actual hyperlink and button because I just don't need it and in my particular case I'm using a user control and a custom server control.For this instance, I had some issue where I didn't wnat to use an ASP.NET control...I forget why but the point is, no this is what it is.
So with that, I'm trying to figure out how I can apply some AJAX here call to call that method instead. I still need to somehow redirect again back to the same page like I'm doing...I'm doing the redirect in that method after all the logic at the end. I am redirecting again back to the same page, because I need my Page_Load methods in my .aspx and also in an .ascx to still fire off after that method is completed.So I am not sure where to start on this. Let me go through this once again:
Custom control has a repeater in it and in the repeater, each item has a standard HTML hyperlink (non ASP.NET control) which wraps a standard image tag (image is a button)User control contains the custom control The .aspx page contains the user control User clicks the butt on and hyperlink redirects them to the parent .aspx page that is using this custom control...so it callsResponse.Redirect(Request.Path)
In the code-behind of this .aspx, in my page_load I check a querystring flag to see if I performed that action..meaning user clicked that button. For example one of the querystring params is "AddItem" and another querystring param is "itemID". If movedItem is true, then I fire off a method called MoveItem(int itemID) Method MoveItem is called Method MoveItem redirects again back to this same .aspx using Response.Redirect(Request.Path).. this is so that the page load is hit again as well as my .ascx page load is hit. Because in both those page loads, I rebind a repeater so I can show the latest state of the lists. I call a method in my .aspx page_load which rebinds a grid and then page_load in my .ascx also calls another method which rebinds some other list

Is that possible? The reason why am doing this is because I need to parse that variable into a an JQuery function so I wanted JQuery to read that field. Can I Assign that value in base class or I have to do it within default.aspx pageload method?
