[Solved] open detailtable edit form

[Duy]

hi i would like to use a linkbutton from a mastertableview to open detailtables edit form. is this possible? thank you.
<telerik:GridTemplateColumn UniqueName="InsertCommandColumn" HeaderText="">
                                <ItemTemplate>
                                    <asp:LinkButton ID="btn_Insert" runat="server" Text="Add Detail" CommandName="InitInsert" />
                                </ItemTemplate>
                            </telerik:GridTemplateColumn>

i was able to do this with 

f e.CommandName = "AddDetail" Then
                Dim parentRow As GridDataItem = TryCast(e.Item, GridDataItem)
                TryCast(e.Item, GridDataItem).Expanded = True
                Dim nestedView As GridTableView = parentRow.ChildItem.NestedTableViews(0)
                If nestedView.Items.Count > 0 Then
                    nestedView.Items(0).FireCommandEvent("InitInsert", [String].Empty)

                End If
            End If

however, if the parent has no child it will crash. So i put the if nestedView.items.count>0 in but how do i overcome this issue so i can still perform insert without having any child. thank you for your help.

anyone has any idea how to fix this? thanks

Hi,

You could achieve your goal by using the following method:

public void ExpandGridRecursively(GridTableView tableView)
{
    GridItem[] nestedViewItems = tableView.GetItems(GridItemType.NestedView);
    foreach (GridNestedViewItem nestedViewItem in nestedViewItems)
    {
        foreach (GridTableView nestedView in nestedViewItem.NestedTableViews)
        {
            if (nestedView.Name == "SearchedTableView")
            {
                nestedViewItem.Expanded=true;
            }
            if (nestedView.HasDetailTables)
            {
                HideExpandColumnRecursive(nestedView);
            }
        }
    }
}

You should replace the "SearchedTableView" with the name of the TableVIew object you want to expand. You could call this method inside the Button click handler and pass the MasterTableVIew object of RadGrid.

Hi Duy,

To insert the record if detail grid not contain any records use the following code -
                           if (e.CommandName == "Add")
                            {
                                GridDataItem parentItem = (GridDataItem)e.Item.OwnerTableView.ParentItem;
                                GridTableView nestedView = parentItem.ChildItem.NestedTableViews[0];
                                if (nestedView != null && nestedView.Items.Count > 0)
                                {
                                    nestedView.Items[0].FireCommandEvent("InitInsert", String.Empty);
                                }
                                else
                                {
                                    nestedView.IsItemInserted = true;
                                    nestedView.Rebind();
                                }
                            }
