私はwpfアプリケーション用にtelrikRadGridViewを使用しています。グリッドをSQLデータベースにあるテーブルにバインドしたいと思います。かなり簡単だと思いましたが、あまり運が良くありません。SQLデータを取得し、適切に入力されているDataSetに保存しています。ただし、画面に表示されるのは、データが入力されていないテーブル列だけです。RadGridViewのXAMLは次のとおりです。
<telerik:RadGridView Name="Grid" Grid.Row="2" Grid.ColumnSpan="3" HorizontalAlignment="Center" VerticalAlignment="Bottom"
AlternateRowBackground="AliceBlue" SelectionMode="Multiple"
AutoGenerateColumns="False" MinHeight="300" MinWidth="800" CanUserResizeColumns="True" CanUserResizeRows="True"
FilteringMode="FilterRow" IsFilteringAllowed="True" CanUserSortColumns="True" GridLinesVisibility="Both"
DataLoadMode="Asynchronous" >
<telerik:StyleManager.Theme>
<telerik:Windows8Theme/>
</telerik:StyleManager.Theme>
<telerik:RadGridView.Columns>
<telerik:GridViewDataColumn Width="40" Header="Add" DataMemberBinding="{Binding Add}" IsGroupable="False" IsFilterable="True" >
</telerik:GridViewDataColumn>
<telerik:GridViewDataColumn Width="75" Header="Qty" IsGroupable="False" IsFilterable="True">
</telerik:GridViewDataColumn>
<telerik:GridViewDataColumn Width="75" Header="ID" DataMemberBinding="{Binding ID}" IsGroupable="False" IsFilterable="True"/>
<telerik:GridViewDataColumn Width="200" Header="Description" DataMemberBinding="{Binding Description}" IsGroupable="False" IsFilterable="True"/>
<telerik:GridViewDataColumn Width="75" Header="Price" DataMemberBinding="{Binding Price}" IsGroupable="False" IsFilterable="True"/>
<telerik:GridViewDataColumn Width="75" Header="Min" DataMemberBinding="{Binding Min}" IsGroupable="False" IsFilterable="True"/>
</telerik:RadGridView.Columns>
</telerik:RadGridView>
csコードでは、データセットを入力し、データコンテキストをグリッドに設定しています。
Grid.DataContext = ds.Tables[0].DefaultView;
私はまだWPFプログラミングに慣れていないので、ここでマイナーな何かが欠けているのか、それとも単に不可能なことをしようとしているのかわかりません。あなたが与えることができるどんな助けにもみんなありがとう。
