I suspect that the iFrameElement might be null which causing the button "Accept All Changes" keep appearing.

I modified the script into following:

var wgReviewChanges = (function ()
{
    var original_wgReviewChanges = wgReviewChanges;
    var gridId = ISGetObject("WebGrid1").Id;

    return function (gridId)
    {
        original_wgReviewChanges(gridId);

        window.setTimeout(function ()
        {
            var dlgReviewDivId = "dvWnd_Global_wnd" + gridId + "_dlgReview";
            var dlgReviewDivElement = document.getElementById(dlgReviewDivId);
            var iFrameElement = dlgReviewDivElement.getElementsByTagName("iframe")[0];
            var innerDoc = (iFrameElement.contentDocument) ? iFrameElement.contentDocument : iFrameElement.contentWindow.document;
            var acceptAllBtnElement = innerDoc.getElementById(gridId + "_btnAccept_f");

            acceptAllBtnElement.style.display = "none";
        }, 100);
    }
})();

I have checked that adding the above script after WebGrid tag will removes the Accept All Changes button.

Should you have different result, you can try to: set the time out to be longer; or debug the script.

I carefully check the reported problem by using Enterprise.aspx live sample of WebGrid on IE 11, Chrome 51, Firefox 47, and Opera 38 by using following step-by-step:

1. Open the sample in browser.
2. Apply a filter to the grid. For example: apply Germany to Country column.
3. Select a row and then right-click. Do any action, for example: select "Show Child Rows" from the context menu.

I was unable to reproduce the reported problem using the above details. Please feel free to let me know if you find anything that I might miss during my attempt to reproduce the problem.

I override wgReviewChanges method and use following snippet code in order to remove the "Accept All Changes" button.

*Note: wgReviewChanges(gridId) is the method that invoked when user click the "Review Pending Changes" button (in the right-side of WebGrid's status bar).

var wgReviewChanges = (function ()
{
    var original_wgReviewChanges = wgReviewChanges;
    var gridId = "WebGrid1";

    return function (gridId)
    {
        original_wgReviewChanges(gridId);
                        
        window.setTimeout(function ()
        {
            var dlgReviewDivId = "dvWnd_Global_wnd" + gridId + "_dlgReview";
            var dlgReviewDivElement = document.getElementById(dlgReviewDivId);
            var iFrameElement = dlgReviewDivElement.getElementsByTagName("iframe").wndWebGrid1_dlgReview;
            var innerDoc = (iFrameElement.contentDocument) ? iFrameElement.contentDocument : iFrameElement.contentWindow.document;
            var acceptAllBtnElement = innerDoc.getElementById(gridId + "_btnAccept_f");

            acceptAllBtnElement.style.display = "none";
        }, 100);
    }
})();

I enclosed a simple sample (as attachment) of batch update enabled WebGrid which implements the above script. Hope this helps.

Thank you for the detail information.

The reported problem is reproducible in my local end. It has been forwarded to the development team. The report is filed under ASPNET-398.

I'll let you know when the nightly build or hotfix is ready to be evaluated on your end.

Based on the conversation through our live chat service, following feature in WebCombo has been enabled:

• multiple selection: WebCombo > MultipleSelectionSettings > Enabled="True".
• text box mode is set to ReadOnly: WebCombo > LayoutSettings > TextBoxMode="ReadOnly"

This settings populates the WebCombo in order to use checkbox mode multiple selection. There is no "search the values" in checkbox-mode multiple selection. You might want to try the other option of multiple selection such as shown in this sample. This "outlook-style" multiple selection sample allows user to search values by typing. You only need to enable MultipleSelectionSetting from WebCombo's Properties.

Hope this helps.
