I got this error:

Input string was not in a correct format.

Source Error:

Line 63:         protected void btn_save_add_Click(object sender, EventArgs e)
Line 64:         {
Line 65:             pcd.Pro_Comp_ID = Convert.ToInt32(txt_prod_of_compID_add.Text);
Line 66:             
Line 67:             //int companyId = Convert.ToInt32(ddl_choose_companyName.SelectedValue);

I revise 'Pro_Comp_ID' in sql and .net it all of datatype 'int' where is the error?

Report

check if the textbox have value or null

if(string.IsNullOrEmpty(txt_prod_of_compId_add.Text))
{
// its null textbox
}
else
{
// not null, do what ever you want
}
