ContextMenu with nested grid

[David]

Hi,

Is it possible to attach a context menu to a nested grid ? I currently have a radGrid with a nestedGrid and I use the following code to attach a menuContext

function RowContextMenu(sender, eventArgs) {

    var menu;

    var ownerTable = eventArgs.get_tableView();

 

    if (ownerTable.get_name() == "Grid") {

        menu = $find("<%=RadContextMenuUser.ClientID %>");

    }

    else if (ownerTable.get_name() == "NestedGrid") {

        menu = $find("<%=RadContextMenuUsersRole.ClientID %>");

    }



    var evt = eventArgs.get_domEvent();

 

    if (evt.target.tagName == "INPUT" || evt.target.tagName == "A") {

    return;

    }

 

    var index = eventArgs.get_itemIndexHierarchical();

    document.getElementById("radGridClickedRowIndex").value = index; 

    document.getElementById("radGridClickedTableId").value = ownerTable._data.UniqueID;

 

    sender.get_masterTableView().selectItem(sender.get_masterTableView().get_dataItems()[index].get_element(), true);

For the "parent" grid, it works really great, but it doesn't work for the nestedGrid. In fact, I have the following error : 
Cannot call method 'get_element' of undefined.  

So, anyone may help me please ?

Hi,

Finally, try this and it work :

var gridIndex = index.split(":", 1);
index = index.split("_");
sender.get_masterTableView().selectItem(sender.get_detailTables()[gridIndex].get_dataItems()[index[1]].get_element(), true);

Edit : In fact, it seem it doesn't work that  well. In fact, in will explain again my problem, cause I realized I really wasn't clear. What I want is, when I right click on a item on the nested grid (or detail table), the item become selected and a context menu pop up. I know how to attach the context menu to the item of the nested grid, but I don't quite know how to selected this item. The code I put in this post doesn't work well, cause it doesn't un-select the previous selected item. So, my nested grid, even if AllowMultiRowSelection is set to false, allow to selected many item by this way. So, may someone help me please.

Hello David,

You can clear the selected items before selecting a new one. I confirm it is possible to select more than one item via the client-side API.

var masterTable = $find('<%= RadGrid1.ClientID %>').get_masterTableView();
masterTable.clearSelectedItems();

Kind regards,

Thank you, it work.

But, in fact, it wasn't get_masterTableView(), but get_detailTables().
