Hi,
regards,
Juergen
- i have to bind a Textbox to a current cell.value (Excel-like Editbox behavior, if you type into a gridcell the typed char appears directly in the Textbox and vice-versa).
- UpdateSourceTrigger=PropertyChanged seems not to work with a gridcell.
- Text="{Binding ElementName=RadGridView1, Path=CurrentCell.Value} doesn't work ?
regards,
Juergen

Hi juergen,
Does your business object implements the INotifyPropertyChanged interface?
Please check our online demo about datasource change notifications.

Hello Veselin,
1.) yes, my viewmodel implements INotifyPropertyChanged.
2.) your example is not excactly the wanted behavior, because typed in chars appears on LostFocus of the cell/Textbox and
not as needed simultaneously like in Excel.
Sorry, I didn't found this similar behavior on your examples.

Hi juergen,
I managed to implement what you want only from the textbox to the cell, e.g. typing in the textbox updates the underlying property immediately. To make it the other way around - you need to redefine the CellEditTemplate.
Find attached a sample project.

Hello Veselin,
thank you for your proposal.
Your example is using a preconfigured xaml-declaration of the datatemplate:
But in my case i have to use a dynamic datacolumn creation:
The gridviewcolumn is created, only the Textboxoutline in the cell is drawn, but with no content.
Changing the celltemplate to textblock:
Content of MyViewModel is there (visible in editmode), also with desired effect, but not visible.
What I'm doing wrong?

Juergen

<Window.Resources>
<DataTemplate x:Name="SyncToBoxTemplate" x:Key="SyncToBoxTemplate">
<TextBox Text="{Binding UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}" />
</DataTemplate>
</Window.Resources>
But in my case i have to use a dynamic datacolumn creation:
private void AddGridViewDataColumn(string uniqueName)
{
GridViewDataColumn column = new GridViewDataColumn();
column.UniqueName = uniqueName;
column.Header = uniqueName; // LocalizationManager.GetString(uniqueName);
Binding bind = new Binding(uniqueName);
bind.Mode = BindingMode.TwoWay;
bind.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged;
column.DataMemberBinding = bind;
column.CellTemplate = (DataTemplate)FindResource("SyncToBoxTemplate");
grdView.Columns.Add(column);
Debug.WriteLine("Column: " + uniqueName + " added.");
}
The gridviewcolumn is created, only the Textboxoutline in the cell is drawn, but with no content.
Changing the celltemplate to textblock:
<Window.Resources>
<DataTemplate x:Name="SyncToBoxTemplate" x:Key="SyncToBoxTemplate">
<!--<TextBox Text="{Binding Name, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}" />-->
<TextBlock></TextBlock>
</DataTemplate>
</Window.Resources>
Content of MyViewModel is there (visible in editmode), also with desired effect, but not visible.

Hi juergen,
Do you set the Path of the Binding of the TextBox when a cell is selected as I do in my test project?

Hi Veselin,
this part is also active:
this part is also active:
private void grdView_SelectedCellsChanged(object sender, GridViewSelectedCellsChangedEventArgs e)
{
GridViewCellInfo ci = e.AddedCells[0];
Binding b = new Binding((ci.Column as GridViewDataColumn).DataMemberBinding.Path.Path)
{
Mode = BindingMode.TwoWay,
UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged,
Source = ci.Item
};
txtContent.SetBinding(TextBox.TextProperty, b);
}
There's a kind of switching bind, on creation of the column and when SelectCellsChanged-event is raised.
But I don't see how to resolve this.
Thank you for your help.
regards,

Hello juergen,
I am not sure what went wrong in this case. Can you please prepare a sample project (or just modify the one I sent you) which demonstrates the problem? You have to attach it in a new support ticket as a zip archive.
Thanks
