Cannot change value of pre-populated textbox in web part

I have a user control inside a web part. I am pre-populating a textbox in the Page_Load event in the code behind of the user control. The value I am pre-populating is a value the user previously entered. The value is pulled from a sharepoint list. We want the user to be able to change this value if they need to. No matter how many times I change the value in this field, it keeps the pre-populated value. It will not save the new value back to the list. The list item is being saved, but only with the pre-populated value. If I remove the line of code that pre-populates the textbox from the page_load event, then I can change the field without issue. Since I have little experience with using user controls, I am not sure what I am doing wrong. Should I be pre-populating this field in another event?

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

// aspx
<asp:TextBox runat="server" ID="txtOld" TextMode="MultiLine" Columns="70" Rows="30" Width="425px" />
<asp:TextBox runat="server" ID="txtNew" TextMode="MultiLine" Columns="70" Rows="30" Width="425px" />

In Textbox, type in one letter and show words starting with that letter


Hi everyone,

I think this is a little tricky problem, but I need to solve it somehow. 

I have a texbox in my asp.net page.

I want to show all names when a user types in a letter in that textbox, whatever names starting with that letter.

the names are from a list generated by other function, pulled out from active directory.

So for example:

User types in "a" in a textbox then automactically names "aron" "asron" "amanda" in the list shows, and user can select one of those names.

How can I do this?

Thank you for advance :)
