GridFilters + HttpProxyStore + Hanlder ||How to pass the param

<ext:HttpProxy Method="POST" Url="/Handler/GetStore.ashx" />

How to pass the filer text to the handler?

Hi,

Use BaseParams or AutoLoadParams of Store*

When using Paging, Grid on first page loads up and shows 'NaN'

.vb (Sample on Page Load)

Code:

---


            ' Load Product
            ProductsStore.Proxy.Add(New HttpProxy() With {.Method = HttpMethod.GET, _
                                    .Url = Core.Web.ProcessController.ProductGroup.GetAllProductsForProductGroupHandlerUrl() _
                                    })

            ' Use for Paging...
            ProductsStore.AutoLoadParams.Add(New Parameter() With {.Name = Core.Constants.START_PARAM, .Mode = ParameterMode.Raw, .Value = "={" + Core.Constants.START_PARAM_NUMBER + "}"})
            ProductsStore.AutoLoadParams.Add(New Parameter() With {.Name = Core.Constants.LIMIT_PARAM, .Mode = ParameterMode.Raw, .Value = "={" + Core.Constants.LIMIT_PARAM_NUMBER + "}"})
            ProductsStore.BaseParams.Add(New Parameter() With {.Name = Core.Constants.PRODUCT_GROUP_ID, .Mode = ParameterMode.Raw, .Value = "={" + CStr(999) + "}"})

.aspx (Grid)

Code:

---

            <ext:GridPanel ID="gpProductGroupList" runat="server" Height="300px" AutoWidth="true"
                StoreID="ProductsStore" TrackMouseOver="true" Title="Manage Product Names" StripeRows="true"
                AutoScroll="true" AutoDataBind="true" AutoExpandColumn="ProductName">
                <ColumnModel ID="ColumnModel2" runat="server">
                    <Columns>
                        <ext:Column ColumnID="ProductId" DataIndex="ProductId" Header="Product Code" Sortable="true" />
                        <ext:Column ColumnID="UPCCode" DataIndex="UPCCode" Header="UPC Code" Sortable="true" />
                        <ext:Column ColumnID="ProductName" DataIndex="ProductName" Header="Product Name"
                            Sortable="true" />
                    </Columns>
                </ColumnModel>
                <View>
                    <ext:GridView ID="gvProduts" runat="server" ForceFit="true" EnableRowBody="true" />
                </View>
                <SelectionModel>
                    <ext:CheckboxSelectionModel ID="CheckboxSelectionModel1" runat="server" HideCheckAll="true"
                        SingleSelect="false" />
                </SelectionModel>
                <BottomBar>
                    <ext:PagingToolbar ID="PagingToolBar1" runat="server" PageSize="20" DisplayInfo="true"
                        DisplayMsg="Displaying items {0} - {1} of {2}" EmptyMsg="No items to display" />
                </BottomBar>
                <LoadMask ShowMask="true" Msg="Loading..." />
            </ext:GridPanel>

.aspx (Store)

Code:

---

    <ext:Store ID="ProductsStore" runat="server" RemoteSort="true" AutoLoad="false">
        <Reader>
            <ext:JsonReader Root="Data" ReaderID="ProductId" TotalProperty="TotalRecords">
                <Fields>
                    <ext:RecordField Name="ProductId" Type="String" />
                    <ext:RecordField Name="MarketID" Type="String" />
                    <ext:RecordField Name="ProductName" Type="String" />
                    <ext:RecordField Name="UPCCode" Type="Int" />
                    <ext:RecordField Name="FreshDryIndicator" Type="String" />
                    <ext:RecordField Name="EquivalentUnits" Type="Int" />
                    <ext:RecordField Name="JobTag" Type="Int" />
                    <ext:RecordField Name="ActiveFlag" Type="Int" />
                    <ext:RecordField Name="LastModifyUserID" Type="Int" />
                    <ext:RecordField Name="LastModifyDateTime" Type="Date" />
                    <ext:RecordField Name="InsertionDateTime" Type="Date" />
                    <ext:RecordField Name="InGroup" Type="Boolean" />
                </Fields>
            </ext:JsonReader>
        </Reader>
        <Listeners>
            <Load Fn="selectRows" />
        </Listeners>
    </ext:Store>

Or within the Javascript like below...

Code:

---

  ProductsStore.load({ params: { productGroupID: record.ProductGroupID} });

I solved my issue which I found on your Forum, "[CLOSED] Remote paging GridPanel"

I used this below:

Code:

---

            ProductsStore.BaseParams.Add(New Parameter() With {.Name = Core.Constants.START_PARAM, .Value = "={" + Core.Constants.START_PARAM_NUMBER + "}"})
            ProductsStore.BaseParams.Add(New Parameter() With {.Name = Core.Constants.LIMIT_PARAM, .Value = "={" + Core.Constants.LIMIT_PARAM_NUMBER + "}"})
