[Solved] Performance test of RadGridView

[Satish J]

Hi,

     I was evaluating the performance of RadGridView upon 10000 records and  found my application to hang. Tried this and got the same results every time. I saw in your demo which has a stunning performance when binding a million records. I have used 

DataLoadMode="Asynchronous" still  not much difference. Can you please help me on this.

Thanks,
Satish J

Hello Satish J,

How many columns you have in this grid? Currently the grid cells are not horizontally virtualized however this will be added for Q3 release.

Kind regards,

Hi Satish J,

In this case you should not have any performance problems. Can send us small demo project (via support ticket) where we can reproduce this slowness?

Hi Vlad,

           Please find the snippet which can be used to reproduce the problem.

var data = from i in Enumerable.Range(0, 10000)
                       select new MyClass()
                       {
                           SomeIntValue = i,
                           SomeStringValue = String.Format("String{0}",i)
                       };

MyGrid.ItemsSource = data;

Xaml code:

                <tg:RadGridView Name="MyGrid" DataLoadMode="Asynchronous" AutoGenerateColumns="False">
                    <tg:RadGridView.Columns>
                        <tg:GridViewDataColumn Header="ID" DataMemberBinding="{Binding SomeIntValue}"/>
                        <tg:GridViewDataColumn Header="String" DataMemberBinding="{Binding SomeStringValue}"/>
                    </tg:RadGridView.Columns>
                </tg:RadGridView>

Thanks,
