Question

can we assign a data column value to a variable and use this variable in different method.
i have the following code

button_click()
{
create and fill data set as data adapter.fill(data set,"ABC"); 
and then 
int x= data set.tables["ABC"].rows[0]["col name"] ;
}

and i have another method button_click2()
{
int y = x;
}

can i do this? or is there any way i can assign the data set.tables[“ABC”].rows[0][“col name”] value directly to x

If you create the variable out side the method you will be able to use it anywhere within the class.

public class Test
{
     private int ColValue {get;set;} //This is a property

     button_click()
     {
          ColValue = Convert.ToInt(dataset.tables["ABC"].rows[0]["col name"].ToString()) ;
     }

     button_click2()
     {
         int y = ColValue ;
     }
}
