[Solved] Grid scrolling hang browser

[Alejandro Vazquez]

Hi Telerik team!

We have a grid which is loaded with 10000 records maximun (usually just a couple hundreds) and we are grouping by one of its fields. Everything was going fine until our browsers starts to freeze after we played a little (really short time) with the scroll. We were working long time to find the reason, but everthing seems to point to the grid itself and we are pretty worried because we really need the scroll working properly.  We are sure that it is not a browser related issue because we tested our application in Explorer, Firefox, Opera, etc. and the trouble appears in all of them. One thing that we realised is that the problem seems to disappear if we don't use grouping... but it is the main reason because we are using the telerik grid. By the other hand, we tryied to put the grid into a scrollViewer object and besides of we lost the grid header while scrolling it takes too much time to render the grid when there are more than 1000 or 2000 records. So we really appreciate if you could give us some idea in order to solve our issue as soon as posible.

The grid is the following one:

 

 

<Grid x:Name="LayoutRoot" ShowGridLines="True">
<Grid.RowDefinitions>
<RowDefinition Height="50" />
<RowDefinition /> 
<Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="200" />
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<app:SearchFilter x:Name="searchFilter" Grid.Row="0" Grid.ColumnSpan="2" />
<grid:RadGridView x:Name="grdDatos" IsReadOnly="True"
ItemsSource="{Binding SearchResult}"
DataLoaded="grdDatos_DataLoaded"
ShowColumnFooters="True"
RowLoaded="grdDatos_RowLoaded"
AutoGenerateColumns="False"
ShowGroupPanel="False"
IsFilteringAllowed="False"
RowIndicatorVisibility="Collapsed"
CanUserFreezeColumns="False"
ColumnsWidthMode="Fill"
GridLinesVisibility="Vertical"
Grid.Column="1"
Grid.Row="1"
VerticalAlignment="Top" Margin="0">
<grid:RadGridView.GroupDescriptors>
<telerikData:GroupDescriptor Member="Project"/>
</grid:RadGridView.GroupDescriptors>
<grid:RadGridView.Columns>
<grid:GridViewDataColumn Header="Project" DataMemberPath="Project" />
<grid:GridViewDataColumn Header="ID" DataMemberPath="Id" Width="60" />
<grid:GridViewDataColumn Header="Title" DataMemberPath="Title" />
<grid:GridViewDataColumn Header="Text2" DataMemberPath="Text2" />
<grid:GridViewDataColumn Header="Text3" DataMemberPath="Text3" />
<grid:GridViewDataColumn Header="Text4" DataMemberPath="Text4" TextWrapping="Wrap" UniqueName="Text4" />
<grid:GridViewDataColumn Header="Date1" DataMemberPath="Date1" DataFormatString="{}{0:MM/dd/yyyy}" Width="75" />
<grid:GridViewDataColumn Header="Date2" DataMemberPath="Date2" DataFormatString="{}{0:MM/dd/yyyy}" UniqueName="Date2" />
<grid:GridViewDataColumn Header="Text5" DataMemberPath="Text5" />
</grid:RadGridView.Columns>
</grid:RadGridView>
</Grid>

Thanks in advance !!
