Get UserControl VirtualPath Programmatically?
Sep 15, 2010I need to get a UserControl VirtualPath programmatically. How can I do it?
For example, MyControl.ascx placed in Controls folder, so the result should be "~/Controls/MyControl.ascx".
I need to get a UserControl VirtualPath programmatically. How can I do it?
For example, MyControl.ascx placed in Controls folder, so the result should be "~/Controls/MyControl.ascx".
I want to be able to add the same Usercontrol by code more than once, when I click a button.
I use this code to load my custom usercontrol:
Private WithEvents MyStatus As controls_MyStatus = CType(LoadControl("~/controls/MyStatus.ascx"), controls_MyStatus)
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Panel2.Controls.Add(MyStatus)
End Sub
the problem is that the usercontrol is only added once
I have a UserControl that I need to add dynamically. I tried to follow this MSDN article, but I'm not having any success....[URL]
The UserControl is basically an image gallery, and it loads some pictures based on an ID. My idea was to make this ID available as a property. Then when I create an instance of the control, I could set this ID and add it to the form.
I added a reference to the control in the .aspx page that will use it, like this:
<%@ Reference Control="~/PictureGallery.ascx" %>
And in the UserControl I added a ClassName like this:
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="PictureGallery.ascx.cs"
Inherits="PictureGallery" ClassName="PictureGallery" %>
When I try to create an instance in the .aspx.cs like the article suggests, Dim gallery As ASP.PictureGallery, I get an "Type ASP.PictureGallery is not defined".
The article mentions a namespace, ASP, and I tried importing it to the .aspx.cs with no luck. So, I'm not able to get a reference to the UserControl.
UserControl: How to set Output Cache duration programaticaly?
View 2 RepliesI have a page that dynamically inserts user controls into a placeholder depending on values in a database table. The user controls consist of a label and one control (dropdownlist, radiobuttonlist, or checkbox). The controls will also have the AutoPostBack property set programmitcally depending on values in the database. My update panel is on the main page, not in the user control. I have tried the ScriptManager.RegisterPostBackControl method to register the UserControl on page load, but the page still does a post back. I think I need to register the control that is inside the UserControl, but I have no idea how to access it from the main page_load event.
This thread is the closest to what I am trying to do, but since I am inserting the user controls programmatically, I need the triggers to be registered programmatically as well. Also, I need to register
them as PostBackTrigger instead of AsyncPostBackTrigger because I need to do a full page reload because the user controls are inserted dynamically.
I have a usercontrol hosted on a page, registered through the web.config.
On the host page, I would like to programmatically reference the my public propeties of the user control in the codefile.
My virtualpath provider works well in VS 2010 but doesn't in IIS 7.5 on my localhost. In IIS, I get a HTTP 404 when I fetch an aspx, which is normal because the aspx is in a table. The problem seems linked to the sequence
HostingEnvironment.RegisterVirtualPathProvider(new MyProviderClass) in the AppInitialize method.
There is no exception raised but the instruction seems to no avail :
If I try object O = HostingEnvironment.VirtualPathProvider immediately after the registering, I see that O==null.
Again, it works perfectly well in VS.
Im using this code below, but it does not work. I am NOT specifying the "PreviousPageType VirtualPath" in the page, as I want to be able to post to this page from multipul different pages. It finds the placeholder ok, but the control collection for that placeholder is empty so the textbox is never found.
I want to be able to post to this page from many pages that are created using the custom error page. So I cant really specify the "PreviousPageType VirtualPath" as it can be many places all of which are not physical paths

I've a ASP.Net page (Default.aspx) which will load UserControl (ucontrol.ascx) dynamically into an UpdatePanel. By using UpdatePanel, we believe we're able to prevent the entire page to be posted-back.
My problem is, within the UserControl, we have some form controls, such as inputs and buttons; after the UserControl is loaded, clicking on any button inside the UserControl will cause the UpdatePanel to be blanked. During the investigation, I found that, breakpoints within the Button1_Click() in the code-behind for the UserControl is never reached. Please reference to the code below, this references to [REFERENCE]1.
[code]....
This is page load
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{ [code]...
But in my ascx.cs when IButton1_Click is trigered My name is null
private string _sname;
protected void Page_Load(object sender, EventArgs e)
{ [code]...
I have a page with an UpdatePanel with a UserControl in it. That UserControl contains a GridView with a nested UserControl that seems to disappear when the parent UserControl is rebound. I cannot for the life of me figure out why the child UserControl disappears. The code works beautifully on the first load, but any partial postback causes the "Pick" UserControl to disappear.

im creating site with usercontrols. I have repeater, inside it is another repeater with usercontrol. My problem is passing BindedValue to usercontrol.Bindings works fine and binds the value i need but it cannot pass the value to usercontrol. When i type it manually it works, when i bind it, it passes null (!).I've tried get,set, functions (ondatabound, onload, oninit), accessing control from code with no luck. Ive read and tried to do all the google solutions but with no luck. (even with creating usercontrol inheritance)
View 5 RepliesThere are 2 UserControls UC1 and UC2, and there is one more class C. I want to share the same instance of c in both UserControls. I know that this can be possible with properties in both UC's and by registering UC2 in UC1 or vice versa. But I want the solution to be loosely coupled. Any best possible way without touching the Actual Page (which hosts UC's)? So i need some best possible way between UCs transfering C.
View 5 RepliesI have MainLayout.master that has UC_Menu.ascx on it.
I have a page named Customer.aspx that uses MainLayout.master. Customer.aspx also contains a UserControl named UC_Details.ascx.
How can I have UC_Menu.ascx call a function that is in UC_Details.ascx with this scenario?
I've seen a few similar examples, but none that match this type of layout.

I have 2 usercontrol in my .aspx page.

<asp:textbox id="txt" runat="server"></asp:textbox>
<asp:button id="btn" runat="server" text="send" />
usercontrol2:
Here I have gridview control with checkbox for selection of one or two records. Have one button and when clicking this , i need to get the selected records values and assign this values to the textbox which is in usercontrol1.
have a webpage that has a button and 2 userControl placed inside the placeHolder with visible set to false.When run and click on the button, userControl1 will set the visible to true. Now userControl1 is visible and there is also a button inside this userControl1 and when click, will set userControl2 visible to true and hide userControl1. The code below is the code behide for the webpage the do the above task.
[Code]....
Is there a way to do so that when click on the button inside userControl1, is does not show userControl2? I want to do this way is because, the button is for submitting data to database and then will pop up userControl2. When there is an error, only a msgBox will pop up and does not show userControl2.
I have two UserControls on a MasterPage. DataEntryUC contains several TextBoxes and DropDownList. NavSaveUC contains navigation buttons. When the user clicks on a navigation button, I will be saving the data entered into DataEntryUC from the NavSaveUC UserControl.
I have a couple of tables in my DB that contain stored procedure names, control names, control types, SqlDbTypes, etc.... that correlate with DataEntryUC.
How do I reference a text box that is on DataEntryUC from NavSaveUC?
I have been working on the following code from NavSaveUC with no luck.
Dim MyControlName = "txtFirstName"
Dim MyControlType = "TextBox"
Dim MyStringValue as String
Dim tmpTxtControl as TextBox
Dim tmpDdlControl as DropDownList
Select Case MyControlType
Case "TextBox"
tmpTxtControl = CType(Page.FindControl(MyControlName, TextBox)
MyStringValue = tmpTxtControl.Text
Case "DropDownList"
tmpDdlControl = CType(Page.FindControl(MyControlName, DropDownList)
MyStringValue = tmpDdlControl.SelectedValue
End Select

View 1 RepliesI want to register an UserControl in another UserControl but i have some errors like :
Control '4_txtCount' of type 'NumbericTextBox' must be placed inside a form tag with runat=server.

Controls_SearchFeaturedMerchants UCMerchant = (Controls_SearchFeaturedMerchants)this.Parent.FindControl("UCSearchFeaturedMerchants1");
I have an app, where I have a form including 50 equal lines (50 user controls).
How do I set the css in the usercontrol, so e.g. the droplists-colors are different in line 1 and 2 (alternating)?
The way I have it now the 50 lines will we completely equal
