There is no time interval.

If you want to get the time interval for 30 minutes go for javascript

Create TimeSpan values for the values, then you can simply do arithmetic with them. Example:

TimeSpan start = new TimeSpane(9, 30, 0);
TimeSpan stop = new TimeSpan(21, 30, 0);
TimeSpan interval = new TimeSpan(0, 30, 0);

for (TimeSpan s = start; s <= stop; s += interval) {
   Console.WriteLine(s.ToString());
}

You can add image control in grid by selecting edit temlate on smart link and add image control on it.

Set image's data bindinig on smart link. you can hav it from database or from disk.

dear deepak. first of all add an template column in grid & in item template drag & drop an image control & set its image URL. this will show same image in all row. if you want show different images on different row u want to dynamically create path for different images in your stored procedure.

You can write a function that returns image path and call then while the grid is binding.

printf("Navaneeth!!")

No MAN. it is possible.

put a place holder on aspx page where u want to show label.

add this code in page load event.

Label lblU = new Label();

lblU.Text = "deepak chandra";

PlaceHolder1.Controls.Add(lblU);

check it
