Hello there.

I am trying to get separate client validation messages for AsyncUpload depending upon whether it was a fail due to filesize or extention type.

At the moment i can only get a generic message using :

 function validationFailed(sender, eventArgs) {
              
            //var RadProgressArea1 = $('#<%= RadProgressArea1.ClientID %>');
//             $.each(sender, function(i, n) {
//                            alert("Name: " + i + ", Value: " + n);
//                        });    
            $("#errorHolder").append("<p>Validation failed for '" + eventArgs.get_fileName() + "'.</p>").fadeIn("slow");
        }

I want seperate messages for those two cases.

i have also tried to not specify maxfilesize in asyncupload and catch filesize error in 

function ClientProgressUpdating(sender, args)  {
           
           if(args.get_data().fileSize > 3145728)
           {                          
                sender.deleteFileInputAt(0);
                  $("#errorHolder").append("<p>file size if more than max for '" + eventArgs.get_fileName() + "'.</p>").fadeIn("slow");
//                if(confirm("Are you sure"))
//                {
//                   //validationFailed(sender, args);
//                   return false;
//                     $("#errorHolder").append("<p>Validation failed for '" + eventArgs.get_fileName() + "'.</p>").fadeIn("slow");
//                }
               
           }
//            
        }

it stops the fileupload but hangs at the screen where the progress bar is not moving forward and doesnt set the error message label

Thank you for helping.

Hello,

I've been struggling with this problem for many hours now.  Basically I'm interested in finding out how to have resizable detail table columns which don't mess up the grid size and scrolling when you resize them.

I've attached a small demo that shows the problem.  If you expand a detail record and then resize a column in it, the grid basically loses scrolling and resizes itself.  I have not enabled resize grid on column resize.

Help would be very much appreciated!  If there is a demo out there somewhere that shows resizable columns in a hierarchy that would be helpful as well.  I cannot find any demo on the Telerik site which shows hierarchy and resizable columns at the same time!

I'm using the RadAsyncUpload on a webform that have several components to perform certain operations. Initially, when I load the file, the FileUploaded is fired on the first postback as expected, and the file is copied to the intended directory in the server. This is my code for this part:

protected void AsyncUpload1_FileUploaded(object sender, Telerik.Web.UI.FileUploadedEventArgs e)
        {
            using (Stream stream = e.File.InputStream)
            {
                bool fileSaved = false;
                Random objRand = new Random();
                while (!fileSaved)
                {
                    string strUploadFileName = "~/tmp/" + DateTime.Now.ToString("yyyyMMddHHmmss") + ".xlsx";
 
                    if (!File.Exists(Server.MapPath(strUploadFileName)))
                    {
                        byte[] xlsData = new byte[stream.Length];
                        stream.Read(xlsData, 0, (int)stream.Length);
 
                        FileStream fs = new FileStream(Server.MapPath(strUploadFileName), FileMode.Create, FileAccess.ReadWrite);
                        BinaryWriter bw = new BinaryWriter(fs);
                        bw.Write(xlsData);
                        bw.Close();
 
                        ViewState["currXLFile"] = Server.MapPath(strUploadFileName);
                        //read contents now...
                        LoadData();
 
                        fileSaved = true;
                    }                
                 
                }               
                 
            }
        }

The problem is that there are other components that fire the postback event on the same page after the file upload, which fires over and over again the FileUploaded event, with the big problem that after the second time it postbacks it generates an exception at this line:

using (Stream stream = e.File.InputStream)

Which has sense since the file was copied already on the first postback, so the InputStream is not usable anymore. Can you recommend me a way to make sure that this line is excuted only when a file was actually uploaded and not on every single postback event? hopefully something more elegant of what I did for now: just putting a try-catch block and ignoring the error.

Thanks,

Hi all
I am developing an ASP.NET MVC application. I have radScheduler in one page connected to a web service which pulls appoinments from the database. There are different appoinment types and there is one appoinment which can be moved across time slots. I need to show that appoinment in the scheduler when the page is loaded(initially and dynamically with other client side events). In order to do that I need to set "TimelineView-StartTime" property. It is a serverside property and I cannot find the corresponding JavaScript property. Since this is an MVC application I cannot set the property within server side tags. Could you please tell me how to set this "TimelineView-StartTime" property in ASP.NET MVC application dynamically? I cannot find the corresponding JavaScript property.
Thanks in advance

Hi,
I am using a rad grid. I have added custom template columns dynamically. On template column i am having a custom multiselect combobox (RadComboBox with CheckBox and Label inside ItemTemplate).

How can i access the combo selected value on post back due to save buton click.
if possible send me sample solution with dynamically created multiselect ComboBox.

I am using following code snnipet for custom combobox:

public class CustomDDLItemTemplate : ITemplate
{

    ListItemType templateType;
    string ColName = "AppName";

    /// <summary>
    /// Create the template
    /// </summary>
    /// <param name="container"></param>
    public void InstantiateIn(Control container)
    {      
        CheckBox checkBox = new CheckBox();
        Label lblDisplayText = new Label();      

        checkBox.ID = "checkBox";
        checkBox.Attributes.Add("onclick", "onCheckBoxClick(this,'"+ container.ClientID +"');");
        
        lblDisplayText.ID = "label";
        lblDisplayText.DataBinding += new EventHandler(this.Label_DataBind);

        // Create a new HtmlGenericControl.
        HtmlGenericControl NewControl = new HtmlGenericControl("div");

        // Set the properties of the new HtmlGenericControl control.      
        NewControl.Attributes.Add("onclick", "StopPropagation(event);");

        // Add the new HtmlGenericControl to the Controls collection of the PlaceHolder control. 
        container.Controls.Add(NewControl);

        NewControl.Controls.Add(checkBox);
        NewControl.Controls.Add(lblDisplayText);              
        break; 
    }

    public void Label_DataBind(Object sender, EventArgs e)
    {
        Label lbl = (Label)sender;
        RadComboBoxItem radCombo = (RadComboBoxItem)lbl.NamingContainer;     
        lbl.Text = DataBinder.Eval(radCombo.DataItem, ColName).ToString();
    }

  
}

I'm using a RadToolTipManager and setting the body of my Tooltip in the .Text property (serverside).

I then add lots of tables cells to the TargetControls collection.

All works fine.

However, I want to call some javascript functions triggered by jQuery event listeners attached to elements with a known id within my Tooltip markup - e.g. a button.

This is only working for the Tooltip shown on the first table cell I hover over.

Looking at the source code, I see that a separate ToolTip is generated for EVERY cell I hover over.

This means the same id's appear multiple times - not only is this bad HTML but my triggers only work on the first one.

Is there a way to force the RadToolTipManager to only ever create one Tooltip and show that every time?

Thanks
