Using a radgrid with AllowFilteringByColumn="true" I get this error:
“Invalid Column Name …”.

The SQL request used for data binding is :
SELECT myName AS [Another name] FROM TEST

So, I think the problem is the alias, but I don’t know how to solve it.

Could anyone help me, please?

Hi,

I have two raddatepicker columns as follows:
<telerik:GridTemplateColumn DataField="ItinDate" HeaderText="FromDate"  UniqueName="Date">
                                                <EditItemTemplate>
                                                    <telerik:RadDatePicker ID="ItinDateRadDatePicker" runat="server" Skin="Outlook"
                                                        DatePopupButton-TabIndex="-1" DbSelectedDate='<%# Bind("ItinDate") %>'  >
                                                     <ClientEvents OnDateSelected="CheckFromDate"  />
                                                    </telerik:RadDatePicker>
                                                   <asp:RequiredFieldValidator ID="RequiredFieldValidator4" runat="server" ForeColor="Red"
                                                        ControlToValidate="ItinDateRadDatePicker" ErrorMessage="Invalid Date"
                                                        ValidationGroup="ItineraryGrid"></asp:RequiredFieldValidator>
                                                     
                                                </EditItemTemplate>
                                                
                                                <ItemTemplate>
                                                    <asp:Label ID="ItinDateLabel" runat="server"
                                                        Text='<%# Eval("ItinDate", "{0:MM/dd/yyyy}") %>'></asp:Label>
                                                    &nbsp;
                                                </ItemTemplate>
                                            </telerik:GridTemplateColumn>
                                             <telerik:GridTemplateColumn DataField="ItinToDate" HeaderText="ToDate"  UniqueName="ToDate">
                                                <EditItemTemplate>
                                                    <telerik:RadDatePicker ID="ItinToDateRadDatePicker" runat="server" Skin="Outlook"
                                                        DatePopupButton-TabIndex="-1" DbSelectedDate='<%# Bind("ItinToDate") %>' >
                                                         <ClientEvents OnDateSelected="CheckToDate"  />
                                                         
                                                    </telerik:RadDatePicker>

                                                        ValidationGroup="ItineraryGrid"></asp:RequiredFieldValidator>
                                                  
                                                </EditItemTemplate>
                                                <ItemTemplate>
                                                    <asp:Label ID="ItinDateToLabel" runat="server"
                                                        Text='<%# Eval("ItinToDate", "{0:MM/dd/yyyy}") %>'></asp:Label>
                                                    &nbsp;
                                                </ItemTemplate>
                                            </telerik:GridTemplateColumn>

I have CheckFromDate and CheckToDate javascript functions to validate these dates against the trip begin and end dates on my form.
My javascript code is as follows:

 function CheckFromDate(sender, args) {
        try {
            var itinStartDtInput = $("#ctl00_MainContent_ItineraryGrid_ctl00_ctl02_ctl03_ItinDateRadDatePicker_dateInput_text");
            var tripStartDt = $("#ctl00_MainContent_TripStartDate_dateInput_text").val();
            var parsedStartDate = Date.parse(tripStartDt);
            //StartDt = parsedStartDate.getMonth() + 1 + "/" + parsedStartDate.getDate() + "/" + parsedStartDate.getYear();
            //alert("Start Date " + StartDt);

            var tripEndDt = $("#ctl00_MainContent_TripEndDate_dateInput_text").val();
            var parsedEndDate = Date.parse(tripEndDt);

            var ItinFromDt = args.get_newValue();
            var parsedItinFromDate = Date.parse(ItinFromDt);
            // alert("ItinFromDate " + ItinFromDt);

            if (parsedItinFromDate < parsedStartDate || parsedItinFromDate > parsedEndDate) {
                alert("Itinerary from date has to be between trip begin and end dates");
                args.IsValid = false;
                //return false;
                //args.set_cancel(true);
                window.setTimeout(function () { itinStartDtInput.select(); }, 20);
 
            }
            
        }
        catch (ex) {
            alert(ex);

        }
       
    }

    //// Check for Itinerary to date to be between trip begin and end dates
    function CheckToDate(sender, args) {
        try {
            var itinEndDtInput = $("#ctl00_MainContent_ItineraryGrid_ctl00_ctl02_ctl03_ItinToDateRadDatePicker_dateInput_text");
            var tripStartDt = $("#ctl00_MainContent_TripStartDate_dateInput_text").val();
            var parsedStartDate = Date.parse(tripStartDt);
            //StartDt = parsedStartDate.getMonth() + 1 + "/" + parsedStartDate.getDate() + "/" + parsedStartDate.getYear();
            //alert("Start Date " + StartDt);

            var tripEndDt = $("#ctl00_MainContent_TripEndDate_dateInput_text").val();
            var parsedEndDate = Date.parse(tripEndDt);

            var ItinToDt = args.get_newValue();
            var parsedItinToDate = Date.parse(ItinToDt);
            // alert("ItinFromDate " + ItinFromDt);

            if (parsedItinToDate < parsedStartDate || parsedItinToDate > parsedEndDate) {
                alert("Itinerary to date has to be between trip begin and end dates");
                //args.IsValid = false;
                //return false;
                //args.set_cancel(true);
                window.setTimeout(function () { itinEndDtInput.select(); }, 20);
            }

        }
        catch (ex) {
            alert(ex);
        }
    }

My problem is when user input the ItinDate, it runs the CheckFromDate validation and then the hits ok on the popup alert message, and can tab through to the next field, even if the date entered is not between the trip begin and end dates. How do I ensure that the user enters a valid date (which is between the tripbegin and end dates) before they tab to the next field on the grid?

Thanks, Janaki

I have a question. Is it possible to use JSON to query a web service and return a RadListViewItem (or preferably an array of them) to then append to the current listview on the page without a postback or lengthy ajax call? I have watched a few of the demos on how to use JSON and a web service but it didn't entirely help (new to JSON). Anyways, I am essentially making a commenting system and I want people to be able to load comments on demand and post new comments without experiencing a somewhat lengthy AJAX call using the panels or postingback completely. Right now when someone ads a new comment it actives the radajax components of the panel to make the call. It isn't terrible but I want something a little faster and seemless for the user. Let me know if something like this would work and if so, where I might start (specifically how to handle the return):

User wants to view more comments:

On page load (load top 30 results)
click "more" button and use JSON to get an array of RadListViewItems and append them to the current list view at the bottom (everything is ordered by date).

User wants to post:
Use JSON to write post to database (I can do this)
get the new record and return it as a RadListViewItem.

Thanks for all of your help guys.

Is it possible to filter records onTextChanged or onKeyUp event of internal TextBox(Header TextBox) of Radgrid?
I dont want to select 'Start With', 'Contains' and other options from dropdown to filter records in Radgrid.

Find the attached file for more understanding...

I can only seem to reproduce this in Chrome.  When a document is long enough to require a scrollbar, scrolling will put horizontal lines over the newly viewable part of the document. It seems to be related to the <td> which has a border that the iframe is in.  If I change the color of the border-bottom the lines output over the document change with it. I thought removing the border would resolve the issue, but it puts white lines over instead of black, transparent border has the same effect.  I can't seem to reproduce this in Chrome with regular iframes or any of the official demonstrations on this website.  

I have tried changing ContentAreaMode to DIV and although the lines do not appear with this it causes other issues so isn't a viable solution.

Any help anyone has would be much appreciated.
