Hi,

See the WebCast of TechDays 2007 at
http://www.microsoft.com/france/vision/WebCastMSDNTechDays.aspx?EID=B....
It's in French but Renaud Compte shows how to create a Web Part able to
query list using SPQuery and display result in a SPGridView.

Hi
I am writing a web part where I want to show a contact list but use one
of the views define for that contact list. I do not want to use the list
view web part but basically want to write my own list view web part with
some UI in addition to what the list view will show. Can anyone tell me
how I can display a view associated with a list in a customized web part.

Thanks

Here's a simple list viewer I wrote... Hope this helps.

public class WebPartListViewer3 :
Microsoft.SharePoint.WebPartPages.WebPart
{

//var for the name of the list
private string _listName;

[Browsable(true)]
[Description("The name of the list you want to show")]
[FriendlyName("List Name")]
[WebPartStorage(Storage.Shared)]
public string listName
{
get { return _listName; }
set { _listName = value; }
}

//var for the name of the view
private string _viewName;

[Browsable(true)]
[Description("The name of the view you want to show")]
[FriendlyName("View Name")]
[WebPartStorage(Storage.Shared)]
public string viewName
{
get { return _viewName; }
set { _viewName = value; }
}

protected override void Render(HtmlTextWriter writer)
{

try
{
if (_listName == null)
{
writer.Write("Please Set List Name");
}
else
{

string[] pathSplit = _listName.Split('/');

SPWeb root = SPControl.GetContextWeb(Context);
int x = 0;
while (x < pathSplit.Length-1)
{

if (pathSplit[x] != "")
{
root = root.Webs[pathSplit[x]];
}
x++;
}

SPList finalList = root.Lists[pathSplit[x]];

SPView collView = finalList.DefaultView;
SPListItemCollection Coll =
finalList.GetItems(collView);

writer.Write("<table border=1 cellpadding=2
