AJAX :: User Controls And Control Extenders / Rendering A SPAN As An Element To Surround The Control?
Aug 24, 2010Two separate questions, but sufficiently intertwined that I'm going to try the two together....
Firstly - User Controls and Behaviours
I have a User Control which contains a few visual controls. I am attaching some behaviours by using GetScriptDescriptors and am passing some JavaScript to the browser using GetScriptReferences. That is all rock solid and working well. However, when developing, I did discover that I couldn't attach the ehaviours to the User Control itself - not surprising as rendering a User Control does not create a DOM element which represents the actual control. So, I have attached my behaviours to a "random" TextBox within the User Control.
So - first question, is there a better way to do that? For example, should I always be rendering a SPAN as an element to surround the control? Not sure what that would do to the robustness of the rendering. What is the right way to attach a behaviour to a User Control.
Secondly - Accessing those same Behaviours later
Assume I have placed a User Control on the page. That User Control exposes a Property (actually a Javascript Function of course) which does "something" to the control - for the sake of example we'll say that the function is set_Border(colour). I then have a behaviour on the same page (actually an Extender on a different control) which needs to call the function. I have a reference to the User Control in my script, so I have tried TheControlReference.set_Border('red') and find that my control doesn't support the set_Border method.
I guess this is probably because the behaviours are not attached to the User Control itself, but to a GUI element within it. Hence, I suspect that the answer to the second question lies within the answer to the first.

C# - Wrap ASP Control With Double Quotes
Jun 23, 2010I'm working in a Repeater over blog posts and I'm displaying a ShareThis JavaScript piece at the bottom. The Title and URL of the post are being sent to JS. In one test case, the title of a post has a single quote, e.g. Mark's test post Since I need to preserve that single quote when being sent to ShareThis, I need to wrap that JavaScript string in double quotes, however the string is being bound via a Literal and I cannot wrap the literal in double quotes: This is want I want but DOES NOT WORK:
SHARETHIS.addEntry({ title: "<asp:Literal ID="ltlTitle" runat="server" />", etc..
I can only wrap the literal with single quotes like so:
SHARETHIS.addEntry({ title: '<asp:Literal ID="ltlTitle" runat="server" />', etc..
But that will result in bad front-end code:
SHARETHIS.addEntry({ title: 'Mark's test post', etc..
How can I encode this correctly or somehow wrap the control in double quotes? I'm aware of HttpUtility.HtmlEncode and Server.HtmlEncode

Jun 17, 2010I have a grid bounded to a datatable. Suppose the data for a column is like this "New Task 12:45AM-01:00AM Testing" . I need it displayed in a single row of the column.

Add Control Programmatically In Page_load
Dec 19, 2010I am trying to add controls on the page from the backend in the page_load stage. Here is my code:
foreach (FileInfo fi in dirInfo.GetFiles())
{
HyperLink hl = new HyperLink();
hl.ID = "Hyperlink" + i++;
hl.Text = fi.Name;
hl.NavigateUrl = "../downloading.aspx?file=" + fi.Name + "&user=" + userIdpar;
Page.Controls.Add(hl);
Page.Controls.Add(new LiteralControl("<br/>"));
}
The error which I am getting is on 'Page.Controls.Add(hl);' and here is the explanation: The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases. What can I do so I can fix this issue.
How To Wrap Dll To Web Services
Jan 25, 2011I am facing the situation in which i have to expose a dll (managed) through web services. Basically make everything from dll accessible to other applications through web services. The dll is a third party and i cannot give any other info on it , but my problem would not depend on this details.
I am looking for the latest best practices (latest tech) approach on how to start this. One thing i have been documented over was Web Service Software Factory, but i do not know how good would this approach be for my situation, and i would welcome some ideas based on experience ofc. The top things i liked and need in my project about the WS Factory were : SOAP faults handling , Entity Translator , Versioning (covering both forward and backward compatibility).

Sep 27, 2010I have a blank/unbound GridView control on my form and I am binding it in the code behind like this:

Programmatically Cancel Control Initialisation?
Jan 11, 2010Suppose I have a user control MyControl.ascx, and I put it in the Default.aspx like this:

Now in the code-behind of Default.aspx I do this:
[code]....
The problem is that even I do not render MyControl, it is still being initialised and goes through the entire ASCX life cycle (OnLoad, etc). Is there a way to prevent the control from being initialised at all?

Web Forms :: Can Add Validator Control Programmatically
Feb 3, 2011I am adding validator controls to a page on runtime. When I do this it seems to work except for one thing: the page doesn't get validated (the Validate() method is not invoked) - neither on the client nor on the server. However when I can Validate() myself, the validators do their work and generate the required errors. So it looks like the simple fact of adding a validator programmatically causes the page validation to not take place. My page does have validators in the aspx file - they work fine when I don't add any programatically, but as soon as I do add one programatically, the Validate() method is not invoked.
The way I add the validators is by creating an instance, giving values to all relevant properties, and then adding to the page control collection. I tried this in the PageLoad, and prior page-cycle events. The same result occured. I also tried with or without having a ValidationGroup, and with or without having a ValidationSummary control on the page. The same result occured.
Programmatically Adding A User Control In C#?
Jan 12, 2010I have a user control that needs to load a child control when a button is clicked. The trouble is that it has to request the control from another class.
So in the button click event, I call the function to get me my control, and add it to the page, like this:
UserControl ctrl = ExampleDataProvider.GetControl(some params...);
myDetailPane.Controls.Add(ctrl);
The GetControl method looks like:
public static UserControl GetControl(some params...)
{
ExampleDetailPane ctrl = new ExampleDetailPane();
ctrl.Value = "12";
ctrl.Comment = string.Empty;
return ctrl;
}
This isn't working due to the page's lifecycle - the Page_Load of the child control gets fired and its controls are null.

View 4 RepliesC# - How To Programmatically Set Property Of Control In Aspx File
May 27, 2010This may be a very dumb question but I can't seem to get it working. I use at many places the following syntax for dynamically binding a property of a control in aspx file to the resource entry, e.g.
<SomeFunnyControl Text="<%$ Resources : ResClass, ResEntry %>" />
I want to do a similar thing with a class containing some constants, something like
<SomeFunnyControl Text="<%= MyConstantsClass.MyStringConstant %>" />
But this doesn't seem to work, it simply sets the text to the exact expression without evaluating it. I am using ASP.NET 3.5 btw.
I have tried the databinding approach but I get an HttpParseException saying Databinding expressions are only supported on objects that have a DataBinding event.

Web Forms :: Programmatically Populate A Menu Control?
Apr 1, 2010I've an asp menu on my site. I need to dynamically populate this from my database depending on a choice made by the user.
Basically, when entering the site the User chooses a product category and this selection determines the options in my menu. I'm totally lost as to how to populate my menu each time the user changes their category - I've only ever hardcoded in the values to a this menu type so I've no idea how to programmatically populate it.
From what I can gather, it seems that its best to populate the menu via XML - if this is so could someone post a sample of what this XML structure (or let me know ehere I can view this)
C# - Apply Skin To A Control Created Programmatically?
May 13, 2010Say I am creating a Textbox in the codebehind of a page like this:
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
TextBox test = new TextBox();
test.SkinkId = "MySkin";
placeHolder.Controls.Add(test);
}
and in my skin file I have this:
<asp:TextBox
runat="server"
SkinId = "MySkin"
Width="400"
/>
Why is the skin not beeing applied to the control. If i declare the control in my aspx page it works ok, but if I try to do it programatically it does not work...
