I have a table that displays a user control on each row. The user controls are strongly typed to a viewmodel which contains DataAnnotation style validation. If one of the rows has invalid data entered (lets say the 3rd row) the data annotation validates display agains the first row/user control.How do I get the data annotation to show against the relevant user control?
View 1 RepliesI'm trying to include a user control in an aspx page, it works fine, but my control does position itself where I want it and always appears at the very top of the page. Could it have something to do with the masterpage? I've tried registering the user control in the master page, but I don't know how to reference it in the content page.
In my Default.aspx page I register my usercontrol at the top:
<%@ Language="VB" MasterPageFile="~/Master-Pages/Landing1.master" AutoEventWireup="false"
Title="Home" CodeFile="Default.aspx.vb" Inherits="_Default" %>
<%@ Register Src="/Controls/News.ascx" TagName="HomepageNews" TagPrefix="uc" %>
Then in my page I try include the control:
<asp:Content ID="NewsArea" ContentPlaceHolderID="ContentBottomCol" Runat="Server">
<%@ Register Src="/Controls/News.ascx" TagName="HomepageNews" TagPrefix="uc" %>
</asp:Content>
I've got a view with 2 forms on it - one to login and the other to register. My problem is that the client-side validation from MicrosoftMvcValidation is firing regardless of which form I submit - because my forms are rendering the inputs with the same id e.g.
<input id="User_Email"
name="User.Email" type="text"
value="" />
How can I change the generated forms to create different id's for the inputs in such a way that the validation works?
I'm using a strongly-typed view with a model with this property:
Model property:
[Required(ErrorMessage = "Please enter an email address")]
public string Email { get; set; }
First form:
<% using (Html.BeginForm("LogOn", "Account")) { %>
<%= Html.ValidationMessageFor(m => m.User.Email) %>
<%= Html.TextBoxFor(m => m.User.Email) %><% } %>
Second form:
<% using (Html.BeginForm("Register", "Account")) { %>
<%= Html.ValidationMessageFor(m => m.User.Email) %>
<%= Html.TextBoxFor(m => m.User.Email) %><% } %>
My second form produces id's identical to the first form which is causing the problem.
Is it possible to specify the difference in the Html helper on the view or do I need to provide 2 seperate models somehow? I'm a bit in the dark.

I have a weird thing happening. I have two identical databases installed on one virtual machine but under two different instances of SQLServer. For some reason, periodically when saving from one it will save to the other instead. Using debug, I have verified that the connection string is correct and when the item saves, it still saves to the wrong database.I use session variable, and am of the belief that it might have something to do with it...and t hat when I go from one to the other it is still getting the connection string form the other for some reason.To make sure that it isn't a problem, I make sure that I completely close out one database before opening the other in a new IE window.I assume that when I completely close out an internet explorer window that it abandons all session states. Is that true?
View 7 RepliesI have an update panel in a user control and I am adding multiple instances of it for example 5.

How can I prevent it only for once?
I have a piece of code that is just HTML. It was previously created as a user control. Within the application i'm working with there are two seperate websites that are interlinked to make one website. There is a documents section where users do not need to login and a data section where users need to login. The design was implemented long before I was hired. My problem is I want to use the code from the documents website with the data website but I can't seem to register the control. I only one this piece of code in one place so when it is updated it doesn't have to be in multiple places. I tried setting "src=http://website/doc/doc.ascx" but this errors out saying
<%@ Register Src="http://website/doc/doc.ascx" TagName="docs" TagPrefix="temp" %>
Parser Error Message: The file '/documents/http://website/doc/doc.ascx' does not exist.
It adds the directory as part of the src. How can I have it point to this location http://website/doc/doc.ascx ?
Within an ASP.NET user control I have the line:
<div>Web: <a href="<%# Eval("Web") %>"><%# Eval("Web") %></a></div>
I'd like to change it so this HTML is only rendered if Web has a value.
I've tried wrapping String.IsNullOrEmpty(Eval("Web") as string) in server side script but Eval can only be used inside a "binding" tag.
What is the best way to do this?
I have two usercontrols usercontrol1 and usercontrol2.
Now I have a hyperlink in usercontrol1 on the click event of which I need to display i.e show usercontrol2(otherwise it is hidden).
So I add Reference to usercontrol2 as in code give below:
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="Rehabilitation.ascx.cs" Inherits="SlumManagement.Web.UC.Rehabilitation" %>
<%@ Reference VirtualPath="RRules.ascx" %>
Now RRules.ascx is usercontrol2.
Now the problem is that after adding reference I only get to access on the server side not Client side.
Once I get a reference to it on the client side I want to do something like this:
function displayctrl()
{
var ctrl = document.getElementById('usercontrol2');
ctrl.style.display = "block";
}
How can I be able to do this?

I have a couple of buttons controls in my gridview pagetemplate. when i click in next page button it is calling wrong events calling my dropdownlist_selectedIndexChange event?
Situation: I have a drop down list which I need to pass on to a webservice on button click. I am using Sys.Net.WebServiceProxy.Invoke to make webservice call.
Everything is happening inside a usercontrol which loads on runtime using dynamicpopulate extender.
I get following error:
Sys.InvalidOperationException: Cannot serialize object with cyclic reference within child properties.
Situation: Usercontrol also has a listview which is bound to dataset. However on calling listview.DataBind() in side the webservice method.
I get following error:
The ListView control 'ProductsListView' does not have a naming container. Ensure that the control is added to the page before calling DataBind.
There is no problem when call to service method is parameter less and listitem is not bound.
I don't think I understand fully how ASP.NET does inheritance of controls.I have a user control, ucBase, which has an asp.net label in the ascx file. Code behind references the label and it works fine during run time if the control is not a parent for another user parent.
If I have another user control, ucChild, inheriting from ucBase, the label in ucBase's code is always null. ucChild has no controls in its ascx fileThe server controls (like the label) needs to be declared in the ascx file and not created programmatically.What needs to be done for ucBase to see its own controls when it's a parent user control?
I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)
<asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" />
[code]...
There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)
<script type="text/javascript">
function ValidateDateFields_Client(source, args) [code]...
There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.
<script type="text/javascript">

var ctl00_MCPH1_QueryTextValidator = document.all ? document.all["ctl00_MCPH1_QueryTextValidator"] : document.getElementById("ctl00_MCPH1_QueryTextValidator");

Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.

View 4 RepliesI think I summed up the question in the title. Here is some further elaboration...I have a web user control that is used in multiple places, sometimes more than once on a given page.The web user control has a specific set of JavaScript functions (mostly jQuery code) that are containted within *.js files and automatically inserted into page headers.However, when I want to use the control more than once on a page, the *.js files are included 'n' number of times and, rightly so, the browser gets confused as to which control it's meant to be executing which function on.What do I need to do in order to resolve this problem? I've been staring at this all day and I'm at a loss.
