There is a memory leak when you have a RadGrid that uses client-side binding via setting the OnCommand client event along with a column that has HeaderStyle-Width equal to a percentage value. Explorer cpu usage was static at 13%, and memory was slowly growing. The issue was not reproducible in Chrome.

<telerik:RadGrid ID="rgvStatus" runat="server" GridLines="None" Skin="Outlook" ShowFooter="True" EnableViewState="false">

<MasterTableView AutoGenerateColumns="False">

<Columns>

<telerik:GridBoundColumn HeaderText="Name" DataType="System.String" DataField="Name"

UniqueName="Name" HeaderStyle-Width="40%" />

<telerik:GridBoundColumn HeaderText="Task" DataType="System.String" DataField="Task"

UniqueName="Task" HeaderStyle-Width="40%" />

<telerik:GridDateTimeColumn HeaderText="Time Started" DataType="System.DateTime"

DataFormatString="{0:t}" DataField="TimeStarted" UniqueName="TimeStarted" />

</Columns>

</MasterTableView>

<ClientSettings>

<Scrolling AllowScroll="true" UseStaticHeaders="true" ScrollHeight="250px" />

<ClientEvents OnCommand="pageLoad" />

</ClientSettings>

<FilterMenu EnableImageSprites="False"></FilterMenu>

<HeaderContextMenu CssClass="GridContextMenu GridContextMenu_Default">

</HeaderContextMenu>

</telerik:RadGrid>

The OnCommand function does not have to do anything, it leaks regardless. I was able to work around the issue by using a pixel value for the column widths.
