Dynamic Filters not showing...

[rthiney]

Hi,
I'm trying to add filter dynamically. I'm creating the store and the grid columns dynamically..
Everything works great, except that my filters aren't showing...


Here is my code behind

private void AddField(Store store, RecordField field)
        {
            if (Ext.IsAjaxRequest)
                store.AddField(field);
            else
                store.Reader.Reader.Fields.Add(field);
        }
        public void LoadGrid(Store store, GridPanel grid,  bool testData)
        {
            try
            { 
                store.RemoveFields();

                //loop through each column to create the readerfields for the store
                foreach (FundScreenerReportColumn c in this.Columns)
                    this.AddField(store, new RecordField(c.ColumnName, RecordFieldType.Auto));

                //ADD GRID COLUMNS/FILTERS
                Column col = null;
                StringFilter sFilter = null;
                NumericFilter nFilter = null;
                ListFilter lFilter = null;

                this.Columns.Sort(new Comparison<FundScreenerReportColumn>(SortByOrder));
                grid.ColumnModel.Columns.Clear();
                grid.Plugins.Clear();
                //create Grid Filter
                GridFilters f = new GridFilters();
                grid.Plugins.Add(f); 
                foreach (FundScreenerReportColumn c in this.Columns)
                {
                    col = new Column();
                    col.ColumnID = c.ColumnName;
                    col.Header = c.ColumnName;

                    col.Sortable = true;

                    if (c.DataType.Contains("date"))
                    {
                        col.Renderer.Fn = string.Format("Ext.util.Format.dateRenderer('{0}')", c.DisplayFormat);
                    }
                    if (c.DataType.Contains("float"))
                    {
                        col.Renderer.Fn = string.Format("Ext.util.Format.numberRenderer('{0}')", c.DisplayFormat);
                    }
                    if (c.ColumnName.ToLower().Contains("icon"))
                        col.Renderer.Fn = "getImage";

                    col.DataIndex = c.ColumnName;

                    grid.ColumnModel.Columns.Add(col); 
             


                    //add appropriate filter
                    if (c.FilterGrid.Equals("Numeric"))
                    {
                        nFilter = new NumericFilter();
                        nFilter.DataIndex = c.ColumnName;
                        f.Filters.Add(nFilter);
                    }
                    else if (c.FilterGrid.Equals("List"))
                    {
                        lFilter = new ListFilter();
                        lFilter.DataIndex = c.ColumnName;
                        lFilter.Options = c.FilterGridValues.Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries);
                        f.Filters.Add(lFilter);
                    }
                    else
                    {
                        sFilter = new StringFilter();
                        sFilter.SetActive(true);
                        sFilter.AutoDataBind = true;
                        sFilter.DataIndex = c.ColumnName;
                        f.Filters.Add(sFilter);
                    }
                  

                }

               
                grid.Reconfigure();
                // DataSet ds = rpt.GetData(false);

                store.DataSource = this.GetData(testData);
                store.DataBind();
                //this.GridPanel1.Title = rpt.ReportName;
                grid.DataBind();
                if (Ext.IsAjaxRequest)
                    grid.RefreshView();
            }
            catch (Exception er)
            {
                Utilities.NotificationError(er.ToString());
            }
        }

Here is the Grid and Store Definitions..

        <ColumnModel ID="ColumnModel1" runat="server">
            <Columns>
            </Columns>

            </ext:GroupingView>
        </View>
        <Plugins>
            
        </Plugins>

            <ext:PagingToolbar ID="PagingToolBar1" runat="server" StoreID="Store1" PageSize="50" DisplayInfo="true" DisplayMsg="Displaying Results {0} - {1} of {2}">

                        <Listeners>
                            <Click Handler="#{GridPanel1}.getView().toggleAllGroups();" />
                        </Listeners>
                    </ext:ToolbarButton>

        <Listeners>     
                <BeforeUpdate Handler="#{maskDiv}.removeClass('x-hide-display');" />
                <Update Handler="#{maskDiv}.addClass('x-hide-display');" />  
        </Listeners>
    </ext:GridPanel>

Maybe a little late in the reply, but...

You need to bind the column with the DataIndex...
col = new Column();
col.DataIndex = c.ColumnName;
col.ColumnID = c.ColumnName;
col.Header = c.ColumnName;

Hope this helps.
