Open add/edit dialog dynamically

7 Jan 20231 minute to read

Gantt add and edit dialogs can be opened dynamically by using openAddDialog and openEditDialog methods. The following code example shows how to open add and dialog on separate button click actions.

CSHTML

@Html.EJS().Button("editDialog").Content("Open Edit Dialog").CssClass("e-primary").Render()
    @Html.EJS().Button("addDialog").Content("Open Add Dialog").CssClass("e-primary").Render()
    @Html.EJS().Gantt("Gantt").DataSource((IEnumerable<object>)ViewBag.DataSource).Height("450px").TaskFields(ts => ts.Id("TaskId").Name(
        "TaskName").StartDate("StartDate").EndDate("EndDate").Duration("Duration").Progress("Progress").Child("SubTasks")).EditSettings(es =>
         es.AllowEditing(true).AllowAdding(true)).Render()
        
	<script>
        document.getElementById('editDialog').addEventListener('click', function (args) {
            var ganttObj = document.getElementById('Gantt').ej2_instances[0];
            ganttObj.editModule.dialogModule.openEditDialog();
        });

        document.getElementById('addDialog').addEventListener('click', function (args) {
            var ganttObj = document.getElementById('Gantt').ej2_instances[0];
            ganttObj.editModule.dialogModule.openAddDialog();
        });
	</script>

OpenEditAddDialog.cs

public IActionResult Index()
{
    ViewBag.DataSource = GanttData.ProjectNewData();
    return View();
}

NOTE

We should select any one of the row in Gantt to open the edit dialog.
