a strange bug in binding of grid

[lina fetisova]

Good day!
I have got m own class News
I've made a child class NewsForSite

public class NewsForSite : News
    {
        public string SitesTree;
    }

NewsForSite has one more parametr - string SitesTree.

I'm making NewsForSite exemplar on base of News exemplar by coping all the parameters of News to NewsForSite and writing SitesTree string to each NewsForSite.
In debugger (you can see it at attached picture) I can see that all of paramerts of NewsForSite are in base collection and SitesTree parametr is outstanding, and when I try to bind this parametr to grid like other parmetrs, there is an empty space instead of SitesTree stings in grid. Otner columns look well.
I bind all the parametrs this way:

grUsersGroup.DataSource=newsWithSitesList; //( var newsWithSitesList = new List<NewsForSite>();)

<telerik:RadGrid  ID="grUsersGroup" runat="server" >
        <MasterTableView AutoGenerateColumns="False" EditMode="PopUp" DataKeyNames="Id">
             <Columns>
                <telerik:GridBoundColumn DataField="Id" HeaderText="ID"
                    SortExpression="Id" UniqueName="Id" ReadOnly="true">
                </telerik:GridBoundColumn>
                <telerik:GridBoundColumn DataField="SitesTree" HeaderText="Где опубликована"
                    SortExpression="SitesTree" UniqueName="SitesTree" ReadOnly="true" AllowFiltering="true">
                </telerik:GridBoundColumn>            
             </Columns>            
        </MasterTableView>
    </telerik:RadGrid>

what is the right way of binding of SitesTree to me?

Hello Lina,

Please try using the following code and let me know whether it works:

<telerik:RadGrid  ID="grUsersGroup" runat="server" >
        <MasterTableView AutoGenerateColumns="False" EditMode="PopUp" DataKeyNames="Id">
             <Columns>
                <telerik:GridBoundColumn DataField="Id" HeaderText="ID"
                    SortExpression="Id" UniqueName="Id" ReadOnly="true">
                </telerik:GridBoundColumn>
                <telerik:GridBoundColumn DataField="NewsForSite.SitesTree" HeaderText="Где опубликована"
                    SortExpression="SitesTree" UniqueName="SitesTree" ReadOnly="true" AllowFiltering="true">
                </telerik:GridBoundColumn>
             </Columns>
        </MasterTableView>
    </telerik:RadGrid>

For additional information, you can examine the Binding to SubObjects help topic.

Mira, thank you very much, but i'm afraid it doesn't work for me - my SitesTree column is still empty =(

Hello Lina,

Please bind the column to the corresponding property of the class:

public class NewsForSite
{
    private string sitesTree;

    public string SitesTree
    {
        get { return sitesTree; }
        set { sitesTree = value; }
    }
}

ASPX:

<telerik:GridBoundColumn DataField="SitesTree" HeaderText="Где опубликована" SortExpression="SitesTree"
    UniqueName="SitesTree" ReadOnly="true" AllowFiltering="true">
</telerik:GridBoundColumn>

I am also attaching a sample project demonstrating how this works.

I hope it helps.

Sincerely yours,
