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? Thanks.
Here is my code (NewsContent.as px):
<form id="Form1" method="post" runat="server">
<asp:DataGrid id="DataGrid2" runat="server"> </asp:DataGrid>
</form>
//--------------------------------------------------------------------
Code behind:(NewsCon tent.aspx.cs).
public class NewsContent{
private void Page_Load(objec t sender, System.EventArg s e)
{
ListItemCollect ion myListCollectio n = AddToCustomColl ection();
this.DataGrid2. DataSource = myListCollectio n;
this.DataGrid2. DataBind();
}
private ListItemCollect ion AddToCustomColl ection()
{
ListItemCollect ion myListCollectio n = new ListItemCollect ion();
NewsContent.New sItem myItem1 = new NewsContent.New sItem("viko", "url1",
"today");
NewsContent.New sItem myItem2 = new NewsContent.New sItem("vikan", "url2",
"imorgon");
NewsContent.New sItem myItem3 = new NewsContent.New sItem("kiki", "url3",
"veckan");
myListCollectio n.Add(myItem1);
myListCollectio n.Add(myItem2);
myListCollectio n.Add(myItem3);
return myListCollectio n;
}
//Inner Class which holds all properties needed to show news content and
listings
public class NewsItem
{
public NewsItem()
{
}
public NewsItem(string linkName, string linkUrl, string date)
{
}
public string linkName;
public string linkUrl;
public string date;
public string longDate;
}
}
//---------------------------------------------------------------------------------
I'm using a collection class: (ListItemCollec tion.cs):
public class ListItemCollect ion:CollectionB ase
{
public ListItemCollect ion()
{
//
// TODO: Add constructor logic here
//
}
public NewsContent.New sItem Item(int index)
{
//the appropiate item is retrieved from the list object and
//explicitly cast to the ListItem type, then returned to the
//caller
return (NewsContent.Ne wsItem) List[index];
}
public int Add(NewsContent .NewsItem myNewsItem)
{
return List.Add(myNews Item);
}
}
