I have file with file name
special character- ! @ # $ % ^ & () _ + =- {} _ ' -`.xlsx and unable to download.

Please find below the code snippet i used.

In rowdatabound client side..

C#

function rgAttachment_RowDataBound(sender, eventArgs) {
    var res = "";
    if (eventArgs != null) {
        var gridItem = eventArgs.get_item();
        var rowElement = eventArgs.get_item().get_element();
        if (gridItem != null) {
            try {
                var rowIndex;
                try { rowIndex = eventArgs.get_item()._element.rowIndex.toString() }
                catch (sError) { rowIndex = eventArgs._element.rowIndex.toString() }
                var FilePath1 = eventArgs.get_dataItem()["FilePath"];
                var FilePath=encodeURI(FilePath1);

Here i got the FilePath then it will set into onclick method inside rgAttachment_RowDataBound please see below

C#

var imgViewAttachment = sender.get_masterTableView().getCellByColumnUniqueName(eventArgs.get_item(), "imgViewAttachment");
                imgViewAttachment.setAttribute('onclick', 'ViewAttachment(\'' +FilePath+ '\');');
                imgViewAttachment.title = "View Attachment";

However onclick is not firing with the filename mentioned above.

C#

function ViewAttachment(filePath) {
    
    var w = 600, h = 540;
    if (document.all) {
        /* the following is only available after onLoad */
        w = document.body.clientWidth;
        h = document.body.clientHeight;
    }
    else if (document.layers) {
        w = window.innerWidth;
        h = window.innerHeight;
    }

    var popW = 100, popH = 100;
    var leftPos = (w - popW) / 2, topPos = ((h - popH) + 100) / 2;
    window.open('../Pages/FileReader.aspx?fileName=' + filePath +'&PageFrom=REPORTS', '', "scrollbars=yes,resizable=yes,width=" + popW + ",height=" + popH + ",top=" + topPos + ",left=" + leftPos);
    return false;
}

Sounds like you need to rename your files before trying to download them.

What is the exact error you get?

The error comes from that you are passing your filename through a GET reqest. To make this work you need to URL encode your filename first:

function ViewAttachment(filePath) {
    
    var w = 600, h = 540;
    if (document.all) {
        /* the following is only available after onLoad */
        w = document.body.clientWidth;
        h = document.body.clientHeight;
    }
    else if (document.layers) {
        w = window.innerWidth;
        h = window.innerHeight;
    }
 
    var popW = 100, popH = 100;
    var leftPos = (w - popW) / 2, topPos = ((h - popH) + 100) / 2;
    window.open('../Pages/FileReader.aspx?fileName=' + encodeURI(filePath) +'&PageFrom=REPORTS', '', "scrollbars=yes,resizable=yes,width=" + popW + ",height=" + popH + ",top=" + topPos + ",left=" + leftPos);
    return false;
}
