WPF DataGrid ComboBox Column: Propagating Header Combobox throughout column...
- by LostKaleb
Hey there! Here's my question:
I've got a Datagrid in WPF and I have a first column that is a DataGridComboBoxColumn.
What I'd like to do is to have a header for that column also with a combobox: altering the header with propagate throughout the column.
I can get this done visually, but when I submit the data, the list that is bound with the Datagrid does not carry the new combobox values.
<dg:DataGridComboBoxColumn SelectedItemBinding="{Binding BIBStatus}"
ItemsSource="{Binding Source={StaticResource typeStatus}}"
Width="0.20*">
<dg:DataGridComboBoxColumn.HeaderTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="Built-In Bridge"/>
<ComboBox SelectedItem="{Binding BIBStatus}"
SelectionChanged="ComboBox_SelectionChanged"
ItemsSource="{Binding Source={StaticResource typeStatus}}"/>
</StackPanel>
</DataTemplate>
</dg:DataGridComboBoxColumn.HeaderTemplate>
</dg:DataGridComboBoxColumn>
In the ComboBox_SelectionChanged I have the following code:
DataGridColumn comboCol = this.gridResults.Columns[0];
for (int i = 0; i < this.gridResults.Items.Count; i++)
{
ComboBox myCmBox = (comboCol.GetCellContent(this.gridResults.Items[i]) as ComboBox);
myCmBox.SelectedValue = ((ComboBox)sender).SelectedValue;
}
When I submit the data, I submit the list that is DataContext to the Datagrid; if I change the value of the first column addressing a row at a time, i.e. clicking the cell with the combobox in each row, the values are propagated to the list in DataContext, however if I change the value of the first column by the header it does not.
Can anyone tell me what I'm missing? I'm guessing it's the way I affect each row, but I've tried SelectedValue, SelectedItem and SelectedIndex... all to no avail.
Thanks in advance...
