Hello<br>
<br>
I am trying to perform some math operations in Silverlight<br>
<br>
inputNum1 and inputNum2 are of TextBox<br>
<br>
inputNum1 = TextBox()<br>
inputNum2 = TextBox()<br>
<br>
result0 = int(inputNum1) + int(inputNum2)<br>
</blockquote></div>
That's because you can't cast text boxes to integers!<br>
<br>
You need something like:<div class="im"><br>
<br>
result0 = int(inputNum1.Text) + int(inputNum2.Text)<br>
<br></div>
You'll probably want to strip whitespace and also handle the error case where what the user has entered is not a valid integer.<br>
<br>
HTH<br>

res0.Text = str(result0)<br>
<br>
I get the following error<br>
<br></div>
<<a href="http://go.microsoft.com/fwlink/?LinkID=124807" target="_blank">http://go.microsoft.com/fwlink/?LinkID=124807</a>> TypeError: expected int, got TextBox<br>
<br>
Any ideas<br>
