I'm getting this error message when trying to request my web application: Access to the path "c:\windows\microsoft.net\framework\v1.1.4322\Temporary ASP.NET Files\root\6afc08f4\6af070d3" is denied. What could be the reason and how to solve that? Notice that I could not root\6afc08f4\6af070d3 folders in 'Temporary ASP.NET Files' folder. IIS is configured to point to the right directory and first page. Thanks for any help.

I'm trying to sort data (by startdate and descendant) in a collection object (CollectionActivities.Sort("StartDate", 0);) and print these data within a datable during run time. Everything is o.k. except the sorting order which is not working. Notice that the same collection(CollectionActivities) is sorting well when It is returned to the caller and bound to a datagrid. My solution require that I use the first way. Any help is highly appreciated. Here is my code: //Enumeration to define the sort orders protected enum enuSortOrder:int { soAscending = 0, soDescending = 1 } private void Page_Load(object sender, System.EventArgs e) { ListScopesWithActivities() } public void ListScopesWithActivities() { ListItemCollectionByScope CollectionScopes = new ListItemCollectionByScope(); ListItemCollectionByScope CollectionGoalDescriptions = new ListItemCollectionByScope(); ListItemCollectionByScope CollectionActivities = new ListItemCollectionByScope(); string colRedImage = ""; string colGreenImage = ""; // Define the child controls Table _table = new Table(); TableCell _tableCell; TableRow _tableRow; _table.ID = "InfoTable"; _table.CellPadding = 0; _table.CellSpacing = 0; _table.BorderColor = Color.Tan; _table.BorderWidth = Unit.Pixel(0); _table.BorderStyle = BorderStyle.Solid; _table.GridLines = GridLines.Both; //Get collection of scopes PageDataCollection pdc = Global.EPDataFactory.GetChildren(MogulEPiServer.GetPage(CurrentPage.PageLink.ID).PageLink); if(pdc.Count > 0) { foreach(PageData pd in pdc) { ListActivityItemByScope liScope = new ListActivityItemByScope(); //Get the property values for Scope from PageName string strScope = MogulEPiServer.PageName(pd.PageLink.ID); liScope.Scope = strScope; CollectionScopes.Add(liScope); //Create the row for Scope _tableRow = new TableRow(); _tableCell = new TableCell(); _tableCell.ColumnSpan = 5; _tableCell.Text = "
Område: " + liScope.Scope; _tableRow.Cells.Add(_tableCell); _table.Rows.Add(_tableRow); //Get collection of GoalsDescriptions PageDataCollection pdc2 = Global.EPDataFactory.GetChildren(MogulEPiServer.GetPage(pd.PageLink.ID).PageLink); foreach(PageData pd2 in pdc2) { //Get property values for GoalDescription if(MogulEPiServer.GetPage(pd2.PageLink.ID).Property["GoalDescription"].Value !

I wonder if it is possible to create multiple datagrids during runtime and bind these to records of data. I tried the following code but it did not work. Any help is very appreciated. foreach(....) { // for every loop the collection of objects will contain different data //and will be bound to a different datagrid control int numberOfGoals; for(int i = 0; i< numberOfGoals; i++) { DataGrid activityDatagrid = new DataGrid(); activityDatagrid.ID = i.ToString(); activityDatagrid.AutoGenerateColumns =true; activityDatagrid.DataSource = CollectionActivities;//collection of objects activityDatagrid.DataBind(); Page.Controls.Add(activityDatagrid.ID); } }

I'm trying to bind a custom collection to an autogenerated datagrid without success. I'm getting this error: DataGrid with id 'DataGrid2' could not automatically generate any columns from the selected data source. Could you help me to find a solution? What is the problem in my code? Feel free to fix in my code.Thanks. Here is my code (NewsContent.aspx):

The problem is that I have an autogenerated columns datagrid so the number of columns displayed in the grid will vary from time to time. It will be difficult to Show each column's total in the footer because the number of columns is unknown. How can I determine in which footer column I will show which total of the column? Thanks

In an autogenerated datagrid I will be showing an unknow number of colums and rows with info as statistics as well the total of the rows in the Datagrid's footer.

Thanks Here is my code: Void ComputeSum(Object sender, DataGridItemEventArgs e) { 'First, make sure we are dealing with an Item or AlternatingItem if (e.Item.ItemType == ListItemType.Item) || (e.Item.ItemType == ListItemType.AlternatingItem) { 'Snip out the ViewCount int viewCount = _ Convert.ToInt32(DataBinder.Eval(e.Item.DataItem, "ViewCount")) viewCountSum += viewCount } }
