Web Forms :: Access User Control Properties In Another User Control
Nov 9, 2010I want to use a couple of instances of the same control on a page. The user control is intended to display a list of records in a repeater. The aim is that the second control will show a list excluding the IDs in the first control The control has a number of public properties, including IDsInThisList, and IDstoExclude. The query will exclude the IDs in the second property.
What I would like to do is get the record IDs from the first instance of the control (IDsInThisList), and pass them to the second contro as the IDsToExclude.
I have a test page where I am setting the properties of the controls in code. As you might guess, it's not working! The first control displays the top 3 items, as desired, but the second display the records 1-7, rather than records 4-10 because it is not receiving the IDstoExclude from the first control When I response write the IDstoExclude from the first control in my testpage, the string is empty. (if I do it from within the control, it shows the IDs)
How can I get the controls to fire in order and pass values to each other?
Screen grab of test page + uc and test page code attached

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?

View 3 RepliesWeb 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:

Web Forms :: Personalization Properties Inside User Control?
Mar 19, 2010I have a webpart that loads in a user control programmatically. Although the webpart has personalization properties that I can use and pass to the user control, I haven't found a way for the user control to be able to update the outer webpart's properties -- the user control knows nothing of its parent webpart except what it is given. When I try to use the [Personalizable] attribute on a property inside the user control, it doesn't work; it doesn't save anything to the personalization database. In a nutshell, I need the user control to be able to personalize its properties (e.g. for a date picker within the user control where the date has to be remembered between sessions) or to somehow be able to update its parent webpart's properties.

Web Forms :: Reusing Class Properties Invoked In Masterpage In A User Control
Feb 2, 2010I'm working on a project that uses a master page. When the page loads I'm calling a class (which I feed and ID into) to get back certain values for a location that the user has selected. Things like town name etc.
On the home page I have a user control which has some statistics for that location too.
Is there a way that I can get the user control to pull values from the class invoked by the Master Page (which has already been fed the ID, hit the db and pulled back the values), rather than creating a new instance of the class within the user control and having to supply the ID and hit the db all over again? This is now I'm calling the class in the masterpage. I have a method "CheckForStoredLocation" that goes off and gets all the data I need.

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?

Create ASP User Control With Inner Properties Used With Markup Similar To UpdatePanel?
Nov 5, 2010I am creating a user control that I wish to have inner properties as well as normal attributes. Although the actual function of the control has nothing to do with, say, UpdatePanel, I am trying to create something with similar ASPX markup. The developer designing the page should be able to use my control like:
<ns:MyControl ID="someID" runat="server" SomeOtherAttribute="true">
<ContentTemplate>
<asp:Label ID="someLabel" runat="server" Text="Normal page markup and controls should go here" /><br />
<p>This should be OK too.</p>
</ContentTemplate>
<ControlEvent ControlName="idOfOtherControl" Event="Click" />
<ControlEvent ControlName="idOfSomeOtherControl" Event="MouseOver" />
</ns:MyControl>
Also acceptable would be wrapping the ControlEvent tags in some other tag, more like what happens when using UpdatePanel:
<ns:MyControl ID="someID" runat="server" SomeOtherAttribute="true">
<ContentTemplate>
<asp:Label ID="someLabel" runat="server" Text="Normal page markup and controls should go here" /><br />
<p>This should be OK too.</p>
</ContentTemplate>
<ControlEvents>
<ns:ControlEvent ControlName="idOfOtherControl" Event="Click" />........................
