You will need to use similar method with the Grid View.  You will need to use cell template in order to bind complex object property. Here is the snippet:

<ISWebGrid:WebGridColumn Caption="Sun ETID" Name="SunETID" ColumnType="Template">
<CellTemplate>
    <asp:Label ID="Label1" runat="server" Text='<%# Eval("Sunday.ETID") %>'></asp:Label>
</CellTemplate>
</ISWebGrid:WebGridColumn>

Hi Glenn,

Thanks for the response, but I tried that already and got the error:

DataBinding: 'System.DBNull' does not contain a property with the name 'ETID'.

I've also tried brackets around the Eval like this:

<asp:Label ID="Label1" runat="server" Text='<%# Eval("[Sunday.ETID]") %>'></asp:Label>

and get the error:

DataBinding: '[Sunday' is not a valid indexed expression.

I've also tried this:

<ISWebGrid:WebGridColumn Caption="Sun ETID" Name="SunETID" ColumnType="Template" DataMember="Sunday">
<CellTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Eval("ETID") %>'></asp:Label>
</CellTemplate>
</ISWebGrid:WebGridColumn>

Which returns the error:

DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'ETID'.

I'm inserting my test page as a code snippet...it includes a standard Gridview, a telerik RadGrid, and an Intersoft Webgrid...also note that I have a test page with nothing but the Webgrid and it still doesn't work.

The Webgrid is the only control that won't bind to "Sunday.ETID"

Thanks for your help!

In my test the template cell method works. Attached is the sample page I used to test the template cell.

I create a simple datatable with a column which hold a complex object which is bound to WebGrid and GridView. The data is shown correctly in both WebGrid and GridView.

I am already using the latest build of WebGrid 7 and WebUI Framework

Thanks so much for your help Glenn.

Sorry to say that I'm working in VB.Net and while I can get your C# example to work, when I translate the code to VB.Net, it doesn't work.

Both projects have the same references.  Both test pages have the same html/code on the aspx page.

I'm inserting the VB codebehind, which should be an exact translation of your C# example, can you see what would make it not work??

Glenn,

Thank you for your help.

Your example works fine.

However, there is still something wrong within my class file...it binds perfectly well in all other data controls..but not WebGrid.

I needed to move on so I just re-wrote the query and object so that it would work with Webgrid.

Thanks for your help though!
