It is button click event. while click the button the page should post back and bind the data how to bind a textbox value in a label box using c#. The value must bind in postback method.

Answer 1

It as easy as the following:

LabelID.Text = TextBoxID.Text;

Where LabelID is the ID of your Label control and TextBoxID is the ID of your TextBox control.

You should place this code inside the button click's event.

Update

Please use for your purpose ASP.NET Web Server Controls .

<asp:TextBox ID="textBoxId" runat="server"/>

<asp:Label ID="labelId" runat="server"/>

Then you can access the values of Text property of both the above controls, like above:

labelId.Text = textBoxId.Text;

Answer 2

easy , take a look at the below code:

<asp:TextBox Id="txt1" runat="server" />

<asp:button Id="btn1" runat="server" onClick="Button1_Click"/>
<asp:Label Id="lbl1" runat="server"/>

//in the code behind implement the Button1_Click

protected void Button1_Click (object sender, EventArgs e)
{

lbl1.Text= txt1.Text;

}
