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

All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia

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.

Problem With Global.asax File When Publish

28-Nov-07 22:08

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,
Sun Rays

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.

This must be in SQL Forum, this has nothing to do with ASP.NET.

Select count(*) from table where username = 'ramesh'

Hi,
do this.

DropDownList ddlMy = new DropDownList();<br />
ddlMy.Items.Add("test");<br />
ddlMy.Items.Add("test1");<br />
ddlMy.Items.Add("test2");<br />
ddlMy.Items.Add("test3");<br />
ddlMy.Items.Add("test4");<br />
ddlMy.AutoPostBack = true;<br />
ddlMy.SelectedIndexChanged += new EventHandler(ddlMy_SelectedIndexChanged);<br />
this.form1.Controls.Add(ddlMy);<br />

And create one event for that.

void ddlMy_SelectedIndexChanged(object sender, EventArgs e)<br />
{<br />
    lblMyDDL.Text =((DropDownList)sender).SelectedItem.Text; // print in label<br />
}
