Hi,

I am trying to show/hide the filter row on the grids initial load.  I have the following script set and based on the alert messages the code is running correctly but the filter row isn't being displayed when it should be.



Can you tell me what I am missing.

Thanks for you assistance.

Tracy
function GridInitialLoad(sender, eventArgs) {
    
    var masterTable = sender.get_masterTableView();
    var rbtFilter = $telerik.findControl(sender.get_element(), "rbtFilters");
    var i = 0;
    var result;
    var toggleList;
     
    if (rbtFilter) {
        toggleList = rbtFilter.get_selectedToggleStateIndex();
        switch (toggleList) {
            case 0:
                rbtFilter.set_toolTip('Show Filter Row');
                masterTable.hideFilterItem();
                alert('hide');
                break;
            case 1:
                rbtFilter.set_toolTip('Hide Filter Row');
                masterTable.showFilterItem();
                alert('show');
                break;
        }
         
    }
 
    var rbtGroup = $telerik.findControl(sender.get_element(), "rbtGrouping");
    if (rbtGroup) {
        toggleList = rbtGroup.get_selectedToggleStateIndex();
        switch (toggleList) {
            case 0:
                rbtGroup.set_toolTip('Show Group Panel');
                result = $telerik.$(".rgGroupPanel");
                for (i = 0; i < result.length; i++) {
                    result[i].className = "hideGroupPanel";
                }
                break;
            case 1:
                rbtGroup.set_toolTip('Hide Group Panel');
                result = $telerik.$(".hideGroupPanel");
                for (i = 0; i < result.length; i++) {
                    result[i].className = "rgGroupPanel";
                }
                break;
        }
    }

Hello Tracy,

In a scenario where the filter item should be shown is it being first hidden on the server? Note that if this is the case a filter item will not be rendered at all and it is expected for the client-side logic to not display it. If you follow such an approach I recommend removing the server-side logic and only hiding the filter item on the client when necessary.

If the issue persist after modifying the logic according to the above please share with us the entire page contents so we could examine the implementation and advice you further.
