Custom Server Controls :: Custom Control's Constructor / User To Set That variable In The Properties Window After They Drag The Control Onto A Form?
Mar 4, 2010I have a custom control which inherit from the Table class and in the constructor, it takes a an integer as an argument. There is no empty constructor.
Is there a way for the user to set that variable in the properties window after they drag the control onto a form.
I know some .NET controls, you can set the source for the parameter to different things like another control's property, QueryString using just the properties window.
Right now, I have to create the control dynamically. I read the query string and then created the object.

The above code compiles without any error. Also I can drag and drop this control from the Toolbox of my Project on my web form. However I am unable the change the value of my fromLabel control.It allows me to change the value in the properties window.But when I run the form it always shows me its default value which is "From". I want it to be flexible so that any one can change the value in the properties window.

Web Forms :: Dynamic User Control And Setting Properties?
Jan 25, 2011I have a user control (i.e. ascx) that comprises of two related list boxes (i.e. once you change the selected item in one list the contents of the other list update). I'm adding this user control dynamically to a page on the click event of a button (i.e. using LoadControl).I wish to set the list box datasource properties, as well as the default selected item of the parent list from my parent page so I created public properties in my user control to accomodate this. I also created an event in my user control that notifes the parent page when the selected item changes in one of the list boxes so I can update the contents of the other list box.
I understand that I have to recreate the user control on every postback in order for it to function correctly but I'm not sure exactly how I should be doing it. I've shown below what I have currently - whilst it works the problem is that on postback I'm always creating the user control with all its default properties and then updating the properties that need to change(?). For example, when the choice in theparent list box changes the datasource of the list box is set twice (once in AddControl and then again in OnParentChanged)? As the contents of the list boxes originate in a database it means I'm making unnecessary calls to the database (unless I do some something like store each unique set of data in the ViewState).
I'd be very grateful if someone could review how I've done things and illustrate how perhaps I should be doing things. I'm not sure if the way I've done this is considered the 'correct' way. For example there may be a better way of doing things would avoid setting the properties twice? I'm a bit unsure of the way I've set the datasource properties of the list boxes and bound them. I wished to set the datasource from the parent page because I might have a second user control on my page that may also use the same datasource and I could reuse it (as opposed to each control making its own call to the database) so I'd like to keep this feature if possible.It would be great if posting code in reply that you use my example as a guide so I know what you're referring to.Here's the code for my user control:

Forms Data Controls :: Setting Properties On Web User Control In Dynamic GridView
Jan 7, 2010I am in need of some assistance in regards to how to best set the values of properties for a Web User Control which is being included into a cell of a GridView with dynamically created columns. I have tried a few different approaches, but can't seem to get a satisfactory result. Also, to be completely honest, I am not really sure if I am using best practices for what I am trying to accomplish.
First off a little background:I have a GridView for which we will never know the exact number of columns at run time. The columns are predicated by user selection. I am creating the command text for the DataSet on the fly and then looping through the columns of the resulting DataTable in order to use custom TemplateFields. This works ok for just printing out the row values but not so much for when I need to insert the Web User Control into a cell.The Web User Control is in essence a collection of image links which are used as a "Quick Nav" tool. I need to pass the values of 2 fields from each DataRow to the control via properties (for example, CustID and ProductID). I am using custom TemplateField classes inheriting from ITemplate for displaying my fields and extending the DataBinding event like so: [Code]....
This won't work for my User Control as DataBinding is called after the control is loaded into the page and I need the properties to be set before the Page_Load event of the control is fired.Is there a GridView event I should be looking into instead such as RowCreated or RowDataBound? Or should I modify how I loop through the DataTable by doing rows first, then the resulting columns as I've seen done elsewhere?

Custom Control Properties Not Initializing Properly
Dec 14, 2010The First - LblTextBox:
A label and textbox that have a LabelText field that can be set to change the label text
The Second - LoginCtl:

I want to control the tag rendering of these controls for formatting so I am not overriding CreateChildControls() to get the job done.
My issue is that the controls are rendered but none of the OnInit() code in either controls takes hold (blank labels, css styles not applied, etc..).

Jquery - Creating A Custom Control In Javascript Properties And Methods?
Feb 23, 2011As a starting point for creating custom controls, I would like to make a control that simply displays a number. If we imagine the .ascx file contains nothing except for a literal control, and the code behind sets that value to 1.
I then want to be able to do myControl.increment();
This will run some javascript that increases the value of the literal control.
I could inject a javascript into the page, such as pseudocode:
page_load
{
scriptything.register("function increment(x) { $('#myLiteral').increment(); });
}
or something, but that wouldn't be myControl.increment, that would just be increment(). More than one control on the page would screw it up.
Missing Intelligence While Describing Custom Control Properties Declaratively
May 21, 2010I'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).
How To Expose Child Control Style Properties In A Custom Composite WebControl
Feb 23, 2010I am writing a custom composite WebControl and want to expose styles of child controls it encapsulates to the ASP.NET designer. The code I currently have is similar to the skeleton below (which for simplicity only has one child control).
With the code below, I can see property "ChildPanelStyle" in the designer, but when I try to modify one of the properties (e.g. CssClass) in the designer, it immediately resets itself to its default value. It looks like the designer serialization isn't happening.
What am I doing wrong?
UPDATE
I've updated the sample with an additional style property that is managed directly by the custom control, rather than simply being the property of a child control.
The HeaderStyle property is persisted properly by the designer, but the ChildPanelStyle property isn't.
Of course I could manage all my styles like HeaderStyle, and apply them during rendering, but I'm hoping there's a simpler solution whereby child controls can take care of themselves, and I don't need any custom rendering.

Custom Server Controls :: Composite User Web Control - Properties - Best Practice
Jan 12, 2011I would like to ask you what is the best practice for developing composite user web control with multiple controls inside from the stand point of dealing with properieties. In my situation I would like to use header menu bar with logos, buttons, java baset visible/hidden menus itc as web control. I was successfull in implementing new control in my project.
But my question goes to issue of properties for ALL OF controls. I know how to hard code all required properties like: text, visible, enable for all controls. It's a lot of work. ( This is the very edge of my asp.net comprehension ) Is there a more elegant way provide an access to controls's properties without hard coding seperatelly?
C# - Load A User Control In An Ajax WCF Service And Access Custom Properties?
Apr 4, 2011I can load a generic user control just fine in my WCF service doing the following:
UserControl userControl= (UserControl) new Page().LoadControl("~/UserControls/MyControl.ascx");
However i can't seem to find any way to do this
MyControl myControl=(MyControl)userControl;
The reason i need to do this is because my user control has a custom property, person, I need to do the following:
myControl.Person=new Person();
essentially i need to simulate:
<%@ Reference Control="~/UserControls/MyControl.ascx" %>
which normally goes inside asp.net page or master-pages.any way of doing this in an Ajax Enabled WCF Service?
Does A Composite Server Control(inc. User Control, Custom Server Control) Normally Encapsulate Css Properties?
Nov 7, 2010If a composite server control normally encapsulate styling information inside, it is an example of code encapsulation and modularization. However if css properties are included inside the composite control, it is not ideal for code/styling separation and css code re-use principles. Now which consideration should be the main consideration?

View 2 RepliesCustom Server Controls :: Accessing Properties Of A User Control From The Inherited Code Page?
Mar 8, 2010If the answer to this question exists somewhere, I'm no good at searching for it. This is sort of a simple question, the response being two parts: (1) is it possible? (2) if so, how?
I've created a web user control for my site's footer. In my web.config I have it registered like this:
[Code]....
Then, within the pages on my site, I simply insert it like this:
[Code]....
But obviously, that didn't work. I get this error: The type or namespace name 'FooterControl' could not be found (are you missing a using directive or an assembly reference?)
So I'm really not sure what to do at this point. I can put all of my code in the ASPX file and make my life easier, but I would kind of prefer not to.

Custom Server Controls :: How To Get The Value Of Readonly Properties Of Server Controls Inside A Custom Server Control
Apr 4, 2010I have a custom server control inheriting from CompositeControl. It consists of two RadioButtonlist controls that are rendered side by side in an html table. The number of ListItems in each RadioButtonList is not known until runtime. Depending on how many items each list contains, the RepeatColumns property of each list is set differently. To do this in the handler for the ItemDataBound event I need to get the count of ListItems in each RadioButtonList. How do I expose the Items.Count property of each internal RadioButtonList as a top-level property? I tried using a getter to return the count but this generates a compile-time error to the effect that the count cannot be assigned to--even though I have not created a setter.
Similarly, in the handler for the Submit event, I need to get the ClientID of each internal RadioButtonList to pass to a method that checks for data changes. How do I expose the ClientID of each component RadioButtonList as a top-level property?
I can of course index the Controls collection of the composite control to access the child control and read its properties--but that defeats the whole point of making a complex, independent custom server control.
Web Forms :: Setting Page Properties From Itself?
Oct 8, 2010Is there any easy way to set properties of a Page (or UserControl for that matter) from *within itself*?As an example, I have several .aspx pages which inherit from exactly the same code-behind class, but I need to be able to pass different properties to the class to make them do the correct thing for the specific .aspx.
The only way I've found to do this is to create the following - which works fine, but doesn't feel right....
<script runat="server">
Private Sub Page_Init(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Init
Me.MyProperty = True
End Sub
</script>
It would be a much nicer, simplier and easier solution to be able to be able to set MyProperty = True somewhere... is this possible?The option of hard-coding properties within the class for the "parent" page is not going to work for my situation.
