C# - Cannot Pass A Input From Text Box To A Query String And Then Keep The String In This Box?

May 28, 2010

I 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?

Make Encrypted String Same Length As Input String?

Nov 24, 2010

I have a 15 digit string to encrypt.

I have tried using .NET's various encryption functions but all my encrypted strings are at least 24, 28 or 32 in length.

I have heard of CipherMode.CTS with Padding = None that produces the same length output as the input length but I can't seem to get the same result. I have toyed with the block-size, key-size and salt size.

I don't mind adding a digit to my input string to make it 16 in length.

C# - Is Possible To Convert Input Control To Label

Mar 11, 2011

I am making a form that contains a lot of User Controls, each User Control is part of the form (contains TextBox, ComboBox etc). User will use the form to update their information. At end of submission, I need to display the original data and the data that the user have entered. I wonder if is possible that I can replace the input control (TextBox etc) to Label? So I can just simply use the same user control, then convert each of the input control to label to display the data... (I just don't really want to use readonly or disable) Note: I used different dataset to map each of the User Control data. What I was thinking to do is like to get the input control from Page.Controls:

aInputControl = new Label();

or...

Page.Controls.Remove(aInputControl);

Then somehow add new Label in same position in the page. But I have no idea how...can't think of anything except add another div to surround each of the control. I just wonder if it this is possible...

Seems like making new user control is not a good way for me. I will just try to somehow map each original data and new data into a new User control, and write them into page.
