RadGrip Group Collapses Upon Entering Inline Edit Mode

[RYNETECH]

Greetings,

I'm using the following RadGrip markup.  By default the grid renders with all groups collapsed.  When I expand a group, I see all items, but if I edit an item, I lose the expansion of the group and only see the item that I'm editing.  Upon exiting edit mode, I am returned to a collapsed group, causing me to have to re-expand and search for the item that I was working with.  How can I cause the group to remain expanded upon editing and/or exiting edit mode?

Hi ,

Please try the sample code snippet to prevent the rows from collapsing.

ASPX:

<telerik:RadGrid ID="RadGrid1" runat="server" OnNeedDataSource="RadGrid1_NeedDataSource"
    OnGroupsChanging="RadGrid1_GroupsChanging" OnItemCommand="RadGrid1_ItemCommand"
    AutoGenerateEditColumn="true" OnPreRender="RadGrid1_PreRender">
    <ClientSettings AllowDragToGroup="True">
    </ClientSettings>
    <MasterTableView GroupLoadMode="Server" GroupsDefaultExpanded="False" EditMode="InPlace">
        <GroupByExpressions>
            <telerik:GridGroupByExpression>
                <GroupByFields>
                    <telerik:GridGroupByField FieldName="Group" />
                </GroupByFields>
                <SelectFields>
                    <telerik:GridGroupByField FieldName="Group" />
                </SelectFields>
            </telerik:GridGroupByExpression>
        </GroupByExpressions>
    </MasterTableView>
    <ClientSettings EnableRowHoverStyle="true" AllowGroupExpandCollapse="True" AllowDragToGroup="False"
        Selecting-AllowRowSelect="true">
        <Scrolling AllowScroll="false" UseStaticHeaders="true" />
    </ClientSettings>
</telerik:RadGrid>
