What exactly you need? Do you need to access lblHrs or lblDetectHrs or lblPtohrs ?

Santhosh23 7-Oct-13 2:58am

lblHrs

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 7-Oct-13 3:34am

That is not inside Footer, so why are you searching it inside Footer?

Santhosh23 7-Oct-13 3:56am

my query is Sum of total hours display in lblHrs. this label belong to item template field so its possible for display total hours in Item template label.

My question is why you are searching it inside footer row as it is not present in footer.

lblHrs is not in your footer template. lblDetectHrs and lblPtohrs are.

You can't. There isn't one. The item template is for records. The footer template defines what your footer looks like. They aren't the same thing.

Displaying Total in Footer of GridView[^]

Go through the link

C#

float value=0;

if (e.Row.RowType == DataControlRowType.DataRow)
{

    Label lblhr = (Label)e.Row.FindControl("lblhrs");
    value+= float.Parse(lblhr.Text);
}

if (e.Row.RowType == DataControlRowType.Footer)
{
    Label cal = (Label)e.Row.FindControl("lblDetectHrs");

    System.Globalization.CultureInfo culin = new System.Globalization.CultureInfo("hi-IN", true);
    cal.Text = (value.ToString("C", culin)).Remove(0, 2).Trim();
 }

use repeater Item Databound event to find control in item template.

declare a string as global variable.

C#

string globalString = string.empty;

if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
    Label lblName = new Label();
    lblName = (Label)e.Item.FindControl("lblName");
    globalString = lblName.Text;
}

Here the item templates label value is stored in globalString, Now find control of footer template,

C#

if (repeater.Items.Count == 0)
{
    Label ltl = rptContacts.Controls[repeater.Controls.Count - 1].Controls[0].FindControl("Label") as Label ;

    if (ltl != null)
    {
        lt1.text = globalString;
    }
}

i thinks this may help you.
