I am experiencing some problems making AccessKeys work the way I understand they should in a RadRibbonView.

I have a sample application to demonstrate the problem, but I do not know how to make it available. When the application is running, pressing Ctrl+D should activate the click event of a RadRibbonButton. Note that I configure the AccessKeys property in the initialized event of the button as follows:

private void RadRibbonButton_Initialized(object sender, EventArgs e)

{

((RadRibbonButton)sender).SetValue(KeyTipService.AccessKeysProperty, new Collection<KeyGesture>() { new KeyGesture(Key.D, ModifierKeys.Control) });

}

This is my xaml code for the ribbon:

<telerik:RadRibbonView Grid.Row="0" VerticalAlignment="Top" Grid.ColumnSpan="2" telerik:KeyTipService.IsKeyTipsEnabled="true">

<telerik:RadRibbonTab Header="RibbonTab" telerik:KeyTipService.AccessText="R" >

<telerik:RadRibbonGroup>

<telerik:RadRibbonButton telerik:KeyTipService.AccessText="H" telerik:KeyTipService.AccessKey="Ctrl+D" Click="RadRibbonButton_Click" Text="Test" Initialized="RadRibbonButton_Initialized" />

</telerik:RadRibbonGroup>

</telerik:RadRibbonTab>

</telerik:RadRibbonView>

What can I do to get this working?

[Solved] RadDocking AutomationId

Hi,

We are using RadDocking with Caliburn Micro and view model first approach. Inside factory we create view models which are resolved by Caliburn Micro. Recently we found that we don't really know how to add AutomationId (or any other name to dynamically loaded views). Is there any proven way to solve this issue?

RadDocking is declared the following way:

<telerik:RadDocking x:Name="radDocking" AutomationProperties.AutomationId="radDockingId" DockingPanesFactory="{Binding PanelsFactory}" PanesSource="{Binding Panes}"

Have a nice day,

Best regards,

Maciek

RadNumericUpDown acepts comma AND dot

Hello,

I want to know if is it possible to do that RadNumericUpDown accepts dot AND comma ?

I see this code on the web :

if (e.KeyChar.Equals('.') || e.KeyChar.Equals(','))

{

e.KeyChar = ((System.Globalization.CultureInfo)System.Globalization.CultureInfo.CurrentCulture).NumberFormat.NumberDecimalSeparator.ToCharArray()[0];

}

With this code, i did it :

private void tbOpeSurValeur_KeyDown(object sender, KeyEventArgs e)

{

if (e.Key == Key.Decimal || e.Key == Key.OemComma)

{

e.Key = (Key)((System.Globalization.CultureInfo)System.Globalization.CultureInfo.CurrentCulture).NumberFormat.NumberDecimalSeparator.ToCharArray()[0];

}

But, 2 problems :
- This is not 'e.KeyChar' but 'e.Key'
- 'e.Key' is in ReadOnly, I can't change his value..

Can you help me ?
Thank you.

Valentin.

Using RADNumericUpDown

Hello everybody!
My radnumericcontrols have a strange behaviour . For example : if i insert the value 20, when the control lost focus, the value is set to 200%, wich isn't the correct value, at least the value I want. There is another issue here . What is the default decimal separator ?If I try to use the normal "comma", nothing happens . If I insert the value "10,23", the control doesn't accept my comma , so, instead of having the value "10.23", I get the value 1023 .

Any suggestions ?

Adding new row to top of grid

Is it possible to add a new row to edit to the top of the grid instead of the bottom? I was able to sort after adding the new item to get the last added item to display at the top, but I want to be able to have the new row be at the top immediately after clicking to add the new row while editing.The image attached shows how the GridView works now, but I want to be able to have the new row to be at the top of the grid while editing. Any help would be appreciated.

expanding a certain row

Hi,

i understand that when a new row is added somewhere in the tree, the new row is added to the bottom.

to get around this i re-bind the tree to the update source, and am now trying to see if i can expand to the part of the treelistView where the new item it located.

i can interactively expand to the spot in the tree and find the newly created row.

the customer does not want to do this however as there may be too much data.

i need a way to do this in the code-behind.

is there a way?

Thanks in advance,

John

I want to have custom filter like the default fulltext search auf RadGridview. But I want to filter with custom expression that I definied.

For that purpose I look at first for a pssibility to override the FilterDescriptor of the default fulltext search. But I have no luck.

I can accept an "external" textbox that can raise a filter condtion on the RadGridview as well. Any suggestions?

How to refresh cell value?

I have a grid with two columns, one of which is editable and another is readonly, set programmatically based on first column value:

    
                                <t:RadGridView x:Name="NetworkLocationGroupsGridView" CanUserFreezeColumns="False" ShowGroupPanel="False" ItemsSource="{Binding NetworkLocations}" AutoGenerateColumns="False" ShowInsertRow="True" IsFilteringAllowed="False" CanUserReorderColumns="False" RowIndicatorVisibility="Collapsed" CellValidating="NetworkLocationGroupsGridViewCellValidating" CellEditEnded="NetworkLocationGroupsGridView_CellEditEnded" EditTriggers="CellClick">  
        
                                    <t:RadGridView.Columns> 
        
                                        <t:GridViewDataColumn DataMemberBinding="{Binding Id}" Header="Id" Width="50" /> 
        
                                        <t:GridViewDataColumn DataMemberBinding="{Binding LongName}" Header="Name" Width="340" IsReadOnly="True" /> 
        
                                    </t:RadGridView.Columns> 
        
                                </t:RadGridView>

In CellValidating event handler, when first column value changes, I calculate and set the value of the second column:

    
                            int id = (int)e.NewValue;  
        
                            var dataTable = dataAccess.GetDataTableFromStoredProcedure("ManagementGetLocationDetail", new Dictionary<string, object> { { "networkLocationId", id } });  
        
                            ((GridViewCell)e.Row.Cells[1]).Value = dataTable.Rows[0]["LongName"].ToString();  
        
                            e.IsValid = true;

or

    
                            int id = (int)e.NewValue;  
        
                            var dataTable = dataAccess.GetDataTableFromStoredProcedure("ManagementGetLocationDetail", new Dictionary<string, object> { { "networkLocationId", id } });  
        
                            var networkLocation = (NetworkLocation)e.Row.Item;  
        
                            networkLocation.LongName = dataTable.Rows[0]["LongName"].ToString();  
        
                            e.IsValid = true;

But even though the second cell value changes, the visual representation stays unchanged, the grid still displays the original cell value. I need the second cell to visually change immediately after first cell passes validation, but I can't find any suitable methods or events to do that. I've tried e.GridViewDataControl.Items.Refresh() but it doesn't work.
