Question

I am passing data value, to a database, using integer data type (accepting null).

If in front-end I do not pass any integer it takes null value in db. While retrieving table data in front-end I am using if condition to filter the integer empty values. I have only integers to display, how to write the if condition?

int x;
if(x!=(which code this place write)
{
textbox.text=x; //x value not empty working if condition else goto else condition
}
else
{
}

Answer 1

 if (dt.Rows[0]["ToAge"] == DBNull.Value)

Hope it helps
