I 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.
Senario: Masterpage with a UserControl and a child ASPX page
In the past when using this senario I've used an Interface as a way to pass a value from the UserControl (embedded in a master page) to the masterpage code behind then consume that value in the child aspx page.
My question is now that asp.net 4 have arrived is this still a good way to achieve this or is there another or perhaps better way to do it? I've read somewhere that perhaps "delegates" is perhaps another route to take.
i have an button click event on the aspx page, the same aspx page load event i have hide the user control if the Session["Userid"] is empty, now the user can login from the same page, so after his successsfull login i show the usercontrol(in this user control i'm just show a Welcome message and logout button -in this user control also im checking if the userid is not found then hide the welcome message), but there is no data because while page load there is no data on session, so how to reload the usercontrol.

View 1 RepliesI am having a Calculate() function in user control which is inherited in a page.
I need to call this method in the button click event in the page.
On MasterPage i have function below, how call this function on test.ascx form on button click.
public void HideBtnLogin() { string session = Session["userCode"] as string; if (String.IsNullOrEmpty(session)) {
lbtnSignInTop.Visible = true; lbtnSignUp.Visible = true;
}
else { lbtnSignInTop.Visible = false; lbtnSignUp.Visible = false; } }
I have the following situation:
A MasterPage MyMaster.Master
A Content Page Content.aspx
A UserControl MyUserControl.ascx
MyUserControl.ascx is being used in Content.aspx and is being added programatically. The content page is using MyMaster.Master
MyMaster.Master has a variable which I can access from Content.aspx as I have the @MasterType directive set. What I am wanting to do is the following:
1) Set a value in MyUserControl.ascx
2) Access value from Content.aspx
3) Set value in MyMaster.Master
Step 2 is implemented in the PageLoad of content.aspx as follows:
Control ucControl= LoadControl("/UserControls/MyUserControl.ascx");
UserControls_MyUserControl myUC = ucControl as UserControls_MyUserControl; [code]....
The PreRender handler just sets a value in MyMaster.Master to true. In MyMaster.Master I check that value in PageLoad and try display something if it is true. This does not work.I suspect it has something to do with the Page Lifecycle, but I cannot seem to find which part is wrong.
I've seen code to handle MasterPage events in the content Page, but if I'm loading a UserControl dynamically into the Page, can I handle the event in the UserControl instead?
Basically I have a button on the MasterPage, when it's clicked I need to make the UserControl do something, such as display text or change a value in a form.Failing that, is it possible to make an event from one dynamically loaded UserControl fire in another on the same page? I could then replace the button in the MasterPage with one in another UserControl
I have Page, MasterPage and UserControl in my project.
So I create basepage class and share some logic, then inherit from System.Web.UI.Page. My problem is I want use single basePage for any type of UI content.
I'm fetching some settings out of the database based on a value passed from a query string. Out of these settings, a few will be used in master page, few on my Page and few in my user control (say login control which is a web user control).I've an entity class MySetting for it and there is a method in my data access layer which returns me an instance of MySetting when I pass the value I got in query string.
I don't want to fetch settings from the database multiple times for one request. I'm using asp.net web forms with C# and sql server.
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 usercontrol (ascx) with a DropDownList placed on a MasterPage. It has AutoPostBack=true. I created a SelectedIndexChanged event for the dropdown on the usercontrol, but it does not fire when seleted item changes. The PostBack fires and both current page as well as MasterPage are reloaded but the SelectedIndexChanged is not fired. How can this event be trapped?
View 8 RepliesI 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.
