Gridview

Question

I am storing the value of gridview into a string. I have two lines of code. string UserName = GridView1.Rows[e.RowIndex].Cells[4].Text.ToString(); 1 string UserName = GridView1.Rows[e.RowIndex].Values[UserName].ToString(); 2 Both will have same Values. Which is the better option to use 1 or 2 ?

Hi Shreyas in the above code both are useful and currect but second one is the better and safest thing. becouse of your mentiond Values[UserName] right. here UserName is the DB column name. in your select query u can get UserName only. but first one is select column value [4] th column some times you get another column in that 4th position. like (ex. select idUserNameage Address ) here is the 4th possition Address. so it is not safest that one. u can better use second one Thanks Bharat peggem

Hi Shreyas You can use both interchangeably . But make sure you check the values before assignment because : - Cell value may be null. Instead of .ToString() use Convert.Tostring( GridView1.Rows[e.RowIndex].Cells[4].Text ) . This will catch the null to string cast error . - If you are using the second option make sure the column exists and the name is correct and after click: -If you are using the first option make sure the cell index is correct else index out of bounds error will be thrown .
