how can I bind data to DetailTable dynamically.

Hi. I have a radgrid. It has DetailsTable in MasterTableView. Iwant to load data to detail tables dynamically, but I can not.
I wrote code like below.

grdItemRules.DataSource = rules;

grdItemRules.DataBind();

foreach (GridDataItem item in grdItemRules.MasterTableView.Items)

{

GridTableView tableView = (GridTableView)item.ChildItem.NestedTableViews[0];

tableView.DataSource = rules[item.ItemIndex].RuleItems;

tableView.DataBind();

}

My code block is like above. Can anyone help me about this? Thanks in advance.

HeaderStyle, ItemStyle, and FooterStyle are not applied to new rows added while on batch mode

Greetings,

If I have a column setup as follows:

<telerik:GridTemplateColumn UniqueName="Store_Code" DataField="Store_Code" DataType="System.Int32">

</EditItemTemplate>

<InsertItemTemplate>

</InsertItemTemplate>

<ItemTemplate>

<%# Eval("Store_Code") %>

</ItemTemplate>

<HeaderStyle CssClass="serial-column" />

<ItemStyle CssClass="serial-column" />

<FooterStyle CssClass="serial-column" />

</telerik:GridTemplateColumn>

When I add rows to the grid while on batch mode, I don't find the serial-column CSS class applied to the cells.
