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

Custon Filter for RadGridview

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.

Asserting on RadComboItem's tooltip is not working as expected.

I tried getting tooltip value from comboitems using AutomationElement, it is giving 'RadComboBoxItem' as value of tooltip in all cases irrespectivie of value in tooltip.

Here is the sample application code:

<telerik:RadComboBox Height="17" HorizontalAlignment="Left" Margin="260,84,0,0" Name="StaticComboCtrl" VerticalAlignment="Top" Width="156" ItemsSource="{Binding}" RenderTransformOrigin="0.494,-1.5">
<telerik:RadComboBoxItem AutomationProperties.HelpText="ItemOne" ToolTip="ItemOne">Item1</telerik:RadComboBoxItem>
<telerik:RadComboBoxItem AutomationProperties.HelpText="ItemTwo" ToolTip="ItemTwo">Item2</telerik:RadComboBoxItem>
<telerik:RadComboBoxItem AutomationProperties.HelpText="ItemThree" ToolTip="ItemThree">Item3</telerik:RadComboBoxItem>
<telerik:RadComboBoxItem AutomationProperties.HelpText="ItemFour" ToolTip="ItemFour">Item4</telerik:RadComboBoxItem>
<telerik:RadComboBoxItem AutomationProperties.HelpText="ItemFive" ToolTip="ItemFive">Item5</telerik:RadComboBoxItem>
<telerik:RadComboBoxItem AutomationProperties.HelpText="ItemSix" ToolTip="ItemSix">Item6</telerik:RadComboBoxItem>
</telerik:RadComboBox>

Below is the code which gets autiomation element from point and gets "HelpText" property from that control.

System.Windows.Automation.AutomationElement testControl = AutomationElement.FromPoint(LocationOfTheCombItem or mouse position);

testing = testControl.Current.HelpText;

Here variable testing is always populated with value "RabComboBoxItem" but not actual value.

Any help would be highly appreciated in this regards.
