I have a standard Login form
<asp:Login ID="lgnExcel" DestinationPageUrl="login/data.aspx" OnAuthenticate="Login1_Authenticate" runat="server">
Is it possible to attach the Username as a query string with the DestinationPageUrl or reference the value in the code behind. I've tried lgnExcel.UserName.ToString()
I am using Html.ActionLink<Controller>(p => p.Action(), "action link") syntax for generating urls in views.In one of the cases I need to attach the existing query string from the url. How would you recommend doing this?
View 2 RepliesI have an ASP.NET VB website in which I am using the Membership functionality to authenticate users. I am doing this through the Login control on the HTML page. I have working that it will authenticate the user and then opens a welcome screen in which I have a button they can push to open a Reports.aspx page. On that page I have a dropdown box that is being populated from a datasource connection query to my SQL Server database table. It is a hard coded query but want it to query the table off the username text value that the user provided on the login (i.e. select <something> from inventory where username = <username>). I have not behind code but only HTML at this point. Here it is ...
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Login.aspx.vb" Inherits="Login" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

My Login.aspx form in Visual Studio 2013 just seems to be 'static' after I enter the correct username and password. I don't get any errors. My Login.aspx.vb code looks like this:
Code:
Imports Microsoft.AspNet.Identity
Imports Microsoft.AspNet.Identity.EntityFramework
Imports Microsoft.AspNet.Identity.Owin
Imports System.Linq
Imports System.Web
[Code] ....
Don't I need a file name/URL to direct the user to after he has successfully logged-on? How would I script that? Finally, I only have one Web.config file (associated with Register.aspx) and that looks like this:
Code:
<?xml version="1.0"?>
<configuration>
<system.web>
<customErrors mode="Off"/>
[Code] ....
I don't need another Web.config file for Login.aspx, do I?

how to pass through a query string parameter of an assignment id and then checking and validating this as a number and displaying the information returned on screen. At present I have code which displays the information on screen but this is by entering in the assignment id and by triggering the button click event, I've shown the code for this below:
.aspx
<div>
<b>Current Assignment</b>
<br />
<asp:TextBox runat="server" ID="txtAssignmentID"></asp:TextBox>
<asp:Button runat="server" Text="Get Assignment" />
<br />
<b>Date Started:</b> <asp:Label runat="server" ID="lblAssignmentStart"></asp:Label>
<br />
<b>Status:</b> <asp:Label runat="server"></asp:Label>
<br />
<b>Current Achievement Level:</b> <asp:Label runat="server" ID="lblAssignmentLevel"></asp:Label>
<br />
<b>Date Last Calculated:</b> <asp:Label runat="server" ID="lblAssignmentCalcDate"></asp:Label>
<br />
</div>
.cs
protected void cmdGetAssignment_Click(object sender, EventArgs e)
{
//Check the assignmentID is an integer
int AssignmentID = 0;
try
{
AssignmentID = TypeConv.CInt(txtAssignmentID.Text);
}
catch
{
}
if (AssignmenttID > 0)
{
//Create new TCAAssignment object by passing the ID
TCA Assignment Current Assignment = abc.TCA Assignment (AssignmentID);
lblAssignmentStart.Text = Current Assignment.dDateCreated.ToString();
lblAssignmentStatus.Text = CurrentAssignment.rTCAAssignmentStatus.dDescription;
if (!CurrentAssignment.dTCAAchievementLevel.IsNull)
{
lblAssignmentLevel.Text = CurrentAssignment.rTCAAchievementLevel.dDescription;
}
lblAssignmentCalcDate.Text = CurrentAssignment.dAchievementDate.ToString();
}
}
Code example passing through a query string parameter of an assignment id would be great.
I have a dropdown list that won't populate data values from database using sql datasource. When i use the code behind, i was able to populate the data to the dropdown list. I dont know how to pass the Query String Parameter using code behind since i am new in asp.net. This is the code behind:
Imports System.Data.SqlClient
Partial Class PhotoAlbum
Inherits System.Web.UI.Page
Dim oConn As New SqlConnection("Data Source=.SQLEXPRESS;" & _
"AttachDbFilename=|DataDirectory|ASPNETDB.MDF;" & _
"Integrated Security=True;User Instance=True")
Dim oCmd As New SqlCommand()
Dim oDR As SqlDataReader
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
oConn.Open()
oCmd.CommandText = "SELECT [CategoryID], [Name] FROM Categories ORDER BY [Name]"
oCmd.Connection = oConn
oDR = oCmd.ExecuteReader()
Me.categories.DataSource = oDR
Me.categories.DataTextField = "Name"
Me.categories.DataValueField = "CategoryID"
Me.categories.DataBind()
oDR.Close()
oConn.Close()
End Sub
End Class
I will like to include the following information from sqlDatasource to the codebehind:
SelectCommand="SELECT [CategoryID], [Name] FROM [Categories] WHERE ([UserId] = @UserId) ORDER BY [Name]">
<SelectParameters>
<asp:QueryStringParameter Name="UserId" QueryStringField="ID"/>
As you can see from the code behind, i was able to add :
"SELECT [CategoryID], [Name] FROM Categories ORDER BY [Name]".
But i will like to add all of this:
SelectCommand="SELECT [CategoryID], [Name] FROM [Categories] WHERE ([UserId] = @UserId) ORDER BY [Name]">
<SelectParameters>

View 3 RepliesI have a stored procedure that is close to working. It takes the values of a details view puts them into the respective table 'entity' then should also put the @@identity into 'entloan' and should put the LoanID which is in the query string of the page the detials view is loaded on, into the LoanID field of entLoan as well.

I'm having troubles passing a parameter to a handler in it's query string. I have a gridview with an image column, this column is defined as a TemplateField, as:
<asp:TemplateField
HeaderText="Image">
<ItemTemplate>
<asp:Image
ID="Image1"
runat="server" ImageUrl='~/ImageHandler.ashx?ID=<%# Eval("EmployeeID")%>'
/>
</ItemTemplate>
</asp:TemplateField>
As you can see, the ImageUrl is a call to a handler that receives the EmployeeID in the QueryString, under the name ID. When I run it, the ImageHandler method receives the following query string "ID=<%" instead of "ID=<the result of Eval("EmployeeID")>", and of course, it throws a FormatException when using it as an int to get the EmployeeID. (If I type ImageUrl="~/ImageHandler.ashx?ID=<%# Eval("EmployeeID")%>" (using " instead of ') the compiler returns the error incorrect server tag) The complete markup is:
<asp:SqlDataSource
ID="SqlDataSource1"
runat="server"
ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"
SelectCommand="SELECT [EmployeeID], [LastName], [FirstName], [Photo] FROM [Employees]">
</asp:SqlDataSource>
<asp:GridView
ID="GridView1"
runat="server" DataSourceID="SqlDataSource1"
AutoGenerateColumns="False">
<Columns>
<asp:BoundField
DataField="EmployeeID"
HeaderText="ID" SortExpression="EmployeeID"
/>
<asp:BoundField
DataField="FirstName"
HeaderText="FirstName"
SortExpression="FirstName"
/>
<asp:BoundField
DataField="LastName"
HeaderText="LastName" SortExpression="LastName"
/>
<asp:TemplateField
HeaderText="Image">
<ItemTemplate>
<asp:Image
ID="Image1"
runat="server" ImageUrl='~/ImageHandler.ashx?ID=<%# Eval("EmployeeID")%>'

Could anybody tell me what am I missing here?

In the original site, master page has code-behind to check a query string parameter value. Depending on this value, code-behind dynamically modify some CSS property to hide / display master page elements.
As MVC2 has no code-behind because we are supposed to perform everything in the controllers, how should I proceed in this case ?
I see this : [URL]
It partially answers my needs but the query string processing is common to all pages. How can I move this processing in a common code section ?
I've a page in ASP.NET, whose appearance can change based upon a given parameter(say query string),
How can I achieve this in ASP.NET, Master pages concept won't work here, as even the contents of the page and positioning of the controls on the page can change based upon the parameter.
One solution I can think of is using XSLT, but is there any other solution I can use to solve this problem? Is there any concept of templates I can use here?
How do you use the http POST method with a Grid View on another page. I am trying to use the POST method to send the ID from the selected row of a Grid View, I am using a link button set to fire the select command and it has the Post Back URL set, from one page and then retrieve the ID value on another page using an Object Data Source. Also, under the Defining Parameters, I am setting the ID parameter to Form Parameter Source and have entered the Grid Views name in the Form Field.
View 4 RepliesI am using IIS 7 and have URL rewrite turned on for a friendly URL.
The problem is that in side that pages repeater (right under the captcha) when I click on the images in there the page redirects to /null/ which then throws a 404 error. I have turned off url rewrite and removed all rules and that didnt solve the problem so I dont think its related to that.
I have also noticed that in my master page if I use <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
then the client side ajax fails to load, sys becomes undefined and that may be the problem here

I am trying to display a local .html file in a web page. The file uses javascript to display some information about my phone. In the executable, I am retrieving two values out of the registry. I would like to pass these values in a query string (I think that is the correct terminology). Something like file://\Program Files\TestTest.html?type=newtype. I have attempted this with using webbrowser.navigate, but that is giving an unhandled exception when it tries to pass the URI string. Obviously, I have no experience with this and am using the wrong method. There has to be a simple way to open a new webpage in a form and pass it this type of string.
how to implement such a function? I have been attempting to implement this with Visual C# using the .net CF for Windows Mobile.
In my Application_BeginRequest I have code that gets query string value ?c=FR or ?c=US and store it in cookies.Based on query string value I have either US or FR,locale is selected from locale table.If ?c=FR then locale will be fr-FR and if it is US then locale will be en-US.My code is below.
void Application_BeginRequest(object sender, EventArgs e)
{
LocalizationInfo loc = GetLocalizationInfo();
if (Request.Cookies["Localization"] == null)
Response.Cookies.Add(new HttpCookie("Localization"));
Response.Cookies["Localization"]["Country"] = loc.Country;
CultureInfo objCI = new CultureInfo(loc.Locale);
Thread.CurrentThread.CurrentCulture = objCI;
Thread.CurrentThread.CurrentUICulture = objCI;
}
public static LocalizationInfo GetLocalizationInfo()
{
string countryCode = "";
string sLocale = "";
if (HttpContext.Current.Response.Cookies["Localization"]["Country"] != null)
countryCode = HttpContext.Current.Response.Cookies["Localization"]["Country"];
if (!string.IsNullOrEmpty(HttpContext.Current.Request.QueryString["c"]))
countryCode = HttpContext.Current.Request.QueryString["c"];
if (countryCode == "")
countryCode = "US";
sLocale = HertzRent2Buy.DataProvider.ListData.GetLocale(countryCode);
LocalizationInfo ret = new LocalizationInfo();
ret.Country = countryCode;
ret.Locale = sLocale;
return ret;
}
public struct LocalizationInfo
{
public string Country;
public string Locale;
}
Now when I run the project and in query string I set [URL] then for the very first page(home page itself) it shows me French translation,but on subsequent page,that query string parameter ?c=FR is lost and hence it shows be English translation not French translation since it does not pickup French resx file.If I manually append ?c=FR in subsequent page then it shows the French translation.Is there is way how I can make that query stringparameter available in all pages.Structure is there to hold Country and locale variables. In all pages I am calling GetLocalizationInfo() method as follow
LocalizationInfo info = some.DataProvider.Globalization.GetLocalizationInfo();
And I create instance info to pass locale and country as parameter. GetProductDetails(id,info.Country,info.locale). why my query string parameters get lost on subsequent pages.
