title: Setting size of textbox control inside modal dialog
body: <p>Firstly I'm fairly new to the coding scene so please so easy on me. I have an issue where I am putting a text box control inside of a modal dialog window however I cannot seem to get the textbox to resize to take up the full size of the modal window. It just seems to take up half the width of it.</p>
  
  <p>This is how I'm creating my modal window and as you can see I've tried to set the width of the textbox however it doesn't appear to be working:</p>
  
  <pre><code>&lt;div id="BusinessRejectModal" class="modal fade" role="dialog"&gt;
      &lt;div class="modal-dialog"&gt;
          &lt;div class="modal-content"&gt;
              &lt;div class="modal-header"&gt;
                  &lt;button type="button" class="close" data-dismiss="modal"&gt;&amp;times;&lt;/button&gt;
                  &lt;h4 class="modal-title"&gt;Enter reason for rejection&lt;/h4&gt;
              &lt;/div&gt;
              &lt;div class="modal-body"&gt;
                  &lt;asp:TextBox ID="txtBusinessRejectModal" runat="server" Height="300px" TextMode="MultiLine" Width="1000px"&gt;&lt;/asp:TextBox&gt;
              &lt;/div&gt;
              &lt;div class="modal-footer"&gt;
                  &lt;button type="button" class="btn btn-primary btn-lg" data-dismiss="modal"&gt;Close&lt;/button&gt;
              &lt;/div&gt;
          &lt;/div&gt;
      &lt;/div&gt;
  &lt;/div&gt;

  <p>I've tried playing around with different width values in the bootstrap.css file however no luck. Can anyone see what I need to do to format this text box properly?</p>
