Loading : slow performance

[GOURVEZ JJ]

Hi,

I use radgridview and I have an problem to performance in loading.

If my screen resolution is 800X600, the loading is 5 second, but if my screen resolution is 1600x1200, the loading during 15 second.
Do you have an idea ?

I put MaxHeight and MaxWidth in my gridview.

For information, I have 150 columns and I use HeaderCellStyle (for each column) and 20 Converters.

Can you help me ?

Thanks

Hi Gourvez JJ,

I will need some more details on how your RadGridView is set up  e.g. XAML  , datasource used etc.
Meanwhile there is a simple check you can perform   - are there any binding expression errors in the output window of VisualStudio while RadGridVIew is loading .

Hi,

Thanks for your answer.

This is my code :

--STYLEHEADER

     <Style  TargetType="gridView:GridViewHeaderCell" x:Key="MyHeaderCellStylePink">
                <Setter Property="Background" Value="Pink" />
                <Setter Property="Foreground" Value="Black" />
                <Setter Property="BorderBrush" Value="LightGray"></Setter>
            </Style>

--RADGRIDVIEW

Hello,

 It is not clear from the pasted code what is causing your problems. 

Please send us (via support ticket) small example project demonstrating your scenario and the slow loading.
