Pass Values From MasterPage UserControl To Child ASPX Page?
May 4, 2010
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 a masterpage and 1 childpage. In master page there is a listbox to present a data when a child page button is clicked. Listbox name is x1 for example.
When i am in childpage's button click event: i do not see that x1 named listbox due to namespace i guess.
For example masterpage name is masterpage1. When we are in childpage in button click event.
To try masterpage1 objecttemp = new masterpage1()
button1_Click() (child pages button click event)
masterpage.x1.items.add("button 1 clicked"); it is not being able to reachable too.
Also i encountered another issue related to that. When in masterpage for example masterpages click event. (its a login panel and when user clicks login, i had wanted to add a text information to listbox). In child pages when user clicks to login button which belongs masterpage top panel. It does not seem like working. It may be related to asp page master child life cycle and i do not know good. I wanted to able to add a string to listbox that belongs and come from masterpage in child page. Is there any way to use a datacontrol in childpage that belongs to masterpage.
I have two files in my project. One is user control (popup) customerpicker.ascx and one is default.aspx page. In customerpicker I have dynamically generated gridview and 'select' column with SelectButton.
What I want is this: When I click on 'select' on random row in gridview, then I like to display value from selected row immediately (like ajax) to aspx.page. How it is possible?
For example, I have master page MyMasterPage.aspx and content page MyDefault.aspx. I have many UpdatePanels at MyMaterPage.aspx, and also I have many UpdatePanels at MyDefault.aspx.
[code]....
I want JavaScript functionClickMenu(this) at input button [id="ButtonMaster1" @ MyMasterPage.aspx] pass its value ["Menu-1"] into text box [id="TextBoxDefault1" @ MyDefault.aspx], and then performing update / doing post-back to server ONLY FOR UpdatePanelDefault1.
I am looking forward an example code for JavaScript functionClickMenu(this).
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.
Can anyone tell me how to do this? I cannot put it straight into the master page as it conflict with some other javascript code that I am running on a different page! And I cannot put it into the body of the child page because it does not function correctly.
I have a ASP.NET C# 3.5 web application, where I am changing the masterpage & theme for certain pages that have ASP.NET controls. The problem is that when the masterpage/theme is changed, the ASP.NET ImageButtons on the child page cease to function altogether and show up as normal images. The html source for that page would show a disabled="disabled" field added to the ImageButtons at runtime. All other controls including ASP.NET Buttons work fine, only ImageButtons are effected. I've changed masterpages in files many times and have not come across this problem, probably because I rarely use ImageButtons. I'm beginning to think it may be a bug in .NET itself, but it could be code related. I've also executed a javascript function after load to set the disabled field to "enabled", which has no effect on the ImageButton but the source confirms it is enabled. The MasterPages / Child Pages are relatively straight forward and I've tried many different combinations to get it working. I'm changing the masterpage & theme via a function like:
I'm embarrassed to ask this here because it's clearly been duplicated several times already on StackOverflow. I've read a lot of stuff including:

I think I've done exactly what those article say, but it's not working for me.
Here's the top of my master page, named "MasterNoNews.master":
[code]....
In the first case, VS is telling me System.Web.Ui.MasterPage does not contain a definition for urrentUser. In the second case, VS says the type or namespace 'MasterNoNews' could not be found.
If for example my userControl has a CheckBox called IsGreatCoder and the userControl is embedded in a main page (parent page).
I normally have gained access to the IsGreatCoder.Checked value in the main-page by exposing it through a public property that I have to manually write (say "IsAGreatCoder").
If UserControl is included in the main page as "userControl1", then I would access it as "userControl1.IsAGreatCoder".
But, I was wondering if there was anyway to declare the UserControl such that all the UI controls added to it were declared as being public, that way allowing me to gain access to the actual controls in the main page (the parent).
Essentially I would like to be able do something like userControl1.IsGreatCoder.Checked instead of having to implement a property.
The reason I want to do this is that I want to have access to many more of the check-box's properties and it would be a pain to implement each one as a public property.
I've got a pretty simple problem but I am not sure what is the best way to accomplish this. I've got an input aspx where a user fills in about 15-20 input fields and I want to display this information on the next page however; I am not really sure what is the best way to go about doing this?
I tried using 'Server.Transfer' and 'FindControl' API calls but have struggled to use them because the value is always null because it cannot find the asp:textbox ID I have specified from the previous page.
What would be the best way to just simply transfer the values from my previous page to the next page??
I have 2 user controls that is hosted by 2 different aspx pages.
example:
srcpage.aspx --> hosts the --> sourceusercontrol.ascx and destpage.aspx --> hosts the --> destinationusercontrol.ascx
I would like the values in the text fields of the sourceusercontrol.ascx to be passed on to the labels in the destinationusercontrol.ascx.
I have gone through the MSDN ASP.Net examples and i was able to successfully pass values between two aspx page using the postback URL functionality, but cannot do the same thing with the usercontrols on 2 different aspx pages.
I am using flow player for my online tutorial site, which passes values dynamically. i.e. i am passing course id values, each id values having separate videos. Here is my code:
is it possible to put two different contentPlaceHolder from two different ASPX page in one MasterPage? Just like iFrame? if not what asp.net process/control can?
The base class includes the field 'WebUserControl1', but its type (common_WebUserControl) is not compatible with the type of control (ASP.common_webusercontrol_ascx)
I tried both, loading the usercontrol when needed and I also tried adding it directly into the aspx.
Nothing worked. With the second one (what's meant to be the easiest option) I tried with delegates and events (but can't access de usercontrol event from page) and tried with properties (I can access properties but they're always empty)
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)
i have user controls inherits from base user control like this:
[Code]....
How do i insert CustomerSendMail & UserSendMail into aspx page?
Note: The derived user controls having the same control layout as the base user control. Making copies of ascx page for CustomerSendMail & UserSendMail is not good idea, because if i modify the base's ascx page, the old CustomerSendMail & UserSendMail 's ascx page should be replace with the new one.
