DataFormatString

Hi guys,

I've set up some columns which are of Decimal data type with a data format string which converts these decimals values to a percentage between 0 - 100% ie. DataFormatString = "{0.0.00\\%}". The problem I am having is a few of these rows do not need to have the data format string on them, they should be left as they are. I've had a look at conditional formatting with Converters with the ContentStringFormat but can't get this to work (I believe because the data type is decimal?). I am using the decimal type because this helps with validation (only numerics). Otherwise, what's the best method to implement this?

Thanks!

Tim.

This is the code I used for the converter:

XAML

<

telerikGrid:RadGridView.Resources>

<Client:ValueConverter x:Key="ValueConverter"/>

</Style>

</telerikGrid:RadGridView.Resources>

Binding Path=Period is a <BindingList> of Decimals so 'object value' returns an array of objects, which I have to extract. Basically my goal is to overwrite (or bypass) the DataFormatString in the GridViewDataColumn for a few rows - if this is possible.

Converter Class

public

object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)

{

//if (a[0] > 100)

return "{0:0.00}";

//return Binding.DoNothing;

}

Custom row template with editable cells

Hello.
I evaluate GridView and try to use custom row layout as it showed in GridView/CustomRowLayout.
I created ControlTemplate and placed GridViewCell for every column. But these cells is not editable, have gray background color and do not use expected representation (for example boolean property is diplayed as True/False string instead of checkbox).
How to display cells as they are displayed without any custom row layout?

Insert Image in to cells on selected rows

Hi,

How Can I set a image in to specific cell on all selected rows.

i tried something like this:

foreach (MyObject obj in MyGrid.SelectedItems)

{

System.Windows.Controls.Image image = new System.Windows.Controls.Image();

image.Source = new BitmapImage(new Uri(@"[...]"));

((MyObject)MyGrid.SelectedItem).myImage= image;

}

the problem with this code is that the last row is the only row effected.

issues with q3 and group totals alignment.

hello all,

i upgraded to q3 version. however, since then, i am having problems with scrolling. though i have set scrolling to realtime, it does not behave so. also the form hangs or freezes very often and whenever its refreshed.

is this a known behaviour?

since i was having troubles with q3, i downgraded to q2 - 2009.2.813.35

i am trying to align group totals to left hand side. i am pasting part of the code here. however, i still donot get group totals on the left hand side. i know that q3 has fixed this issue but becoz of above mentioned issues, i am unable to use them.

<Window.Resources>

</Style>

</Window.Resources>

Group Footer Widths

The GroupFooters appear not to be correctly updating their width all the time.
ie. Grab the ColumnHeader sizing thumb and drag it narrower, and the GroupFooter doesn't change to match. Dragging it wider however, appears to work.

I've tested with last release 2009.3.1103.35 and 2009.3.1120.35

There was nothing special in my XAML, just showing columns automatically.

    
            <telerik:RadGridView xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"   
        
                        ShowGroupFooters="True" 
        
                        x:Name="uxRadGridView">  
        
            </telerik:RadGridView>

BeginInsert does not insert a new row

The grid is 2009 Q2.
Grid.ItemSource = dataTable.

private

void btnAdd_Click(object sender, RoutedEventArgs e)

{

Grid.BeginInsert();
}

Is it because the dataTable has a few primary keys?

How do I resolve this?

Thanks
