the problem is this i have TextBoxes and m trying to convert their value to int by using this code:

C#

SqlCommand cmd = new SqlCommand();
        cmd.CommandText = "insert into yearly (pcode,fyyear,yearlyalloc,salary,ta,contigency,nrc,institcharges,others) values (@pcode,@fyyear,@yearlyalloc,@salary,@ta,@contigency,@nrc,@institcharges,@others)";
        cmd.Parameters.AddWithValue("@pcode", DropDownList1.SelectedItem.ToString());
        cmd.Parameters.AddWithValue("@fyyear", TextBox10.Text +"-"+ TextBox2.Text);
        cmd.Parameters.AddWithValue("@yearlyalloc",Convert.ToInt32(TextBox3.Text));
        cmd.Parameters.AddWithValue("@salary", int.Parse(TextBox4.Text));
        cmd.Parameters.AddWithValue("@ta", int.Parse(TextBox5.Text));
        cmd.Parameters.AddWithValue("@contigency", int.Parse(TextBox6.Text));
        cmd.Parameters.AddWithValue("@nrc", int.Parse(TextBox7.Text));
        cmd.Parameters.AddWithValue("@institcharges", int.Parse(TextBox8.Text));
        cmd.Parameters.AddWithValue("@others", int.Parse(TextBox9.Text));

but i am getting error "Input string was not in a correct format" as i was told that i cant leave a textbox blank with convert.toint32 statement. so i wanna use int.TryPrase statement for inserting data.

if U want All that field would be Mandatory then Just Use Javascript validation Or Other Validation Methods.then Save Ur Data In This Case U have To enter correct Value For All Fields and U can use TryParse or Convert or Parse it will not thorow error . U Can Google it with keyword Client Side Validation/Server side validation in ASP.net..etc....

I said to check it first using tryParse: i m getting an error "Input string was not in a correct format.". i am not able to figure out y ?[^] not to replace the Convert.ToInt32 with int.Parse

For example:

C#

int salary;
if (!int.TryParse(TextBox4.Text, out salary))
   {
   // Report error
   return;
   }
...
   cmd.Parameters.AddWithValue("@salary", salary);
