I have the following code as part of FormTemplate.

It works fine in IE but in Chrome it throws an exception as soon as you click the cancel button:

System.Web.HttpException: Maximum request length exceeded.

I've tried everything and none of those worked for me. 

Note: if I remove the RadEditor's from there the Cancel button works fine in Chrome too.

Thanks

P.S. I am using a trial (current version)

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?

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);
                }
            
        }

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.
