I have tried the following codes but nothing hides the radtab on indexchange

RadTabStrip1.Tabs[1].Visible = false;
                        RadTabStrip1.Tabs[1].Width = 0;
                        RadTabStrip1.Tabs[1].Height = 0;
                        RadTabStrip1.Tabs[1].Attributes.Add("style", "display: none;");

Hi, I Have a problem with grid. I'm exporting to excel data from my grid and next in excel I see strange buttons/rectangles.

I don't know how to remove these settings in export to excel.

Can u help me with this? How to remove this buttons..

I think this problem is because in headers I have filters... But when I set rgProjectList.MasterTableView.AllowFilteringByColumn = false still I have this "buttons"

Here is how I m doing export (rgProjectList is my grid.):

private void HandleExporting()
        {
            hlExportToExcel.NavigateUrl = this.Page.Request.Url.AbsolutePath + String.Format("?{3}={0}&{1}={2}&CurrentPage={5}&PageSize={6}{4}&Export", this.FilteringManager.ViewId.ToString(), ProjectListWeb.ActionQueryParameterName, ProjectListWeb.ExportExcelActionName, ProjectExtendedPropertiesFilteringManager.QueryStringViewParameterName, IsReportView ? "&ReportView=1" : "", GridCurrentPage, GridPageSize);
            hlExportToExcel.Target = "_blank";
            hlExportToCsv.NavigateUrl = this.Page.Request.Url.AbsolutePath + String.Format("?{3}={0}&{1}={2}&CurrentPage={5}&PageSize={6}{4}&Export", this.FilteringManager.ViewId.ToString(), ProjectListWeb.ActionQueryParameterName, ProjectListWeb.ExportCsvActionName, ProjectExtendedPropertiesFilteringManager.QueryStringViewParameterName, IsReportView ? "&ReportView=1" : "", GridCurrentPage, GridPageSize);
            hlExportToCsv.Target = "_blank";
            rgProjectList.ExportSettings.ExportOnlyData = false;
            rgProjectList.ExportSettings.FileName = "ProjectsList";
            rgProjectList.ExportSettings.IgnorePaging = true;
            rgProjectList.ExportSettings.Csv.EncloseDataWithQuotes = true;

            if (this.isExporting)
            {
                rgProjectList.ExportCellFormatting += rgProjectList_ExportCellFormatting;
                rgProjectList.MasterTableView.AllowFilteringByColumn = false;
                rgProjectList.CurrentPageIndex = rgProjectList.MasterTableView.CurrentPageIndex = GridCurrentPage;
                rgProjectList.PageSize = rgProjectList.MasterTableView.PageSize = GridPageSize;

                if (rgProjectList.MasterTableView.Columns.Count > 3)
                {
                    HideColumnsBeforeExport();
                    GridBoundColumn boundColumn;
                    boundColumn = new GridBoundColumn();
                    boundColumn.DataField = "Status";
                    boundColumn.HeaderText = "Status";
                    boundColumn.UniqueName = "Status";
                    GridBoundColumn boundColumnWT;
                    boundColumnWT = new GridBoundColumn();
                    boundColumnWT.DataField = "VPProjectEndTimeIndexExport";
                    boundColumnWT.HeaderText = "Wskaźnik terminu";
                    boundColumnWT.UniqueName = "VPProjectEndTimeIndexExport";
                    
                    rgProjectList.MasterTableView.Columns.Insert(0, boundColumn);
                    rgProjectList.MasterTableView.Columns.Add(boundColumnWT);

                }
                rgProjectList.MasterTableView.AllowSorting = false;
                rgProjectList.MasterTableView.CommandItemDisplay = GridCommandItemDisplay.None;
                rgProjectList.MasterTableView.AllowPaging = false;
                rgProjectList.MasterTableView.AllowCustomPaging = false;                
                rgProjectList.MasterTableView.ExportToExcel();
            }
            if (this.isExportingCsv)
            {
                this.CsvExportManager = new FlexiCsvExportManager();
                this.CsvExportManager.SetExportSettings(rgProjectList, GridCurrentPage, GridPageSize);
            }
        }

I have a masterpage where a have defined a function below

 function PopUpShowing(sender, eventArgs) {
                var popUp = eventArgs.get_popUp();
                var scrollTop = (typeof window.innerHeight != 'undefined' ? 0 : document.documentElement.scrollTop);
                var popUpWidth = popUp.style.width.substr(0, popUp.style.width.indexOf("px"));
                var popUpHeight = popUp.style.height.substr(0, popUp.style.height.indexOf("px"));
                var windowHeight = (typeof window.innerHeight != 'undefined' ? window.innerHeight : document.body.offsetHeight - scrollTop);
                var windowWidth = document.body.offsetWidth;
                if (popUpHeight == "") popUpHeight = 300; // if the height isn't set on the popup, default to 300px 
                popUp.style.position = "fixed";
                popUp.style.left = (Math.floor((windowWidth - popUpWidth) / 2)).toString() + "px";
                popUp.style.top = (Math.floor((windowHeight - popUpHeight) / 4) + scrollTop).toString() + "px";
            }

Then i have i page that opens a radwindow on button click. The radwindow contains a radgrid that has a popup editing set. So i want to call the PopUpShowing function in the masterpage to display the popup.

Hi,

we are running with 2012.1.411.35 version telerik.web.ui dll in our server with two applications. Now, we are planning to upgrade only one application to  telerik version 2017.2.711.35.

Is it possible running two application with two version of telerik dlls on the same server?

Hi,

I have a pivot grid as per picture below. For Total Ratio row, need to display a value with custom calculation. Following is my calculation format.

A = SumOfQty Won
B = SumOfQty Pending
C = SumOfQty Quoted
D = SumOfQty Lost

Format Ratio (%) = [A / (A+B+C+D)] * 100 

How to do it using code behind C#? I put my sample aspx code here.

Thank you.
