So i am using a RadGrid in a custom control. In the java script i am binding the grids events to events declared in my custom control. The issue is the rowCreated function is not firing until i actually click a row. Since its within a prototype i have to create it as a delegate to ensure i can still access other variables in the same scope.

But this causes the rowCreated event to not fire until i interact with the grid by selecting a row. Could someone give me some guidance on this please, it may be something obvious as i am fairly new to webforms controls. I have added the full code below, but have cut it down to be relevant.

Hi, I have the following button in the radgrid

  <telerik:GridButtonColumn CommandName="CustomDelCommand" ConfirmText="Delete this record?" ConfirmDialogType="RadWindow" ItemStyle-Width="18" HeaderStyle-Width="18"
                        ConfirmTitle="Delete" ButtonType="FontIconButton" >
                    </telerik:GridButtonColumn>

My item command code is here, the problem is the event not firing for chrome, safari. IE no problem. Anyone any idea?

 protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
        {
            if (e.CommandName == "CustomDelCommand")
            {
                MailAddress addr = new MailAddress(User.Identity.Name);
                string username = addr.User;
          var Id = (int)((GridDataItem)e.Item).GetDataKeyValue("id");

//del id record.
               
            }
        }

One of our Grids is basically a build your own query page and can often return upwards of 50 pages of 50 items.

We want the select all checkbox to select all the items across all the returned pages. However, the default functionality is to only select what's on the current page.

The official workaround is to temporarily set the page size to that of the datasource.data().length, select all the items, then return the page size to what it was previously.

The problem is that grid.dataSource.pageSize() doesn't return a promise. It only returnsthe current page size... asynchronously and instantly. The example shown for the workaround, as far as I can tell, could never have worked.

Does anyone have a solution to selecting all items when you have several pages of data?

I've a Grid with one of the Columns "No. of Notes" which hold link int values.

When clicked on one of the value I want to open a window which shows already existing notes, who and when was the note entered and should allow the user to enter any new notes. The user shouldn't be able to edit existing notes.

Do you have any specific control to handle this? Or any suggestions on how to achieve this will be appreciated. 

Hi team,

I've got issue when binding a dynamic Datatable to kendoGrid, the data of boolean column is auto converted to false when it's null.

Is there anyway to handle this case, please advise.

Thanks

Hi there, 

I'm having a problem with my radrid multi-level grouping.

When a Ajax request occours my grid loses all data.

I show my source code.

And respective code-behind

Someone can help me?

Best regards,

I'm using the RadAsyncUpload to upload files to a custom handler which stores the files into our database.  The custom handler returns a key value for the file which I want to then use during form postback to attach those uploads to the current record (which may be a brand-new record).  I can see the custom returned data on the client in OnClientFileUploaded() by using args.get_fileInfo().  From that standpoint I have everything working, upload, saving, validation, returning the file key.

Here's my definition of RadAsyncUpload:

                           <telerik:RadAsyncUpload RenderMode="Lightweight"

                                ID="AttachmentAsyncUploader"
                                runat="server"
                                CssClass="async-attachment"
                                MultipleFileSelection="Automatic"
                                UploadedFilesRendering="BelowFileInput"
                                OnClientFileSelected="OnClientFileSelected"
                                OnClientFileUploading="OnClientFileUploading"
                                OnClientValidationFailed="OnClientValidationFailed"
                                OnClientFileUploaded="OnClientFileUploaded"
                                OnClientFileUploadRemoved="OnClientFileUploadRemoved"
                                MaxFileSize="26214400"
                                DropZones="#DropZone"
                                HttpHandlerUrl="~/FileUploader.ashx"
                                HideFileInput="true">
                                <Localization Select="Select Files for Upload" />
                            </telerik:RadAsyncUpload>

Now the user posts the form back, so I call AttachmentAsyncUploader.UploadedFiles() which gives me a list of the files that were uploaded, but I can see no way to access the custom fileInfo fields that were returned by the handler.  Obviously just the file name isn't enough to figure out which attachments need to be attached to the newly created records.

Here is how I'm building and returning the meta-data from the custom handler, FileUploader.ashx (most importantly AttachedFileGuid):

            var result = CreateDefaultUploadResult<FileUploaderResult>(file);

             result.AttachedFileGuid = InsertFile(file);

             return result;

What is the expected way to get the full information about the uploaded files back to the postback?  Obviously, I can build my own field to store all that, but it seems an awful hack to use RadAsyncUpload and then just ignore it completely on postback.

Thanks in advance,
