I thought this was too low a count to be real so I think I may be doing something wrong.

This is the class I load
        public int CMGSecurityID { get; set; }
        public string Portfolio { get; set; }
        public string Cusip { get; set; }
        public string Description { get; set; }
        public string Ticker { get; set; }
        public Decimal Coupon { get; set; }
        public DateTime? Maturity { get; set; }
        public DateTime EffectiveDate { get; set; }
        public Decimal Price { get; set; }
        public string Currency { get; set; }
        public Decimal FxRate { get; set; }
        public string Source { get; set; }
        public string SecurityType { get; set; }

which is contained in a list
       public class CMGSecurityCollection : List<CMGSecurity>, IBindingList

which i stored in a query class
      class SP_Security
          public CMGPositionRecCollection RecCollection { get; set; }

Then I attach that to the grid via
       gridViewSecurities.ItemsSource = ((SP_Security)query).RecCollection;

The grid itself is pretty straight forward
            <telerik:RadTabItem Header="Securities" Name="tabItemSecurities">
                <StackPanel Orientation="Vertical">
                    <TextBlock Name="securitiesTitle"></TextBlock>
                    <telerik:RadGridView x:Name="gridViewSecurities" AutoGenerateColumns="False">
                        <telerik:RadGridView.Resources>
                            <ContextMenu x:Key="MyContextMenu" Opened="ContextMenu_Opened">
                                <MenuItem Header="Details" Name="mnuDetails" Click="ShowSecurityDetails" />
                            </ContextMenu>
                        </telerik:RadGridView.Resources>
                        <telerik:RadGridView.Columns>
                            <telerik:GridViewDataColumn UniqueName="Portfolio" HeaderText="Portfolio" DataMemberBinding="{Binding Portfolio}"/>
                            <telerik:GridViewDataColumn UniqueName="Cusip" HeaderText="Cusip" DataMemberBinding="{Binding Cusip}"/>
                            <telerik:GridViewDataColumn UniqueName="Description" HeaderText="Description" DataMemberBinding="{Binding Description}"/>
                            <telerik:GridViewDataColumn UniqueName="Ticker" HeaderText="Ticker" DataMemberBinding="{Binding Ticker}"/>
                            <telerik:GridViewDataColumn UniqueName="Coupon" HeaderText="Coupon" DataMemberBinding="{Binding Coupon}"/>
                            <telerik:GridViewDataColumn UniqueName="Maturity" HeaderText="Maturity" DataMemberBinding="{Binding Maturity}"
                                DataFormatString="{}{0:yyyy-MM-dd}" />
                            <telerik:GridViewDataColumn UniqueName="EffectiveDate" HeaderText="EffectiveDate" DataMemberBinding="{Binding EffectiveDate}"
                                DataFormatString="{}{0:yyyy-MM-dd}" />
                            <telerik:GridViewDataColumn UniqueName="Price" HeaderText="Price" DataMemberBinding="{Binding Price}"/>
                            <telerik:GridViewDataColumn UniqueName="Currency" HeaderText="Currency" DataMemberBinding="{Binding Currency}"/>
                            <telerik:GridViewDataColumn UniqueName="FxRate" HeaderText="FxRate" DataMemberBinding="{Binding FxRate}"/>
                            <telerik:GridViewDataColumn UniqueName="Source" HeaderText="Source" DataMemberBinding="{Binding Source}"/>
                            <telerik:GridViewDataColumn UniqueName="SecurityType" HeaderText="SecurityType" DataMemberBinding="{Binding SecurityType}"/>
                        </telerik:RadGridView.Columns>
                    </telerik:RadGridView>
                </StackPanel>
            </telerik:RadTabItem>

which all works pretty well with just a few items .

OMG, this post saved me! I had a similiar situation where my gridview began having data loading issues all of a sudden. I didn't make any significant changes, so I could not figure out why it started taking so long to load the data and to select all and selecting individual rows. I created a test control and put it insdie a grid and it worked perfect retrieving from the same data. Just by luck I added a stack panel and that test control began having the same issues. So I created another test control and that one was working fine. Comparing the two, the only difference I noted was that the slow one was insde a stack panel, the good one was inside a grid. So I narrowed it to the stack panel and I found this thread.
The only thing that on my project, I had my gridview not insde a StackPanel but a grid, however, the height of the row it was in was set to Auto (*) which gave it the same effect.
Thanks, Vlad, I am very greatful for your response as it explained it to me.
