    <p>Hi all i seem to be having an issue with LINQ, i am currently maintaining an in house Intranet application at work,When Saving logs it seems to slow down now,upon debugging i have came to realise that every time it saves a log the application pauses at these two section lines of codes.It does save the logs ,just that its slow and at times super slow.</p> <pre><code>DataClassesDataContext dab = new DataClassesDataContext(); dab.SubmitChanges(); </code></pre> <p>My question primarily is ,are there any known issues with those two paticuler lines of code giving any sort of problem that can slow down an application? below is the full code used for inserting ,those who understand better could perhaps analyse it better and perhaps correct me where im wrong.Thanks in advance...</p> <pre><code>DataClassesDataContext dab = new DataClassesDataContext(); newlog = new calllog(); newlog.shortdesc = txtshortdesc.Text; calllog_description.Text ="*****" + Page.User.Identity.Name + " " + DateTime.Now.ToString() + " ***** " + "\r\n" + calllog_description.Text; newlog.calllog_description = calllog_description.Text; newlog.calllog_id = Convert.ToInt32(txtlogid.Text); newlog.calllogrefno = calllogrefno.Text; newlog.pr_id = Convert.ToInt32(pr_id.SelectedItem.Value); newlog.st_id = Convert.ToInt32(st_id.SelectedValue); newlog.product_id = Convert.ToInt32(product_id.SelectedValue); newlog.dep_id = Convert.ToInt32(dep_id.SelectedValue); newlog.log_assigneduser = Convert.ToInt32(log_assigneduser.SelectedValue); newlog.client_id = Convert.ToInt32(DropDownList1.SelectedValue); newlog.log_datetime = System.DateTime.Now; newlog.log_user_id = this.Page.User.Identity.Name; newlog.calllog_internal = calllog_internal.Checked; newlog.notify_client = true; newlog.notify_practise = true; newlog.ct_id = Convert.ToInt32(ct_id.SelectedValue); newlog.resolved = false; dab.calllogs.InsertOnSubmit(newlog); dab.SubmitChanges(); </code></pre>

    1. COThis appears to be LINQ to SQL: Have you checked the SQL being created and checked in SQL Profiler to see if this is a problem on the database?

    2. COJust a short note: I know it's confusing but LINQ is quite different from LINQ to SQL; LINQ is a much more generic concept (Language INtegrated Query) that applies to more than just SQL or a specific SQL dialect, and LINQ to SQL is a very specific ORM library that deals with persisted entities. There are also Linq to Objects, Linq to Entities, Linq to XML etc...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
