It's simple to create both user control from the two world : ASP.NET+Razor or MVC 3.0.But i do not known how to consume the user control FROM the razor"_layout.chtml" page.I want to put such thing within the layout page: <uc:MyTag Prop1="" Prop2="" />So i need to declare this directive at top of the layout file : <%@ Register TagPrefix="uc" TagName="MyTag" Src="Controls/Mytag.ascx" %>
View 1 RepliesI've got a web site that has a master page and that master page (mpMaster that has a user control ucControl1) which has a sub user control (ucControl2), this user control has a property which accepts a value. Now, I have a page that uses the master page
and on this page I have another user control (ucPageControl), I need to find a way of setting the value in ucControl2 from ucPageControl. Is this possible at all?
i would like to ask about how can i open user control page when i click a button on parent page, also, can i call parent's method from user control page and then refresh parent page?
View 8 RepliesI don't think I understand fully how ASP.NET does inheritance of controls.I have a user control, ucBase, which has an asp.net label in the ascx file. Code behind references the label and it works fine during run time if the control is not a parent for another user parent.
If I have another user control, ucChild, inheriting from ucBase, the label in ucBase's code is always null. ucChild has no controls in its ascx fileThe server controls (like the label) needs to be declared in the ascx file and not created programmatically.What needs to be done for ucBase to see its own controls when it's a parent user control?
I have a user control which contains a number of child controls. I want to be able to change the layout of the control (i.e. change the markup surrounding the child controls) via a property of the user control, but I don't want to have to duplicate the child controls themselves. This precludes using, say, a MultiView with different versions of the layout in each view, since in that case I'd have to duplicate the controls. I'd also rather use markup than emit the code for the control directly (as you'd do in a server control).
To give a contrived example, say I have a label and a textbox. In one layout, I want the label and textbox to be contained by divs and laid out on top of each other. In an alternate layout, I want them to be contained side by side in a table.
Should I just go ahead and duplicate the controls between each view? It seems like a violation of the DRY principle, but I'm not sure if I have much choice. A partial solution would be making the views of a multiview into naming containers so that I could at least save myself the time of having to prefix the duplicate control IDs with something to make them unique.

View 2 RepliesI have a user control that contains an image of a product along with some product details.
If the product image is landscape, I want to render the control one way, and if the product image is portrait, I want to render the control a second way.
Example HTML Layouts (drastically simplified):
<div><table><tr><td>
<p><strong>XXXXXX</strong></p>
</td></tr><table></div>
versus
<div><table><tr><td>
<p><em>XXXXXX</em></p>
</td></tr><table></div>
Right now, both layouts are rendered. How can I conditionally render one layout and not the other?
I have a user control I'm building that has a table layout with two sets of radio buttons, like:
how I could use a radiobuttonlist for each set of vertical buttons within this layout, unless I used a rowspan on each col, but that seems problematic from a layout perspective? I would rather use a RBL from a programming standpoint.
If I instead used a set of radiobuttons with a groupname for each, how do I get/set the selected button (for each set) from outside the UC?
i have:
- Default.aspx;
- user1.ascx: 1st user control containing repeater;
- user2.ascx: 2nd user control containing a detail view of row.
In page.aspx i dinamically load the repeater inside a user1.ascx.
after i want to dinamically load the 2nd user control also in default.aspx by a button inside a user1.ascx.
How i can do this? I can't load user2.ascx inside user1.ascx but only in aspx page.

View 4 RepliesI have a web user control that represents a simple message box. It is used to display simple messages like "Item has been deleted", or "The item was saved successfully".
On the other hand, I have another web user control that represents the item in the form of an editable form (I made this a user control because this is used in two different pages). I want to embed an instance of the message box user control inside the editable form. I am writing this right after the @Control directive:
[Code]....
Instead of using @Register directives, I register the user controls in web.config and so far this has worked just fine.
With the above markup, the project compiles, but whenever I try to navigate to a page that contains this construct, I get an HttpParseException exception. Furthermore, Visual Studio states that the tack w7rc9:MessageBox doesn't represent a known control.
What am I doing wrong?

View 1 RepliesAll I would like to be able to do is include one user control within another! Is this possible? I have spent the last hour searching the internet and it seems that I can't find a single thing.
In classic ASP it would be something like:

I tried this but no luck!

In my default.aspx page I have a PlaceHolder control within an UpdatePanel. In this placeholder control I will dynamically load a web user control, which is just a form with a submit button. On this user control, I have the form within an update panel and I have the "Submit" button's Click Event added to the triggers.
When I submit the form, the UpdatePanel on the web user control nor the update panel on the default.aspx page are capturing the post back, thus causing a full post back which refreshes my page.
how to capture this post so its rendered in Ajax and not a full post back?
I have on dropdown that show hide user control. In the user control i have Ok and Cancel button.
When the dropdown change i want to apply ValidationGroup on the Ok button that is inside UserControl.
I have a label on my master page (called mainMenu) that shows the number of items in a cart. The label wasn't getting updated when the cart was cleared until after an additional postback or redirect so I created a method on the master page called UpdateNumberOfItemsInCart to update the label text.
Using the MasterType directive on the Cart page allowing me to strongly type the master page, I can access the update method from the Cart page. There is a user control also named Cart that actually contains the 'clear cart' button so I setup an event on the user control also called UpdateNumberOfItemsInCart. I wire up the Cart control's event on the Cart page which then makes a call to Master.UpdateNumberOfItemsInCart();
So far so good except when I wrap the Cart control with an update panel the update to the cart count label doesn't happen.

I have an asp.net usercontrol which represents a "popup" dialog. Basically, it's a wrapper for the jQuery UI dialog which can be subclassed to easily make dialogs.
As part of this control, I need to inject a div into the page the control is used on, either at the very top or very bottom of the form so that when the popup is instantiated, it's parent is changed to this div. This allows "nested" popups without the child popup being trapped inside the parent popup. The trouble is, I can't find a safe way to inject this div into the page. A usercontrol doesn't have a preinit event, so I can't do it there, and calling Page.Form.Controls.Add(...) in Init, Load or PreRender causes the standard exception "The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases."
I thought I had found a solution by using...
ScriptManager.RegisterClientScriptBlock(Page, Me.GetType, UniqueID + "_Dialog_Div", containerDiv, False)
... which seemed to work well normally, but recently a coworker tried putting an UpdatePanel inside the dialog and now she's getting the error "The script tag registered for type 'ASP.controls_order_viewzips_ascx' and key 'ctl00$ContentBody$OViewZips_Dialog_Div' has invalid characters outside of the script tags: . Only properly formatted script tags can be registered."
