I have a situation where a user uploads a file and we put that into a session variable and an imageeditor.
 protected void AsyncUpload1_FileUploaded(object sender, FileUploadedEventArgs e)
        {
            //Clear changes and remove uploaded image from Cache
          ImageEditor_CreateDonor.ResetChanges();
        //   Context.Cache.Remove(Session.SessionID + "UploadedFile");
            using (Stream stream = e.File.InputStream)
            {
                byte[] imgData = new byte[stream.Length];
                stream.Read(imgData, 0, imgData.Length);
                MemoryStream ms = new MemoryStream();
                ms.Write(imgData, 0, imgData.Length);

                Context.Cache.Insert(Session.SessionID + "UploadedFile", ms, null, DateTime.Now.AddMinutes(20), TimeSpan.Zero);
            }
        }

Then we put it into a image editor.
 protected void ImageEditor_CreateDonor_ImageLoading(object sender, ImageEditorLoadingEventArgs args)
        {
           
            //Handle Uploaded images
            if (!Object.Equals(Context.Cache.Get(Session.SessionID + "UploadedFile"), null))
           {
                using (EditableImage image = new EditableImage((MemoryStream)Context.Cache.Get(Session.SessionID + "UploadedFile")))
                {
                    args.Image = image.Clone();
                    args.Cancel = true;
                }
           }
        }
We the image is cropped we save the crop into the session variable.
 protected void RadImgEdt_ImageChanging(object sender, ImageEditorEventArgs e)
        {
           
            Context.Cache.Remove(Session.SessionID + "UploadedFile");
            Context.Cache.Insert(Session.SessionID + "UploadedFile", e.Image, null, DateTime.Now.AddMinutes(20), TimeSpan.Zero);
        }

Now once we save, we want to save in the db which is a byte[] format, it doesn't save correctly. (I will the comments in to show the various things I have tried.
protected void BtnDonorSave_Click(object sender, EventArgs e)
        {
            Boolean isLandingPage = false;
            string rtxtScholarshipName = this.txtScholarshipName.Text;
            string rtxtScholarshipDesc = this.txtScholarshipDesc.Text;
            byte[] fileData;


            MemoryStream file;
            EditableImage eImage;
            try
            {
                //UploadedFile file = AsyncUpload1.UploadedFiles[0];
                //fileData = new byte[file.InputStream.Length];
                //file.InputStream.Read(fileData, 0, fileData.Length);
              
                 file =
                     (MemoryStream) Context.Cache.Get(Session.SessionID + "UploadedFile");
                
                
               // UploadedFile file = AsyncUpload1.UploadedFiles[0];
               // var file = Context.Cache[(Session.SessionID + "UploadedFile")] as  MemoryStream;
                 fileData = new byte[file.Length];
                 file.Read(fileData, 0, fileData.Length);
            }

            catch (ArgumentOutOfRangeException e1)
            {
                Response.Write("<script>alert('Donor cannot be added without an image');</script>");
               
                return;
            }
       

            Int32 rcollegeId = Convert.ToInt32(this.collegeId.SelectedValue);
            string rtxtNotes = this.txtNotes.Text;
            if (chkBxNotes.Checked == true)
                isLandingPage = true;


            db.CreateDonor(rcollegeId, rtxtScholarshipName, rtxtScholarshipDesc, ReadFully(Context.Cache.Get(Session.SessionID + "UploadedFile") as MemoryStream), rtxtNotes, User.Identity.Name, DateTime.Now, isLandingPage.ToString()).Execute();
            //Response.Write("<script>alert('Donor Created');</script>");
            Session["CollDiv"] = collegeId.SelectedValue;
            Response.Redirect("DonorProfiles.aspx");
        }

So after save when I try to view the image it is a bad image.

Anyone know how to save a cropped image into a database from an imageeditor?

Thanks

I use telerik pie chart and I create it on server (from DB):

        private void cViolationsPerTime_NeedDataSource(object sender, EventArgs e)
        {
            Telerik.Reporting.Processing.Chart procChart = (Telerik.Reporting.Processing.Chart)sender;

            procChart.DataSource = BLL.BO.Audit.ExecuteAuditCommand(GenerateViolationsPerTimeSql(filters, "All"), type, conn, fromDate, toDate);

            Telerik.Reporting.Charting.ChartSeries csViolationsPerTime = new Telerik.Reporting.Charting.ChartSeries();
            csViolationsPerTime.DataYColumn = "NumOfViolations";
            csViolationsPerTime.Type = Telerik.Reporting.Charting.ChartSeriesType.Pie;
            csViolationsPerTime.DataLabelsColumn = "timeslot";

            csViolationsPerTime.Appearance.LegendDisplayMode = Telerik.Reporting.Charting.ChartSeriesLegendDisplayMode.ItemLabels;
            csViolationsPerTime.Appearance.ShowLabelConnectors = true;
            csViolationsPerTime.Appearance.TextAppearance.TextProperties.Font = new System.Drawing.Font("Calibri", 7F);

            cViolationsPerTime.Series.Clear();
            cViolationsPerTime.Series.Add(csViolationsPerTime);

        }


Attached screen shot with the result I get.
I want to get different legend then the data labels.
How can I bind a different column to the legend?

This is my SQL result:
timeslot     numOfViolations
10:00-12:00      40
12:00-14:00      10
14:00-16:00      8

etc...

I want each part of the pie to display the number of violations, and in legend I want to see the time slot.       

I have a rad splitter, inside that i have two RadPanes named as "rLeftPane" and "rContentPane".

In "rLeftPane" RadPane (ie. LEFT RadPane) I am loading an ASP.NET usercontrol which behaves as a menu, the usercontrol basically, is nothing but a RadWindow.

Now inside the "rContentPane" RadPane(ie. RIGHT RadPane) I am having another RadWindow named as "rwMain", which is used to load the aspx pages (combination of master page and content page), which is loaded in AJAX call and does not postback's the page.

Now what I want is, this, staying inside the "rContentPane" RadPane's (ie. RIGHT RadPane) RadWindow, at page loading, I want to access a control's present inside RadWindow which is in "rLeftPane" RadPane(ie. LEFT RadPane).

Here is the code :

<telerik:RadSplitter ID="Splitter" runat="server" Width="100%" Height="100%" VisibleDuringInit="false"
            Skin="Office2007" OnClientResizing="Resizing">

            <telerik:RadPane ID="rLeftPane" runat="server" Width="200" MinWidth="200" MaxWidth="200"
                OnClientCollapsed="WindowShow" OnClientExpanded="WindowShow" BackColor="DarkGray">

                <ERPx:LeftMainMenu ID="ucLeftMainMenu" runat="server" /> // This is my UserControl

            </telerik:RadPane>

            <telerik:RadSplitBar ID="VerticalSplitBar" runat="server" CollapseMode="Forward" EnableResize="false" />

            <telerik:RadPane ID="rContentPane" runat="server">

                <telerik:RadWindow ID="rwMain" runat="server" VisibleOnPageLoad="true" ShowContentDuringLoad="false"
                    OnClientShow="WindowShow" VisibleStatusbar="False" Behaviors="None" EnableShadow="false" OnClientBeforeClose="OnClientBeforeClose1" OnClientPageLoad="WindowLoad" IconUrl="images/18_users.gif" Skin="Office2007">
                </telerik:RadWindow>

            </telerik:RadPane>
        </telerik:RadSplitter>

Please help me out.

Thanks.

Hi All,

I'm using telerik 2013 Q3 for development. Now I want to implement a page that contains a radgrid, and the radgrid can expand to expand a DetailTables. The DetailTables has just one column GridTemplateColumn and in its ItemTemplate contains a RadTreeList.
My question is after click expand button, I cannot get RadTreeList instance whatever from dataBound, ItemCreated or anyother events. So how can I set datasource to the RadTreeList in DetailTables ItemTemplate.

Can anyone help on this, please? Thanks.

ello I've got some problem wih the paging of Telerik RadGrid Control! When it's first page - there is no problem it loads me three rows as I have givenpageSize property value - "3". But when I try to get to the second page - it gives me an error:



Here is my aspx file

<
And here is my cs File with only one function in which I get the data for datasource from a web service and bind it to the radGrid:

All,

I have table which is build in .net, dynamically (server side), which shows me an overview of all people that need to work on a specific day for a specific area.

A list is fine, but I would like to visualize this for users. I have multiple working area's and up to 20 people working per working area per day, so putting it all into an outlook style calender overview is useless as it will become to complicated.

I now had the idea to add a HR per entry (tr) which would correspond to the hours they need to work. (some like a range bar)

Attached the screenshot where i added the green lines in paint, to show what i'm trying to achieve. (The table is in Dutch but you can easily see what the working hours are)

Is there any telerik control that would offer this functionality?
