EP Hyperlink and Button Context issue

Hi,

I have created one link to view total for Sales Quotation but its showing same value for all customer account.

How to write the code for button/link to get the current value of context. Here is the code and its not getting the current value.

<asp:LinkButton ID=“LinkHeaderNotes” runat=“server” OnClick=“LinkHeaderNotes_Click”>Enter Header Notes </asp:LinkButton>

protected void LinkHeaderNotes_Click(object sender, EventArgs e)
{
DataSetViewRow dsvrSalesQuotationTable = this.ds_SalesQuotation.GetDataSourceView(“SalesQuotationBasket”).DataSetView.GetCurrent();
string windowStatus = Labels.GetLabel("@SYS68926");

if (dsvrSalesQuotationTable != null)
{
using (IAxaptaRecordAdapter record = dsvrSalesQuotationTable.GetRecord())
{
AxUrlMenuItem urlMenuItem = new AxUrlMenuItem(“EPDocuList”);
urlMenuItem.MenuItemContext = AxTableContext.Create(AxTableDataKey.Create(this.AxSession, record, null));
urlMenuItem.RemoveNavigation = true;
Response.Redirect(urlMenuItem.Url.OriginalString);
//LinkHeaderNotes.HRef = “#”;
// LinkHeaderNotes.Attributes.Add(“onfocus”, “javascript: window.status = '” + windowStatus + “’”);
// LinkHeaderNotes.Attributes.Add(“onmouseout”, “javascript: window.status = ‘’”);
// LinkHeaderNotes.Attributes.Add(“onclick”, “javascript: window.open(’” + urlMenuItem.Url.OriginalString + “’, ‘’, ‘width=700,height=700,menubar=0,toolbar=0,status=0’); return false;”);
}
}
}
