I have one User Control ,which is added in to another user control.My First User control define propwerty to populate user control.It working fine if used in page.But now i have problem ,i have to add this control in to another user control. i have added that as we do to add user control ,but am not able to pass the value to that first control from my page.
I need to create a user control which will be loaded according to the selected value of a dropdownlist. The Dropdownlist is not the part of Control. I want to pass the value of selected value of dropdonwlist to my user control and the user control will load according to the Value. For not postback it work fine. But when the page is postback, that is when i select a item form dorpdownlist, the user control is not loaded.
i am trying to make a pop-up messsage box, using popupControlExtender. Such extender will be inside a web user control but the target control will be outside the user control instead. Could anyone tell me how i can do it ?
I am using the below example code and have a problem where I can't pass the Request.RawUrl value into an object that extends the Control object (class Test below).When I use the line:
the string value "<%= Request.RawUrl %>" is passed to the Target property.I need to get the value of Request.RawUrl passed to the Target Property of my Test control object. Does anyone have any ideas where I am going wrong?Control:
Basically I want to call a user control from a master page. However, I need to pass an object (a List of objects to be more specific), to the user control. I'm generating the list of objects in the Page_Load of the master page. Here's the line in my master page that calls the user control.
This user control has a parameter called CalendarItems that accepts the list of items. However, if I try to set this inside of the Page_Load method, my control executes before the Page_Load and throws an exception saying CalendarItems is null. Is there any way around this?
EDIT: I have a drop down list on this page that determines what the list of CalendarItems is so when I populate the CalendarItems list I need to be able to read the selected value from the drop down list.
In Asp.net Web forms why must a user control be partial? I tried to remove the partial keyword and it says: Missing partial modifier on declaration of type 'test'; another partial declaration of this type exists Where is the other declaration?I am trying to pass a generic type with the user control how can I do that? I can't unless I change the other declaration too. I couldn't find it so I removed the partial keyword.Note: you do have 3 files if your making WebApplication but if your making website you only get 2 files? UserControl.ascx UserControl.ascx.cs so in website where is the other declaration?the reason i want generic is because im making a Grid User Control so i want to pass the type the datasource is going to have.
I don't think I understand fully how ASP.NET does inheritance of controls.I have a user control, ucBase, which has an asp.net label in the ascx file. Code behind references the label and it works fine during run time if the control is not a parent for another user parent.
If I have another user control, ucChild, inheriting from ucBase, the label in ucBase's code is always null. ucChild has no controls in its ascx fileThe server controls (like the label) needs to be declared in the ascx file and not created programmatically.What needs to be done for ucBase to see its own controls when it's a parent user control?
I've got a web site that has a master page and that master page (mpMaster that has a user control ucControl1) which has a sub user control (ucControl2), this user control has a property which accepts a value. Now, I have a page that uses the master page and on this page I have another user control (ucPageControl), I need to find a way of setting the value in ucControl2 from ucPageControl. Is this possible at all?

I've to Web User Control. I want my first usercontrol redirects the page to the page which second userscontrol is in. I think this is not a good idea to put the address of second page in the user control. what's the best idea to acquire address of the page of second usercontrol?
All I would like to be able to do is include one user control within another! Is this possible? I have spent the last hour searching the internet and it seems that I can't find a single thing.
In classic ASP it would be something like: <!--#include file="EditProject.ascx"-->
I tried this but no luck!
Parser Error Message:
There can be only one 'control' directive.

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.
This is placed in the sqldatasource selecting sub. It works well and loads up data from the database based on the @UserId parameter.
I load up the detailsview and it only loads up data from the DB based on the currently logged in user, however i want them to be able to insert some data too.
Anyone know how i can achieve this when they select insert? For starters i having endless parameter problems but i am sure i can sort that out. what i really need is someone to tell me how i can pass the UserId into the USERID text when the details view mode changes to "insert"
I know there is a "mode changed" event, should i be using that?
I want to use a couple of instances of the same control on a page. The user control is intended to display a list of records in a repeater. The aim is that the second control will show a list excluding the IDs in the first control The control has a number of public properties, including IDsInThisList, and IDstoExclude. The query will exclude the IDs in the second property.
What I would like to do is get the record IDs from the first instance of the control (IDsInThisList), and pass them to the second contro as the IDsToExclude.
I have a test page where I am setting the properties of the controls in code. As you might guess, it's not working! The first control displays the top 3 items, as desired, but the second display the records 1-7, rather than records 4-10 because it is not receiving the IDstoExclude from the first control When I response write the IDstoExclude from the first control in my testpage, the string is empty. (if I do it from within the control, it shows the IDs)
How can I get the controls to fire in order and pass values to each other?
Screen grab of test page + uc and test page code attached
i would like to ask about how can i open user control page when i click a button on parent page, also, can i call parent's method from user control page and then refresh parent page?
I'm developing an ASP.NET application with C# and Ajax.I have a page that holds user controls loaded dynamically. I need to pass some data (integer values and some strings) to the user control that has been loaded dynamically.Now I use Session to pass these values, but I think I can use another way; something like VIEWSTATE or hidden input.What do you recommend me?The fact that I load the controls dynamically is important because controls are loaded on every postback, and I can't store any value on controls.
