Column re-order problem after databind

I am having a problem with the RadGridView not allowing the user to re-order the columns via column header dragging after the grid has been bound to a data source. I can click and begin to drag a column header, however once I release the mouse button, the column returns to its original position, not the position I dropped it at. This only happens after I have bound the grid to a datasource.

Am I doing something wrong or is this expected behavior?

Using GridView version 2009.2.9.729

The code below is a form with a RadGridView and 3 columns. After I click the bind button, I can no longer re-order columns:

    
            using System;  
        
            using System.Drawing;  
        
            using System.Windows.Forms;  
        
            using System.ComponentModel;  
        
            using Telerik.WinControls.UI;  
        
            namespace TelerikGridTest  
        
            {  
        
                public partial class SimpleGridTest : Form  
        
                {  
        
                    private Telerik.WinControls.UI.RadGridView radGridView1;  
        
                    private void btnBind_Click(object sender, EventArgs e)  
        
                    {  
        
                        BindingList<SomeObject> data = new BindingList<SomeObject>();  
        
                        data.Add(new SomeObject("1.1", "1.2", "1.3", "1.4"));  
        
                        data.Add(new SomeObject("2.1", "2.2", "2.3", "2.4"));  
        
                        data.Add(new SomeObject("3.1", "3.2", "3.3", "3.4"));  
        
                        radGridView1.DataSource = data;  
        
                        //now I can't re-order columns

RibbonBar 3D Border on DropDownButton

Is there any way to remove the 3D effect on RadDropDownButtonElement controls that are added to a RadRibbonBar? I hate the way it looks in 3D. It seems to be based on the theme as changing my theme fixes the problem; however I want the color scheme of the Office2007 theme and that is where I have this terrible 3D effect on the borders.

Using masked edit box for variable length numeric data

I've tried using a masked edit box for data that should be numbers only. I set the mask type to standard and the mask to "##########", which is supposed to allow optional numbers up to 10 characters. What happens is that I can't tab out of the field unless I've entered 10 numbers, which is not what I want. I want up to 10 digits. I can't find documentation for the numeric masks, only for standard and date time. I don't know if using a numeric mask would do the job.

date bug with radscheduler q1

Hi,

I upgraded a project of mine that worked fine with all 2009 releases to radscheduler 2010 q1 and for some reason I noticed there when you click on a certain date the date that it shows in the edit appointment box is out by 1 day! So i created a new project and still get the same issue.

Steps to re-create:
-Create new project
-Add scheduler, navigator, datasource etc
-Group appointments by resource e.g.

"RadScheduler1.GroupType = Telerik.WinControls.UI.GroupType.Resource"

-run project, use scheuler navigator to change date
-click to add an appointment

Then note the date is out by 1 day...

Are there any work arounds or fixes planned for this?

Formated row doesnt anchor on scrolling

Hey Folks.

I'm currently stucked on a strange happening.

With the following code i'm formating a row, if cellvalue is changed.

    
            private void gv_data_CellValueChanged(object sender, GridViewCellEventArgs e) 
        
                    {             
        
                        GridViewRowInfo r = e.Row; 
        
                        ((GridCellElement)sender).RowElement.BackColor = Color.LightYellow; 
        
                        ((GridCellElement)sender).RowElement.DrawFill = true;   
        
                        r.Cells[1].Value = "1"; 
        
                    }

The BackColor appears to the row. Right so far.
But if im scrolling down then in the DataGridView, the formatting doesn't keep on its row, it's scrolling with.

Just want to highlight edited rows.

Any suggestions?

Kind regards, Tom

Can anyone please help.. I have create multiple child hierarchical grid but i cant seem to see the fourth level and fifth level. I dont know if its the size of the child template is the problem or something else. Isn't the child template autoresized?

Here is a copy of my code, if the problem is not what i stated please tell me what i'm missing thanks!

if (list.Keys.Count > 0)
            {
                //Child Template
                GridViewTemplate template = new GridViewTemplate();
                template.AllowAddNewRow = false;
                template.Columns.Add(new GridViewTextBoxColumn("ParentID"));
                template.Columns.Add(new GridViewTextBoxColumn("ID"));
                template.Columns.Add(new GridViewTextBoxColumn("Key"));
                template.Columns.Add(new GridViewTextBoxColumn("Value"));

                    string strCtr = parentID.ToString() + childCtr.ToString();

                    if (list.ValueIsList(str))

                    if (list.ValueIsString(str))
                    {
                        newTemplate.Rows.Add(parentID, strCtr, str, list.GetString(str));

How to prevent empty rows creation?

Hello.

When I enable rows creation in RadGridView and click that tells "Click here to add new row" new item is being added to binding source. But then if click somewhere (without entering any text to the cell) this empty row is being added to grid view. How can I change this behavior? I want that new row to be added only after entering some text or pressing "Enter" button.

Thanks.
