Getting List Internal Name

Hi Guys,
I ran into a very wierd but intresting issue today. The client changed the document library name and suddenly even handler started throwing error saying the file path does not matched. Whenever the list name changes, the internal name remains same and the path of the file remains with the internal name. So my properties.ListTitle was picking the display name and could not find the file.

So always better approach is to use list internal name.
Not simple but not even complex:
I used

properties.ListItem.ListItems.List.RootFolder.Name

and it gave me the list internal name and the issue was fixed. Cheers!

So, the basic logic is that, if you want to use list internal name, then you have to follow

objList.RootFolder.Name

Twitter Friends Timeline and oAuth

Hi Guys,

If you guys had done any task regarding Twitter feed webpart, you should know by now that your webpart is not working anymore. The reason being the authentication of twitter has been changed from basic authentication ot oAuth.

currently i am working on my enhancement on twitter webpart to sync the authntication with oAuth. Let me know if you guys need a code snapshots.

Thanks

Gridview to Excel.

Senerio: A gridview hold a data and on a button click we are sending it to Excel letting user to open or save the file. I used this in one of our Sharepoint Webpart.

Assumption: Paging and sorting are enabled. gv is a asp gridview .

protected override void OnPreRender(EventArgs e)
{
gv.AllowPaging = false;
gv.AllowSorting = false;
gv.DataBind();

HttpContext.Current.Response.Clear();
HttpContext.Current.Response.Buffer = true;
HttpContext.Current.Response.ContentType = "application/vnd.ms-excel";
HttpContext.Current.Response.Charset = "";
this.EnableViewState = false;
this.EnableViewState = false;
System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
HtmlForm frm = new HtmlForm();
this.Controls.Add(frm);
frm.Controls.Add(gv);
frm.RenderControl(oHtmlTextWriter);
HttpContext.Current.Response.Write(oStringWriter.ToString());
HttpContext.Current.Response.End();

gv.AllowPaging = true;
gv.AllowSorting = true;
gv.DataBind();
}


Hope it helps and Thank you for Visiting!

Copy a file of Document Library along with its metadata.

The straight forward way to copy a document from document library is to use CopyTo function like:
ListItem.CopyTo(distinationURL+"/"+ListItem.File.Name);
This function will copy the file to distinationURL along with its metadata. But if anyone of the field is a lookup field, then it will not copy any of the meta data. For this purpose you must Copy the file and update its metadata seperately. I have used as following in one of my event handler.

SPFile sourceFile=properties.ListItem.File;
SPFile destFile;
using(Stream stream=soureceFile.OpenBinaryStream())
{
destFile=properties.ListItem.Web.Lists[properties.ListTitle].RootFolder.Files.Add(distinationURL,stream,true);
}

SPListItem destinationListItem=destFile.Item;
//Then start copying the metadata as following
destinationListItem["Title"]=properties.ListItem["Title"];
destinationListItem["abc"]=properties.ListItem["abc"];
//copying lookupfield
string partsOfField=properties.ListItem["lookupField"].ToString().Split(';');
destinationListItem["lookupField"]=new SPFieldLookupValue(int.Parse(partsOfField[0].ToString()), partsOfField[1].ToString());

destinationListItem.Update();


Hope it helps!
