Web Forms :: Pass Values Between User Controls On Two Different Aspx Pages?

Sep 12, 2010

I have 2 user controls that is hosted by 2 different aspx pages.


srcpage.aspx --> hosts the --> sourceusercontrol.ascx
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.

Forms Data Controls :: Pass User Id To A Boundfield On Insert?

Feb 15, 2010

I have the following code:


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?

Web Forms :: Pass Data From A Page To ASCX User Controls Loaded Dynamically?

Feb 7, 2010

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.

Forms Data Controls :: Update GridView - Pass Current User To Stored Procedure?

Feb 26, 2010

I have a page, let's called that Parameter page, displaying data from a database table using GridView. (The database is a SQL database.) I allow editing of data in GridView. The GridView uses stored procedure to retrieve data and to update data. In my project, users need to log in before using my asp.net project. So at every page, I know who the current user is by using HttpContext.Current.User.Identity.Name. Now as requirement changes, I need to record who has changed what (row) in the Parameter page. The information is to be written to a new table - audit log. Therefore I do not expect to change the Parameter table structure.

I have modified the stored procedure retrieving data. It returns one more column - an empty column with name currentUser. So GridView will create one more column. After data bound, I have the GridView_DataBound() to popluate that column using HttpContext.Current.User.Identity.Name.

I debug it in Visual Studio and am able to see the name of current log in user as the last column in GridView. I change the update stored procedure to take in one more parameter. That parameter, currentUser, takes default value. The default value is an empty string. So if UI part fails to send in the current user name to stored procedure, it just write the empty string as the user name. I change the <asp:SqlDataSource>. I add a <asp:Parameter> for currentUser.


I debug in Visual Studio. However when I save the change, the SQL profiler shows UI sends in @currentUser as NULL. Why?

Web Forms :: Pass Data From User Controls To Their Parent Forms?

Jun 10, 2010

I'm building a web page that is going to make extensive use of User Controls. Using "LoadControl" it will have one of about 20 different User Controls loaded at any one time. Each User Control is somewhat different, gathering different sorts of data.

I've already built the mechanism to load the User Control and pass strongly typed data to it. But now I'm tackling the part of returning the user data to the Parent Form. I can think of several possible approaches to take but wanted to reach out to the community to learn what the best practice for doing this is.

User Controls :: How To Pass Value From UserControl (ASCX) To Page (ASPX)

Jan 19, 2014

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?

There is part of my code in .ascx:

public string showOnaspx { get; set; }
protected void GridView1_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
GridViewRow row = GridView1.Rows[e.NewSelectedIndex];
showOnaspx = row.Cells[1].Text;
e.Cancel = true;
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
GridViewRow row = GridView1.SelectedRow; 
//row[i].Attributes.Add("onclick", "$('#ContentIndex_sometextbox).val(" + row[i].Cells[1].Text// + "); $('#Close').click();");

I also tried with jqeury (comment in selectedindexchanged function), but it does not work well, because user have to click SELECT two times to effect.

C# - Can't Pass A Variable To A User Control?

Jun 17, 2010

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:

<Test1:Test runat="server" ID="testControl" Target="<%# Request.RawUrl %>"></Test1:Test>

I find that the Target property is never called.If I use this line instead:

<Test1:Test runat="server" ID="testControl" Target="<%# Request.RawUrl %> test"></Test1:Test>

the string value "<%# Request.RawUrl %> test" is passed to the Target property.f I use this line as explained in many posts online:

<Test1:Test runat="server" ID="testControl" Target="<%= Request.RawUrl %>"></Test1:Test>

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:

namespace Testing
public class Test : Control

How To Pass 'user' Object From Aspx To Silverlight 4

Dec 28, 2010

First, we are constrained to using an existing web framework that handles authentication and authorization. The web project uses forms authentication and writes to an encrypted cookie. The user information is exposed to the aspx pages as a property:


This has several properties including the userId and role list.

I've looked at using initParams, but haven't been very successful there (edit: I couldn't do it dynamically originally). I've created a simple POCO entity with a [Key] attribute, but I need to at least be able to pass the userId from the aspx page to the imbedded silverlight.

What is the easiest way to pass a dynamic object from aspx to silverlight 4?


Then used Slugster's example to use the values on the Silverlight side.

Warning: Passing user information via init params exposes the info as plain text to the user viewing the page (they just have to view the source). We ended up using an authentication domain service and using the same user object as the aspx

Pass Parameters To User Control At Page_Load?

Jun 21, 2010

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.

<cu:Eventlisting1 runat="server" id="eventListing1"></cu:Eventlisting1>

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.

C# -pass A Generic Type With The User Control?

Aug 19, 2010

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?
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.

Security :: Pass User Between Two Different Apps/websites/projects?

Feb 3, 2010

We have two different websites that run two seperate web sites (a backend and a front end) for our peice of software. The way we do our authentication is to put the user id into the session when the user logs in, all the pages on the site inherit from one base page if this base page cannot find this value in session it kicks the user out to the login screen.

What we want to be able to do is have a link on the front end after the user logs in and when they click on it it takes them(redirects them) to the back end. However I cannot think about how to do this in a secure and sensible way. I did think of putting the users username and password dynamically generated into the hyperlink that takes them from the front end to the back end. Would this be advisable. It will be clear text but then again we done use ssl in any case just plain forms authentication. I mean I will hash the values anyway but still be sending them. I suppose is there a way to share a session across two app domain without too much dificulty?
