Could I ask if I'm able to create empty group with RadGrid grouping feature?

I've seen 'group by month' example in code library and I wish all 12 months were there, not only those existing in the data source.

I could use master-detail feature which would display empty detail table, but I would like to have common header consisting of only detail columns' names and some group information (like name of the group), that's why I think grouping feature suits better. Please let me know if I'm wrong and it's possible to create master-detail report, so that it looked as it was grouped.

Thanks in advance,
Alexander

I have a problem when try to add telerik components to my web application.

I used telerik version 2016.1.113.45. 

I need your help how to solve this issue below:

My problem is, nothing happens, the code behind doesn't fire...Maybe someone could point me in the right direction. Is it possible to do something like this or am I totaly wrong here?
default.aspx:

<telerik:RadAsyncUpload ID="RadAsyncUpload1"
         runat="server"
         CssClass="async-attachment"
         MultipleFileSelection="Automatic"
         RenderMode="Lightweight"
         OnFileUploaded="UploadFiles"
         TargetFolder="../App_Themes/media"
         HideFileInput="true"
         Localization-Select="اختر الملف"
         AllowedFileExtensions=".mp4,.webm,.ogv"
>

 

Default.aspx.cs

public void UploadFiles(object sneder, FileUploadedEventArgs  e)
    {
 const string relativePath = "~/App_Themes/media";
        var filename = e.File.FileName;
        var parentID = Convert.ToInt32(GridView1.SelectedValue);
        var filesize = Convert.ToInt32(e.File.ContentLength);
        var physicalSavePath = MapPath(relativePath) + filename;
 
        //Store file info in database
            var app_FilesAdapter = new app_FilesTableAdapter();
            app_FilesAdapter.Insert(filename, relativePath + filename, parentID, 1, DateTime.Now, filesize);
 
        //Save physical file on disk
            e.File.SaveAs(physicalSavePath, true);
}

Hi

I wana to fetch page size  of radgrid record from data base , but in your online demo code  , you used   (select * from xxx) !...

in this link

http://demos.telerik.com/aspnet-ajax/grid/examples/performance/linq/defaultcs.aspx

you talk about performance ! but if my table has a lot of recored , why i should fetch all of them ???

In  asp.net 4.5  for   "  asp:GridView  " control i can use this code :

 

public IEnumerable<SearchProvince> GetProvinces(int startRowIndex, int maximumRows, out int totalRowCount,
             [System.Web.ModelBinding.Control("pID")]int? provinceId,
             [System.Web.ModelBinding.Control("pName")] string provinceName)
        {
            using (var db = new XXXEntities())
            {
                IQueryable<Province> list =
                    (from p in db.Provinces
                     select new SearchProvince { ProvinceID = p.ProvinceID, ProvinceName = p.ProvinceName }).OrderBy(
                            p => p.ProvinceName);

                if (provinceId > 0)
                {
                    startRowIndex = 0;
                    list = list.Where(p => p.ProvinceID == provinceId);
                }
                if (!string.IsNullOrWhiteSpace(provinceName))
                {
                    startRowIndex = 0;
                    list = list.Where(p => p.ProvinceName.StartsWith(provinceName));
                }
                totalRowCount = list.Count();
                return list.Skip(startRowIndex).Take(maximumRows).ToList();
            }
        }

 

How can i implement this code for  RadGrid ?

 

thanks

Hello
I have a radgrid. When I add a record, in the edit mode, I would like to set a maxlength to my gridBoundColumn which is multiline. I saw that I can't do that, does it have a workaround for this?

Thanks!

There seems to be a bug in the latest release 2016.1.113. We have RadButtons using the ToggleType of Radio and the ButtonType of StandardButton like so:

<telerik:RadButton ID="rbCreditCardPresent" runat="server" ToggleType="Radio" ButtonType="StandardButton" GroupName="paymenttype" ValidationGroup="pospay" AutoPostBack="false" Text="CC - Present" OnClientClicked="CheckChanged" CommandName="Present" Width="125px">

Using version 2015.1.401 the width has always been properly displayed. After upgrading to 2016.1.113 it seems like the width if basically ignored. The buttons end up being the width of the text like in the attached image. 

 It seems like a workaround is to add a CSS class like the following, however that is kind of an annoyance and in Chrome this causes the text to dance around in the box when the page is loading. Is this truly a bug or am I missing something?

.wide input {
    width: 100% !important;
}

Hi, 

On a RadTreeList I would like to set ExpandCollapseMode="Client", so that all the expand/collapse is left to the client side, as this improves UX for my application. However, I have noticed that by setting this attribute on the RadTreeList definition, every time my RadTreeList loads (on page load) it is fully collapsed. (See attached image). Even if the last call I make server side is rtlTreeList.ExapandAllItems(); 

 I assume that on the client side, the nodes are being collapsed by default - is there any way to alter this behaviour? When my RadTreeList loads, it is also disabled, to allow read only access, which is why I would like the tree to load fully expanded.  Or perhaps there is a better way to make a RadTreeList disabled, but viewable other then setting each node to disabled? 

 

Thanks,

Craig

Is it possible to add a customized map in RadMap by your own instead of using default maps?

For example, I would like to use a customized image as a map in RadMap and use its properties for location points. See image below as example.
