    [CLOSED] Grid Tooltip with Renderer


    I've got a row tooltip no problem following the example but I'd like to pull the active GridView text for a particular row cell, as it has a Renderer in place - I need the rendered value.

    ie: I hover over a row, and one of my columns has a renderer on it with a text value which I'd like to show in my tooltip.

    My tooltip code:

                            <ext:ToolTip ID="RowTip" runat="server" Target="={#{listActionEventLog}.getView().mainBody}"
                                Delegate=".x-grid3-row" TrackMouse="true">
                                    <Show Handler="this.body.dom.innerHTML = setupEventTooltip(this.triggerElement);" />
    var setupEventTooltip = function (index) {
        var rowIndex = listActionEventLog.view.findRowIndex(index);
        var record = listActionEventLog.getStore().getAt(rowIndex);
         return "<b>Changes by {0}</b><br />{1}".format(record.get("ModifiedById"), record.get("ChangeLog"));

    This uses the stores though so I'm getting the ID rather than the username showing up for my 'ModifiedById'. I'd rather not have to call the renderer manually again, as the grid already shows the name in the cell.

    Hi Peter,

    You can get an HTML element of a specified cell.

    <%@ Page Language="C#" %>
    <%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
    <script runat="server">
        protected void Page_Load(object sender, EventArgs e)
            if (!X.IsAjaxRequest)
                Store store = this.GridPanel1.GetStore();
                store.DataSource = new object[] 
                    new object[] { "test1" },
                    new object[] { "test2" },
                    new object[] { "test3" }

                var view = grid.getView(),
                    rowIndex = view.findRowIndex(toolTip.triggerElement),
                    cell = view.getCell(rowIndex, grid.getColumnModel().findColumnIndex("test"));
                toolTip.body.dom.innerHTML = cell.childNodes[0].innerHTML;
        <form runat="server">

                            <Renderer Handler="return '<b>' + value + '</b>';" />
                    <Show Handler="onShow(this, #{GridPanel1});" />
