[CLOSED] GridPanel with Proxy and Summary

[ViDom]

Greetings. Whether I don't know you can help me. I have GridPanel with Proxy:

<ext:GridPanel ID="GridPanelMain" runat="server" SelectionMemory="Enabled">
                            <Store>
                                <ext:Store ID="StoreMain" runat="server" RemoteSort="true">
                                    <Proxy>
                                        <ext:HttpProxy Method="GET" Url="~/SharedData/DicListExtHandler.ashx" />
                                    </Proxy>
                                    <AutoLoadParams>
                                        <ext:Parameter Name="start" Value="0" Mode="Raw" />
                                        <ext:Parameter Name="limit" Value="50" Mode="Raw" />
                                        <ext:Parameter Name="sort" Value="" />
                                        <ext:Parameter Name="dir" Value="" />
                                    </AutoLoadParams>
                                    <SortInfo Field="Id" Direction="DESC" />
                                </ext:Store>
                            </Store>
                            <BottomBar>
                                <ext:PagingToolbar ID="PagingToolbar1" runat="server" PageSize="50">
                                    <Plugins>
                                        <ext:SlidingPager />
                                    </Plugins>
                                    <Items>
                                        <ext:ToolbarSeparator runat="server" />
                                         <ext:Label runat="server" Text="Summary Cost:" />
                                        <ext:TextField runat="server" Width="80" Text="$????" ReadOnly="true" />

                                        <ext:ToolbarSeparator runat="server" />
                                        <ext:Label runat="server" Text="Avg Cost:" />
                                        <ext:TextField runat="server" Width="80" Text="$????" ReadOnly="true" />
                                    </Items>
                                </ext:PagingToolbar>
                            </BottomBar>
                       </ext:GridPanel>

Only in "~/SharedData/DicListExtHandler.ashx" i have access to the data to count the sums. I understand that this data could be sent through Proxy:

context.Response.Write(JSON.Serialize(new Paging<object>(rangeData, data.Count)));

But in what format and as them to receive in GridPanel the summary data I do not know ((

Thanks.

Hi,

Store doesn't read any custom information from response

You have to make separate ajax request to the server (for example, to http handler) using ajax request (for example, Ext.Ajax or pure XmlHttpRequest), return required information, parse and handle response on the client side

Sorry, I did not understand your last post

[ViDom]

Or to send the data in the additional row??

[Vladimir]

Yes, you can it as additional (last) row

<Load Handler="TextField1.setValue(records[records.length-1].get('fieldname'));" Delay="10"/>

[ViDom]

OK. I have:

<Listeners>
                                        <Load Handler="???" Delay="10" />
                                    </Listeners>
<View>
                                <ext:GridView runat="server" StandardHeaderRow="true">
                                    <HeaderRows>
                                        <ext:HeaderRow>
                                            
                                        </ext:HeaderRow>
                                    </HeaderRows>
                                </ext:GridView>
                            </View>

How i can get the FooterRow, and recive data from the Store where my row have column "id" always and in summary row "id" == -1?
And how i can remove the Summary Row from the GridPanel visibility rows?

[Vladimir]

1. Please note that Load is Store listener
2. What is FooterRow?
3. To delete additional row

<Load Handler="TextField1.setValue(records[records.length-1].get('fieldname')); this.remove(records[records.length-1]);" Delay="10"/>

FooterRow is this HeaderRow which is allocated bottom.

[Vladimir]

Does your HeaderRow contain fields? If yes then you can get fields by id.
I am not sure why do you need to get HeaderRow, what are you try to do with HeaderRow?
