    <p>The code mentioned below is part of my webpart on sharepoint 2010.</p> <pre><code>public class class1 : System.Web.UI.WebControls.WebParts.WebPart { protected override void Render(HtmlTextWriter writer) { string s1 = "first"; string s2 = "second"; string s3 = "third"; slist.Add("first"); slist.Add("second"); LinkButton b; writer.Write("&lt;div id='tblSegment' &gt;&lt;table &gt;"); foreach (string s in slist) { //b = new LinkButton(); //b.Text = s; //b.Click += (sender1, e1) =&gt; { b_Click(sender, e, s1, s2, s3); }; writer.Write("&lt;tr&gt;&lt;td &gt;"); writer.Write("&lt;a href='' &gt;"); writer.Write(s + "&lt;/a&gt;"); writer.Write("&lt;/td&gt;&lt;/tr&gt;"); } writer.Write("&lt;/table&gt;&lt;/div&gt;"); } void b_Click(object sender, EventArgs e, string s1, string s2, string s3) { UpdateList(s1,s2,s3); } public void UpdateList(string ID, string column, string value) { using (SPSite oSPsite = new SPSite("http://server")) { using (SPWeb oSPWeb = oSPsite.OpenWeb()) { oSPWeb.AllowUnsafeUpdates = true; // Fetch the List SPList list = oSPWeb.Lists["UserProfiles"]; //create Query SPQuery query = new SPQuery(); query.Query = string.Concat( "&lt;Where&gt;&lt;Eq&gt;", "&lt;FieldRef Name='ID'/&gt;", "&lt;Value Type='String'&gt;" + ID + "&lt;/Value&gt;", "&lt;/Eq&gt;&lt;/Where&gt;"); //get List Item SPListItemCollection listItems = list.GetItems(query); SPListItem item = listItems[0]; //update List Item item[column] = value; item.Update(); oSPWeb.AllowUnsafeUpdates = false; } } } } </code></pre> <p>I am kind of stuck here, what i need to do is to update a sharepoint list item based on some values(s1,s2,s3), for which i have created method UpdateList. I need to call UpdateList method whenever any hyperlink is clicked. I tried to use link buttons but as expected they did not worked(commented) with htmltextwriter, so i added two simple anchor tags. But how to fire the click event now.</p> <p>I read about system.web.services but unable to make it work. The only option i can think of now is to create a seprate web service with method <code>UpdateList</code> in it kind of thing and make a ajax call to it.</p> <p>Can any body suggest something else or is it somhow possible to use ASP.Net colrols(eg LinkButton) with <code>Htmltextwriter</code>.</p>

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.
