An item with the same key has already been added.

Can you shed any light on what would cause this issue? Typically, it will happen when I group or when I try to sort on a column.

I'm using the grid to display a set of search results, 10 columns in total. There will be duplicate values in some columns as some identifiers (customer / transaction IDs, etc) may appear multiple times. The grid is bound via MVVM to an ObservableCollection of objects via the DataContext. The columns are set up as attributes of those objects on first bind of the DataContext.

The data comes up fine on first load; then has issues when we sort or group.

RadTabItem Header Stretch

Is there a way, in XAML, to cause the tab item headers to stretch across the width of the tab control.

For example, I have three tabs, red, blue and green. I have a tab control with it's width set to auto, the tab headers will only fill up part of the space above the tab content, I want them to fill up all the space.

More specifically if I have 4 tabs I want last tab to take up the remaing space.

"Enter" key does not come out of the edit mode

Hello again,

I have another anoying bug in the GridView! With the following grid's XAML code:

    
            <telerik:RadGridView Grid.Row="1" Margin="0,5,0,5" Name="rgvAdministrativeAgent" xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" SelectionChanged="rgvAdministrativeAgent_SelectionChanged" AutoGenerateColumns="False" RowEditEnded="rgvAdministrativeAgent_RowEditEnded" ValidationMode="Row">  
        
                <telerik:RadGridView.Columns> 
        
                    <telerik:GridViewDataColumn Header="Name" DataMemberPath="Name" /> 
        
                    <telerik:GridViewDataColumn Header="Abbreviation" DataMemberPath="Abbreviation"  /> 
        
                </telerik:RadGridView.Columns> 
        
            </telerik:RadGridView>

When I start editing a row, everything is fine until I hit the "enter" key!

Then, the RowEditEnded event is launched as expected but when it ends, the row stay in edit mode! As long as I use the "enter" key, it will stop the edition mode and worse: it will relaunch each time the RowEditEnded event with a strange behavior because de e.newData stays the same as the first time the event was launched (even if data was modified before hitting "enter" key).

The only way to get out of this is to click anywhere else (wich launches also the RowEditEnded).

I don't know if it is normal, but I would expect the grid to stop editing the row when hitting "enter".
Is there any workaround?

Thanks,

Daniel

TabHeader Template

<TabItem.header>
<textBlock>ABC</textBlock>
</TabItem.Header>

When I am modifying Header template like this then it's not raising tab click event but when I click somewhere to end corners of tabheader.Event fires.I think It is something related with bubble events Which is not working when modifying header.

Please help me for this.

Cell Navigation

Hi,

The grid control looks good performance and feature wise.
However i was wondering how to switch on the cell-only/cell-row navigation (with keyboard) feature.

Can anybody suggest me on this?

Thanks,

Slider with small Width...

Hi.

I updated to Q2 2009 SP1 and now I have problem with small sliders (Width less than 56).
I use default theme (I think Office_black) and when I want to create slider with small Width it is not working right.

For example I want to do something like this:

myTestSlider = new Telerik.Windows.Controls.RadSlider();
myTestSlider.IsSnapToTickEnabled = true;
myTestSlider.TickPlacement = Telerik.Windows.Controls.TickPlacement.None;
myTestSlider.TickFrequency = 1;
myTestSlider.Focusable = false;
myTestSlider.Width = 34; // 8+20+6
myTestSlider.Minimum = 1;
myTestSlider.Maximum = 10;
Canvas.SetLeft(myTestSlider, 10);
Canvas.SetTop(myTestSlider, 10);
myTestCanvas.Children.Add(myTestSlider);

Slider Control has width 34 but its "internal" parts look and work like on width around 56 and so right part is not visible and goes beyond right border.
I don’t know if I am doing something wrong but currently I am not able to make small sliders.

Best regards,
Michal

How to populate Image in RadGridView by C# code

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)

{

if (e.Item is GridHeaderItem)

{

GridHeaderItem header = (GridHeaderItem)e.Item;

// to set the height of the Grid Header

header.Height = Unit.Pixel(20);

// to add an Image in the Grid Header

Image img=new Image();

img.ID = "Image1";

img.ImageUrl = "~/Image1.gif";

header["columnUniqueName"].Controls.Add(img);

}

}

Can anyone please let me know how to do above thing in WPF RADGRIDVIEW because radgridview dont have any event like ItemDataBound. I m also using Telerik.windows.control namaspace not Telerik.Web.UI.

Below is my Code

// I m adding Columns dynamically,

GridViewDataColumn IsUnRead = new GridViewDataColumn();
IsUnRead.Header = "R";
IsUnRead.UniqueName = "IsUnRead";
IsUnRead.Width = new GridLength(40);
this.gvEmail.Columns.Add(IsUnRead);

I want to have Image in header also dynamically by code.

Thanks in advance. Your view will be highly appreciated.

save/load radgridview settings, fix the example

I have seen several threads about this topic and all of them end with a reference to

http://blogs.telerik.com/vladimirenchev/posts/09-04-03/how_to_save_and_load_settings_with_radgridview_for_wpf.aspx

Unfortunately it is out of date, because it doesn’t work with the last Telerik release libraries version 2009.2.813.35. I have tried to fix but I can’t makes it works and serialize to save it. I feel like inventing the wheel!

Could someone from Telerik update it?
