How do I apply a filter on a grid using javascript?

[Christine Romano]

I am creating the following grid.

@(Html.EJ().Grid<MerchantsViewModel>("MerchantsGrid"

).Datasource((IEnumberable<object>)Model.Merchants)

.FilterSettings(filter => { filter.ShowFilterBarStatus().StatusBarWidth(500).FilterType(FilterType.Excel).FilterBarMode(FilterBarMode

.Immediate); })

.Columns(col =>

{

col.Field("Email").HeaderText("Email(s)").Width(120).Add();

.

.

.

And I want to filter (based on an event). How would I filter on my grid data to display only the data that has [e-mail] in the Email field? 

function applyFilter(filterValue) {

var stringValue = filterValue == "All" ? "" : filterValue;

var gridObj = $("#MerchantsGrid").ejGrid("instance");

var filteredActiveData = ej.DataManager(gridObj).executeLocal(ej.Query().where("Email", ej.FilterOperators.contains, "[e-mail]", false));

}

}

Hi Christine,

Thanks for using Syncfusion products.

We have analyzed the provided code snippet and suspect that you have passed the grid object directly to the ej.DataManager (“ as ej.DataManager(gridObj).”) instead of passing the grid datasource and hence the data was not filtered correctly.

We can filter the Email field with value “[e-mail]” from grid datasource as follows.

function applyFilter(filterValue) {

var stringValue = filterValue == "All" ? "" : filterValue;

var gridObj = $("#MerchantsGrid").ejGrid("instance");

var filteredActiveData = ej.DataManager(gridObj.model.dataSource).executeLocal(ej.Query().where("Email", ej.FilterOperators.contains, "[e-mail]", false));

}

Now in the above highlighted section, you can see that we have passed the grid datasource to ej.DataManager and now filteredActiveData will contain the filtered value.

If you want to display the filtered value in grid, then we can do as follows.

gridObj.dataSource(filteredActiveData)
