[CLOSED] Combo fails in retrieving matching items with local paging (when typing in the field)

Hi,

You should set up

QueryMode="true"

for the ComboBox.

But it is not enough. Currently, the PagingStore filter method filters the current page records only. It is called internally. We will investigate a possibility to change it.

For now I can suggest the following override of the filter method.

Example

<%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    protected void Store_ReadData(object sender, StoreReadDataEventArgs e)
    {
        Store store = sender as Store;
        store.DataSource = new object[] 
        { 
            new object[] { "1", "a" },
            new object[] { "2", "b" },
            new object[] { "3", "c" },
            new object[] { "4", "aa" },
            new object[] { "5", "bb" },
            new object[] { "6", "cc" }
        };
    }
</script>

<!DOCTYPE html>

<html>
<head runat="server">
    <title>Ext.NET v2 Example</title>

    <script type="text/javascript">
        var myFilter = function (filters, value) {
            if (Ext.isString(filters)) {
                filters = {
                    property: filters,
                    value: value
                };
            }

            var me = this,
                decoded = me.decodeFilters(filters),
                i = 0,
                length = decoded.length;

            for (; i < length; i++) {
                me.filters.replace(decoded[i]);
            }

            if (me.filters.getCount()) {
                me.filterBy(me.filters.get(0).filterFn);
            }
        };

Sorry Daniil,
you say to try QueryMode="true" but in you code I see QueryMode="local"

Is "true" an option for QueryMode?

What will I use?

Thanks
M

**Daniil** · Sep 05, 2012, 10:28 AM

Sorry, it should be

QueryMode="Local"

**marco.morreale** · Sep 05, 2012, 12:58 PM

As I set QueryMode="Local" the list isn't loaded anymore (neither first page).
Do I miss anything else?
M

**marco.morreale** · Sep 05, 2012, 1:06 PM

Sorry Daniil , it was my mistake. I mispalced the CustomConfig tag.

Now:

if I set with QueryMode="true" then
the search is working well but the list loads only the first page

without QueryMode="true"
the search dosn't work but the list loads all the pages correctly

It is a bit difficult to understand. Please clarify what options you are actually using.

Version A (with QueryMode="Local"):
- filter is OK: item in page 2,3,... are found and shown correctly when I type in the field
- paging is not working: il I press th arrow key only the first page is shown in the list. No way to go to the following pages

<ext:ComboBox
                            ID="cmbCustomerLogin" 
                            runat="server"
                            SelectOnFocus="true"
                            EmptyText="seleziona un cliente"                            
                            ForceSelection="true"

Thank you for clarification.

Could you provide a sample for this case? A simple sample like I posted above which we can run locally without any changes.

It's a bit hard to me to build a locally running sample .

Does it help if I provide you with the simple asmx.cs file?

        [WebMethod]
        [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
        public StoreResponseData getCustomerList(string Username)
        {
            DataClassesDataContext dc = new DataClassesDataContext();

            var dataQuery = from d in dc.SP_B2B_GetCustomerList(Username)
                            select new
                            {
                                No_ = d.No_,
                                Name = d.Name
                            };

            var recordList = dataQuery.ToList<object>();
            StoreResponseData storeResponse = new StoreResponseData();
            storeResponse.Data = JSON.Serialize(recordList);
            storeResponse.Total = recordList.Count;
            return storeResponse;
        }
