Although, if it makes any extra performance, it would be very less and negligible. Those two are two types of approach to the problem.

Choose whatever way is going to be the easiest to read. The performance differences will be negligible in the big picture, but if you 'pre-optimise' your code too much, you could go back to it in a years time and have no idea what you were trying to do...
keep it simple.

hi,
in the datarow bound event you can hide cell.
like.
if(e.row.cell[1].text == "1" || e.row.cell[1].text == "5" )
{
e.row.cell[1].visible == false;
}
format as required.
Thanks,

Hi,
I am publishing my website containg some events in Global.asax file. And I upload my published copy to server. I am getting some errors like which means that server not getting events from Global.asax file. And actually there is not any Global.asax file in my published copy. This does not create any problem to my local server or my local lost.but creates problem in live server. So please give me some idea regarding this.
Thanks in advance.

Hi,
for that you have to use viewstate and have to add arraylist in viewstate, and have to append arraylist on every selecion of row of gridview.

getvalue is value which you are fetching from gridview's selected row.
As you want to add value from grdview.selected row's cell's value.

in the database..in a table..........i have a field named "username".....
in the username. field "Ramesh" is there ..
i want to calculate that how many times "ramesh" is there in the username field..using sql
|

This must be in SQL Forum, this has nothing to do with ASP.NET.
Select count(*) from table where username = 'ramesh'

Is the code to add controls dynamically is written in Page_Init or Page_Load? If you have written the code in the Page_load then it will not behave as you expect it to...and the controls won't participate in the viewState too.
