My question is dealing with the DataList control. I am trying to add a click event to the rows of the "table" in the OnItemDataBound event.
The problem I'm having is I can't get a reference (through a row id attribute) to the "row" being generated by the DataList control (and more specifically the item template). Is there a way to add id attributes to the rows being generated by the item template?
I have a hyper link control and I set the NavigateURL and the ImageURL property at runtime. I also need to set the class of the image tag that it generates but I cannot figure out how I can do that. The solution mentioned here [URL] does not work because the image url is hard coded.

There is an existing web service WSDL that I have reverse engineered with wsdl.exe to create a C# proxy class.
Using Visual Studio 2008 I created a default web service template.
How do I reference the generated proxy class so that it will work in the web service?
For example -> calling http://localhost/webservice/service.asmx?WSDL will return the details from the proxy class.
I'm new to this forum, Ok here is the problem. I tried to implement the user profile pattern that provided by ASP.Net 2.0, first I added this couple of tags to the web.config
<system.web>
<anonymousIdentification
enabled="true"/>
<profile>
<properties>
<add
name="Name"
allowAnonymous="true"/>
<add
name="Age"
allowAnonymous="true"
type="System.Int16"/>
<group
name="User">
<add
name="Category"
allowAnonymous="true"/>
<add
name="MemberSince"
allowAnonymous="true"
type="System.DateTime"/>
<group>
<properties>
<profile>
Then I buit the project and moved to the page code behind, the surpise is that I didn't have the Profile object in the intellisense.
Is there a method like IsValid(); in Entity Framework Generated classes?
Would I have to create a method like the above?

I would like the method to return a boolean.
i'm worried about doing this since my changes will be overwritten when the dbml file is auto generated again (as they often are).
i'm thinking of doing a partial class and writing out the same properties to annotate them, but worried that it will complain about duplicates, and the reason i can't even experiment brings me to the second part of my questions...
... that, the expandable arrow on my dbml file listing is missing, right clicking and selecting "View Code" just displays an empty partial class as below...
Partial Class FPDataContext

I'm trying to implement my own Membership provider. I don't want to dig in very details but only high level logic. And first I don't understand is how can I use the class User generated from database in my CustomMembershipProvider project?
I thought I shouldn't generate class User in my project which uses my custom provider because it just don't need any users. It's only for login/logout functionality which implements Membership provider, not project that uses it.
Then I thought that I should pass Connection String to my Membership provider in order to make UserEntity somehow and use it inside Membership provider. I have two separate project for Membership provider and for any else project using Membership.
How could I create and use ADO.NET Entity in CustomMembershipProvider project for User table which located in database in other project?
When you add a Web Reference in an ASP.NET project in Visual Studio the web application's root namespace is always added.So, if I add a web reference called MyWebService and the default namespace of the application is MyApplication the namespace of the generated proxy class will be: MyApplication.MyWebService.
However, I want to be able to specify which namespace to use for the generated class (to skip the default namespace and have the namespace be called simply MyWebService).Is using wsdl.exe through the command line the only way of accomplishing this? I don't want to manually edit the generated class (since it can get re-generated).
when I compile some .py codefiles with no class definitions into dlls , the compiled dll is created with a "DRLCachedCode" class inside. Why is that?

What I'm trying to do is take an instance of a control, and figure out what the markup would look like based on the property values set in the code behind. We've built a web-based web form designer. At the end of the design process we save the markup. For simple controls with supported types, generating the markup was easy. For complex controls with nested properties or unsupported types, we're faced with creating a custom markup generator for each custom control. I was hoping to find info out there that would jump start this development effort.
In simple terms, I have this:
Dim Ctl as Control = CType(Asm.CreateInstance("MyNameSpace.MyControl"), Control)
Ctl.Name = "Name of my control"
And I want to end up with this:
<cc1:MyControl ID="MyControl1" runat="server" Name="Name of my control" />
I have this Control directive in a usercontrol (i've changed the namespace and class name):
<%@ Control Language="C#" AutoEventWireup="true" Inherits="Namespace.Path.To.ClassName" %>
<asp:TextBox runat="server" ID="txtComment" TextMode="MultiLine" ValidationGroup="comment" />
ClassName is a class that lives in a class library and this is the class:
namespace Namespace.Path.To
{
public class ClassName : System.Web.UI.UserControl
{
protected System.Web.UI.WebControls.TextBox txtComment;
protected void Page_Load(object sender, EventArgs e)
{
HttpContext.Current.Response.Write(txtComment == null);
HttpContext.Current.Response.End();
}
I have build a UserControl with separate code behind file.In that code behind file i have defined some public properties in the Partial class of user control that was automatically generated.Those properties will initialize some properties of controls that are used in the control.Now, in .aspx page i used this User Control and initialized the public properties through code behind of aspx page for dynamic contents.

View 2 RepliesI'm looking for ways to reduce the size of my page . I have a page that just renders a gridview - no images - and it is over 400k!
Looking at the html that is generated I see the names of the controls in the gridview are very very long. For example: ctl00_ContentPlaceHolder1_releaseGV_ctl149_lblBuy
My gridview is about 200 rows by 13 columns = ~ 2600 spans with very long names rendered. The above example is 49 characters X 2600 controls = 127,400 characters just in control ID's!
The actual data on my page ins't anywhere near a tenth of that!
I am already storing viewstate on the server.
YES, I will put a pager on this page to bring down the number of rows. Also, I've seen sever other posts related to page size with some excellent content. I will follow up on them - however I have not seen this specific question answered.
Here is a sample of my page. As you can see there is not much data and a lot of html!
[Code]....
I've recently added a Master Page to my site,but realized that it's caused some problems in my existing JavaScript setup.I am able to use the following code in most places without any issue to get the ClientID: '<%=myControl.ClientID%>'
The problem I have encountere is that I have several pages that add controls dynamically,and then execute events based on an ID that's passed in,where I can't use this line,because I won't know the ID of the control I'm trying to access until the Javascript executes.Here's a simplified version of the problem:
When the page runs,it creates n textboxes dynamically,and appends a relevant ID from the database to the end of the ID.Let's say the page has added 3 textboxes with the following IDs:
myTextBox1
myTextBox7
myTextBox115
Later,a javascript event fires,and I need to be able to access the control through JavaScript like this:
myJavaScriptFunction (controlID)
{
myvar = document.getElementById('myTextBox' + controlID);
}
I am using a third party control for my web page. I do not have the source code to the DLL. I need to make a very small change the html that the control generates. Is there a way to capture the html generated by the control, and then render the control with that small change.I can override the render method of the parent control, is there a way in that method to find out the html that the control generates in there and render it with the small change?
View 4 RepliesI have a PlaceHolder control inside of a ListView that I am using to render controls from my code behind. The code below adds the controls:
TextBox tb = new TextBox();
tb.Text = quest.Value;
tb.ID = quest.ShortName.Replace(" ", "");
((PlaceHolder)e.Item.FindControl("ph_QuestionInput")).Controls.Add(tb);
I am using the following code to retrieve the values that have been entered into the TextBox:
foreach (ListViewDataItem di in lv_Questions.Items)
{
int QuestionId = Convert.ToInt32(((HiddenField)di.FindControl("hf_QuestionId")).Value);
Question quest = dc.Questions.Single(q => q.QuestionId == QuestionId);
TextBox tb = ((TextBox)di.FindControl(quest.ShortName.Replace(" ","")));
//tb is always null!
}
But it never finds the control. I've looked at the source code for the page and the control i want has the id:
ctl00_cphContentMiddle_lv_Questions_ctrl0_Numberofacres
For some reason when I look at the controls in the ListViewDataItem it has the ClientID:
ctl00_cphContentMiddle_lv_Questions_ctrl0_ctl00
Why would it be changing Numberofacres to ctl00? Is there any way to work around this?
UPDATE:
Just to clarify, I am databinding my ListView in the Page_Init event. I then create the controls in the ItemBound event for my ListView. But based on what @Womp and MSDN are saying the controls won't actually be created until after the Load event (which is after the Page_Init event) and therefore are not in ViewState? Does this sound correct?
If so am I just SOL when it comes to retrieving the values in my dynamic controls from my OnClick event?
UPDATE 2:
So i changed the code i had in my Page_Init event from:
protected void Page_Init(object sender, EventArgs e)
{
if (!this.IsPostBack)
{
//databind lv_Questions
}
}
to:
protected void Page_Init(object sender, EventArgs e)
{
//databind lv_Questions
}
And it fixed my problem. Still a little confused as to why I want to databind regardless of whether it's a postback or not but the issue is resolved.

I am creating a Table Control programmatically and I want after user clicks a button to get the values.
The table has three columns, {Title(DropDownList), FName(TextBox), LName(TextBox)} and two rows.
I am getting the values for FName, LName without problem, but I am getting wrong value for Title, which is a DropDownList. It gives me for both Titles, the selected value of the second column.
More Clear
For the 1st row --> Mr, Foo, Bar
for 2nd row- -> Mrs, Foo, Bar
after user clicks the button I am getting
For 1st row --> Mrs, Foo, Bar
For 2nd row- -> Mrs, Foo1, Bar.
This is the method of table creation
