I have a radeditor inside a radgrid inside a raddataform. How do I set the image upload path for the radeditor programatically in code-behind (C#)?

I have a RADComboBox on my ASPX page as shown below:

I Bind the ComboBox with this C# code:

 The Box functions properly on the page I can select an employee.

When I attempt to get the SelectedValue of the comboBox with this code it returns a null value.

Any idea why this happening?

Hello,

I want to implement RadGrid in which i am using telerik:GridTemplateColumn to bind data to link button. I want to open another page on click of this link and pass the value of the link as query-string. can anyone help me with the example? 

Hi I am using radgrid and I want to apply export excel functionality on that but when I am trying to add header using Prerender event it is not working for 

rgEnrolmentExport.ExportSettings.Excel.Format = GridExcelExportFormat.Xlsx;

I need this format to remove prompt which we normally get on opening of Xls file 

So please see code 

On aspx -

 <telerik:RadGrid ID="rgEnrolmentExport" OnPreRender="rgEnrolmentExport_PreRender" runat="server" AllowPaging="false" AutoGenerateColumns="true" ExportSettings-Excel-Format="Html">
                    <ExportSettings IgnorePaging="True" OpenInNewWindow="True" ExportOnlyData="True">
                    </ExportSettings>
                </telerik:RadGrid>

on C# 

  rgEnrolmentExport.DataSource = dtExportData;
                                    rgEnrolmentExport.DataBind();

                                    DateTime obj1 = (DateTime)rdpExportDate.SelectedDate;
                                    rgEnrolmentExport.ExportSettings.FileName = "HO_Enrollment_Source_Report_" + obj1.ToString("MM.yyyy");
                                    rgEnrolmentExport.ExportSettings.Excel.Format = GridExcelExportFormat.Xlsx;
                                  //  rgEnrolmentExport.ExportSettings.Excel.FileExtension = "Xlsx";
                                    rgEnrolmentExport.HeaderStyle.Font.Bold = true;
                                    rgEnrolmentExport.MasterTableView.ExportToExcel();

And in Prerender 

 protected void rgEnrolmentExport_PreRender(object sender, EventArgs e)
        {
            //get the current header 
           
                GridItem[] header = rgEnrolmentExport.MasterTableView.GetItems(GridItemType.Header);
                if (header.Length > 0)
                {
                    //get the current THead element 
                    DateTime obj1 = (DateTime)rdpExportDate.SelectedDate;
                    GridTHead head = ((GridTHead)header[0].Parent.Controls[0].Parent);
                    //Get the GridHeaderItem from the THead 
                    GridHeaderItem currentHeaderItem = (GridHeaderItem)head.Controls[0];
                    //Clear all GridHeaderItems 
                    head.Controls.Clear();
                    //create a new GridHeaderItem which will be the new row 
                    GridHeaderItem newHeaderItem = new GridHeaderItem(rgEnrolmentExport.MasterTableView, 0, 0);

                    // newHeaderItem.Cells.Add(new GridTableHeaderCell());


                    newHeaderItem.Cells.Add(new GridTableHeaderCell());
                    newHeaderItem.Cells.Add(new GridTableHeaderCell());
                    newHeaderItem.Cells.Add(new GridTableHeaderCell { Text = "Massachusetts", ColumnSpan = 3, HorizontalAlign = HorizontalAlign.Center });


                    newHeaderItem.Cells.Add(new GridTableHeaderCell { Text = "Rhode Island", ColumnSpan = 3, HorizontalAlign = HorizontalAlign.Center });

                    //  newHeaderItem.Cells.Add(new GridTableHeaderCell());
                    newHeaderItem.Cells.Add(new GridTableHeaderCell { Text = "New Hampshire", ColumnSpan = 3, HorizontalAlign = HorizontalAlign.Center });

                    // newHeaderItem.Cells.Add(new GridTableHeaderCell());
                    newHeaderItem.Cells.Add(new GridTableHeaderCell { Text = "All  EMembers", ColumnSpan = 3, HorizontalAlign = HorizontalAlign.Center });

                    // head.Controls.AddAt(0, newHeaderItem);
                    GridHeaderItem newHeaderItem1 = new GridHeaderItem(rgEnrolmentExport.MasterTableView, 0, 0);
                    newHeaderItem1.Cells.Add(new GridTableHeaderCell());
                    newHeaderItem1.Cells.Add(new GridTableHeaderCell());
                    newHeaderItem1.Cells.Add(new GridTableHeaderCell { Text = "Heating Oil Enrollment Sources Report for " + obj1.ToString("MMMMM yyyy"), ColumnSpan = 12, HorizontalAlign = HorizontalAlign.Center });


                    //Add back the GridHeaderItems in the order you want them to appear 

                    head.Controls.Add(newHeaderItem1);
                    head.Controls.Add(newHeaderItem);
                    head.Controls.Add(currentHeaderItem);
                }
            
        }

So basically if I am not applying Xlsx format it woking fine pelase see attachment it is exoporting what ever I need to do but with Xlsx format it throwing error.

So conclusion is I need to export file as I have attached in Image but in Xlsx format 

Hello,

I have implemented RadGid with filter options. I have 2 quries:

1. How to show default text e.g "Search..." for filters for some of the columns(not All columns). 

2. When user clicks on Filter Textbox it should populate all the values for that column.

Hello,

I am new to this forum and using Telerik controls for the first time.

I am using RadGid in Provider Hosted Add-In and so far could bind the data to it. My questions are:

I have written below code for that:
