I've noticed that on aspx page IntelliSense doesn't display the Style property of a web control, even thought the control does have a Style property. Does that mean we shouldn't declaratively set the Style property:
<asp:TextBox ID="UserName" Style="color:Green; padding:0px; margin:0px;" runat="server"></asp:TextBox>
I've been binding dropdownlists within detailsview controls like so for years
SelectedValue='<% Bind("Field1")%>'
Now in VS 2008 is kicks out the error in the subject line. So what gives? And how do we bind dropdownlists then?

I want to code some colors in the style property of some controls. For instance, I want to use some like DarkGoldenrod, which is shown as
ARGB=(255, 184, 134, 11)
How do I convert this to something that I can use in a style property (e.g., style="color: #CCCCCC)? I know how to convert the first three numbers (255, 184, 134) into a six digit hex value, but what do I do with the fourth number (11)?

I tried to put a ListView onto a webform but got an error right after that:
Error Creating Control - ListView1
The 'CssClass' property cannot be set declaratively.
BTW, does ListView support horizontal/vertical scroll bar? As I might have about 50 records in maximum, so need to have horizontal and vertical scroll bars. But do not need paging.
How can i remove an error of gridview which indicate that " the selected property can't be set declaratively.
View 2 RepliesI need to set a style property of an element to the value returned from a code-behind property. I have done this in the past, but it now seems everything I try fails. I get an error telling me that the literal is not formed correctly.These are some of the arrangements I have tried:

Normally, unknown attributes of a webcontrol are passed through to to the rendered element in the browser. So the following works.
<asp:label runat="server" Text="Label Text" helpId="101" />
However, if you use a namespaced attribute like the following
<asp:label runat="server" Text="Label Text" myNs:helpId="101" /></div>
The attribute is not rendered to the client, even when the custom namespace is declared in the html element like: <html xmlns= [URL] Does anyone know of a way to get this to render to the client, without having to use a custom control. A module or other globally "pluggable" solution would be acceptable.
I've been working on this project for a few days now, and have been unable to resolve the issue of getting intellisense support for my custom-defined inner properties for a user control (ascx, mind you). I have seen the solution to this (using server controls, .cs mind you) many times. Spelled out in this article very well. Everything works for me while using ascx controls except intellisense. Here's the outline of my code:
[PersistChildren(true)]
[ParseChildren(typeof(BreadCrumbItem))]
[ControlBuilder(typeof(BreadCrumbItem))]
public partial class styledcontrols_buttons_BreadCrumb : System.Web.UI.UserControl
{
...
[PersistenceMode(PersistenceMode.InnerDefaultProperty)]
public List<BreadCrumbItem> BreadCrumbItems
{
get { return _breadCrumbItems; }
set { _breadCrumbItems = value; }
}
...
protected override void AddParsedSubObject(object obj)
{
base.AddParsedSubObject(obj);
if (obj is BreadCrumbItem)
BreadCrumbItems.Add(obj as BreadCrumbItem);
}
...
public class BreadCrumbItem : ControlBuilder
{
public string Text { get; set; }
public string NavigateURL { get; set; }
public override Type GetChildControlType(string tagName, System.Collections.IDictionary attribs)
{
if (String.Compare(tagName, "BreadCrumbItem", true) == 0)
{
return typeof(BreadCrumbItem);
}
return null;
}
}
}
Here's my mark up (which works fine, just no intellisense on the child object declarations):
<%@ Register src="../styledcontrols/buttons/BreadCrumb.ascx" tagname="BreadCrumb" tagprefix="uc1" %>
...
<uc1:BreadCrumb ID="BreadCrumb1" runat="server" BreadCrumbTitleText="Current Page">
<BreadCrumbItem Text="Home Page" NavigateURL="~/test/breadcrumbtest.aspx?iwentsomewhere=1" />
<BreadCrumbItem Text="Secondary Page" NavigateURL="~/test/breadcrumbtest.aspx?iwentsomewhere=1" />
</uc1:BreadCrumb>
I think the issue lies with how the intellisense engine traverses supporting classes. All the working examples I see of this are not ascx, but Web Server Controls (cs, in a compiled assembly).

i have a user web control wich has the website menu. this menu is viewed through out the entire web site.
i would like to mark the selected link, on the menu with in the web user control,in some way (red background or w/e) the thing is, i cannot manage this from client side since there is a page_load on every click on the menu (witch brings up a different page). the only thing i can think of is saving the click to the session and then retrieve what was clicked and change the style accordingly via c# in the code behind.

View 4 RepliesI'm using the new Routing feature in ASP.NET 4 (Web forms, not MVC). Now I have an asp:ListView which is bound to a datasource. One of the properties is a ClientID which I want to use to link from the ListView items to another page. In global.asax I have defined a route:
System.Web.Routing.RouteTable.Routes.MapPageRoute("ClientRoute",
"MyClientPage/{ClientID}", "~/Client.aspx");
so that for instance http://server/MyClientPage/2 is a valid URL if ClientID=2 exists.In the ListView items I have an asp:HyperLink so that I can create the link:
<asp:HyperLink ID="HyperLinkClient" runat="server"
NavigateUrl='<%# "~/MyClientPage/"+Eval("ClientID") %>' >

My date picker has no style as in it doesnt seem to be recognising the style sheet

and my html

My <style> for thumbnails currently looks like this:
<style type="text/css">
img.TN {
width: 100%;
margin-bottom: 5.294%;
cursor: pointer; }
</style>
This is annoying, because I have to apply this style to every single thumbnail image individually, when there could be any number of them on the screen at any given time. All of the thumbnails are inside a single <div> that groups them together, and I'd like to apply a single style to the <div> that will push the attributes I need down to all of the the <img> elements nested inside, regardless how many thumbnails there are.
I'm using ASP.NET 2.0, and CSS 2.0

I'm working with a simple UserControl someone at my company created. It's basically just a DropDownList with a RequiredFieldValidator and some added properties (such as "Required", which controls the CSS styling of the DropDownList and whether the RequiredFieldValidator is Enabled or not).
Here is an example of the UserControl usage where a SqlDataSource is used to populate the ListItemCollection. I'm trying to specify an intial ListItem below (and would like the ability to add multilple ListItems if necessary) but can't seem to get this to work...
[Code]....
My code-behind looks as follows:
[Code]....
I've found several posts related to this but cannot seem to get the declarative ListItem to be added to the DropDownList.
I understand that using a WebControl is another option, but I'd like to learn how to get this method to work if possible.
my web application i use FindControl to retrieve a Control By Name (it returns an System.Web.UI object). The control can be of various type and I don't want to treat them differently: I'd like to set the Text property to a defined string. I hope there's a class that I may use to cast the control and set the Text property.
View 8 RepliesAjax AsyncFileUploader is appreaing very bad in my ASP.Net(C#) web app.
Another very annoying thig is that; when its style is set to modren it does not show that grey image with the text "Select File" in any of the browser except IE 7.
While with "Tradition Style" the height of this control looks so squeezed in both IE 7 & IE 8 , And Is there any way so that we can change the style of that Browser button like the other buttons on out site and can we apply textbox skin on the uploader to it can shape like a textbox?
I am converting across an old popup system from an older app into a newer one and want to take advantage of the ajax control toolkit to do all of the popups.
Unfortunately the business will require me to make the popups look like the old version (essentially just another page opened in a smaller window and showing the title bar). The problem I can see with using the ajax toolkit is that there is no "title bar" that gets included with it as its not really a new window.
Server control code:
<asp:RequiredFieldValidator ID="RequiredFieldValidatorOnlineID" runat="server" ControlToValidate="TextBoxOnlineID" ErrorMessage="Online ID is required.<br />" ToolTip="User Name is required." SetFocusOnError="True" Display="Dynamic" CssClass="validationerror"></asp:RequiredFieldValidator>
Rendered Server control code:
<span id="ctl00_ContentPlaceHolderSYLMainMaster_RequiredFieldValidatorOnlineID" title="User Name is required." style="display:none;">Online ID is required.<br />
I have tried the following to remove the style attribute with no luck:
RequiredFieldValidatorOnlineID.Attributes.Remove("style")
and
RequiredFieldValidatorOnlineID.Attributes.Clear();
I don't need and want the style attribute, how can I prevent it from being written into my code? It messes up the alignment of the error message with my textbox.
My validation controls don't line up with my textboxes because I can remove the inline styles, how can I make style=display:none disappear?
<span id="ctl00_ContentPlaceHolderSYLMainMaster_RequiredFieldValidatorOnlineID"
title="User Name is required." class="validationerror"
style="display:none;">Online ID is required.<br />

I am using asp.net menu control with sitemap. I placed this control in master page. I want to apply style sheet for that menu control. Can any one tell how to do that.
[code]
What I want to do is to split-up the globalnavigation bar on the sharepoint 2010 so I can control what menu-items should be floated to the left or right of the bar.
Is there a way to do this without a complete customized version of it, so I only have to edit the current one. Or do I actually have to make a complete new one?
What I have tried so far is just copying all of the UL > LI's there's used to display the menu-items like this:
<div class="s4-tn">
<div class="menu horizontal menu-horizontal">
<ul class="static">
<li class="static dynamic-children">
<a href="#" CssClass="static dynamic-children menu-item">
<span class="additional-background">
<span class="menu-item-text">Custom Dropdown</span>
</span>
</a>
<ul class="dynamic">
<li class="dynamic">
<a href="#" class="dynamic menu-item">
<span class="additional-background">
<span class="menu-item-text">Test subsite</span>
</span>
</a>
</li>
</ul>
</li>
</ul>
</div>
</div>
But it doesn't seem to trigger the dropdown functionality. Might just be a naive attempt.
Any links to guides or tutorials about this subject would be a great.
