TextBox Color Changes using Javascript

[stormcandi]

Hello,
I know this question has been asked everywhere but I cannot find a solution that will help me. I hope someone here has some ideas.

I have 9 TextBoxes in a Repeater Control. A user can edit dates in these textboxes. If the user changes the date, I want to dynamically change the color of the background of the textbox. When the data is saved I will set the textboxes back to it's original background(I can do this in the code-behind)
Right now I can get it to change but I have to do a postback in order to do it on the TextChanged Event of the TextBox. This page has 14 rows with 9 textboxes in each so postbacks are tedious to the user after 3 of them.
Can anyone help me accomplish this in Javascript?

Thanks in advance!

Use the text box's onchange event to change the color.

Use the text box's onchange event to change the color.

I have tried using the onTextChanged Event but no avail unless the page posts back which I do not want it to do.

This is in my code-behind:

  
 foreach (RepeaterItem item in rptrShots.Items)
 {
      TextBox txt1 = (TextBox)item.FindControl("txt1");
       txt1.Attributes["onTextChanged"] = "ChgColor('" + txt1.UniqueID + "');";
 }

This is in the mark-up:

<script language="javascript" type="text/javascript"> 
function ChgColor(sender)
{
    sender.style.backgroundColor = '#CC3300';
}
</script>

Can you not use normal JavaScript like, e.g.
[HTML]<input type="text" onchange="chgCo lor(this);">[/HTML]

No I get an error when I try to do it that way.
I get these types of errors:
Invalid expression term ')

This is what the markup for the textbox looks like:
[HTML]<asp:TextBox ID="txt1" runat="server" Text = '<%# Bind("Dose1") %>' MaxLength = "10" Width = "90%" OnTextChanged= "chgColor() ;"/>[/HTML]

Does anyone have any ideas on how to get this to work?

How does that turn out on the client-side?
