Cannot change value of pre-populated textbox in web part

Posted By:      Posted Date: August 31, 2010    Points: 0   Category :SharePoint
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?

Textbox text populated by Session Variable wont update into SQL with new text


Hi everyone, I have what I think is a weird issue. I send text from one page to another via Session Variable. When page 2 loads, the text box has the session text set, but if the user changes the text and clicks the button, the SQL database is update with the original session text. If I remove the redirect from the page 2 button_Click method, then, the page refreshes with the textbox reverting to the session text and thr SQLDataSource has the session text added to it.

Why would the button click cause the textbox refresh with the text from the pageLoad before updating the data source?

Change part of a page without full postback


I have a page with two columns. Initially, the left column will contain a list of links that are article titles. Clicking on one of the links will display the text of the article in the right column, keeping the list of titles in the left column. Clicking on another title will clear the text of the first article and display the second. Is there a way to accomplish this without having to repaint the whole page? I would rather not have the whole page resent each time a title is clicked, but rather have the page stay as is and only the contents of the right column get cleared and redisplayed. I assume there's a way to do this with JavaScript, but I don't know how and would appreciate some help. Thanks!

<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %>

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

<head runat="server">
    <form id="form1" runat="server">
        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

Please advice---------

Let me explain this.
// 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" />
<asp:Button Text="Compare" runat="server" ID="btnCompare" OnClick="btnCompare_Click" />

// c#

string strOld = "This a line 1\nThis is going to be line 2\rThis is going to be line 3\rThis is line 4";
string strNew = "This a line 1\nThis text is changed here going to be line 2\rThis is going to be line 3\rThis is changed line 4";

Please note that these strings have \n and \r in it.

When form loads, I do something like this
 if (!IsPostBack)
            txtOld.Text = strOld;
            txtNew.Text = strNew;
Web browser automatically splits the strings and align nicely in the Text box like this
