There is repeater in my program includin a hyper link.i cant a cess my hyper link control.

<asp:HyperLink ID="HyperLink15" runat="server" NavigateUrl="abc.aspx">

    HyperLink link = (HyperLink)Repeater1.FindControl("HyperLink15");
    link.Enabled=true;
    link.Navigateurl="efg.aspx";

Repeater onItemDataBound Event first check below condition.

if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
 // find controls here
}

HyperLink a = (HyperLink)Repeater1.Items[0].FindControl("HyperLink15");

Use above, and Items will contain index.

Or

for (int count = 0; count < Repeater1.Items.Count; count++)
        {
            HyperLink a = (HyperLink)Repeater1.Items[count].FindControl("HyperLink15");
        }
