I need to pass a dollar amount from one webpageto another webpage without letting the user modify the values when the values are passed between these pages. ie Page 1 (entry page) to Page 2 (confirmation page)
View 2 RepliesI 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?
I have a web page that contains a GridView which the user is allowed to "Edit", "Delete" and "Select" rows. What I'm trying to accomplish is when a user clicks on "Edit", they are redirected to another web page that contains a DetailsView of the record they selected from the GridView (previous page). How do I make the association?

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?

Can someone please explain how I get values in to @start and @end? I have searched and seen that it might have something to do with overriding the Fill function in the DataSet code behind file. Please let me know.

View 9 RepliesI'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.
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:
<ItemTemplate>
<asp:LinkButton id="sort_lnkbtn" Text='<%# Eval("value")%>'
CommandArgument='<%#string.Format("{0}|{1}",Eval("arrange_by_id"),Eval("value"))%>' runat="server">
</asp:LinkButton>
</ItemTemplate>
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];
cn1.Open();
using (SqlDataReader dr1 = cm1.ExecuteReader())
{
List_rpt.DataSource = dr1;
List_rpt.DataBind();
}
}
}
I usually use STATIC implementation when developing Desktop Application and I just got my head bumped on the wall when I use STATIC in ASP.NET (not a good idea)I think I saw some feedback here before that you can use INTERFACE for passing values between Classes and Pages without using Session.here's my sample code
public interface ISessionManager
{
SessionStates sesState { get; set; }[code]....
Code:
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.
