RadGrid Filtering Problem

[Carlos Valdez]

Hi, 

    When i select a filter in the RadGrid send me an error here:

        Telerik.Web.UI.GridTableView.registerClass(

"Telerik.Web.UI.GridTableView",Sys.UI.Control);

 

        Telerik.Web.UI.GridFilterFunction=

function(){};

 

        Telerik.Web.UI.GridFilterFunction.prototype= {NoFilter:0,Contains:1,DoesNotContain:2,StartsWith:3,EndsWith:4,EqualTo:5,NotEqualTo:6,GreaterThan:7,LessThan:8,GreaterThanOrEqualTo:9,LessThanOrEqualTo:10,Between:11,NotBetween:12,IsEmpty:13,NotIsEmpty:14,IsNull:15,NotIsNull:16,Custom:17};

        Telerik.Web.UI.GridFilterFunction.registerEnum(

"Telerik.Web.UI.GridFilterFunction",false);

 

        Telerik.Web.UI.GridFilterFunction.parse=

function(b,a){return(typeof b=="number")?b:Sys$Enum$parse.call(this,b,!!a);

    Sys$Enum$parse is not defined

thank you for your help.

Hello Carlos,

I suspect that you are using RadControls in .net 4.0 as target framework with ToolkitScriptManager from 4.0 branch of AjaxToolkit controls. If this is the case you can try latest version of RadControls for ASP.NET AJAX where this issue has been resolved.

Hi Nikolay,
I've proplem same as Calos Valdez about filter in RadGrid. I using lastest version RadControls and working .net 3.5.
I run demo project then it still working. But I add my project then doesnt not work and generate script error:
Sys$Enum$parse is not defined
.....
Telerik.Web.UI.GridFilterFunction.registerEnum("Telerik.Web.UI.GridFilterFunction",false);

Telerik.Web.UI.GridFilterFunction.parse=function(b,a){return(typeof b=="number")?b:Sys$Enum$parse.call(this,b,!!a);

...

I've add ScripManager in Master Page
In file xxx.aspx I've add RadAjaxManager

This is in file xxx.aspx:

  public void InstantiateIn(Control container)
        {
RadGrid radGrid = new RadGrid();
            radGrid.ID = name + "rda";
            radGrid.AllowFilteringByColumn = true;
            radGrid.AllowSorting = true;
            radGrid.GroupingSettings.CaseSensitive = false;
            radGrid.ClientSettings.EnableRowHoverStyle = true;
            radGrid.NeedDataSource += new GridNeedDataSourceEventHandler(radGrid_NeedDataSource);
            radGrid.PreRender += new EventHandler(radGrid_PreRender);
            //---
            radGrid.MasterTableView.AutoGenerateColumns = false;
            radGrid.MasterTableView.Columns.Clear();
           foreach (Column col in columns)
            {
                //columnNameNoLang = col.Name.Replace("@LANG", basePage.Lang);
                GridBoundColumn templateColumn = new GridBoundColumn();
                templateColumn.DataField = col.Name;
                switch (basePage.Lang)
                {
                 
                    case "en":
                        templateColumn.HeaderText = col.Caption_en;
                        break;
                   case "it":
                        templateColumn.HeaderText = col.Caption_it;
                        break;
                    default:
                        templateColumn.HeaderText = col.Caption_en;
                        break;
                }
                templateColumn.Visible = col.Visible;
                templateColumn.AllowFiltering = true;
                templateColumn.ShowFilterIcon = false;
                templateColumn.AutoPostBackOnFilter = true;
                
                templateColumn.CurrentFilterFunction = GridKnownFunction.Contains;
                radGrid.MasterTableView.Columns.Add(templateColumn);
                radGrid.ClientSettings.ClientEvents.OnRowSelected = "RowSelected_" + name;
                radGrid.ClientSettings.Selecting.AllowRowSelect = true;
            }
            container.Controls.Add(radGrid);
}
void radGrid_PreRender(object sender, EventArgs e)
        {
            RadGrid grid = sender as RadGrid;
            grid.MasterTableView.AutoGenerateColumns = false;
        }
        void radGrid_NeedDataSource(object source, GridNeedDataSourceEventArgs e)
        {
            RadGrid grid = source as RadGrid;
            DataTable dt = CaseDal.GetDatafromQueryString(datasource);
            grid.DataSource = dt;
        }

 I hope that you recomment and fixed about error for me.

Thanks.

Hi nguyen,

Try creating the grid on Page_init in the xxx.aspx page as described below and see if it makes any difference:
