How to bind TimeSpan value to Grid column in ASP.NET WebForms?
We cannot bind the Timespan value directly to the grid columns. This is a known limitation due to the fact that there is no Timespan datatype in Javascript. Also the .Net JavascriptSerailizer will serializes the TimeSpan object to Complex object, and hence trying to bind the Timespan value directly in grid columns will display the column value as [object Object].
In such cases, we can use the Column template feature of the grid to display the TimeSpan values in desired format.
For example we can use the following Jsrender custom converter to format the timespan value.
<script type="text/javascript">
$.views.converters("value", function (val) {
return Globalize.format(val, "D2");
});
</script>
In the following code snippets, we have demonstrated, how to use the column template to display the timespan value in grid.
Grid Initialization
JS
<div id="Grid"></div>
<script type="text/javascript">
$("#Grid").ejGrid({
dataSource: ej.DataManager({ url:"Home/GetEmployee", adaptor:"UrlAdaptor" }),
allowPaging: true,
columns: [
{ field: "EmployeeID", headerText: 'Employee ID' },
{ field: "FirstName", headerText: 'First Name'},
{ field: "LastName", headerText: 'Last Name'},
{ headerText: 'Worked Hours', template: "{{value:WorkedHours.Hours}} : {{value:WorkedHours.Minutes}} : {{value:WorkedHours.Seconds}}" },
]
});
</script>
MVC
@(Html.EJ().Grid<object>("Grid")
.Datasource(ds => ds.Url("Home/GetEmployee").Adaptor(AdaptorType.UrlAdaptor))
.AllowPaging()
.Columns(col =>
{
col.Field("EmployeeID").HeaderText("Employee ID").Add();
col.Field("FirstName").HeaderText("First Name").Add();
col.Field("LasttName").HeaderText("Last Name").Add();
col.HeaderText("Worked Hours").Template("{{value:WorkedHours.Hours}} : {{value:WorkedHours.Minutes}} : {{value:WorkedHours.Seconds}}").Add();
}))
ASPX
<ej:Grid ID="Grid" runat="server" AllowPaging="true">
<DataManager URL="Default.aspx/GetEmployee" Adaptor="UrlAdaptor" />
<Columns>
<ej:Column Field="EmployeeID" HeaderText="Employee ID"/>
<ej:Column Field="FirstName" HeaderText="First Name"/>
<ej:Column Field="LastName" HeaderText="Last Name"/>
<ej:Column HeaderText="Worked Hours" Template="{{value:WorkedHours.Hours}} : {{ value:WorkedHours.Minutes}} : {{value:WorkedHours.Seconds}}"/>
</Columns>
</ej:Grid>
The grid data has been returned from the below function.
public IEnumerable<Employee> GetEmployee()
{
return new List<Employee>() {
new Employee(){ EmployeeID=1, FirstName="Gatsby", LastName="Great", WorkedHours= TimeSpan.Zero},
new Employee(){ EmployeeID=2, FirstName="Rock", LastName="John", WorkedHours= TimeSpan.FromHours(9)},
new Employee(){ EmployeeID=3, FirstName="Greak", LastName="Sena", WorkedHours= TimeSpan.FromHours(7)},
new Employee(){ EmployeeID=4, FirstName="Bolt", LastName="Remo", WorkedHours= TimeSpan.FromHours(6)},
new Employee(){ EmployeeID=5, FirstName="Alan", LastName="Sangeth", WorkedHours= TimeSpan.FromHours(5)},
new Employee(){ EmployeeID=6, FirstName="Linga", LastName="Lee", WorkedHours= TimeSpan.FromHours(4)},
new Employee(){ EmployeeID=7, FirstName="Frok", LastName="Reck", WorkedHours= TimeSpan.FromHours(3)},
};
}
The output will be as follows.
