Solution 5

Use the ToString method with required format as shown below:

C#

txtDept.Text = emp.DepID.ToString();
txtSalary.Text = emp.salary.ToString("N2");

The question was not clear. If it is required to convert the string representation of the number to its native value then there are several approaches. One option is to use Convert.ToInt32, Convert.ToDecimal etc. methods as these will not throw exception even when the input value is null as shown below:

C#

emp.DepID=Convert.ToInt32(txtDept.Text);
emp.salary=Convert.ToDecimal(txtSalary.Text);

- well i already checked for null in other function so am sure in this step it will not get null...

- the other thing here is( if ) i used the.tostring(); it wont work because it will show me the column name not the value and also it wont work well because i must use the text boxes to the their values as parameters to the database columns so am i understand it right or not?

Hi,
You can use emp.DepID.ToString();

txtSalary.text = emp.salary.ToString();

Good answer. 5! only thing is the txtDept.text and emp.DepId are to be swapped. Similarly in other statement.

Mohamed Mitwalli 21-May-12 7:13am

Maybe he want bind retrieved data to controls
it can be like this
var emp = (from x in db.emp
select x).FirstOrDefault();
txtSalary.text =Convert.ToDecimal( emp.salary)

VJ Reddy 21-May-12 7:19am

But I think the final statement may throw the error Cannot implicitly convert type 'decimal' to 'string'

Mohamed Mitwalli 21-May-12 7:26am

Yes it will throw error if it contains letters like this Convert.ToDecimal("aa"); but if it already digit it will be okay Convert.ToDecimal("10.5");

VJ Reddy 21-May-12 7:35am

I am thinking that txtSalary.Text is property of string type and a decimal value is being assigned to it.

Thank you :)

Mohamed Mitwalli 21-May-12 7:39am

yes you are right from the beginning didn't noticed

Mohamed Mitwalli 21-May-12 7:41am

It will throw Error :( txtSalary.text it's already string and iam trying to assign to it decimal or int sure it will throw exception

VJ Reddy 21-May-12 7:52am

OK. Finally our thoughts converged to the same point.

Thank you :)

Solution 7

Write .ToString in both the statement.

C#

txtDept.text = emp.DepID.ToString();
txtSalary.text = emp.salary.ToString();

To Convert String Int or Decimal Use

C#

Convert.ToInt32(string_name);//To Convert into Int
Convert.ToDecimal(string_name);//To convert into decimal
