When we are making a registration form or a form having many
textboxes] in a single page and we have to clear all the
textboxes at once after submission, what we do is write dozens of lines for every
textbox out there in form or page.
If you have one or two
textboxes, then it is ok.
textbox-id.Text=""; and it will clear the
But when we have many
textboxes in a single page of form, then we have to use something better to do that and here this code comes in.
So just read, understand and apply it.
You need a little bit of information about how to create a control in ASP.NET from code-behind.
Using the Code
Here, I have taken a
div in which I have placed my
textbox and other controls in it.
<div id="feedback" runat="server">
<asp:TextBox ID="name" runat="server" ></asp:TextBox>
<asp:TextBox ID="email" runat="server" ></asp:TextBox>
<asp:TextBox ID="text" runat="server"
CssClass="feedbacktextbox" TextMode="MultiLine" >
<asp:Button ID="b1" CssClass="feedbackbtn"
runat="server" Text="Submit" OnClick="b1_Click" />
So, now on code-behind, when button is clicked, it runs the code in which a
foreach-loop loops through our division and finds the
TextBox control, wherein code below
b is Control which will loop through our division.
c is a
textbox control we declared.
And what will happen after that is below:
protected void b1_Click(object sender, EventArgs e)
foreach ( Control b in feedback.Controls )
if (b is TextBox)
c = b as TextBox;
if (c != null)
c.Text = String.Empty;

Using this will save us from writing dozens of lines to clear
So, guys, use it or leave it. It's your choice. :)
