Hi,

I'm using a grid wich keep state without problem
My only problem is that when the grid is rebuild, my toolbar ( export to excell ) has disapeard.

@(Html.Kendo().Grid<UserCustomizedViewModel>()
.Name("grid")
.DataSource(dataSource => dataSource
.Ajax()
.Aggregates(aggregates =>
{
aggregates.Add(p => p.Origin_Code).Count();
})
.Read(read => read.Action("UserCustomizedRead", "Rdr")
.Data("asco.rdrReadData"))
.Model(model => model.Id(rdr => rdr.Id))
.PageSize(50)
.Sort(sort => sort.Add(model => model.RdrNumber).Descending())
.Events(events =>
{
events.Error("onGridDataSourceError");
events.Change("onGridDataSourceChange");
}))
.Events(events => events.DataBound("onGridDataBound"))
.Columns(columns =>
{
columns.Bound(model => model.Origin_Code)
.Title(Global.ColumnOrigin)
.ClientTemplate("<span class='tooltips' data-placement='top' title='#= Origin_Value_English #'>#= Origin_Code # </span>")
.Visible(currentCulture == Cultures.En)
.Width(20)
.ClientGroupFooterTemplate("Count: #=count#");
columns.Bound(model => model.Origin_Code)
.Title(Global.ColumnOrigin)
.ClientTemplate("<span class='tooltips' data-placement='top' title='#= Origin_Value_French #'>#= Origin_Code # </span>")
.Visible(currentCulture == Cultures.Fr)
.Width(20)
.ClientGroupFooterTemplate("Count: #=count#");
columns.Bound(model => model.Origin_Code)
.Title(Global.ColumnOrigin)
.ClientTemplate("<span class='tooltips' data-placement='top' title='#= Origin_Value_German #'>#= Origin_Code # </span>")
.Visible(currentCulture == Cultures.De)
.Width(20)
.ClientGroupFooterTemplate("Count: #=count#");
columns.Bound(model => model.Origin_Code)
.Title(Global.ColumnOrigin)
.ClientTemplate("<span class='tooltips' data-placement='top' title='#= Origin_Value_Dutch #'>#= Origin_Code # </span>")
.Visible(currentCulture == Cultures.Nl)
.Width(20)
.ClientGroupFooterTemplate("Count: #=count#");
columns.Bound(model => model.RdrNumber)
.Title(Global.ColumnRdrNumber)
.ClientTemplate(Html.ActionLink("#= RdrNumber #", "Edit", new { id = "id" }).ToHtmlString().Replace("id", "#=Id#"))
.Width(70);
columns.Bound(model => model.RdrStatus_Value_English)
.Title(Global.ColumnRdrStatusType)
.Visible(currentCulture == Cultures.En)
.Width(70);
columns.Bound(model => model.RdrStatus_Value_German)
.Title(Global.ColumnRdrStatusType)
.Visible(currentCulture == Cultures.De)
.Width(70);
columns.Bound(model => model.RdrStatus_Value_French)
.Title(Global.ColumnRdrStatusType)
.Visible(currentCulture == Cultures.Fr)
.Width(70);
columns.Bound(model => model.RdrStatus_Value_Dutch)
.Title(Global.ColumnRdrStatusType)
.Visible(currentCulture == Cultures.Nl)
.Width(70);
columns.Bound(model => model.CreatedOn)
.Title(Global.ColumnCreatedOn)
.Format("{0:dd/MM/yyyy}")
.Width(100);
columns.Bound(model => model.CreatedByText)
.Title(Global.ColumnCreatedBy)
.Width(150);

})
.ToolBar(tools => tools.Excel())
.Excel(excel => excel
.FileName("Kendo UI Grid Export.xlsx")
.Filterable(true)
.AllPages(true)
.ProxyURL(Url.Action("Excel_Export_Save", "Rdr"))
)
.Reorderable(r => r.Columns(true))
.Resizable(r => r.Columns(true))
.Groupable()
.ColumnMenu()
.Pageable(pager => pager
.Refresh(true)
.PageSizes(new[] { 50,100, 200, 500, 1000, 3000 })
.Messages(messages =>
{
messages.Refresh(Global.GridPagerClickToRefresh);
messages.ItemsPerPage(Global.GridPagerItemsPerPage);
messages.Of(Global.GridPagerOf);
messages.Next(Global.GridPagerNext);
messages.Last(Global.GridPagerLast);
messages.First(Global.GridPagerFirst);
messages.Previous(Global.GridPagerPrevious);
messages.Page(Global.GridPagerPage);
messages.Empty(Global.GridPagerEmpty);
messages.Display(Global.GridPagerDisplay);
}))
.Filterable(filter =>
{
filter.Extra(true);
filter.Messages(messages =>
{
messages.And(Global.GridFilterAnd);
messages.Clear(Global.GridFilterClear);
messages.Filter(Global.GridFilterFilter);
messages.Info(Global.GridFilterInfo);
messages.IsFalse(Global.GridFilterIsFalse);
messages.IsTrue(Global.GridFilterIsTrue);
messages.Or(Global.GridFilterOr);
messages.SelectValue(Global.GridFilterSelectedValue);
});
filter.Operators(oper => oper.ForString(messages =>
{
messages.Clear();
messages.IsEqualTo(Global.GridFilterIsEqualTo);
messages.Contains(Global.GridFilterContains);
messages.StartsWith(Global.GridFilterStartsWith);
}));
})
//.Sortable(sortable => sortable.AllowUnsort(false))
)

Here is the code that load the state of my grid

var grid = $("#grid").data("kendoGrid");
//var dataSource = grid.dataSource;
var url = $("#LoadGridState").data('request-url');
var GridName = $("#SaveGridState").data('gridname');
$.ajax({
url: url,
type: 'POST',
async: false,
//cache: false,
data: {
GridName: GridName
},
success: function (state) {
try{
state = JSON.parse(state);
var options = grid.options;
options.columns = state.columns;
options.dataSource.page = state.page;
options.dataSource.pageSize = state.pageSize;
options.dataSource.sort = state.sort;
options.dataSource.filter = state.filter;
options.dataSource.group = state.group;
grid.destroy();
$("#grid")
.empty()
.kendoGrid(options);

}
catch (e) {
}

},
error: function (request, status, errorThrown) {
window.alerts.error(errorThrown);
}
});

thanks for your help

Hello Michel,

A more appropriate way to set the Grid state will be by using the setOption method. As mentioned in the description of the setOptions method, when using the ASP.NET MVC wrappers, the Toolbar template is rendered on the server, thus it cannot be recreated on the client. A way to workaround this limitation by manually assigning the toolbar template prior the widget re-creation is demonstrated in this hot-to article/project. Here is the project for the article.
