Hello,

I’ve modified my sample by adding WebGrid’s OnColumnContextMenu client side event.
On that event, I hide all menu item except “Select Column” menu item.
Here’s the snippet OnColumnContextMenu client side event:

function WebGrid1_OnColumnContextMenu(controlId, col, menu, isGroup, location) {
    var WebGrid1 = ISGetObject(controlId);
    var menuItemLength = menu.Items.length;

    for (var i = 0; i < menuItemLength; i++) {
        var menuItemName = menu.Items[i].Name;
        if (menuItemName != "mnuSelectColumns") {
            menu.Items[i].Hide();
        }
    }
    return true;
}

I attached the modified sample as well.

Thank you.
Regards,
Hans.

Hello,

You could show the context menu of column header through button click by using ShowContextMenu() function.
To use ShowContextMenu() function, you should get the column object first.
I’ve made a sample that maybe similar with your current scenario.  I use WebGrid (bind to Northwind.mdb and Shippers table) and WebButton in my sample.
Then I use OnClientClick client side event of WebButton, to show the context menu.
Here’s the snippet code in OnClientClick:

<script language="javascript" type="text/javascript" id="WebButton1_OnClientClick">
	function WebButton1_OnClientClick(controlId, parameter) {
        var WebButton1 = ISGetObject(controlId);
        var WebGrid1 = ISGetObject("WebGrid1");
        // Show context menu for ShipperID column
        WebGrid1.RootTable.Columns.GetNamedItem("ShipperID").ShowContextMenu();
        return true;
    }
</script>

I attached my sample as well, in order to make you easier understand about my sample.

Hope this helps. Thank you.

Hello,

Yes it is possible to run your scenario.
I suggest you to modify the item in export context menu with new menu item.
And set the menu item’s event as you please.

You could modify the export context menu item in OnExportContextMenu client side event of WebGrid.
Here’s the example snippet code that perhaps you could use.

function WebGrid1_OnExportContextMenu(controlId, table, menu, location) {
    var WebGrid1 = ISGetObject(controlId);
            
    // Clear all default Export Context Menu
    menu.ClearAll();

    // Create new menu item
    var menuItem = new WebMenuItem();
    menuItem.Text = "My Menu Item";
    menuItem.Name = "MyMenu";
    menuItem.OnClick = "NewFile";

    // Add Menu Item    
    menu.Items.Add(menuItem);

    return true;
}

function NewFile() {
    alert("Your new file");
}

I attached the example sample, that implement customize export context menu, as well.

Hope this helps. Thank you.

Hello

I’m sorry, but unfortunately I can’t find way to determine if this was a double or single click, in one event function.
However, I have solution for your problem that maybe you could use.
I made a sample project by using WebGrid (Nortwind.mdb database & Shippers table).
I use WebGrid’s OnCellClick and OnCellDblClick client side event.
In OnCellClick event, I use setTimeout function to determine if this was a double or single click.
Here’s the snippet code:

<script language="javascript" type="text/javascript">
    var double = false;

    function WebGrid1_OnCellClick(controlId, tblName, rowIndex, cellIndex, cellEl) {
        var WebGrid1 = ISGetObject(controlId);
        window.setTimeout(function () {
            if (double == false) {
                alert("Single Click");
            }
            else {
                double = false;
            }
        }, 500)
        return true;
    }

    function WebGrid1_OnCellDblClick(controlId, tblName, rowIndex, cellIndex, cellEl) {
        var WebGrid1 = ISGetObject(controlId);
        alert("Double Click");
        double = true;
        return true;
    }
</script>

I attached my sample project, in order to make you easily understand about my sample.

And please let me know if this solution can resolve your problem or not. Perhaps, I can find another way to resolve your problem.

Thank you.
