VB

Private Sub textbox1_EditValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles textbox1.EditValueChanged
        If textbox1.Text <> "" Then
textbox3.text=cint(textbox1.text)*1
        End If
    End Sub
Private Sub textbox2_EditValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles textbox2.EditValueChanged
        If textbox2.Text <> "" and textbox2.Text <> ""  Then
textbox3.text=cint(textbox1.text)*cint(textbox2.text)
        End If
    End Sub

Solution 4

dim mul as int64
MUL=CONVERT.TOINT64(textbox1.text)* convert.toint64(textbox2.text)
textbox3.text=convert.tostring(mul)

Solution 5

JavaScript Solution is as follows:

JavaScript

function multiply()
{
   
   var textValue1 = document.getElementById('TextBox1').value;
   var textValue2 = document.getElementById('TextBox2').value;

   document.getElementById('TextBox3').value = textValue1 * textValue2;

}

Solution 6

if you want to diplay this value u can write like this.

C#

TextBox3.Text=(Convert.ToInt32(TextBox1.Text)*Convert.ToInt32(TextBox2.Text);

or if u want use this textbox3 value for again calculation purpose means again u need to convert this texbox3 value

like

C#

convert.Toint32(TextBox3.text)

Solution 1

Firstly you need to type cast values of both text boxes into integer.

C#

Example: TextBox3.Text=Convert.ToString(Convert.ToInt32(TextBox1.Text)*Convert.ToInt32(TextBox2.Text));
