Hi All,
I would like to be able to create nested datagrids where I can add and edit a record of both the parent and child datagrids inline.

I am able to add/edit the datgrids on there own i.e. Not nested - I have created a datagrid that I can add and edit rows.

I am , however,unsure of how to combine the datagids so that will still be able to add/edit rows of both datagrids.

Any Help would be appreciated.

Thankyou in advance for your help.

Regards,

P

You have to place the grid you want to nest inside of a template column in the main grid.

Hi,
Ok thanks, but when I put my child grid in a template column of the parent grid I can't get my child grid events to fire.



Here is the grid I want to be the parent.


Code: 
<asp:datagrid id="dgCRs" runat="server" ShowFooter="True" BorderStyle="Ridge" BorderColor="LightGray" BorderWidth="1px" DataKeyField="IssueID" AutoGenerateColumns="False" AllowSorting="True" HeaderStyle-Wrap="false" HeaderStyle-Font-Bold="true" HeaderStyle-BackColor="LightGrey" AlternatingItemStyle-BackColor="Linen" CellPadding="2" GridLines="Both" CssClass="tn10">
<EditItemStyle BackColor="#66FFFF"></EditItemStyle>
<AlternatingItemStyle BackColor="WhiteSmoke"></AlternatingItemStyle>
<HeaderStyle Font-Bold="True" Wrap="False" BackColor="LightGray"></HeaderStyle>
<FooterStyle BackColor="LightGray"></FooterStyle>
<Columns>
<asp:TemplateColumn SortExpression="IssueID" HeaderText="Issue ID" ItemStyle-Wrap="True" ItemStyle-Width="100px">
