How to customize the dialog fields of Gantt

Platform: ASP.NET Web Forms |
Control: Gantt |
Published Date: July 31, 2017 |
Last Revised Date: May 28, 2019

In Gantt control, user can enable or disable required fields in both edit dialog box and add dialog box for all the predefined columns and custom columns with the help of “EditDialogFields” and “AddDialogFields” property. The provided fields in the “EditDialogFields” and “AddDialogFields” property alone will be displayed in the dialog box of the Gantt chart.

Please refer the following code snippets for more details.

Code snippets:

ASP

<body>
<form id="form1" runat="server"  
//...
<ej:Gantt ID="Gantt" runat="server"  
//...
Load="Load">            
<AddDialogFields>
<ej:AddDialogField Field="Id" />
<ej:AddDialogField Field="Name" />
<ej:AddDialogField Field="StartDate" />
<ej:AddDialogField Field="Duration" />
</AddDialogFields>
 
<EditDialogFields>
<ej:EditDialogField Field="Name" />
<ej:EditDialogField Field="StartDate" />
<ej:EditDialogField Field="ExpectedDate" /> <%--To display custom column--%>
</EditDialogFields>
</ej:Gantt>
<script>
function Load(args) {
var columns = this.getColumns();
columns.splice(2, 0,
{
field: "ExpectedDate",
headerText: "Expected Date ",
editType: "stringedit",
mappingName: "ExpectedDate", //Provide this mapping name
width: "180px"
});            
}
</script>
