Web Forms :: Programmatically Add Usercontrol More Than Once?
Jan 11, 2011
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.
I 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.
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)
There 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.
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'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.
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.
I have a UserControl, which contains another UserControl with Button. I want to add an event to that button in first UserControl (parent). I tried to do:
void Page_Init() { var btn = ChildControl.FindControl("SearchButton") as Button; btn.Click += new EventHandler(this.SearchButton_Click); }
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
I 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.
Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Web.HttpException: Control '4_txtCount' of type 'NumbericTextBox' must be placed inside a form tag with runat=server And when i add a server side from tag in my UserControl, i never get the error message.
How can i register and use an UserControl in another UserControl without adding server side form tag in UserControl?
I want to add and use the user control at runtime in the master page.
I have used LoadControl Method to add usercontrol but in that case i was unable in getting the tagprefix and tagname value of the user control so that i can use it on master page file also.
i designed an user control within that one html textbox input control is there. now i want to drag and drop this usercontrol into an aspx page, my doubts is how can i validate that user cotrol html input control has data or not using javascript? then im want to read that data from aspx code behind, how to do this?
User controls when rendered generates a dynamic ID for themselves. It makes sense also, as a page might have more than one of such user control and if dynamic id is not generated, there would be an ID conflict. But I am working on a page (legacy page yopu can say :D ) where I really need to specify a specific ID to usercontrol to make existing javascripts work. Is there a way to achieve this? OR if above is not doable (though I prefer it), below I have a dropdown in aspx like
