推荐答案

您可以使用面板.将datagrid控件放入面板中.

现在在datagrid的cellclick上

将面板显示为弹出窗口，然后在面板上放置更新按钮.在datagrid中选择一行后，该特定行的所有数据将在面板控件上.当用户单击更新按钮更新表并绑定数据网格时选择主题.

you can use a panel. put your controls of datagrid into panel.

now on cellclick of datagrid

show your panel as popup and put update button on panel. After selecting a row in datagrid all data of that particular row will be on panel controls. after selecting subject when user clicks on update button update table and bind datagrid.

<datagrid name="dgSales" height="300" margin="0,3,0,0" issynchronizedwithcurrentitem="True" selecteditem="{Binding SelectedItem,Converter={StaticResource ignoreNewItemPlaceHolderConverter}}" itemssource="{Binding StockList,UpdateSourceTrigger=PropertyChanged}" tooltip="{Binding RelativeSource={RelativeSource Self},Path=(Validation.Errors)[0].ErrorContent}" gotkeyboardfocus="dgSales_GotKeyboardFocus" currentcellchanged="dgSales_CurrentCellChanged" previewkeydown="dgSales_PreviewKeyDown">
	<datagrid.columns>
		<datagridtextcolumn header="S No." width="SizeToCells" minwidth="60" binding="{Binding SNo}" isreadonly="True" />
		<datagridtemplatecolumn header="Stock Name" width="280">
			<datagridtemplatecolumn.celltemplate>
				<datatemplate>
					<textblock text="{Binding StockName}" />
				</datatemplate>
			</datagridtemplatecolumn.celltemplate>
			<datagridtemplatecolumn.celleditingtemplate>
				<datatemplate>
					<combobox width="280" name="cmbStock" itemssource="{Binding Path=Stocks}" focusmanager.focusedelement="{Binding RelativeSource={RelativeSource Self}}"></combobox>
				</datatemplate>
			</datagridtemplatecolumn.celleditingtemplate>
		</datagridtemplatecolumn>
		<datagridtextcolumn header="Unit Price" width="SizeToCells" minwidth="80" binding="{Binding UnitPrice,UpdateSourceTrigger=LostFocus}" />
		<datagridtextcolumn header="Unit" width="SizeToCells" minwidth="80" binding="{Binding Unit}" isreadonly="True" />
		<datagridtextcolumn header="Quantity" width="SizeToCells" minwidth="80" binding="{Binding Quantity,UpdateSourceTrigger=LostFocus}" />
		<datagridtextcolumn header="Discount" width="SizeToCells" minwidth="80" binding="{Binding Discount,UpdateSourceTrigger=LostFocus}" />
		<datagridtextcolumn header="Amount" width="SizeToCells" minwidth="100" binding="{Binding Amount,StringFormat=\{0:n2\}}" isreadonly="True" />
	</datagrid.columns>
</datagrid>
