问题 When invoking destroy() in KendoUI Grid and then recreate the table on a new DataSource : why do the old table columns still exist? The only element here that stays the say is the element. How do I tell the grid to read the new datasource columns (it reads everything else correct). (if I make 2 different elements, they both populate properly but I rather just keep 1 element and replace the elements table by destroy and reinit) 回答1: Most probably this is because you are not clearing the

问题 I am using the JSON2 library in order to use JSON.stringify to send some JSON data to my MVC controller. When I include another script in my view (Telerik MVC) I start to get script conflicts when using IE7. When I click the refresh button in the grid, I get the following error: Line: 191 Error: Object doesn't support this property or method String.prototype.toJSON = Number.prototype.toJSON = Boolean.prototype.toJSON = function (key) { return this.valueOf(); }; The error occurs on the

问题 Thanks for visiting. I am having trouble refreshing a Telerik grid when the Refresh button is clicked. In other words, if the user changes the data and decides not to save it, clicking the refresh button should reload the grid with the original values. Here is my XAML in the View for the Refresh: <Button Content="Refresh" Grid.Row="1" Margin="92,5,0,11" Command="{x:Bind ViewModel.RefreshDataCommand}"/> Here is my XAML in the View for the Grid: <tg:RadDataGrid ColumnDataOperationsMode="Flyout"

问题 I am using a kendo grid with multiple columns. But i need to display few columns with red asterick to indicate required filed. Can someone help me on this. <div id="failureTypeInfoGrid" style="width:100%;overflow-x:auto;"> @(Html.Kendo().Grid(Model.lstSerialData) .Name("serialGrid") .Events(e => e.Edit("onEdit")) .Columns(columns => { columns.Bound(c => c.UnitId).Hidden(true).ClientTemplate("#= UnitId #" + "<input type='hidden' name='SerialData[#= index(data)#].UnitId' value='#= UnitId #' />"

问题 I have this code I found but it doesnt work even after i tried many conversions. Basically it converts smartly a Datatable into a List that can be serializable. The error is that it can't convert a Dictionary<string, object> to a List<object> : public GridBindingData GetSomething() { DataTable dt = GetDatatable(); var columns = dt.Columns.Cast<System.Data.DataColumn>(); var data = dt.AsEnumerable() .Select(r => columns.Select(c => new { Column = c.ColumnName, Value = r[c] }) .ToDictionary(i =

问题 I have a DateTime field bound to a grid. When the grid enters edit mode the date/time picker displays, but the value is cleared from it. This forces the user to re enter the date/time. Any idea why it value is cleared when the edit mode is triggered? @(Html.Telerik().Grid<ExpenseGridModel>() .DataBinding(dataBinding => dataBinding.Ajax() .Select("ExpenseAjaxBinding", "ExpenseEntry") .Update("ExpenseUpdate", "ExpenseEntry") ) .Name("ExpensesGrid") .DataKeys(keys => keys.Add(r => r.id))

问题 I'd prefer for either string or int but would settle for it based on bit. The Goal is if the value of a String field == 'blah blah blah' that it will turn that whole row grey(blue table with red and green already used on it so I'm open to any other colour suggestion) I've tried .RowAction(row => { if (row.DataItem.[Bound Data col Name] == "[String value]") { row.HtmlAttributes["style"] = "background:grey;"; } }) and .RowAction(row => { if (row.DataItem.[Bound Data col Name] == "[String value]

问题 I have a Telerik grid populated by an Ajax command similar to the following: PowerStatusGrid.cshtml @{Html.Telerik().Grid(Model) .Name("PowerStatusGrid") .DataKeys(k => k.Add(o => o.StatusItemId)) .Columns(columns => { columns.Bound(o => o.ItemName).Title("Name").Width(250).ReadOnly(true); columns.Bound(o => o.DateTimePicker).Title("Date/Time").Width(150); columns.Command(commands => { commands.Edit().ButtonType(GridButtonType.BareImage).HtmlAttributes(new { @class = "grid-edit-button" })
