To Handle A MasterPage Event In A UserControl (C#)?
Aug 19, 2010
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
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 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); }
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.
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 want to develop a user control (by inheriting UserControl) which contains a button which when clicked does multiple actions. Those actions should be defined somewhere. So when I sue the control on page1.aspx the button does action X, when its used on page2.aspx and the button is clicked there, action Y is started and so on.
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?
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 wanna write a usercontrol to handle different access levels on pages.
Below is the html i wanna achieve.

My problem is that the <Content> and <AlternativeContent> doesn't get rendered as Panels and on the Client side its rendered as the initial tags(<Conten>) and not a div or whatever a asp:Panel normally gets converted to.
I have a masterpage and inside that masterage is a user control that has a toolbar with a save button. I then have an aspx page that inherits form t he master page. In that page I have and updatepanel. Is it possible to set the post back trigger to the Save button inside the usercontrol?

In my View, there is a HTML button; I would like to execute a function from Controller when user clicks on that button. I need to pass a value from HTML textbox as parameters. My function will do some calculating and return the result back to the same View.
Let's make a simple example.
I would like to input "1" in my textbox, press the button, pass "1" to controller, and in the function, I will do something like 1+1. At the end, I will pass the result, which is "2" back to the View.

I am having a treeview with nodes of products populated on first time through xmlresponse.Onselectednodechanged event, I have performed xmlseriaization to build a request to get list of subproducts. Now, my issue is how do I handle the next On_click event requesting for items under subproducts which will inturn calls the same onselectednodechanged method and how do I write condition to skip above steps to occur, since I need to build a different request on click of subproducts asking for items.
i just made an onmouseover and onmouseout event using javascript and called the functions from the asp image tag like <contol.....onmouseover="thissss()" /> my question is why do i need to write javescrit for this? have heard so much praise of asp.net and c#! is there a way that is code to handle these events for all types of object using the .cs file (c#) directly?? i would assume the code will be under the page load event.
note:-
do not give answers assuming that the asker is a new bee consider him a completely un-educated person when it comes to coding )

I am writing an asp.net HTTP module which needs to read configuration data once from a local file (say config.xml stored in application root directory) and then based on configuration perform some processing on incoming requests.
Since there is no Application_Start/Application_init hooking available in Asp.NET modules, what would be the best way to handle the scenario. I am trying to avoid reading configuration file each time a request comes. Ideally, I want to read the config file when application starts.
I need to code this in http module only and do not want to use Global.asax
