Web Forms :: Embedding User Control In Aspx Page Through Tag?
Oct 5, 2010
I have a windows user control simpleusercontrol.ascx which has a button control which when clicked calls a delegate method as shown below:
[Code]....
Now this control is embedded inside an aspx page by using <object> tag i.e. by creating a dll of the above project. (Please note that it is the requirement of the project as javascript needs to be called from the embedded windows user control onto the hosting aspx page).So,
[Code]....
This works perfectly fine when I run the project in VS.Net by pressing F5 ie by using VS.Net inbuilt web server. However problem arises when I try to run the same project by creating a virtual directory and calling through localhost.

Right now i am creating .html page dynamically and including in iframe of aspx page. it works fine ,but when i deploy it.on using https://I am getting errors in IE8 .. It works fine with IE7 and Firefox,so instead of giving the html file as source to iframe.., i want to try showing the html directly on aspx page.. rather than giving as a file..
Below is my code..
</fieldset>
<iframe id="abc" runat="server" height="650" width="800" align="middle"
frameborder="3" scrolling="no" style="border: medium double #808080"
enableviewstate="False"></iframe>
abc.Attributes("src") = "/PDFs/" & rndFileName & "_First.html"

I've embedded multiple user controls into the same page. The user controls typically have 2 different views, an edit/default view and a completed view. When the user completes an edit then I switch the MultiView to the completed state. This pattern works okay in pages.
The problem is when I go back to the master view/page then the user brings back the control, the view is still in the completed state.
What are some simple methods for resetting/correcting the multiview state? I could have a Reset() function on every control but it feels like I may be able to avoid that.
Update:
This page is designed to show an account/profile view and it has the following parts:
<asp:MultiView>
...read only view
<asp:EmailEditView>
<asp:AccountEditView>
etc..
And then each of those views has a user control. Inside the user control, we have something like this
<asp:multiview>
<asp:view id="edit"/>
<asp:view id="completed"/>
I've found the following problems with this design:
When the user completes an action of user control such as changing an email. The view stays in the finished state even when they go back to it a second time. When the user goes back to the original form the data is stale. This design really screws with the postback mechanism. If I don't use !IsPostBack on the main form for databding then my dropdownlist on the sub forms will not work. However, once I add the !isPostBack on the main form then the data becomes stale.
I can add a "reset" flag to every user control and add something like this
if ((!IsPostback) || (reset) )
As well as resetting the view. In the other scenario, I can add an event handler to load the reload/bind the data when the user clicks "back", i.e where I change the form back.

I'm trying to programmatically add a user control to an aspx page.
the problem is that any postback that happens on the page(even if i added the user control to an updatepanel) clears the user control from the page.
this happens also if the postback is generated from the user control itself.

I am working on a page called Edit.aspx and on that page is a User Control.
Note: I need to access the User Control from a button that is on the Edit Page. Once I get a handle of the User Control then I need to access a DataList on that user control and finally I need to get the ID of a dropDownList
on the User Control
This is all the code I have,Goal: From the Edit page I want to drill backwards to the UserControl/DataList/DropDownList
'Geting the user control
Dim ctrl2 As UC_SiteTemplate2 = CType(Page.LoadControl("~/UC/SiteTemplate2.ascx"), UC_SiteTemplate2)
'accessing drop down list from user control
Dim xListNumber1 As DropDownList = New DropDownList()
xListNumber1 = ctrl2.FindControl("DDLOrderList1")

There is one user control say uControl.ascx. This has a public property Message. There are 2 aspx pages Default.aspx and Home.aspx which has the user control uControl.ascx. When a sumit button from Default.aspx is clicked some action takes place and the value for Message is set and then execution is redirected to Home.aspx. In Home.aspx the value for Message is lost.
Is there anyways that the value of Message is retained for both the aspx pages?

I have a need to improve the asthetics of the standard buttons .net churns out. I am fully aware of how to do this using css but I can only really style the button if I add a span element inside the button. Luckily the link button allows this so I have got the following which for usability i have put inside a user control.
<linkbutton><label>button text</label></linkbutton>
I have exposed elements so that I can set values from within my aspx.cs page, these are text, command name, command argument, ccc class etc.
As it is a generic control, I have added OnCommand='Button_Click" which fires the event in the control itself. The Button_Click event calls a method ButtonControls passing associated command name and arguments across. ButtonControls uses the name to call the appropriate function.
As these are all very generic buttons, so far so good, but I have a need to trigger button events that may not be generic i.e on a control I have buttons that do something very specific to that control. I also have a requirement to call functions which relate to specific controls on the aspx page. I have created a user control which encapsulates the link button control.
Click triggers > Button_Click > ButtonControls > MethodToCall
sometimes I don't want to call Button_Click just an event on the aspx page itself rather than my generic button handler.

I have an aspx webpage in which an user control is added dynamically as follows:
UserControl testUsrControl = LoadControl("TestUsrControl") as UserControl;
testUsrControl.ID ="test";
Then I tried adding an event handler of user control inside aspx like below:
testUsrControl.Drpdatafield_SelectIndexChanged += new EventHandler(this.Drpdatafield_SelectIndexChanged);
But this line is giving error at **testUsrControl.Drpdatafield_SelectIndexChanged **. The error is "Drpdatafield_SelectIndexChanged" doesn't exist in UserControl.How can get the testUsrControl's events inside aspx page dynamically.

Here is my requirement -
1. I need to load a user control on link click event of a link button during postback of aspx page.
2. On button click event of a save button on that aspx page, I need to read the selected values from that user control on further postback.
If I write the loadcontrol code in link_click event, the control is not recognized at all in the button_click event. When I shift it to page_init and execute only during not postback, the user control loads with default values.
