I have several instances where I would like to have several controls in a single column in a datagrid.
For example, I have a dataset that contains images with matching description, image source, timestamp, geotag, etc. I would like to display this information with a thumbnail image in one column and the majority of data in either a textbox or a label. Other datasets I have require textbox / checkbox, or textbox / combobox.
When I attempt to add a second control I receive an error reporting that The property "VisualTree" is set more than once.
<DataGridTemplateColumn Header="Data" Width="100">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<Label Name="Description" Content="{Binding Desc}"></Label>
<Label Name="Camera" Content="{Binding Camera}"></Label>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
The DataTemplate should have only one element, I believe - so you should use a Panel to contain the elements, say something like this:
<DataGridTemplateColumn Header="Data" Width="100">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<Label Name="Description" Content="{Binding Desc}"></Label>
<Label Name="Camera" Content="{Binding Camera}"></Label>
</StackPanel>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
You could of course use WrapPanel, Grid, or anything else you like - StackPanel just appears to be what you're going for.
