    var result = confirm("Want to delete all Deals?");

    } else {
        return false;

try like this:

function btnDeleteClick() {
var confirm_value = document.createElement("INPUT");
 confirm_value.type = "hidden";
 confirm_value.name = "confirm_value";
 confirm_value.value = "No";
var result = confirm("Want to delete all Deals?");
if (result) {
    confirm_value.value = "Yes";
    __doPostBack('DeleteDealsButton', '')
    return true;
} else {
    confirm_value.value = "No";
    return false;
}
}

In your .Aspx file Change your button code to like this:

<asp:Button ID="DeleteDealsButton" OnClientClick=" return btnDeleteClick()" runat="server" Text="Delete" OnClick="DeleteDealsButton_Click" />

In your .Aspx.cs file

protected void DeleteDealsButton_Click(object sender, EventArgs e)
    {
     string confirmValue = Request.Form["confirm_value"];
     if (!String.IsNullOrWhiteSpace(confirmValue) && confirmValue.Equals("Yes"))
     {
     }
}

Just change button defination to,

<asp:Button ID="DeleteDealsButton" runat="server" Text="Delete" OnClientClick="return confirm('Want to delete all Deals?')" />

No need for any javascript function.
