Hi Neil,
Thanks for using Syncfusion products.
Query 1:
Can you tell me what type of object this is and how i can extract the selected rows information from it?
Solution:
We would like to let you know that, “args” parameter, which is passed to the “ContextMenuOpen” client side event is a JSON object. It holds the details of the selected rows, list of context menu items and their corresponding sub context menu items. Please check the following details for the list of items available in the “args” parameter.
|
ARGS |
Action |
|
contextMenuItems |
List of context menu items |
|
index |
Index of the selected row |
|
innerContextMenuItems |
List of sub context menu items corresponding to the main context menu items. |
|
item |
Details of the selected rows |
|
model |
TreeGrid object |
|
targetElement |
Html elements of the clicked row |
Please find the below code snippets for rendering custom context menu in TreeGrid.
Code snippets:
|
<body style="position: static; margin: 0px; padding: 2px">
@(Html.EJ().TreeGrid("Tree")
//...
.ContextMenuSettings(cms => cms.ShowContextMenu(true)
.ContextMenuItems(new List<TreeGridContextMenuItems>()
{
TreeGridContextMenuItems.Add,
TreeGridContextMenuItems.Edit,
TreeGridContextMenuItems.Delete
}))
.ContextMenuOpen("customMenu")
.Datasource((System.Collections.IEnumerable)ViewBag.datasource)
)
@(Html.EJ().ScriptManager())
<script>
function customMenu(args) {
args.contextMenuItems.push({
headerText: "Menu_1",
iconPath: 'url("../../Images/setIcon.png")',
eventHandler: customMenuClick1,
})
args.contextMenuItems.push({
headerText: "Menu_2",
iconPath: 'url("../../Images/setIcon.png")',
eventHandler: customMenuClick2,
})
}
function customMenuClick1(args) {
alert("Custom Menu 1 clicked");
}
function customMenuClick2(args) {
alert("Custom Menu 2 clicked");
}
</script>
</body>

Query 2:
Do you have any reference documents at all for your controls, since your documentation is very basic?
Solution:
We request you to refer the below online link for the reference documents related to the properties of all Syncfusion controls.
