Hi There,

I have set  GroupsDefaultExpanded = False and am displaying total amounts in the group footer (i.e. ShowGroupFooter="True") and have set GroupLoadMode = Client.

Upon refreshing the page/grid etc, everything looks correct - in terms of collapsed groups, correct totals, the group footer displayed etc.

When I expand the group and then decide to collapse it, I no longer see the group footer displayed and I'm not sure why. If I refresh the page again (using F5 or rebuild the grid), I can see the group footer once more.

Any assistance would be greatly appreciated.

Thanks,
Danielle

Hi Danielle,

One possible option to enable this functionality is to set the  ShowFooter property to "true".
For more information about group footers please look at the following links:
Demo
Help topic

Additionally, if the issue persists, please send me a small runnable application, which would allow me to track the issue locally.
 
I hope this helps.

Thanks for your reply Pavlina.

I looked at the demo, and my application looks similar, however the difference is that my grid displays the "Total Products" (gridgroupfooter) when the section is collapsed. So, upon refreshing/loading up the grid, all groups are collapsed and for each group, the "Total Products" line is displayed. Then, when the group is expanded then collapsed again, the "Total Products" line is not visible (only when you expand it again, then you can see it).

I added the "ShowFooter" property and set it to "True" however this has not helped.

I'm not sure how to add attachments to posts? There doesn't appear to be an attachment button.

What I can provide for now is a copy and paste of my grid (note: columns are added programmatically).

Thanks again,
Danielle

Hi again,

If there's a way of programmatically displaying the footer (I might be doing it incorrectly or not at all in my code), it'd be good to know.

Thanks.

Hello Danielle,

I followed your scenario in order to replicate the issue but not available. Find the attached sample project , which handles the desired functionality. Let me know if this is the expected behavior or I am missing something important.

If the sample cannot help I suggest you to send me modified project so that I can see the issue locally.
To be able to add attachments to posts you should open a formal support ticket.

I hope this helps.

Hi Pavilna,

Thanks for the sample however, it isn't exactly what I was after... I've thought about it and have decided that I'd like the following to occur:

When the group is collapsed, the gridgroupfooter row is hidden. When the group is expanded, the gridgroupfooter row is visible.

I'd like to performm this on client-side if possible (using the GroupCollapsing and GroupExpanding methods).

Eg:

 
 
 
 
function GroupCollapsing(sender, eventArgs)  
{  
var Grid = $find("<%= RadGrid1.ClientID %>");     
var MasterTable=Grid.get_masterTableView();     
           
for(var i=0;i< MasterTable.get_dataItems().length;i++)     
{     
   -- if item type is grid group footer then  
   -- hideitem(index)  
}     
I've read somewhere that the client-side ItemType property is no longer available so how should I be determining whether the item is a gridgroupfooter item or not?

Let me know if this makes sense.

Thanks and Regards,
Danielle

Hi Danielle,

The group footers are most commonly used to visualize calculations from aggregate functions within the scope of the current group.
By design when the group is collapsed, the gridgroupfooter is hidden. When the group is expanded, the gridgroupfooter is visible.
This behavior of the Grid can not be manipulate on the client-side, neither on the server-side.

Thanks for your response Pavlina.

> By design when the group is collapsed, the gridgroupfooter is hidden. When the group is expanded, the gridgroupfooter is visible.

The above is what i'd like to happen now, however it is not happening.

The group footer is still being displayed when the group is collapsed for the first time upon page load but I don't want this to occur. Is there some property or coding that is required in order to hide the groupfooter when collapsed (for the first time?)

Thanks,
Danielle

Hi Danielle,

When collapsing the group for the first time the GroupFooter should not displayed.
You can see this behavior in the sample, which I sent you in the previous post.
Look at again on the following link:
Group footers

Additionally if this not helps, in order to progress in the resolution of this issue, it will be best if you send me a small project which would allow me to track the  issue locally.

Pavlina,

Use the mastertableview code below in the sample project you attached earlier, that I modified to replicate what Danielle is referring to.

<MasterTableView ShowGroupFooter="True" TableLayout="Fixed" AllowMultiColumnSorting="True" 
                DataKeyNames="ProductID" DataSourceID="AccessDataSource1" GroupLoadMode="Client" GroupsDefaultExpanded="false">  
                <CommandItemTemplate> 
                    <asp:Button runat="server" ID="ApplyFilterButton" Text="Apply Filtering" CommandName="MultiFilter" /> 
                    <asp:Button runat="server" ID="ClearAllFiltersLinkButton" Text="Clear All Filters" 
                        CommandName="ClearFilters" /> 
                </CommandItemTemplate> 
                <NoRecordsTemplate> 
                    There are no projects for this plan version.  
                </NoRecordsTemplate> 
                <GroupByExpressions> 
                    <telerik:GridGroupByExpression> 
                        <SelectFields> 
                            <telerik:GridGroupByField FieldAlias="ProductID" FieldName="ProductID" HeaderValueSeparator=":  " /> 
                        </SelectFields> 
                        <GroupByFields> 
                            <telerik:GridGroupByField FieldName="ProductID" /> 
                        </GroupByFields> 
                    </telerik:GridGroupByExpression> 
                </GroupByExpressions> 
                <Columns> 
                    <telerik:GridBoundColumn DataField="UnitPrice" DataType="System.Decimal" HeaderText="UnitPrice" 
                        SortExpression="UnitPrice" Aggregate="Sum" UniqueName="UnitPrice" FooterText="TotalPrice:">  
                    </telerik:GridBoundColumn> 
                    <telerik:GridBoundColumn DataField="ProductID" Aggregate="Sum" DataType="System.Int32" 
                        HeaderText="ProductID" ReadOnly="True" SortExpression="ProductID" UniqueName="ProductID" 
                        FooterText="TotalProduct:">  
                    </telerik:GridBoundColumn> 
                </Columns> 
                <CommandItemStyle BackColor="Beige" VerticalAlign="Top" Font-Bold="True" Font-Size="Small" 
                    HorizontalAlign="Left" />                  
            </MasterTableView> 

As you can see, I added the group by expression and I set the GroupsDefaultExpanded to false.  When you run the project, you will notice that the footer of each group is displayed.  If you expand the group and then collapse it, then the footer disappears.

This is not a consistent feature of the radgrid.  In my honest opinion it should be shown all the time because I would still like to see the summary of each group without having to see all the detail.  To get the best of both worlds, you should add another property that shows the footer when the group is collapsed.  That would solve my problem and Danielle's.

Thanks
Zach

Hi Zach,

Unfortunately I could not reproduced the issue on the live site.
At this point in order to progress in the resolution of this matter it will be best if you can open a formal support ticket and send us a simple running project demonstrating the problem (and step-by-step instructions on doing so). In that way we can reproduce and pinpoint the problems you're facing on our side, understand the logic of your application and provide a solution.

I have the same problem.  I would like to show the group footers on mutiple groupings w/out having to expand the details.  I also have the issue when you go into the details and expand back out the group footer goes away.  There is something going wrong with the codebase somewhere.  It looks like the only way to get the footer to reappear is to expand the last item in the last.  (No I dont have a live site for you to test/view)

Im going to show you what I did using your own grid example to prove my point:
http://mmo-rpg.com/1.png
http://mmo-rpg.com/2.png
http://mmo-rpg.com/3.png

This is what my page looks like:

This is what I want:
Date
    Facility
        Warehouse
Group Footer(Warehouse)
Group Footer(Facility)
Group Footer(Date)

Hello bradley,

I am happy to inform you that the desired feature will be available in the next version of RadGrid for ASP.NET. Then you would be able to choose to show the group footer when group is collapsed or not.

I hope this helps.

Hello Chrysa,

The feature is already implemented and you can test it on the following online demo of the product:
http://demos.telerik.com/aspnet-ajax/grid/examples/groupby/groupfooter/defaultcs.aspx 

The functionality has been included since the Q3 2009 version of the product. Upgrade instructions can be found here.

I had this same problem, but found a good solution to combat the issue.
In-case its not clear, this issue I am referring to...

I have a RadGrid with multiple nested groups. 
Upon the first loading of the page, all footers for all groups are displayed, even with these settings set:

this.Grid.MasterTableView.ShowGroupFooter = true;
this.Grid.MasterTableView.GroupsDefaultExpanded = false;

this.Grid.GroupingSettings.RetainGroupFootersVisibility = true;


Expanding the top level group, then immediately collapsing it causes all footers of child groups to disappear, leaving only the footer of the top level parent.

The problem appears to lie with how the RadGrid deals with the footer's style, which is different then the headers for the groups, i.e. there is a rgGroupHeader style but no rgGroupFooter style.

My solution is to apply a style to each child footer as the items are created. 

   #region Properties
   private int GroupingCount = 0;
   #endregion Properties
 
void Grid_ItemCreated(object sender, GridItemEventArgs e)
{
    if (e.Item is GridGroupHeaderItem)
    {
        ++GroupingCount;
    }
    if (e.Item is GridGroupFooterItem)
    {
        --GroupingCount;
        if (GroupingCount > 0)
        {
            e.Item.Style.Add(HtmlTextWriterStyle.Display, "none");
        }
    }
}

This ensures that upon rendering, each footer not belonging to the top level group will be properly hidden.
Hope this helps!

Hi John,

Thank you for sharing your experience with the community. However, I will appreciate if  you can send us a sample working project which demonstrates this erroneous behaviour, so that we can test it locally and see what is causing it.

Best wishes,

Hi Danielle,

I'm just wandering, is it possible to display the summary rows of each grouping under collapsed mode ?. Summary rows display actually under each grouping but hides automatically when collapsed. What i want is to display the summary rows under each collapse.

However, while researching i stumbled on this link : http://www.telerik.com/help/aspnet-ajax/grid-group-footers.html, but apparently its for asp and not winforms. 

Finally, what i am asking for is the combination of setting the autoexpandgroups to false, and also displaying the summaryrow also

Hi Aghogho,

You can try enabling the following property:
<GroupingSettings ... RetainGroupFootersVisibility="true" />

Hope this helps.

Hi Aghogho,

In that case I suggest that you open a new formal support ticket or a new forum thread choosing the corresponding Product line from the ticket options since this thread concerns RadGrid for ASP.NET AJAX.
