I have a telerik:RadGrid that is configured to automatically adjust the column width based on its data. It does so, but an oddity still persists. When I scroll horizontally to the right, the end columns adjust to fill the entire width of the RadGrid, even though its contents were displayed fully already. Scrolling to the right inflates a 300px-wide column width to three or four times its width.

I'm not sure where to go from there. Aside from that issue, everything else is behaving as I intended.

My code:

<telerik:RadCodeBlock runat="server">
  <script type="text/javascript">
    function reqStart_aegv(sender, args) {
      if (args.get_eventTarget().indexOf("gridToolBar") > 0 && args.get_eventArgument() === "1")
    function disableAjaxIfExport_aegv(sender, args) {
      if (args.get_item().get_commandName() === "Export")
    function pageLoad() {
      var grid = $find("<%= EntityRecordListGrid.ClientID %>");
      var columns = grid.get_masterTableView().get_columns();
      for (var i = 0; i < columns.length; i++) {
        columns[i].resizeToFit(false, false);
        if (columns[i]._element.UniqueName != "btnEdit" && columns[i]._element.UniqueName != "btnDelete") {
          if (columns[i]._element.clientWidth < 125) {
            grid.get_masterTableView().resizeColumn(i, 125);
          } else if (columns[i]._element.clientWidth > 300) {
            grid.get_masterTableView().resizeColumn(i, 300);
<telerik:RadAjaxPanel ID="radAjaxPanel" runat="server" LoadingPanelID="radAjaxLoadingPanel" ClientEvents-OnRequestStart="reqStart_aegv">
  <asp:Panel runat="server" ID="panelGrid">
    <telerik:RadGrid runat="server" ID="EntityRecordListGrid" GroupingSettings-CaseSensitive="False" AllowPaging="True" AllowSorting="True"

Could you please elaborate on what version of the controls is the project using? If it relies on an older version please upgrade to the latest.

If this is not the case however and the application/web site already uses the latest version please send us a small runnable sample in which the problem can be replicated, as I do not see anything disturbing in the code.
