Page don't stop loading after file download

Hello!

After downloading a file from a grid, my page keeps loading in loop, never stoppin. In order to be abble to do the download,

Along the way, i found out that the following function to disable AJAX was necessary to allow postback, so i believe the issue comes from here.

 function onRequestStart(sender, args) {
                           try {
                               if (args.get_eventTarget().indexOf("lnkDownload") >= 0) {
                                   args.set_enableAjax(false);
                                   return true;
                               }
                           }
                           catch (ex) {
                               alert("Error pushing postback: " + ex.message);
                           }
                       }

I also tried a similar function,, seting timeout in order to try to reestablish the normal behavour of the page, with any success.

function gridCommand(sender, args) {
                           if (args.get_commandName() == "download_file") { // "DownloadAttachment"
                               manager.set_enableAJAX(false);

                               setTimeout(function () {
                                   manager.set_enableAJAX(true);
                               }, 0);
                           }
                       }

Any ideas on the solution for this problem?

RadGrid: How can I apply ColumnSettings to my grid columns?

Hello,

I want to apply widths to certain columns, that are defined by a user. Since the columns themselves don't provide a Width-property, I tried to use the column settings of the MasterTableView.

I create the ColumnSettings like this:

string[] columnWidths = {"125", "164", "64", "125"};

foreach (string columnWidth in columnWidths)
{
    Grid.MasterTableView.ColumnSettings.Add(new GridTableView.PersistableColumnSetting
    {
           Width = columnWidth
    });
}

But I can't find any method to apply these settings to a grid column.
Do I miss something or is there an easier way to set the width of a column?

Negative Currency format in Export to excel format issue.

I am trying to get .xlsx export to not give this warning shown below.

I am using a RadGrid that AutoGenerates columns. The RadGrid's culture is en-US. Need Data source gets a DataTable with one column and one row, with the value of -4.50. On ColumnCreated it makes the GridNumericColumn Currency type. The Grid displays the format properly. It also puts the value into excel as though it looks correct.

**The problem I currently see is that it is putting a line break after the value in excel. Not sure why this is happening with the export?

Example of code:

(.aspx file)

<div class="form-row mt-4">
            <div class="col-md">
                <div class="form-inline float-md-right">
                    <telerik:radajaxpanel runat="server" postbackcontrols="btnExportTest">
                        <asp:Button ID="btnExportTest" OnClick="btnExportTest_Click" runat="server" Text="Export" />
                    </telerik:radajaxpanel>
                </div>
            </div>
        </div>
        <div class="form-row mt-4">
            <div class="col-md">
                <telerik:RadGrid ID="Grid1" RenderMode="Lightweight" Skin="Bootstrap" runat="server" OnNeedDataSource="Grid1_NeedDataSource"
                    AllowFilteringByColumn="false" AllowPaging="false" AutoGenerateColumns="true" OnColumnCreated="Grid1_ColumnCreated">
                </telerik:RadGrid>
            </div>
        </div>

(.cs)

protected void Grid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
        {
            DataTable table = new DataTable();
            table.Columns.Add("currency", typeof(double));
            table.Rows.Add("-4.50");
            Grid1.DataSource = table;
        }

        protected void btnExportTest_Click(object sender, EventArgs e)
        {
            Grid1.ExportSettings.IgnorePaging = true;
            Grid1.ExportSettings.FileName = "test";
            Grid1.ExportSettings.ExportOnlyData = true;
            Grid1.ExportSettings.OpenInNewWindow = true;
            Grid1.ExportSettings.Excel.Format = GridExcelExportFormat.Xlsx;
            Grid1.MasterTableView.ExportToExcel();
        }

        protected void Grid1_ColumnCreated(object sender, GridColumnCreatedEventArgs e)
        {
            if (e.Column is GridNumericColumn)
            {
                ((GridNumericColumn)e.Column).NumericType = NumericType.Currency;
            }
        }

I verified my windows settings are set up to show negative Currency with ($0.00).

This seems like it is just a problem with exporting from Telerik? Is there something that can make negative currencies export?

Currently using Q2 2021 Telerik version

<Telerik:RadGrid AllowAutomaticInserts="true" AllowAutomaticUpdates="true" On>
<Columns>

Closing RadWindow with Button in AjaxPanel (or RadAjaxManager)

I have a page with a popup RadWindow. In the RadWindow, users fill out a simple form and click on an OK button. The processing takes several seconds and sometimes users click on the OK button again. I am trying to find a way of disabling the OK button in javascript while the process runs, if the button is not in a RadAjaxPanel or one of the controls in a RadAjaxManager, the button does not change when it is disabled. When the button is n a RadAjaxPanel or one of the controls in a RadAjaxManager, I can't close the RadWindow.

I would think this is a pretty frequent issue. Anyone have any ideas? If you know of sample code that solves this I would really appreciate it!

Thanks
