Request is not available in this context Error.

Hello i am trying to email the radgrid but i am unable to send it.

Its giving me error when i am trying to change it into Html.

Here is my code.

    
            public void SendPMRSetupGrid(string FromEmail, string ToEmail, string Subject, RadGrid Gridview1) 
        
                    { 
        
                        MailMessage MessageToSend = new MailMessage(FromEmail, ToEmail); 
        
                        MessageToSend.IsBodyHtml = true; 
        
                        MessageToSend.Subject = Subject; 
        
                        MessageToSend.Body = GridViewToHtml(Gridview1); 
        
                        this.Send(MessageToSend); 
        
                    } 
        
                    private string GridViewToHtml(RadGrid gv) 
        
                    { 
        
                        Page p = new Page(); 
        
                        p.EnableEventValidation = false; 
        
                        RadScriptManager ScriptManag = new RadScriptManager(); 
        
                        HtmlForm hf = new HtmlForm(); 
        
                        p.Controls.Add(hf); 
        
                        hf.Controls.Add(ScriptManag); 
        
                        hf.Controls.Add(gv); 
        
                        StringBuilder SB = new StringBuilder(); 
        
                        StringWriter stringWrite = new StringWriter(SB); 
        
                        HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite); 
        
                        p.DesignerInitialize(); 
        
                        p.RenderControl(htmlWrite); 
        
                        p = null; 
        
                        return SB.ToString(); 
        
                    }

I am getting the Exception at p.DesignerInitialize() method saying Request is not available in this context.... When i am using the normal Gridview i have no problem at all for sending it... But when trying to radgrid its throwing this exception.

Hi,

I need your help, pleas.. I'm trying to edit some fields in my detailsview and it works fine except the RadDateTimePicker.

I used it in the EditItemTemplate as below:

                    <asp:TemplateField HeaderText="IN">          
                            <EditItemTemplate>          
                                <telerik:RadDateTimePicker ID="RadDateTimePicker1" Runat="server"           
                                    AutoPostBackControl='<%# bind("CHECKIN") %>' Culture="English (United States)"           
                                    Enabled='<%# bind("CHECKIN") %>' SharedCalendar='<%# bind("CHECKIN") %>'           
                                    SharedTimeView='<%# bind("CHECKIN") %>' Visible='<%# bind("CHECKIN") %>' >          
                                             
                                </telerik:RadDateTimePicker>          
                            </EditItemTemplate>          
                                     
                            <ItemTemplate>          
                                <asp:Label ID="Label1" runat="server" Text='<%# eval("CHECKIN") %>' DataFormatString="{0:MM/DD/YYYY HH:MI:SS AM}"          
                                HtmlEncode="false">          
                                </asp:Label>          
                            </ItemTemplate>          
                                      
                        </asp:TemplateField>          

and i get this error:

System.InvalidCastException: Conversion from type 'Date' to type 'Integer' isnot valid.

i tried to solve this by many ways but all of them didn't work

I think the problem is in the data binding method but i couldn't find the correct format?

I appreciate your reply, Thanks

Error on control

I have 3 image buttons and a label. when i click on 2 of the 3 image buttons, the label gets updated with the appropriate text. when i click on the other, i get an error. they are exactly the same (from what i can see). here is the code (snippits):

When you click on the 2nd or 3rd image (ibCourse16 or ibCourse20), it works fine. When you click on the first (ibCourse17) you get an error.

You can also go to www.americance.com. From the home page in the 'Electrician' area, choose 'North Carolina' and any of the license types. Click the red 'Next'. FIRST: click on the middle image (NEC Grounding and Bonding Part I). The text at the bottom of the page changes. Click the third image (NEC Grounding and Bonding Part 2) - same result..all is ok. Click the first image. The text does not change and you see the 'Error on Page' at the bottom of the browser.

If I take this out of AJAX for course 17, I don't get an error, so it has something to do with that. However, it works for image 16 and 20.
<telerik:AjaxUpdatedControl ControlID="CourseCatalogDesc" />

I'm stuck....
Thanks,
Susan

Custom multi select combo box

Hi,
I am trying to create a user control to achieve multi select combo box functionality using RadComboBox. When click on check box of a combo box item i get System.Data.DataRowView instead of actual text value. Here are my code and pl help.

MultiSelectCombo.ascx
===================

A total of

Setting SelectedValue not working

    
            ddlRoles.SelectedValue = "User"

Trying to set the value of a RadComboBox(ddlRoles). The value exists in the combo box, but it is not being selected. Is this a known issue at all?
