Populate a Password Textbox from DB

Hello,

I have a query that populates several textboxes on my page.

I have a textbox called tboxPassword and it's type is set to password.

The the query runs, the Password box is left empty. I'm assuming this is some feature of the 'password' type assigned to the box. Is there anyway to overcome this? It's ok if the password still appears as ****, but I'd like it to be in the boxes.

Thanks!
Jason<input type="password" value="PASSWORDHERE" /
<asp:textbox TextMode="password" text="blahblahblah" runat="server" /
In either case, the password will appear as ****, but the underlying HTML (viewable through a simple "View Source") will show the password in plain text. In otherwords, you lose any and all password security by doing this and you shouldnot do it.
Actually, you cannot populate a password textbox from code. Even if you try to assign it a value, hoping it will appear as ****, it will not work.

As pickyh3d said, you shouldn't want to do this.

You can't do it anyway.
heh woops. I never tried it, so I just figured it would work... you could cheat and hard code it into an input tag, but you still shouldn't.

Populating a list box

Hi, I'm new to asp.net and would like to have a few questions answered regarding list box.

1) When one populates the list box with data from a field in a database table, where exactly are the data store?

2) How are the list items of the list box linked to the data that were used to populate the list box?

Suppose I have a list box named Singers Names which has the names of several famous singers and the corresponding images of these singers are stored as blobs in a field called Singers' Pics in a database table. According to a tutorial on reading and display blobs, if I wanted to display the images stored as blobs, I would have to populate the list box with the IDs of the images from the database. What I'd like to know are where are the IDs stored once the list box is populated with them and how are they related to the list items. Are IDs and the list items linked in any way at this point? I hope I am making sense please explain or point me to a good tutorial. Thanks for your help.

everything on client side is just PLAIN TEXT interpreted and rendered by client browser.

Are you are looking for this?

string cnStr = @."Persist Security Info=False;User ID=id;password=pass; Initial Catalog=AllTest;Data Source=datasource";string qry ="Select * from yourTable";SqlConnection con =new SqlConnection(cnStr);con.Open();DataSet ds =new DataSet();SqlDataAdapter da =new SqlDataAdapter(qry, con);da.Fill(ds);ListBox1.DataSource = ds;ListBox1.DataValueField ="SingerID"; //this will associate the ID to the items in the listboxListBox1.DataTextField ="Singer"; //this will display the names of singersListBox1.DataBind();

if you do a view source after running the project you will observe something as below:

<select size="4" name="ListBox1" onchange="javascript:setTimeout('__doPostBack(\'ListBox1\',\'\')', 0)" id="ListBox1">
<option value="1">singer 1</option>
<option value="2">singer 2</option>
<option value="3">singer 3</option>
<option value="4">singer 4</option>

</select>

What I'd like to know are where are the IDs stored once the list box is populated with them and how are they related to the list items.

You may need some guild on Data Access in ado.net.The id and the pictures are all stored in the database. We can get the correspondig picture by passing a specific in the sql-query clause (if we are using some control like a data grid, we can even list all the IDs with its corresponding pictures). Take a look at following links, they should help

Populating a text field and then getting its value

Hello All,
I am populating a text field dynamic in my code, and its a read-only
textbox control. It populates it perfectly fine. but when I get its value
back in code I get an empty string any clues as to how to get this sorted
please ?
Here is how I set the value of the control.
txtTitle.Text = feed.Channels[0].Title;
and get it later
String strString = txtTitle.Text;
Any clues please ?
Imran.Thats a strange one.
Working fine for me:
ASPX:
<asp:TextBox id="TextBox1" runat="server" ReadOnly="True"
OnClick="Button1_Click"></asp:TextBox>
<asp:Button id="Button1" runat="server" Text="Button"></asp:Button>
CS
void Page_Load(object sender, System.EventArgs e)
{
if(!Page.IsPostBack)
TextBox1.Text = "Hello";
}
void Button1_Click(object sender, System.EventArgs e)
{
Response.Write("Value: " + TextBox1.Text);
}
OUTPUT
Value: Hello
Try making a simple page like that and testing it

If I change the textbox property Readonly to false then it works perfectly
fine. I am using the latest Beta 2 release of .net framework.

Populating Drop Down Lists Based on Another DDL

Sounds like your repopulating the first dropdown in the load event. Try
wrapping the code that populates the first drop down in a
"IsPostBack==False" type check.

populates the second ddl but does not bind the grid.....though the
binding is not related to postback but to the selectedindexhanged(i shud
mention there is only value for the second ddl in my DB for first
ddl=australia)...is it related to the postback ...or is it because there
is only one value?
Thanks again for ur help.

My usual process for this is...

Put your grid-data-binding in a method/function/sub of its own. Call this
from the page load (wrapped in a isPostBack==False) then in each of your
drop down list events you can call the grid databind method.

BTW, do you really need a grid, they are very "heavy".
