Group aggregate without displaying the group panel

[Xaria D]

I wish to get the group aggregate.
Basically the count of items in each group, but I do not wish to display the data as group under grid View.

Hello Xaria D,

You can disable the appearance of the group panel by the property of the grid ShowGroupPanel:

<telerik:RadGridView Name="playersGrid"
                     ItemsSource="{Binding Players}"
                     ShowGroupPanel="False"
                     AutoGenerateColumns="False">

 
In this case your groups, if predefined in xaml or in the code-behind, will appear in the group row but no group will be shown at the top. However, this will not allow you the group by the UI. 
You can find more information about controlling the appearance in our online documentation.

All the best,

Hello

Check out online demos-I think that there was an example with aggregate functions:

I have found it - Something like this:This is from the example from demos:

        <telerik:RadGridView x:Name="RadGridView1" ItemsSource="{Binding Customers}" CanUserFreezeColumns="False" AutoExpandGroups="True" AutoGenerateColumns="False">

            <telerik:RadGridView.GroupDescriptors>

                <telerik:GroupDescriptor Member="Country">

                    <telerik:GroupDescriptor.AggregateFunctions>

                        <telerik:CountFunction Caption="Total customers:" />

                    </telerik:GroupDescriptor.AggregateFunctions>

                </telerik:GroupDescriptor>

            </telerik:RadGridView.GroupDescriptors>

            <telerik:RadGridView.Columns>

                <telerik:GridViewDataColumn Header="CustomerID" DataMemberBinding="{Binding CustomerID}" />

                <telerik:GridViewDataColumn Header="CompanyName" DataMemberBinding="{Binding CompanyName}" />

                <telerik:GridViewDataColumn Header="ContactName" DataMemberBinding="{Binding ContactName}" />

                <telerik:GridViewDataColumn Header="ContactTitle" DataMemberBinding="{Binding ContactTitle}" />

                <telerik:GridViewDataColumn Header="Country" DataMemberBinding="{Binding Country}" />

                <telerik:GridViewDataColumn Header="City" DataMemberBinding="{Binding City}" />

            </telerik:RadGridView.Columns>

        </telerik:RadGridView>

    </Grid>

</Examples:GridViewExample>

The full example is in DataGridView-Grouping->Aggregates...

Hope this helps!

The thing is if  use Group descriptor then it will group the data together and display it as group.
I do not wish to change the display of data, i.e. I do not wish to display group of data.
I only want the aggregate.

Hello Xaria D,

 
I am sending you a sample project which implements a solution for taking the result of the Aggregate Functions. In this case the grouping is done on clicking on the button and the result is shown in the TextBlock next to it.

It works like a charm.
Thank you so much.
