Set filter programatically?

[Bob]

Hi, I want to set a default filter value for a column on the grid but only if the application is not already persisting state.  My question is how do I set a filter programmatically in this scenario?  There is a Boolean column called "Enabled" that I am trying to default to TRUE when no pervious grid state can be found on client.

var localStorageKey = "UserAdministrationUserGridOptions";

$(function () {
    // pull client grid state and apply to grid (filters, current page, sorts, etc).
    setGridOptions();
});

function setGridOptions() {
    var options = localStorage[localStorageKey];

    if (options) {
        $("#UserAdministrationUserGrid").data("kendoGrid").setOptions(JSON.parse(options));
    }
    else
    {
    // set initial enabled filter to true
   // HOW DO I DO THIS IN JAVASCRIPT
    // server: .Filter(f => f.Add(m=> m.Enabled).IsEqualTo(true))
    }
}

If anyone is interested, here's my resolution:

function setGridOptions()
{
    var options = localStorage[localStorageKey];
    var grid = $("#UserAdministrationUserGrid").data("kendoGrid");

    // if user has saved options, then load them up
    // else, load grid with "enabled only" filter
    if (options) {
        grid.setOptions(JSON.parse(options));
    }
    else
    {
        grid.dataSource.filter({
            field: "Enabled",
            operator: "eq",
            value: true
        });
    }
}

Hello Bob,

 

The dataSource filter method is the recommended way to go.

 

Thanks for sharing your solution.
