hi!

I developed a UserControl with a RadComboBox and RadMaskedTextBox, snippet code is like this:


into my main project I declared UserControl like this:


I declared 2 dependency properties into My UserControl named ValorTipoDocumento and ValorNumeroDocumento in this way:

I hope so far It could have be understood!! I try to make clear at the most.

I bounded my UserControl to the radGridView by using the two properties I created to refelct changes in both way. 

Note: <Binding ElementName="grdGridConsulta" Path="SelectedItem.CA003" Mode="TwoWay" AND
<Binding ElementName="grdGridConsulta" Path="SelectedItem.CA004" Mode="TwoWay"

When I navigate into RadGridView (I mean, selectedItemChanged is fired), UserControl reflects the changes in right way (I mean radComboBox and radMaskedTextBox). PROBLEMS begin when I select other item into radComboBox and I change text into radMaskedTextBox, and I try to update source data in RadGridView, by using:

ctrDatosPersona.GetBindingExpression(ctlIdentificacionPersona.ValorTipoDocumentoProperty).UpdateSource();
ctrDatosPersona.GetBindingExpression(ctlIdentificacionPersona.ValorNumeroDocumentoProperty).UpdateSource();

Data are null. RadGridView shows empty data into corresponding cells. I try to do a trace and ctrDatosPersona doesn't return selected values and text changed, in fact, returns  {} for ValorTipoDocumento and nothing for ValorNumeroDocumento. The way I realized about this was by tracing ValidationRules values.

I don't know how to do to radGridView reflects changes from my UserControl.

It's urgent, any helps I appreciate

Hi!

I have a details panel that show item selected from radgridview. Main DataContext = DataTable.DefaultView named VistaDatos. GridView is like this:


In details panel I have some controls, most important this:


ItemsSource code is CA001, ItemsSource Description si CA003 in radComboBox,  When I Update source radgridView, binding works fine, but I don´t know how to do to udpate description or text from radComboBox to this gridViewDataColum: 

<telerik:GridViewDataColumn Header="{x:Static resx:resxUsuarios.lblNivelDescrip}" DataMemberBinding="{Binding CA006_DESCRIPCION, Mode=TwoWay}" UniqueName="CA006_DESCRIPCION" HeaderCellStyle="{StaticResource GridViewHeaderCellStyle1}" HeaderTextAlignment="Center"/>

I tried something like this:


but it doesn´t work.

Can you help me about this???

thanks

Hi,
I am adding 2  DataSeries into DefaultView.ChartArea, but only one of them shown in a time.
How I can show, data series together in a time in one rad chart ?


Thanks

Hello Telerik,

I have a few problems with the chart.
Attached NO example. (!! we are unable to attach zip files)

Flickering:
When i set the 'DefaultView.ChartArea.AxisY.AutoRange' to TRUE, the chart flickers,
when set it to FALSE and specify the min/max/step value it does not have this problem,
but .... i would like to use the AutoRange function :)

Horizontal scroll/zoom:
- I cannot get this working, i think when setting the min/max values for the X axis, everything is reset?
  Is there a solution for this behavior?
- When i start the application and press ALT-F4 (to close the application), it works,
  when i first try to scroll/zoom the horizontal bar (or clicking on the slider), i cannot press ALT-F4 again, or any other common keyboard shortcuts.

With kind regards,
Rob

As we are unable to attach ZIP files, here the .cs code for the window (it only has one radchart)

Window.xaml


Window.xaml.cs

How do I change the celltype/celledittype on autogenerated columns?
I've done the following but it doesn't work.  It assigned the template, but doesn't seem to display the template.

private void fullyLoadedCostListRadGridView_AutoGeneratingColumn(object sender, GridViewAutoGeneratingColumnEventArgs e) {
    e.Column.CellTemplate = (DataTemplate)FindResource("telerikContentColumnTemplate");
}

I am editing a row in a RadGridView (WPF -- form application). I want to use the CellEditEnded event, when they are done editing a particular cell, I want to move the focus back to a textbox on the form. When the user hits Tab the CellEditEnded event fires and that seems to be the even to use.

I can trap for the column and when I call txtProductCode.Focus(); nothing happens. When I hit tab again the next cell in the same grid row has focus. So it is behaves like it needs to 'leave' the grid first.

Any thoughts?

Hello,

We are binding a RadGridView to a property (Observable Collection of Entities) in an MVVM scenario. Within this grid we have a GridViewCheckBoxColumn that has a DataMemberBinding to a string property within our entities. Since the string is always "0" or "1" we use a ValueConverter to convert to Boolean - True/False in order to tick the checkbox. We found that the converter always calls the "Convert" method instead of the "ConvertBack" upon setting the value....

For test purposes we were binding a standard GridViewDataColumn to the same converter to ensure it is working properly which it does....

Example:

Now, when we change the value in the GridViewDataColumn the "ConvertBack" method is correctly (as expected) invoked....

When we do the same (ticking / unticking the checkbox on the GridViewCheckBoxColumn) it always calls the "Convert" method.....

Clearly that can't be right.... can you guys please help!

Many Thanks in advance.....

Regards

This works (default Microsoft toolbar):

        <ToolBar ItemsSource="{Binding Path=Actions}"></ToolBar>

This does not:

        <telerik:RadToolBar ItemsSource="{Binding Path=Actions}"></telerik:RadToolBar>

What i get is number of items x 2 when the toolbar is shown.

I notice that there are multiple questions revolving around this issue, but they are old. Is this still a problem in Telerik WPF controls, or am I missing something?

I'm trying to force the row details presenter of my grid to be the full width of its parent row. This has actually has two parts to it. All my grids seem to have a column at the far left of the grid that I can't seem to remove. After that the grid in my row details seems to only take up as much room as it needs, it never expands to the space available. Its a bit difficult to explain so I've attached a screen shot of my problem. Hopefully someone can point me in the right direction!

Thanks
