Hi,

In my case the number of columns (textcolumns not combobox columns) vary.
Is this case posible to render using xamwebgrid. If it is then can you please post the code
or attach the entire code for doing the same. In the sample code that you have provided
the textblock binds to a specific property. But in my case the property has to be dynamic.

Hello!

Thank you for help.

1. static resources is best solution for known count of the combobox columns...

But what about if I don`t know how many combobox colums I should create?

2. What about events of the controls within DataTemplate when I create it use XamlReader.Load?

As I see, the xamwebgrid is not able for dynamic structure of the data presetation. The XamWebGrid is ready for static structure, but dynamic is not?

Are you planing the combobox column?

Maby you planing some advance xamwebgrid for REALLY dynamic stucture of the data like  Infragistics grid control for win forms?

Thank you

Hi, 

So, the best way to get an ItemSource, that should be calculated dynamically set in a DataTemplate, is to use an IValueConverter. 

Where you'd have something like:

<DataTemplate>

     <ComboBox ItemSource="{Binding Converter={StaticResource myComboValueConverter}}"/>

</DataTemplate>

Then in your IValueConverter, you'd  look at your data object, and return an IEnumerable of the data that should be displayed in the combo. 

I hope this helps,

Hello!

I`ve found the great problem when I add the combobox into the EditTemplate: 

1. I cannot fill the combobox ItemsSource 

2. events of this combo is not fire (Loaded event, for example).

3.I cannot get reference to this combo.

I am use the XamlReader to create the  DataTemplate (ItemTemplate, EditTemplate, HeaderTemplate) object (as in previouse posts).

Maby possible get reference to this combo in any event of xamwebgrid and fill it by the data and make events?

How to solve this problem? Maby you have any workaround for this?  This problem makes me crazy.

I am really need your help. Thank you.

Thank you Stephen!

Last post is really helpful!

Here the sample for other developers, who looks for it.

    TemplateColumn CreateDataPickerTemplate(string Header, string bindingProperty, bool EditTemplate, bool HeaderTemplate)
        {
            TemplateColumn tcolumn = new TemplateColumn();
            tcolumn.HeaderText = Header;
            tcolumn.Key = bindingProperty;

            StringBuilder ItemTemplate = new StringBuilder();
            ItemTemplate.Append("<DataTemplate");
            ItemTemplate.Append(" xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\" ");
            ItemTemplate.Append(" xmlns:x=\"http://schemas.microsoft.com/winfx/2006/xaml\"");
            ItemTemplate.Append(" xmlns:igGrid=\"clr-namespace:Infragistics.Silverlight.Controls;assembly=Infragistics.Silverlight.XamWebGrid.v9.1\"");
            ItemTemplate.Append(" xmlns:controls=\"clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls\"");
            ItemTemplate.Append(" >");
            ItemTemplate.Append("<TextBlock Text=\"{Binding ");
            ItemTemplate.Append(bindingProperty);
            ItemTemplate.Append(" }\"></TextBlock>");
            ItemTemplate.Append(" </DataTemplate>");

            tcolumn.ItemTemplate = (DataTemplate)XamlReader.Load(ItemTemplate.ToString());

            tcolumn.HeaderTemplate = (DataTemplate)XamlReader.Load(ItemTemplate.ToString());


            if (EditTemplate)
            {
                StringBuilder EditorTemplate = new StringBuilder();
                EditorTemplate.Append("<DataTemplate");
                EditorTemplate.Append(" xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\" ");
                EditorTemplate.Append(" xmlns:x=\"http://schemas.microsoft.com/winfx/2006/xaml\"");
                EditorTemplate.Append(" xmlns:igGrid=\"clr-namespace:Infragistics.Silverlight.Controls;assembly=Infragistics.Silverlight.XamWebGrid.v9.1\"");
                EditorTemplate.Append(" xmlns:controls=\"clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls\"");
                EditorTemplate.Append(" >");
                EditorTemplate.Append("<controls:DatePicker SelectedDate=\"{Binding ");
                EditorTemplate.Append(bindingProperty);
                EditorTemplate.Append(" }\"></controls:DatePicker>");
                EditorTemplate.Append(" </DataTemplate>");

                tcolumn.EditorTemplate = (DataTemplate)XamlReader.Load(EditorTemplate.ToString());

            }

            return tcolumn;
        }

 this.ZSheet.Columns.Add(CreateDataPickerTemplate("myHeader", "DateTime_field", true, true));
            ColumnLayout cl = new ColumnLayout(this.ZSheet);
            cl.Key = "DateTime_field1";
            cl.Columns.Add(CreateDataPickerTemplate("myHeader", "DateTime_field1", true, true));
            this.ZSheet.ColumnLayouts.Add(cl);

Onse again thank you!
