Hello,

 I'm new in telerik and I need some help.

 In my case everything works fine, except the validation of a field.

 On the line 327 there is a RequiredFieldValidator, the validation doesn't work at all. The validator and the RadTextbox that I want to be validated are inside a  RadWindow, as I can see the problem is somewhere related to RadWindow but I cannot find exactly what is the problem.

 I put my code below, please let me know if anyone has any solution about this issue.

 Thank You

Hello, 

I am trying to implement RadListView similar to this ListView - DataGrouping Demo. But I got very strange behaviour on page changes. I've set PageSize="5" in DataPager.

• Page 1: shows (5) items from 1 - 5 (Correct)
• Page 2: shows (10) items from 6 - 15 (Incorrect. Extra 5 items)
• Page 3: shows (15) items from 11 - 25 (Even worse. Extra 5 new items and 5 previous items. 11 to 15 was already shown on page 2)
• Page 4: shows (20) items from 16 - 35 (I've no idea)
• Page 5: shows (20) items from 21 - 40
• Page 6: shows (15) items from 26 - 40 (Reduced 5 items. All duplicated records from previous pages)
• Page 7: shows (10) items from 31 - 40 (Reduced 5 more items. All duplicated records from previous pages)
• Page 8: shows (5) items from 36 - 40 (Reduced 5 more items. All duplicated records from previous pages)
• Page 9: shows (5) items from next group
• Same Pattern ...

I am not sure my markup have problem or my data have. You can see​ my sample code that will create above result below. I also attached screen shots for faster reference.

Please help and thanks in advanced.

Hi all,

 I'm trying to validate some fields in a FormTemplate inside of a RadGrid and everything is working fine except for one problem. Whenever the submit button is pressed, an async postback is triggered and after postback the validators are triggered. Functionality wise it works fine, the update/insert isn't persisted, but I don't understand why the post-back is occurring (and causing the ajax loading panel to trigger) instead of the validation occurring all on the client side. Is it possible to prevent the post-back? Form is below and the page is using RadAjaxManager for async. Thanks.

Hi support Team,

 In Kendo ui Grid ...I am Apply the Composite Filter ...But Problem with The ...Here in Filter ....I have some  "True" or "False"  Column ......Instead of Showing The "True"  ...."Y" and "False" ...."N"...So  I am Apply Following Logic For that 

 C# Code When User Gives  "Y" or "N"....based on That  .....setting True or False.

   private static void addFilter(XElement newFilter, FilterDescriptor firstFilter, string crmAttributeName, GetCrmColumnName getColumnInfo)
     {
            if (firstFilter.Member == "OnHold")
         {
                if (firstFilter.Value.ToString().ToLower() == "y")
                {
                    firstFilter.Value = true;
                }
                else if (firstFilter.Value.ToString().ToLower() == "n")
                {
                    firstFilter.Value = false;
                }
            }
                newFilter.Add(new XElement("condition",
                    new XAttribute("attribute", crmAttributeName),
                    new XAttribute("operator", getOperator(firstFilter.Operator, crmAttributeName)),
                    new XAttribute("value", String.Format(getOperatorFormat(firstFilter.Operator), firstFilter.Value.ToString().Trim()))));           
        }

 After Result Came I Need To ..Assign Same "Y" or "N"

So I Write The Following code

    foreach (var n in request.Filters)
            {           
                    if (((FilterDescriptor)(n)).Member == "OnHold")
                    {
                        if (((FilterDescriptor)(n)).Value.ToString().ToLower() == "true")
                        {
                            ((FilterDescriptor)(n)).Value = "y";
                        }
                        else
                        {
                            ((FilterDescriptor)(n)).Value = "n";
                        }
                    
                }          
            }

It Work Fine ....For Normal Filter ...When ...I suppose ....Use CompositeFilter Then  I got Problem....If ...Work with Composite Filter ..I need Display ...Not Empty or an error...

  foreach (var n in request.Filters)
            {
                if (n is CompositeFilterDescriptor==true)
                {
                    if (((CompositeFilterDescriptor)(n)).FilterDescriptors.Count() >= 2)
                    {
                     
                    }
                }
                else
                {       
                    if (((FilterDescriptor)(n)).Member == "OnHold")
                    {
                        if (((FilterDescriptor)(n)).Value.ToString().ToLower() == "true")
                        {
                            ((FilterDescriptor)(n)).Value = "y";
                        }
                        else
                        {
                            ((FilterDescriptor)(n)).Value = "n";
                        }
                    }
                }          
            }

Currently.....It  Work For Composite Filter also..But when .....we Include Filter Of "Y" or "N".....I got ...Problem....When User Give even Though ..."Y" or "N"...Columns in the Composite Filter.....We need to Display....matched Columns.....

Hi Team,

We are using Telerik Rad editor in our SharePoint 2013 environment and activated "Use RadEditor to edit HTML fields" feature to replace the default Rich Html editor with Rad Editor. When we edit a page and make any changes in Rad editor content and check in the page, sometimes Rad editor looses its content and blank page gets checked in.

Kindly suggest how can we resolve this issue.

Thanks & Regards,

Hi There,

When looking for your client side documentation for RadComboBox today I notice that much of the API I am used to is not present. eg. set_text() and other accessors.

It appears there is only trackChanges and commitChanges listed as methods on the RadComboBox.

See http://docs.telerik.com/devtools/aspnet-ajax/controls/combobox/client-side-programming/objects/radcombobox-object

Just wondering where I can get access to this documentation online now.

Regards,

Daniel

Hi,

I am just wondering if there is full working example of a RadGrid with file download functionality anywhere?

My requirements are pretty simple - 

1. One of the grid columns will contain the actual name of the file (including extension) which I want to present as a clickable link (using asp:LinkButton maybe?).

2. Once the link is clicked the actual path to the physical file will have to be assembled in the code behind (don't want to expose file system details to the client apart from the file name).

3. The browser will allow the user to download the file in the normal way.

That's it. Just wondering if there is a good working example of this anywhere? Please let me know if any clarification is required. 

Thanks :)
