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
