I am using an iframe in my page and the src value of iframe is changed at runtime.because I want to authenticate the page which is being called.
for e.g.
src value is "~/Login/Login.aspx" in design. and at runtime it changes to "~/Login/Login.aspx?un=abc&pswd=123".
now, I don't want to show this query string when a user clicks View Page Source in the browser.
it should show only "~/Login/Login.aspx".
how can we hide the query string parameters in the URL in asp.net . but i am not interested to use url rewriting.

View 1 RepliesI have a drop down box that is in the edit template of a formview. I want to be able to add a parrameter to the querystring when the drop down selected index is changed.
I tried
Request.QueryString.Add("tabindex", (sender as WebControl).TabIndex.ToString());
But I got an exception saying the collection is readonly.
Here is my markup
<icms_ref:ReferenceDropDownList ReferenceDataManagerProviderName="ROCSQLReferenceDataProvider"
ID="ddlEnquirerHearType" TabIndex="2" runat="server" ReferenceSetName="EnquiryHearType"
AutoPostBack="true" OnSelectedIndexChanged="EnquirerHearType_SelectedIndexChanged"
DataTextField="ShortName" DataValueField="ReferenceId" />
and here is my code behind.
protected void EnquirerHearType_SelectedIndexChanged(object sender, EventArgs e)
{
var pnlEnquiryHearTypeOther = fvEnquiryInformation.FindControl("pnlEnquiryHearTypeOther") as Panel;
pnlEnquiryHearTypeOther.Visible = DdlEnquirerHearType.SelectedValue == ((int)EnquiryHearType.Other).ToString();
ResetTextBox("txtEnquiryHearTypeOther", fvEnquiryInformation);
Request.QueryString.Add("tabindex", (sender as WebControl).TabIndex.ToString());
}
Example:
[URL]
I added the iis tag because I am guessing it also depends on what server technology you use?

View 7 RepliesI have a simple ASP.net page:
<form id="form1" runat="server">
<p><asp:TextBox id="input_box" runat="server"></asp:TextBox>
<asp:Button Text="OK" runat="server" OnClick="run" /></p>
</form>
I want to send input from input_box to a query string, and then keep this input in the input_box when the page reloads.
That's the code behind page:
protected void Page_Load(object sender, EventArgs e)
{
input_box.Text = Request.QueryString["input"];
}
protected void run(object sender, EventArgs e)
{
string url = string.Format("?input={0}", input_box.Text);
Response.Redirect(Request.Url.AbsolutePath + url);
}
Problem is that when query string is not empty, string from input_box cannot be passed to query string. How to correct it?
We are sending an HTML encoded string in the Query string. It was working fine on IIS 6 (windows 2003). We have recently moved the website to Windows 2008 (IIS 7.x). Since the move any Query String that contains "+" sign i.e., "%2b" gives error on the server "404 -File or directory not found."
View 2 RepliesI am trying to use a variable from the code-behind page in a sqlDataSource WHERE statement. I am using Membership.GetUser().ProviderUserKey to obtain the UserId of the logged in user and I would like to only show record that have this UserId as a foreign key. How can I write the SQL for this?
Here is what I have so far:
SQL Query:
SelectCommand="SELECT [UserID], [CarID], [Make], [Model], [Year] FROM [Vehicle]"
Code-Behind
String user2 = ((Guid)Membership.GetUser().ProviderUserKey).ToString();
And I want to add WHERE UserID = user2 to the SQL Query.
I wanted to create a URL like http://localhost/menu.aspx/?id so that on typing this, it displays all the id's in the database. for eg:134
123
543
234
may be the id's which should be displayed after fetching from the database. However, it should be displayed as it it is without any control or without arranging in any gird etc. How can that be done?
I'm concatenating a string in codebehind to use in a sql select statement.
in aspx
<asp:Label ID="LabelHidden" runat="server" Visible="False"></asp:Label>
SelectCommand="SELECT * FROM [Data] WHERE [ActivityName] IN (@ActivityName) AND ([ID] = @ID)"
<SelectParameters>
<asp:ControlParameter ControlID="DropDownList_Employees" Name="ID"
PropertyName="SelectedValue" Type="Int32" />
<asp:ControlParameter ControlID="LabelHidden" Name="ActivityName"
Type="String" />
</SelectParameters>
in codebehind
foreach (ListItem li in ListBox_Activities.Items)
{
if (li.Selected)
{
queryBuilder += li + "', ";
}
queryBuilder = queryBuilder.Substring(0, queryBuilder.Length - 1);
LabelHidden.Text = queryBuilder;
When i run the code it comes up blank. I did a query trace and it seems to be running as
exec sp_executesql N'SELECT * FROM [Data] WHERE [ActivityName] IN (@ActivityName) AND ([ID] = @ID)',N'@EmployeeID int,@ActivityName nvarchar(50)',@EmployeeID=4,@ActivityName=N'Production Technical Support'', Tools Development'','
with exta "'s
How can i format the queryBuilder string correctly in my code?
We're migrating one of our sites to ASP.Net. We do not want to use integrated security, which uses the windows account to connect to sql server (not going to get into why, its just out of the question). We created a username and password to connect to SQL Server, and would like to use that username and password, however, we also do not want other developers to see this information (easily read from the web.config).... I know it can be encrypted, but it can just as easily be decrypted by the developers - plus encryption has a performance hit.
View 5 RepliesI am working with MVC2 and one of the view model's properties is IDictionary<Int32, String>.
This is not to be changed on the view. But when the form is posted back I would like to still get those values.
Can Html.Hidden store this property values?
How should I do this so the model still gets the IDictionary<Int32, String> values on the POST action?
I am writing a content management system using JQuery.ajax & C#. The JQuery calls an httpHandler and POSTS the html from an html editor JQuery plugin.
I get an error in the handler about unsafe content (html basically) but I dont want turn off validation for the whole page, just the handler (the handler is part of a web control not the page).
So, is it possible to turn the validation off just for one handler? Or do I need to encode the html on the client?
In the end I went for the encoding on the client at Javascript/JQuery HTML Encoding
Is it safe to send a POST to a web method with a JSON string containing a clear text version of a password for authentication?Who could sniff that password on the way from client to web method? I saw some posts a while ago on "salting" a password - is that something you do in JS on the client side and then "unsalt" on the server?

I am looking for a solution to a Java Script question. My question is this, I have a gridview, and in this gridview I have a column, which I use as a flag. The gridview itself is dynamically added to a user control and then to the page. What I would like to do is to use Java Script to hide this column, but I do not know how to do this. Unfortunately, I cannot use code behind, because of the gridview being dynamically added. Also, I have one further question, I already have some Java Script code that can hide some of the rows based upon the values in my column when a button is clicked. What I want to do is when the page is loaded for the first time, to hide some of these rows, and to use the button in reverse to reveal them again. How do I achieve this?
