C# - Updating A XmlDataSource At Runtime?
Jul 7, 2010
I have this DropDownList bound to a XmlDataSource, but the XPath must depend on another input (another DropDownList). I modify the XPath and rebind inside the parent DDL's SelectedIndexChanged, but the page does not refresh. What should I do to display the update?
protected void ProductDropDownList_SelectedIndexChanged(object sender, EventArgs e)
{
CompMapping.XPath = "//couple[@product='" + ProductDropDownList.SelectedValue + "']";
CompMapping.DataBind();
ComponentDropDown.DataBind();
}
ComponentDropDown is set to AutoPostBack=True, but that's not enough. Could it be related to the fact both DropDownLists are in a UserControl?

I've created an asp:ListView and attached it to an asp:XmlDataSource. I would like to support the delete command for my list, so I've added the following button:
<asp:Button runat="server" CommandName="Delete"
Text="Del" CausesValidation="false" />
It throws an 'Specified method is not supported'.how to implement this delete?

I am Trying to build a Treeview Control using an XMLDataSource which consumes a XML file (which is set dynamically) . The Problem is that the XML file Size is huge, arround .5 MB so the page load is hit because of this . Now i know that there is a PopulateOndemand Property of the treeview and there is also a populateondemand property of Treenodebinding which is used in XMLDataSource .

my code is as follows
DataSet ds = new DataSet();
string connStr = "Data Source=PARITAS00024;Initial Catalog=MenuDb;Persist Security Info=True;User ID=sa;Password=paritas123";
using (SqlConnection conn = new SqlConnection(connStr))
{
string sql = "Select MenuId, MenuTitle, MenuDesc, MenuURL, ParentMenuId from tblMenus where Status=1 and RecordStatus=1 order by ParentMenuId, DisplayOrder";
SqlDataAdapter da = new SqlDataAdapter(sql, conn);
da.Fill(ds);
da.Dispose();
}
ds.DataSetName = "Menus";
ds.Tables[0].TableName = "Menu";
DataRelation relation = new DataRelation("ParentChild", ds.Tables["Menu"].Columns["MenuId"], ds.Tables["Menu"].Columns["ParentMenuId"], true);
relation.Nested = true;
ds.Relations.Add(relation);
System.Web.UI.WebControls.XmlDataSource xds = new System.Web.UI.WebControls.XmlDataSource();
xds.TransformFile = "~/TransformXSLT.xsl";
xds.XPath = "MenuItems/MenuItem";
xds.Data = ds.GetXml();
xds.ID = "xmlDataSourceMenu";
Menu1.DataSource = xds;
Menu1.DataBind();
is this correct way of using the xmldatasource ?

I'm creating page to put together a list of cinema trailers on an asp.net web page inside of a repeater.
The source of the data is an online XML feed.
To do this I'm binding the repeater as follows...
string XML_FEED_URL = "http://some-cinema-feed.com/comingsoon/";
XmlDataSource data_source = new XmlDataSource();
data_source.DataFile = XML_FEED_URL;
data_source.XPath = "/movies/movie[position() > 0 and position() < 3]";
this.moviePreciewsRepeater.DataSource = data_source;
this.moviePreciewsRepeater.DataBind();
The issue is that the length of the feed changes regularly and rather than selecting a range of movies with the XPATH (i.e. 1-3 in the XML) I need to select 3 totally random movies from the XML and bind this back to the repeater.

I'm using XmlDataSource as the datasource for a dropdownlist. Now I want to set the SelectedValue of the dropdown when the page initially loads. I tried the OnDataBound event of the dropdown in which I could see the total items but setting the SelectedValue didn't work. In OnDataBinding event, I couldn't even see the total items probably because the list isn't bound yet.

I have XML like this:
<?xml version="1.0" encoding="UTF-8"?>
<viewentries timestamp="20100923T130205,90Z" toplevelentries="8903">
<viewentry position="1" unid="A4958CC88435D1A8422577A7004422E8" noteid="4DF15A" siblings="8903">
<entrydata columnnumber="0" name="$59">
<text>63722</text>
</entrydata>
<entrydata columnnumber="1" name="$70">
[Code].....
However, if I save the same xml to a file to my computer, it works without a glitch.

I have a master page that hosts a user control to load my menus from the database depending on the user logged in.So when ever a user logs in, the menu list corresponding to him is loaded into the XMLDatasource that is the Data source for the menus.Following is the code:
[Code]....
The problem is if I log out as one user and Login as another, the XML Data source is not invalidating the cache... and is loading the same values again ..Further I even noticed that the program flow control is not transfered to the LoadMenus.ascx control at times and the page is loaded with out having to go through the control flow of all the controls on the master page. i am not sure how to force the control to pass through a single control.I have set the EnableCaching to false on the xml data source.

I have a GridView tied to an XmlDataSource to take advantage of the edit/update/delete capabilities GridView inherently offers. XmlDataSource offers no update event handling so that must be performed manually. I have no problem with this. My problem is how/where can I catch this update event to perform my custom handling.

So I sometimes use app_offline.htm to take an app offline while I upload a new version.However, while I am in the process of uploading larger dll's, I get the yellow error-screen saying the dll could not be loaded.This seems to be out of sync with my expectations of what app_offline.htm does (stops the app entirely), and also provides the users with errors in stead of the nice app_offline.htm I put up.Am I doing something wrong or is this behavior by design?
