How to add a textbox with default value ?

Question

Hi,

I have this code fragment:

<div class="DetailsBoxContent">
  <asp:UpdatePanel runat="server" ID="Run Report" UpdateMode="Conditional">
    <ContentTemplate>
      <asp:Panel ID="pnlGenerateRpt" runat="server">
        <div style="padding: 10px; text-align: center; width: 100%; float: right;">
          <asp:Button ID="btnGenerateRpt" runat="server" CssClass="StdButton" Text="Generate Report" OnClick="btnGenerateRpt_Click" />
        </div>
      </asp:Panel>
    </ContentTemplate>
    <Triggers>
      <asp:PostBackTrigger ControlID="btnGenerateRpt" />
    </Triggers>
  </asp:UpdatePanel>
</div>

I would like to add a label & textbox right to the existing button. The textBox needs to have a default value of 0 but can be amended by user.

How to achieve this ?

Thank you

Ok, so right below the button, add this:

    <asp:Label ID="Label1" runat="server" Text="Enter a number"
        style="margin-left:12px" Font-Size="Medium">
    </asp:Label>
    <asp:TextBox ID="txtNumber" runat="server"
        Text="0"
        style="margin-left:10px" Font-Size="Medium"
        TextMode="Number">
    </asp:TextBox>

Note how we used "margin-left to space things over as much as we like.

And I did use text mode = number. This will prevent the user from enter of non numbers

The result is thus now this:

so, you can just drag + drop in the label, then the text box.

The "bonus" part is how we space out things to the right.

(using that simple trick of margin-left is nice, since then we don't have to add a bunch of extra messy markup or even perhapas a "table". A simple drop control, move over a bit with margin-left makes this easy. And do the same trick for the text box if you want to space it over a bit more (or less).

Hi @Bill Johnson,

This can either be done in the markup (.aspx) like:

<asp:TextBox id="txt" runat="server" Text="0" /> Or in the code-behind (.aspx.cs):

TextBox1.Text = 0.ToString();
