View 2 RepliesI have some simple code in an aspx page
<object width="550" height="400">
<param name="movie" value='XXXX' />
<embed src='XXXX' width="350" height="370"></embed>
</object>
I want to be able to dynamically set the value of XXXX.
I have been experiencing some very strange behavior using html buttons with the onserverclick attribute. What I am trying to do is use jQuery to designate the default button on the page. By default button I mean the button that is "clicked" when a user hits enter. In testing, I would hit enter while in an input field and sometimes the intended "default" button was clicked and the server side method defined in the corresponding onserverclick attribute was hit. Other times a post back was made without hitting the server method. In order to isolate the issue I created a minimal test case and found some very interesting results.
Client side:
[Code] ....
Server side:
public partial class admin_spikes_ButtonSubmitTest : System.Web.UI.Page {
protected void Page_Load(object sender, EventArgs e) {
} protected void ServerMethod1(object sender, EventArgs e) {
_response.Text = "server method1 was hit";
} protected void ServerMethod2(object sender, EventArgs e) {
_response.Text = "server method2 was hit"; } }
What I found was that everything worked as expected with this code except when I removed one of the input elements. In Firefox 3.6 and IE 8 when only one input exists on the page, hitting enter does not trigger the onserverclick, it makes a post back without even being jQuery "clicked" or actually "clicked". You can test this by starting with two inputs and clicking "test2". This will output "server method2 was hit". Then just hit enter and the output will be "server method1 was hit. Now take away an input and run the same test. Click "test2" see the results, then hit enter and you will see that nothing will change because the "test1" method was never hit. Chrome worked as expected
I am creating a web user control for a simple poll. I am currently registering it on the page and then referencing it via tagprefix.
The form for the poll is in basic html (no server controls) and is in the front-end of the web control. How can I change the look of the user control depending on the settings passed into it? Is this possible without using server controls?

Can I change the html layout of a user control?
I recently designed my own user control.
My control consists of an ASP:Tree control and a plain HTML text input with copious Javascript, jQuery, and .net code to bring them to life together.
I have two issues.
1) I can only have one instance of this control on a page at a time. The text input is named txtUserControl, so putting a second instance on the page causes a name collision. I have the same issue with the ASP:Tree.
2) If I put my user control inside an ASP:UpdatePanel, it does not work at all. I get errors all over the page when I try to refresh it. Incidently, I have this same issue with a user control created by one of my co-workers.
I have some ideas for controls that I would like to be able to use again and again in my projects. I would like them to be rock-solid.
I have created a Web User Control (e.g, uc.ascx) which has a few HTML checkboxes in it (using Input Checkbox).
As uc.ascx is dynamically created in my webform page (e.g. page1.aspx), I discovered that the HTML checkboxes did not persist their "Checked" status. how I can make these HTML checkboxes persist?
i have found out a way to find controls on content pages by using
var txt = $('input[id$=TextBox1]'). But how to access html elements like "<p>" tag and others in jquery when the html elements are in content page only.
How can I control on HTML elements by using C# code in asp.net pages.
For example:
I want to change the content of span tag or td tag when load page... that's mean write code c# in Default.aspx.cs for example to change Span content
I just found out that there is sort of a neat control called the "Menu-control"..but the thing is that I actually whould need my menuitems to contain more then just a plain text link..

This since I whould need to style my menuitem abit different..is this possible..and how?

View 2 RepliesI have created an asp.net application which contains a user control. Within the application this control works fine. I have then moved the control into a separate "control library" project. When I try to load the control from the control library I find that the asp elements defined in the ascx for the control are not instantiated - i.e. I get a null reference exception in the Page_Load event handler. The only changes that I have made to the original application are to reference my control library and to change the <%@ Register statement in the loading page to reference the control library dll:
[Code]....
Do I need to do something else to get the user control to initialize itself correctly?
I have a string like these:
String data = @"<table id="_grp:CONSUMER_APPLICATION" cellpadding="0" width="660">

<table id="_headerTable" class="Dark" cellspacing="0" cellpadding="0" width="660" border="0">

I just recently started messing around with .NET (converted over from PHP) and I'm really enjoying it. I've created a test site for some friends at work and it works great. But I've been slowly converting the pieces of the site into user controls. I've moved some DataGrid elements to user controls for their specific purposes, and now I'm working on the main page (I'll attempt to copy the code below).
So pretty much this control displays:
1. An error panel
2. A podium panel (gold, silver, bronze) medals
3. A cake podium (the person who gets last place)
Before I moved this to a user control it worked perfectly. The Image files were updated from the SQL results. Believe me, I know it's not optimized so lets skip over that part. But when I view the dev site, the images are showing up as blank or broken. Nothing I do to change one of the ASP elements in the user control are being updated. I have a Response.Write sitting there just to ensure that the events are being caught and handled correctly.

View 1 RepliesI'm creating a control based on ScriptControl, and I'm overriding the Render method like this:
protected override void Render(HtmlTextWriter writer)
{
RenderBeginTag(writer);
writer.RenderBeginTag(HtmlTextWriterTag.Div);
writer.Write("This is a test.");
writer.RenderEndTag();
RenderEndTag(writer);
}
My question is, what if I want to assign the div an ID attribute and have it be unique on the page, even if there are mulitple instances of my control?
I've seen other people's code that does this:
writer.AddAttribute(HtmlTextWriterAttribute.Id, this.ClientID + "_divTest");
That will prevent naming conflicts between instances of my control, but what if I've already created a div elsewhere on the page that coincidentally has the same ID?
I've also heard about implementing INamingContainer. Would that apply here? How could I use it?
UPDATE:
I've worked around this by overriding CreateChildControls and adding actual controls, as opposed to rendering HTML directly. In that case INamingContainer does its job. However, I'm still curious if there's a way to solve my original problem (unique IDs for directly rendered elements).
I've got a custom ASP.Net web user control I've built; done this enough times before but this one is misbehaving and I can't spot why.
Where the calling page includes the user control directly in its markup, all is well and the control behaves as expected.
However if the page adds this particular control dynamically (to a placeholder in the master page, which is what's calling this whole thing) the elements within it stay firmly NULL - nothing from the user control gets written to the client at all, including static content within the user control.
I am facing challenge of changing action attribute of html form tag. As my application is on shared hosting (medium trust) environment of godaddy server, I cannot use reflection to get control adapter of html tag page. So, I cannot use the following code in my Url Rewriting module.

Is there any otherway to implement the same functionality without reflection?
I have a set of links that exist in the master page. I have a css class i would like to assign to a particular one of them depending on if that is the page you are at during page load. ex: Home will have the current_page_item class if you are at the index page
This is what I have:
Code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
DirectCast(Me.Master.FindControl("ctl00_homeLi"), HtmlGenericControl).Attributes.Add("class", "'current_page_item'")
End Sub
I've created my user control. In the page I've written my markup as follows:
<uc1:myUserControl id="myUserControl1" Enabled="true" runat="server" />
I cannot get the value Enabled="true" in the code behind during page load.
how can i set style attribute in code behind c#?
View 2 RepliesIf certain attributes on built-in ASP.NET controls aren't specified, then an exception will be thrown.
How do I do this on my custom user/server control?
[Code]....
I am having a problem setting the SystemObjectRecordID attribute of my custom control inside a repeater. Currently, the value winds up as zero in the database. Things I have checked:
1) The datatype of the DB column (bigint) and the datatype of AlertId (long) and the datatype of the getter/setter SystemObjectRecordID variable (long) match.
2) If I set '<%# ((Alert)Container.DataItem).AlertId %>' to the Text attribute of a label I get the expected results. So, it has something to do with my custom control and specifically how data isbound to the SystemObjectRecordID attribute.
Now, going to the server, below is what I have for databinding (The page is Default.aspx.cs and the namespace is Company.ProjectWeb.Profiles):

Currently I am trying to pass the value received from a literal (because I know that the values are received as expected here) to the SystemObjectRecordId object. Still isn't working. I am still getting a value of zero when I set a breakpoint and look at the value of SystemObjectRecordId in the codebehind of my control:
