UpdatePanel / DataGrid / Internet Explorer Lock up

Hi!

I'm facing a strange problem and would like to know if anybody can help me out!
I've a page with 5 UpdatePanels which all use the same asynchronous Postback Trigger (a DropDown Box).

e.g.

<asp:ScriptManagerID="_scriptManager"runat="server"EnablePartialRendering="true">

<Services>

<asp:ServiceReferencePath="../services/positions.asmx"/>

</Services>

</asp:ScriptManager>

<asp:UpdatePanelID="UpdatePanel2"runat="server">

<ContentTemplate>

<asp:GridViewBorderWidth="0"CellSpacing="0"cellpadding="3"Width="100%"ID="grdCash"runat="server"ForeColor="#333333"GridLines="Horizontal"AutoGenerateColumns="False"ShowFooter="False">

<FooterStyleBackColor="#5D7B9D"Font-Bold="True"ForeColor="White"/>

<RowStyleBackColor="#F7F6F3"ForeColor="#333333"/>

<EditRowStyleBackColor="#999999"/>

<SelectedRowStyleBackColor="#E2DED6"Font-Bold="True"ForeColor="#333333"/>

<PagerStyleBackColor="#284775"ForeColor="White"HorizontalAlign="Center"/>

<HeaderStyleBackColor="#5D7B9D"Font-Bold="True"ForeColor="White"/>

<AlternatingRowStyleBackColor="White"ForeColor="#284775"/>

<Columns>

<asp:BoundFieldItemStyle-Width="80"DataField="SEGMENT"HeaderText="SEGMENT/CCY"HeaderStyle-HorizontalAlign="center"ItemStyle-HorizontalAlign="center"/>

<asp:BoundFieldDataField="DATUM"HeaderText="DATUM"HtmlEncode="False"DataFormatString="{0:dd.MM.yyyy}"HeaderStyle-HorizontalAlign="center"ItemStyle-HorizontalAlign="center"/>

<asp:BoundFieldDataField="FREE_CASH"HeaderText="FREE CASH"HtmlEncode="False"DataFormatString="{0:N}"HeaderStyle-HorizontalAlign="left"ItemStyle-HorizontalAlign="left"/>

<asp:BoundFieldDataField="SETT_TRANS"HeaderText="SETT.TRANS"HtmlEncode="False"DataFormatString="{0:N}"HeaderStyle-HorizontalAlign="right"ItemStyle-HorizontalAlign="right"/>

<asp:BoundFieldDataField="CPNS"HeaderText="CPNS"HtmlEncode="False"DataFormatString="{0:N}"HeaderStyle-HorizontalAlign="right"ItemStyle-HorizontalAlign="right"/>

<asp:BoundFieldDataField="REDEMPTIONS"HeaderText="REDEMPTIONS"HtmlEncode="False"DataFormatString="{0:N}"HeaderStyle-HorizontalAlign="right"ItemStyle-HorizontalAlign="right"/>

<asp:BoundFieldDataField="CASH_TRANSFERS"HeaderText="TRANSFERS"HtmlEncode="False"DataFormatString="{0:N}"HeaderStyle-HorizontalAlign="right"ItemStyle-HorizontalAlign="right"/>

<asp:BoundFieldDataField="DEPOSITS"HeaderText="DEPOSITS"HtmlEncode="False"DataFormatString="{0:N}"HeaderStyle-HorizontalAlign="right"ItemStyle-HorizontalAlign="right"/>

<asp:BoundFieldDataField="MAT_TD"HeaderText="MAT.TD"HtmlEncode="False"DataFormatString="{0:N}"HeaderStyle-HorizontalAlign="right"ItemStyle-HorizontalAlign="right"/>

<asp:TemplateFieldHeaderText="VALID"HeaderStyle-HorizontalAlign="center"ItemStyle-HorizontalAlign="center">

<ItemTemplate>

<asp:ImageID="imgValid"BorderStyle="None"runat="server"/>

</ItemTemplate>

</asp:TemplateField>

</Columns>

</asp:GridView>

</ContentTemplate>

<Triggers>

<asp:AsyncPostBackTriggerControlID="drpFonds"/>

</Triggers>

</asp:UpdatePanel>

The strange thing is that after a couple of refreshes (through the async postback trigger drpFonds) the Internet Explorer ( on the client ) locks-up and CPU utilization goes up to 100%.
I use some javascript code on this page, but there aren't any loops or timers (like setinterval etc.)
The partial postback executes some SQL queries and updates the datagrid(s) - nothing else happens.
I can't figure out what's wrong. Can anybody give me some hints on how to debug such a problem?

Thank you!

I had a problem just like that. It turned out that I was using a

Sys.WebForms.PageRequestManager.getInstance().add_endRequest(calledFunction)

without removing it using

Sys.WebForms.PageRequestManager.getInstance().remove_endRequest(calledFunction)

Every time the update panel posted back it added another delegate call to the event. So over time the target function was being called over and over and over until it crashed the browser.

UpdatePanel and "foreign" characters

Hi!

I'm using an UpdatePanel with a DataList inside and a Trigger that updates the panel.

In Explorer no updates are shown if the datalist contains swedish characters ( ?, ? or ?), the trigger works but the "old" content is still shown. This works perfectly fine in FireFox.

Any suggestions?

I tried to simulate this and it appears to be working okay. What I did was have both FormView and DataList for a table within the same UpdatePanel. I've also handled the ItemUpdated event for the FormView and invoked DataList.DataBind() method to refresh the DataList content. Using your swedish characters for one of the FormView updates, it gets reflected to the DataList. I'm using IE version 6.0.
