Bug: Setting background color of grid column not working well

Hello,

I set the background color of a grid column to red but it did not appear to work. When I scrolled down the cells began to appear read. When I scrolled back up to the top the cells that did not have a red background now had a red background.

Note. I have virtualizing turned on.

I switched off virtualizing and the command to change the background of the column red did not work at all. Here's the command:

gridname.Columns[<column to turn red>].Background = Brushes.Red;

Any help would be appreciated.

Thanks

Last row always selected and the first cell in edit mode

Hi,
i need that my last row in grid will be always selected and that the first cell in this row will be in edit mode.
BeginEdit() doesnt work for me becouse my ItemSource is not obserableCollection, its a custom collection:

    
             public interface ICustomObservableCollection<T> : ICollection<T>, INotifyCollectionChanged, INotifyPropertyChanged  
        
                    where T : EntityBase2, IEntity2  
        
                { }  
        
                public class CustomObservableCollection<T> : ICustomObservableCollection<T> 
        
                    where T : EntityBase2, IEntity2  
        
            {}

Thanx

RadGridView1.ChildrenOfType<GridViewRowItem>()

Hello

I want to search for a value in one of the columns in my grid and then select the row
I used this code to run on the items

    
            foreach (GridViewRowItem griParent in RadGridView1.ChildrenOfType<GridViewRowItem>())  
        
                                {  
        
                                    if (griParent.DataItem != null)  
        
                                    {  
        
                                        if ((griParent.DataItem as DataRowView).Row["ActivityName"].ToString().Contains(sSearch))  
        
                                        {  
        
                                            gvriParent.Add(griParent);   
        
                                        }           
        
                                    }  
        
                                }  
        
            ..........  
        
            if (iParentSearch < gvriParent.Count)  
        
                            {  
        
                                if ((gvriParent[iParentSearch] as GridViewExpandableRow) == null && ((gvriParent[iParentSearch].ParentOfType<GridViewExpandableRow>()))!=null)  
        
                                {  
        
                                    ((gvriParent[iParentSearch].ParentOfType<GridViewExpandableRow>())).IsExpanded = true;  
        
                                }  
        
                                gvriParent[iParentSearch].IsSelected = true;  
        
                                this.RadGridView1.BringDataItemIntoView(gvriParent[iParentSearch]);  
        
                                iParentSearch++;  
        
                            }  
        
            ......

the problem is
that if there is a scroll in my grid
the "foreach (GridViewRowItem griParent in RadGridView1.ChildrenOfType<GridViewRowItem>()) "
does not get the rows that are not shown in the screen

by the way
I use - this.RadGridView1.BringDataItemIntoView
but it looks like nothing happen

Thanks

Numeric Gauge Layouts

Hi

I've been using widly RadGauges in my application, which acts as a monitoring dashboard.

I have found how to create very stylish radial and linear gauges, but I'm not successed in Numeric ones.

How you something like layout examples of Numeric gauges that can be desined (if there will be code - that's would be great :))? (except those ones in demo project).

Maybe some links, or screenshots, or examples - any help in this would be very appreciated.

I'm probably looking for creating 3D-Look Numeric Gauge (already I've made so that the text in gauge has a 3D shadow) - is that possible?

Thanks

[Solved] RadPane Header Template

HowTo: Prevent Re-order of Grid Column

Hello,

I finally figured out how to prevent a user from re-ordering the first column in my grid.

Here's how I did it:

In the DataLoaded event of my grid I typed in this line (for the first column in grid):

((Telerik.Windows.Controls.GridView.GridViewDataControl)(sender)).Columns[0].IsReorderable = false;

What's kind of strange about this command is that I can't reorder the first column but I can move other columns in front of it. Here's what I did to prevent this problem:

In the ColumnReordered event of the grid I typed in the following lines of code:

private void ColumnReordered(object sender, GridViewColumnEventArgs e)

{

if (e.Column.DisplayIndex == 0)

for (int i = 1; i < gridname.Columns.Count ; i++)

if (e.Column.Header == gridname.Columns[i].Header)

e.Column.DisplayIndex = i;

}

Note. e.Column.DisplayIndex indicates where the user tried to move the column to.

If the user attempts to move a column to the position of the first column, the code above will search for the original location of the column being moved and set e.Column.DisplayIndex back to it's original value. Essentially I am moving the column back to its original location.

Custom Theme for NumericUpDown Control

Hi there
Is there any way to get the NumericUpDownControl to work from a custom theme dll?

I have created my own Custom theme for my Telerik control, and have applied it successfully to the Scheduler Control. Basically i want to style the numeric control so that the borders/arrow etc are my website colours rather than the standard orange. ( i wanted an application default rather than changing the style for each Numeric UpDown Control that i used).

I assumed it was a similar approach to the Scheduler Theming, i.e. if i altered the NumericUpDown.xaml in the Input folder of Themes, that these changes would be applied to the NumericUpDownControl, But i have made many colour changes, and none are applied to the control, i always see the default style.

Can anyone help me or point me in the right direction?
Is is possible to apply a custom theme to the NumericUpDownControl?

Thanks
Gillian

Roadmap for Q1 2010

Hi,

I've been tasting and working with RadControls_for_WPF_2009_3_1208_TRIAL,

And I wanted to know what items telerik going to focus, something like roadmap for 2010.

Any new controls?

Any new features for the current controls?

I've found a few things that in my opinion would be great if it will be in the next version:

1. Printing - print from major controls: grid, scheduler, tree...

2. Layout control - change view in runtime.

3. Grid View - Card View layout.

4. Grid View - Runtime change layout.

5. Themes for ALL standard controls, not by explicitly set to each control.

Keep on the good work!!

Thanks

Yohai
