  • Problem with cellsRenderer property #63492

    Hi,

    My Tree Grid turned slow to load when I use the cellsRenderer property to return a HTML content, when the content is removed the tree grid loads pretty better. Please help.

    ` cellsRenderer: function (rowKey, dataField, value, data) {
    //debugger;
    if (data.level == 0) {
    var DisplayHTML = “” +
    “<div class=’ActivityMenu’>

      ” +

    • v” +
      “<ul Group='” + dataField + “‘ RowKey = ” + rowKey + “> <li ElemId=’COPY’>Copy Value
    • <li ElemId=’PASTE’>Paste Value <li ElemId=’UPCURR’ style=’color:grey’>Upload All Values <li ElemId=’UPUPD’ style=’color:grey’>Upload Selected Values <li ElemId=’SAVE’>Save <li ElemId=’RESET’>Reset to default

    ” +
    “</div>”;
    return DisplayHTML;
    }
    else {
    return value;
    }

    Hi Sairam,

    If you do something which slows down the widget within the cellsRenderer, you’ll slow it down. I would suggest you to avoid doing much calculations within a function which is called for each cell.

    Hi Sairam,

    I don’t see a problem and why that will affect the performance then. I think that it won’t because it does not matter whether cellsRenderer is used or not unless you do something in the cellsRenderer which slows down the things.
