asp c#, IE 6.0

I have the following usercontrol. everything works fine except this one

public int producthowmany
{
get {txtproducthowmany.Text; }
set { txtproducthowmany.Text = value; }
}

I tried to call that and it is always saying that string cannot convert to integer. so I put
Int32.Parse() and it still does not work. Any ideas how to fixed it?

public string productname
{
get { return txtproductname.Text; }
set { txtproductname.Text = value; }
}
public string productdescription
{
get { return txtproductdescription.Text; }
set { txtproductdescription.Text = value; }
}
public int producthowmany
{
get { return Int32.Parse(txtproducthowmany.Text); }
set { txtproducthowmany.Text = Int32.Parse(value); }
}
public int productcondition
{
get { return ddlproductcondition.SelectedItem.Text; }
set { ddlproductcondition.SelectedItem.Text = value; }
}
public float productpriceperunit
{
get { return txtproducthowmuch.Text; }
set { txtproducthowmuch.Text = value; }
}

this is failed when the textbox value is null or string.empty

you can check the value before parsing

public int producthowmany
{
get {
int i = 0;
if (txtproducthowmany.Text.Length > 0)
i = Int32.Parse(txtproducthowmany.Text);
return i;
}
set { txtproducthowmany.Text = Int32.Parse(value); }
}

or try this also

public int producthowmany
{
get {
int i = 0;

i = int.TryParse(txtproducthowmany.Text, out i); //check the syntex
return i;
}
set { txtproducthowmany.Text = Int32.Parse(value); }
}

error point to set { txtproducthowmany.Text = Int32.Parse(value); }
to say that it can not convert from string to int.

sabeesh

textProductthowmany.Text is a string value so cannot assign a int value.
try like this
textProductthowmany.Text = value.ToString()
