HI All,

I am working on a website and I want to display data from two tables
eg CustomerOrder and CustomerDomain.
I want to display the data in gridview.
What i want to display is Customer order Details and Count of CustomerDomains.

C#

try
{
    var query = from po in pc.CustomerDomainTbls
                join co in pc.CustomerOrderTbls
                on po.OrderID equals co.OrderID
                select new {co.OrderDate, co.CustomerTbl.CustomerName, co.EmployeeTbl.Name,co.ServiceTypeTbl.ServiceName, co.QuotedAmount, co.ExpectedCompletionDate };
    gridorders.DataSource = query;
    gridorders.DataBind();
}
catch (Exception rr)
{

}

Can any one help me to get the count of CustomerDomains in gridview.

Thank you very much for quick reply

I think that will help you.

Write the function for RowCount:

private int RowCount
{
    get { return Convert.ToInt32(ViewState["RowCount"]); }
    set { ViewState["RowCount"] = value; }
}

Retrieve this:

C#

using (MYDataClassesDataContext dc = new MYDataClassesDataContext())
{
    var rec = dc.CustomerDomainTbls.FirstOrDefault();
    if (rec == null)
    {
        Response.Write("");
    }
    else
    { 
        try
        {
            var query = from po in pc.CustomerDomainTbls
                join co in pc.CustomerOrderTbls
                on po.OrderID equals co.OrderID
                select new 
               {co.OrderDate, 
              co.CustomerTbl.CustomerName, 
                 co.EmployeeTbl.Name,
            co.ServiceTypeTbl.ServiceName, 
             co.QuotedAmount, co.ExpectedCompletionDate,
             
            Count = dc.po.Count()};
            gridorders.DataSource = query;
            gridorders.DataBind();
        }
        catch (Exception rr)
        {
        }
    }
}
