Hi,
Below JQuery is going to update two cells in UI show or hide:

<pre lang="xml">function DisplayExistingStatus() {
    if($("#<%=IsNew.ClientID %>").val() == $("#<%=hfIsNew.ClientID %>").val()) {
        $("#<%=tdLblECS.ClientID %>")[0].style.display = "";
        $("#<%=tdECS.ClientID %>")[0].style.display = "";
        ValidatorEnable($("#<%= rfvExistingCollStatus.ClientID %>")[0], true);
        //ValidatorEnable(document.getElementById("<%= rfvExistingCollStatus.ClientID %>"), true);
    } else {
        $("#<%=tdLblECS.ClientID %>")[0].style.display = "none";
        $("#<%=tdECS.ClientID %>")[0].style.display = "none";
        ValidatorEnable($("#<%= rfvExistingCollStatus.ClientID %>")[0], false);
        //ValidatorEnable(document.getElementById("<%= rfvExistingCollStatus.ClientID %>"), false);
    }
}

And in page load events, do display/hide with the record which retrieve from DB:

C#

if (this.IsNew.SelectedValue != ViewState["IsNew"].ToString())
{
    this.tdECS.Attributes.Add("style", "display:none");
    this.tdLblECS.Attributes.Add("style", "display:none");
    this.rfvExistingCollStatus.Enabled = false;
}

In order to update one sub column to null when it was hide, I have written one check function:

C#

if ((this.Master.FindControl("Content").FindControl("tdECS") as HtmlTableCell).Style.Value == "display:none")
    collObj.ExistingCollStatus = null;

However, this style can not be updated when UI have been changed.
Wait for help

The problem is:
When page load, the cells tdECS and tdLblECS have "display:none",
Then update to display these two cells,
Click Save button, the style which get in svc side is still "display:none",
OR:
When page load, the cells tdECS and tdLblECS do not have "display:none",
Then update to hide these two cells,
Click Save button, the style which get in svc side is still null.
