DataCell ReadOnly="True" do not disables entering to edit mode

Daniel — Wed, 30 Nov 2011 07:37:16 GMT

I need to have some Cells in grid to be ReadOnly and some to be editable. I have found that settings property ReadOnly="True" for DataCell has no influance, and there is still posiible to edit content of cell (for test I use default editor). I use Style like this
<Style TargetType="{x:Type xcdg:DataCell}">

<Setter Property="ReadOnly" Value="True" />
<Style.Triggers>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource Self}, Path=ReadOnly}" Value="True">
<Setter Property="Background" Value="Red" />
</DataTrigger>
</Style.Triggers>

</Style>

to set ReadOnly for all DataCells (just for test purposes), but only background color changes to red (to confim that ReadOnly is true), but there is still possible to open cell editor and edit value in cell. It looks that only Column ReadOnly can disable editing (but for whole column as expected) or DataGridControl.

What I'm doing wrong?

Editor for MVVM ComboBox custom type

Jean-François — Thu, 01 Sep 2011 19:10:57 GMT

Hi,

I've created a class called Choices that represent a ComboxBox. Choices has public List and Value properties to bind a combo box (list of choices and selected value).

I want to bind a column of the grid on a property returning an instance of this object and I want the editor of a cell to display a working ComboBox based on those binding.

I've binded the ComboBox DataContext on the CellEditorBinding (which points to the a Choices instance) and I've binded both the list and value property. I can't seem to get the editor to display the cell won't let itself be edited and I know my binding should work since the ComboBox binding are working great on ComboBoxes when they are not in a cell editor.

What am I doing wrong ? Why can't I use the editor ? I get no binding errors at all !

Edit datagrid cell based on condition

hiren — Wed, 29 Jun 2011 15:51:13 GMT

Hi Guys,

I am using 3.7 wpf datagrid control.

I have a bound datagrid control with four columns. First column is checkbox, 2nd is read only and 3rd & 4th are editable columns with textbox editor.

Now I want user to allow cell of 3rd & 4th columns only if checkbox is checked in first column.

I don't want to user to start editing values in 3rd and 4th columns without selecting checkbox field.

Any idea? how can I achieve this?

i tried implementing checkbox template and handling checkbox checked event as folllow:

private void CheckBox_Checked(object sender, RoutedEventArgs e)

{

DataRow dr = mygrid.GetContainerFromItem(mygrid.CurrentItem) as DataRow;

if (dr != null)

{

Cell cel = dr.Cells[2];

if (cel != null)

{

cel.ReadOnly = false;

cel.BeginEdit();

}

}

}

but I am getting below error as I kept columns read only

"An attempt was made to edit a read-only cell or the cell content is not bound using two way binding."

Thanks

Bug with DatePickerEditors

Grégoire — Fri, 17 Jun 2011 10:53:23 GMT

Hello,

I'am using version 4.2.11215.9190 of DataGrid with EntityFramework and I'am facing issues with CellEditor.DatePickerEditor in the DataGridControl and TableView.

- In Edit mode, the drop down picker never show when i hit the button.

- Zeros are not shown on single numbered dates and presentation is different between Edit Mode and non Edit Mode. To illustrate that point I attached a picture of what it looks like on my screen.

Are these issues known? Should I make my own DatePicker for your DataGrid?

Re: Foreign key value assignment

Troy — Fri, 20 Aug 2010 07:07:29 GMT

I recently upgraded to 3.7 and still couldn't get this to work easily. I did eventually though but I think not through the ForeignKeyConfiguration property.

I had to jump through several hoops to get it working. Here is how I did it.

PARTIAL CollectionViewSource

<xcdg:DataGridCollectionViewSource
        x:Key="cvs_jobs"
        AutoCreateDetailDescriptions="False"
        AutoCreateForeignKeyDescriptions="True"
        AutoCreateItemProperties="False"
        AutoFilterMode="And"
        DefaultCalculateDistinctValues="False"
        DistinctValuesConstraint="Filtered"
        Source="{Binding Path=Jobs}">
        <xcdg:DataGridCollectionViewSource.ItemProperties>
          <xcdg:DataGridItemProperty
            Name="JobID"
            DataType="{x:Type s:Int32}"
            IsReadOnly="True"
            Title="Job #"
            ValuePath="JobID"/>
          <xcdg:DataGridItemProperty
            Name="QuoteID"
            DataType="{x:Type s:Int32}"
            IsReadOnly="True"
            Title="Quote #"
            ValuePath="Quote"/>
          <xcdg:DataGridItemProperty
            Name="Product"
            CalculateDistinctValues="True"
            DataType="{x:Type local:Product}"
            IsReadOnly="False"
            Title="Product"
            ValuePath="Quote1.Product1"/>
          <xcdg:DataGridItemProperty
            Name="Customer"
            CalculateDistinctValues="True"
            DataType="{x:Type local:Customer}"
            IsReadOnly="False"
            Title="Customer"
            ValuePath="Quote1.Customer1"/>

PARTIAL DataGridControl

<xcdg:DataGridControl
      Name="JobDataGrid"
      AutoCreateColumns="True"
      AutoCreateDetailConfigurations="True"
      AutoCreateForeignKeyConfigurations="True"
      CellEditorDisplayConditions="CellIsCurrent"
      ItemsSource="{Binding Source={StaticResource cvs_jobs}}"
      NavigationBehavior="RowOrCell"
      UpdateSourceTrigger="CellEndingEdit">
      <xcdg:DataGridControl.Columns>
        <xcdg:Column FieldName="JobID" IsMainColumn="True"/>
        <xcdg:Column FieldName="QuoteID"/>
        <xcdg:Column FieldName="Product"/>
        <xcdg:Column FieldName="Customer" VisiblePosition="3">
          <xcdg:Column.CellContentTemplate>
            <DataTemplate DataType="{x:Type local:Customer}">
              <StackPanel Orientation="Horizontal">
                <TextBlock Text="{Binding CustomerName}"/>
                <TextBlock Text=" ("/>
                <TextBlock Text="{Binding AccountCode}"/>
                <TextBlock Text=")"/>
              </StackPanel>
            </DataTemplate>
          </xcdg:Column.CellContentTemplate>
          <xcdg:Column.ForeignKeyConfiguration>
            <xcdg:ForeignKeyConfiguration DisplayMemberPath="CustomerName" ItemsSource="{Binding Source={StaticResource cvs_customers}}" ValuePath="."/>
          </xcdg:Column.ForeignKeyConfiguration>
          <xcdg:Column.CellEditor>
            <xcdg:CellEditor>
              <xcdg:CellEditor.EditTemplate>
                <DataTemplate DataType="{x:Type local:Customer}">
                  <ComboBox
                    DisplayMemberPath="CustomerName"
                    ItemsSource="{Binding Source={StaticResource cvs_customers}}"
                    SelectedItem="{xcdg:CellEditorBinding}"
                    SelectedValue="."
                    SelectedValuePath="."/>
                </DataTemplate>
              </xcdg:CellEditor.EditTemplate>
            </xcdg:CellEditor>
          </xcdg:Column.CellEditor>
        </xcdg:Column>
      </xcdg:DataGridControl.Columns>

And now I simply call LinqDataContext.SubmitChanges and it works! I also have the benefit of the editor selecting the correct line in the combobox when beginning edit (which I have seen posts about). I have left my ForeignKeyConfiguration there but I suspect I could delete it. It seems that ForeignKey detection just doesn't work for Linq2Sql but setting a CellContentTemplate and a clever CellEditor seem to do the trick.

Re: How to make some particular cells in grid as read only?

Nagaraju — Fri, 02 Jul 2010 12:58:08 GMT

hi derek

It is working it's fetching me the cell value and here is the code which works fine for making some particular cells as read only

<xcdg:DataGridControl.Resources>

<local:OutturnReadOnlyConverter x:Key="OutturnReadOnly"/>

</Style>

</xcdg:DataGridControl.Resources>

and the front end code looks like this

public class OutturnReadOnlyConverter:IValueConverter

{

#region IValueConverter Members

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

{

DataCell objDataRow = (DataCell)value;

if(objDataRow.HasContent)

{

if (objDataRow.Content.ToString() == "-99")

return true;

}

return false;

}

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

{

return null;

throw new Exception("The method or operation is not implemented.");

}

#endregion

How to make some particular cells in grid as read only?

Nagaraju — Thu, 01 Jul 2010 05:54:27 GMT

here is the code which i was trying to achieve to make some particular cells as read only.I used a converter class which i defined in the

when i am using this code in my project it is setting the whole row to readonly...........

public class OutturnReadOnlyConverter:IValueConverter

{

#region IValueConverter Members

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

{

if (value != null)

{

DataRow objDataRow = (DataRow)value;

for (int i = 0; i < objDataRow.ItemArray.Length;i++)

{

string strValue = objDataRow.ItemArray.ToString();

if (strValue == "-99")

return false;

}

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

return null;

throw new Exception("The method or operation is not implemented.");

Can anyone help me out regarding this issue?

How can I change the background/foreground color of a cell being edited?

Morgan — Tue, 02 Feb 2010 18:30:55 GMT

I am new to Xceed. I have searched the forum, but could not find out how can I change the background / foreground color of a cell being edited.

I have tried the following but the color does not change:

      Dim numericEditor As New NumericEditor
      Dim numericTextBox As WinNumericTextBox = numericEditor.TemplateControl
      numericTextBox.BackColor = Color.Yellow
      GridControl1.Columns.Add(New Column("UnitCost", GetType(Single)))
      GridControl1.Columns("UnitCost").CellEditorManager = numericEditor
