I have a several text boxes available on a form. At the bottom of the form there is a disabled text box for the total. I currently can add all the values upon a button click, however I would like to, if possible, make it so as a form is filled in, the total adds within the total text box.
I thought maybe something like: -
txtbxTotal.text = txtbxTotal.Text + (list of other text boxes)
-
I am running into two issues, I don't know how if at all I can code it to increment in real time as the fields are updated, and I also don't know how to do something like a try parse when I am accepting decimal values.
Any help with either problem are greatly appreciated.
3 6342
With regards to adding the values of decimals and verifying that they contain only numbers and a single decimal, I call a try on my method that adds the values, and a catch on the format error exception and that allows me to make sure it is acceptable numbers being used.
Still need help with the live update in the total text box though.
Awesome. This is what I ended up with in case anyone in the future wants an example: -
private void txtbxOnes_TextChanged(object sender, EventArgs e)
-
{
-
try
-
{
-
AddValues();
-
}
-
catch (FormatException)
-
{
-
//do nothing
-
}
-
}
-
-
if (txtbxOnes.Text == "")
-
ones = 0;
-
else ones = Convert.ToInt32(txtbxOnes.Text);
-
-
txtbxTotal.Text = ones; //and then whatever other text box values are needed.
-
Thanks textmo
I will look at the tryparse for doubles, I ended up using a try catch on the addvalues() method that catches a format error that gets kicked up if a letter or symbol is used.

Hi
I want to update data hold in several textbox controls on an asp.net form.
But it seems like it is the old textbox values that is "re-updates" through a
stored procedure who updates a SQL tabel. I know the SP works, because a
smalldatetime-field in the database is changed. I've tried to disable
viewstate on all textbox controls.
Any ideas to solve this problem.

I am developing a web form which is going to be used for manufacturing
