Web Forms :: Passing Values From Parent Page To User Control And Maintaining The Values Added

Mar 18, 2011

I wanted to know if we can pass values from Parent page (in this case from Default.aspx page) to the user control and maintain those values on subsequent "Add/Load" of user control.

So in short, if I click the "Add" button it loads my "webusercontrol" and also I am able to pass my default.aspx dropdownlist value to this dynamically loaded user control and assign it to a "Label or Textbox" which resides in my "webusercontrol", now the problem is that the value doesn't persists! What I meant is , when I click "Add" button again the "webusercontrol" gets loaded again perfectly but now all my "Label's" in webusercontrol has the new selected value from the default.aspx dropdownlist.

So say for instance I have a Dropdownlist in Default.aspx page with Values "Apple, BlackBerry, Nokia" and initial value to be passed is "Apple", I click the "Add" button, now my "Label" inside webusercontrol has the value "Apple", perfect! Next when I click "Add" button again and select a different value to be passed this time say "BlackBerry" now I have 2 webusercontrol loaded on the page, so that means I have 2 "Labels" with different ID's, but now my first Label initially had the value "Apple" because that's what I had passed and now when I passed the value "Blackberry" both the labels of my webusercontrol has the value "BlackBerry" instead of one being "Apple" and another "BlackBerry"

Is there a way to resolve this issue? may be Dictionary List?

C# - Passing Values Across Pages?

Apr 7, 2010

i need to pass a long list of Ids from one page to another, i was thinking of using querystring but taking in consideration that the number of ids to be passed may reach 300 i think is not a good idea.an option from my understanding may be the use of session, this seems to me an optimal solution in my case but on the other hand I can certainly clear the session when the user performs a certain action and the list of ids is not longer needed, but if the user leaves the page without performing any action i want to clear the session, how can i do it?f multiple users are using the same functionality do i need the session's items to be confused or the session is for a single user?

C# - MVC AuthorizeAttribute Passing Values To ActionMethod?

May 14, 2010

I'm only a newcomer to ASP.NET MVC and am not sure how to achieve a certain task the "right way".

Essentially, I store the logged in userId in HttpContext.User.Identity and have written an EnhancedAuthorizeAttribute to perform some custom authorization.

In the overriden OnAuthorization method, my domain model hits the database to ensure the current user id can access the passed in routeValue "BatchCode". The prototype is:

ReviewGroup GetReviewGroupFromBatchCode(string batchCode);

It will return null if the user can't access the ReviewGroup and the OnAuthorization then denies access.

Now, I know the decorated action method will only get executed if OnAuthorization passes, but I don't want to hit the database a second time to get the ReviewGroup again.

I am thinking of storing the ReviewGroup in HttpContext.Items["reviewGroup"] and accessing this from the controller at the moment.

C# - Passing Two Values Through CommandArgument And Splitting It?

Dec 7, 2010

I'm using the commandArgument property of the LinkButton ( Which is wrapped inside a repeater ) to pass two values -as one string- to a second repeater then I try to split them into two values, So I could use them as parameters in my ADO.NET Code (SqlCommand Parameters)....after testing my queries don't return any results but If I passed fixed values for the parameter or change the source of the parameter (just for test from a textbox or querystring or something) I get my results, so I think the problem is in splitting.

I Conduct some arugment values from the ArgumentCommand property of the LinkButton -which is wrapped inside a repeater:

<asp:LinkButton id="sort_lnkbtn" Text='<%# Eval("value")%>'
CommandArgument='<%#string.Format("{0}|{1}",Eval("arrange_by_id"),Eval("value"))%>' runat="server">

Then I receive these values and cut them into two pieces of information:

string sortByAndArrangeBy = (e.CommandArgument).ToString();
char[] separator = { '|' };
string[] sortByAndArrangeByArray = sortByAndArrangeBy.Split(separator);

Now the ado.net code uses this values as a

using (SqlConnection cn1 = new SqlConnection(ConfigurationManager.ConnectionStrings["testConnectionString"].ConnectionString))
using (SqlCommand cm1 = new SqlCommand("SELECT [name] FROM brands WHERE (name like @SearchString + '%' )", cn1))
cm1.Parameters.Add("@SearchString", System.Data.SqlDbType.Char);
cm1.Parameters["@SearchString"].Value = sortByAndArrangeByArray[1];
using (SqlDataReader dr1 = cm1.ExecuteReader())
List_rpt.DataSource = dr1;

VS 2005 Passing Textbox Values To SQL (not Null)?

May 7, 2010

SELECT one, two, three, four FROM tblFixedLine_onenet_callLog WHERE (one LIKE '%' + ISNULL(@one,'') + '%') AND (two LIKE '%' + ISNULL(@two, '') + '%') AND (three LIKE '%' + ISNULL(@three, '') + '%') AND (four LIKE '%' + ISNULL(@four, '') + '%') ORDER BY one, two, three, four
@one, @two, @three and @four are textboxes on my ASP.NET page all of which by default have no value(therefore i assumed NULL).If i test the SQL in the VS2005 SQL Configuration (and put the values in manually) it works but the ASP page returns no results... i assume therefore the Textbox value is "" not Null.

Asp - ObjectDataSource UpdateMethod Passing Updated Values

Mar 24, 2010

I've got a gridview connected to an objectdatasource which is bound to some custom objects in my code (code is below). The problem I'm having is that the value passed into my update method is the old value, not the new value. Thoughts?

End Sub
End Class

Public Class Users
Private sName As String
Private sPassword As String
Public Sub New()
End Sub
Public Sub New(ByVal nm As String, ByVal pass As String)
Name = nm
Password = pass
End Sub
Public Property Name() As String
Return sName
End Get
Set(ByVal value As String)
sName = value
End Set
End Property
Public Property Password() As String
Return sPassword
End Get
Set(ByVal value As String)
sPassword = value
End Set
End Property
End Class

Public Class UserData
Dim auth As AuthenticationSection
