Write below javascript function on OnClientClick of Delete button.

JavaScript

function checkForDelete() {
        var gridId = '<%=GridView1.ClientID %>';
        var checkedInput = $('#' + gridId).find('tr td input[type="checkbox"]:checked').length;
        var allInput = $('#' + gridId).find('tr td input[type="checkbox"]').length;
        if (checkedInput == 0) {
            alert('Select at least one record');
            return false;
        }

        return true;
    }

C#

<asp:imagebutton id="ButonDeleteClient" runat="server" height="60px" imageurl="~/Images/Delete.png" onclientclick="return checkForDelete();" onclick="ButonDeleteClient_Click" tooltip="Delete selected customer's information" width="60px" xmlns:asp="#unknown" />
