I have a problem with the treeview in ie8, there the border on top of a node is not shown. (See attached screenshots)

Does anyone has any idea how to solve this?

RadComboBox Bound to string[] Not Selecting Specified Value

I have a RadGrid with an EditForm containing a RadComboBox. The RadComboBox has a datasource set to a string[] (DataSource='<%# GetSampleValues() %>'). When creating and editing a record, the combobox displays the correct strings in the dropdown list. When Editing an existing record, the selected string before expanding the combobox is not displaying the appropriate value.

                    <rad:RadComboBox ID="rcb_SampleValues" runat="server" AllowCustomText="false"         
               DataSource='<%# GetSampleValues() %>'          
               Text='<%# Bind("SampleValueString") %>'         
               Value='<%# Bind("SampleValueString") %>'         
               MaxLength="255"          
               Width="100" >         
            </rad:RadComboBox>         

                    public enum SampleValues         
            {         
                 SampleValue1,         
                 SampleValue2         
            }
            
                                                                public class Samples                     
                        {                     
                             public int ID { get; set; }                     
                             public string Name { get; set; }                     
                             public SampleValues SampleValue { get; set; }                     
                             public string SampleValueString { get; set; }                     
                        }                    
                                

                    public void Page_Load(object sender, EventArgs e)
            {
            BindGridData();
            }
            
            public void BindDataGrid()
            {
            Samples[] samples = GetObjectsFromDataAccessLayer()
            radGrid.DataSource = samples;
            }
                    
            public static string[] GetSampleValues()         
            {         
                 return Enum.GetNames(typeof(SampleValues));         
            }         

I am binding the RadComboBox to an array of strings which are generated off of an Enum - but the same problem happens when I bind the RadCombobBox to a set of objects and set the DataTextMember and DataValueMember. I have a sample application that I can send to someone that would like to see it.

Any ideas on what is not being done to make the comboBox NOT set to the intended value when the record is loaded?

Drag and Drop enabled Grid inside another Master Grid

Hello experts,

I am new to telrik controls. I have been struggling with this past few days now.

I have a master grid that shows lets say DEPARTMENTinformation.

Then I want to have a child grid that will list all the COURSES under that dept.

I want the courses to be drag and droppable within the same grid so that we can change the priority or the order of showing.

I have implemented a grid inside a grid and enabled drag and drop on the inside grid. Then I have tried to incorporate the code behind functionality to drag and drop but I cant get the OnNeedDatasource to work right on the child grid. Once I can do that, I may be able to something like this according to the drag and drop example :

        protected void grdPendingOrders_NeedDataSource(object source, GridNeedDataSourceEventArgs e)
        {
            grdPendingOrders.DataSource = PendingOrders;
        }

I am not sure if I am going the right direction, so I am ready to try a different approach altogether... Please provide some directions...

Thanks.
Bobby.

RadUpload work not stable on IE when set validate file size !!!

Hi all,
Actual, I'm using RadAjax control Q3 2009, and I use RadUpload component for my DNN module (DNN version 5.0) to Upload file with validate file size before upload by set value for MaxFileSize property of RadUpload Component.

But I have problem, RadUpload work good with validate file size when upload on FireFox ( with localhost address and share web address), but It run not stable on IE8 (with localhost address, sometime it can validate, sometime it can't. With share web address it does not completely work.)

I had read a help article Uploading Large Files to config in Webconfig file, You can see below:

<httpRuntime useFullyQualifiedRedirectUrl="true" maxRequestLength="2097151" requestLengthDiskThreshold="2097151" executionTimeout="3600000" />

but it also don't change. I don't know the reason why, because my Browser or because I don't know to config for RadUpload.

I'm using .NET FW 2.0, IIS 5.1. Everybody can help?, plz give me any idea for my problem....
Thanks so much.
