Save State

function GetDataGrid() {
    var grid = $("#GridCustomers").data("kendoGrid");
    var dataSource = grid.dataSource;
    var currentColumnState = new Array();

    for (var i = 0; i < grid.columns.length; i++) {

        if (grid.columns[i].hidden == undefined) {
            grid.columns[i].hidden = false;
            currentColumnState.push({
                field: grid.columns[i].field,
                hidden: grid.columns[i].hidden
            });
        }
        else {
            currentColumnState.push({
                field: grid.columns[i].field,
                hidden: grid.columns[i].hidden
            });
        }
    }

    var state = {
        page: dataSource.page(),
        pageSize: dataSource.pageSize(),
        sort: dataSource.sort(),
        group: dataSource.group(),
        filter: dataSource.filter(),
        columns: currentColumnState
    };

    return JSON.stringify(state);
}

Load State

function SetDataGrid(data) {
            debugger;
            var result = data.result;
            var jsonResult = $.parseJSON(result);

            var state = $.parseJSON(jsonResult.Data);

            var grid = $("#GridCustomers").data("kendoGrid");
            var options = grid.options;

            for (var i = 0; i < state.columns.length; i++) {
                options.columns[i].hidden = state.columns[i].hidden;
                console.log(state.columns[i]);
                if (state.columns[i].hidden == true) {
                    grid.hideColumn(i);
                }
                else {
                    grid.showColumn(i);
                }
            }

            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();
            $("#GridCustomers").kendoGrid(options);
        }

 

Thanks All

Hello,

I would suggest you to take a look at the Grid Persist state demo, which shows how getOptions and setOptions client-side methods should be used, to persist all Grid options.

Feel free to contact us again, if you have any questions.
