I need to update the change textbox when the textbox receives customer value, is filled, I use this function inside the textbox receive customer value in the event Textchanged:
protected void txtvalordocliente_TextChanged(object sender, EventArgs e)
{
if (txtvalordocliente.Text == "")
{
txtvalordocliente.Text = "0";
decimal troco = decimal.Parse(txtvalordocliente.Text.Replace("R$", "")) - decimal.Parse(txtvalorareceber.Text.Replace("R$", ""));
txttroco.Text = troco.ToString();
}
else
{
decimal troco = decimal.Parse(txtvalordocliente.Text.Replace("R$", "")) - decimal.Parse(txtvalorareceber.Text.Replace("R$", ""));
txttroco.Text = troco.ToString();
}
}And here’s my html code, but it either works once in a while or it doesn’t work, I can’t fix it.

Add the code of your entire event and also the page load.
– Aline
I added the event, on the page load, has not related to this code, until I tried to put inside the if (!Ispostback) but it did not work.
– Mariana
Add pageLoad code, because your problem might be there.
– Aline
I added Aline.
– Mariana
Actually Aline, rs now is not even updating, I tried to put updatepanel as always, autopostback as true of all, but no way is working now.
– Mariana
Wait, at what point do you want the value to appear in txttroco? Pq Voce set Autopostback to false in txtvalorareceber..
– Aline
I wanted that when typed in txtvalordoclient txttroco was updated, the field txtvalorareceber, it comes filled automatically.
– Mariana
Hummm, so if you don’t want to give the postback, you’ll have to do with js updating that field.
– Aline
That’s why I use Updatepanel, to update only the textbox, but it’s not working, I use it in other contexts and it works.
