RadControls for Silverlight（学习1-RadGridView)

引用：Telerik（官 网：http://www.telerik.com/）是保加利亚的一个软件公司，专注于微软.Net平台的表示层与内容管理控件。我们提供高度稳定性和丰富性能的组件产品，并可应用在非常严格的环境中。现在拥有 Microsoft, HP, Alcoa, BP, Harper Collins, Siemens, T-Mobile, HJ Heinz和一些最主要的教育机构和很多政府机关等客户。

我在使用的版本是RadControls_for_Silverlight4_2011_1_0316，开发工具采用VS2010 +SQLServer2008R2进行测试学习

Grid是我们做系统必不可少的控件了，所以我准备从这个开始，为自己留下学习痕迹。

先是了解控件属性便于下一步学习，常用属性

RadGridView

常用属性	说明	DEMO名称
AutoGenerateColumns="False"	是否自动产生列
IsReadOnly="True" IsReadOnly="{Binding IsChecked, Mode=TwoWay, ElementName=IsReadOnlyCheckBox}"	是否只读	Click Event command
ShowGroupPanel="False"	是否显示分组面板（常用，一般情况下是不会用到这个的）
DataLoadMode="Asynchronous"	数据加载模式
RowIndicatorVisibility="Collapsed"	行指示
SelectionMode="Extended"		Command
CanUserDeleteRows="{Binding IsChecked, Mode=TwoWay, ElementName=CanUserDeleteRowsCheckBox}"	是否可删除行	Command
ScrollViewer.HorizontalScrollBarVisibility="Auto" ScrollViewer.VerticalScrollBarVisibility="Auto"	横向竖向滚动条设定
IsFilteringAllowed="False"	列过滤查询是否可用	Enable/Disable
ShowColumnFooters="True"	是否显示列脚	Totals
ShowGroupFooters="True"	是否显示分组列脚	Totals
GridLinesVisibility= Both Horizontal Vertical	网络线设置	gridlinevisiblity

GridViewDataColumn

属性	说明	DEMO名称
IsGroupable="False"	列是否加入分组
IsFilterable="False"	列是否可过滤查询
IsSortable="False"	列是否可排序
DataFormatString="{}{0:c2}" DataFormatString="{}{0:d}"	列输入格式

GridViewDataColumn.FilteringControl :可自定义表头查询控件

1、产生自动编号-Row Number

· 自定义列与绑定列并存

XAML
    <Grid>
        <telerik:RadGridView x:Name="RadGridView1" ItemsSource="{Binding Customers}" AutoGeneratingColumn="RadGridView1_AutoGeneratingColumn">
            <telerik:RadGridView.Columns>
                <custom:MyColumn Header="#" Width="50" />
            </telerik:RadGridView.Columns>
        </telerik:RadGridView>
    </Grid>

 
· 自动绑定后的列取消功能（如果取消的列较多，还是需要考虑用别的方法替代） 

 private void RadGridView1_AutoGeneratingColumn(object sender, Telerik.Windows.Controls.GridViewAutoGeneratingColumnEventArgs e)
        {
            if (e.Column.UniqueName == "Order" || e.Column.UniqueName == "Product") 
            {
                e.Cancel = true;
            }
        }
· 自定义列的处理
public class MyColumn : Telerik.Windows.Controls.GridViewColumn
    {
        public override FrameworkElement CreateCellElement(Telerik.Windows.Controls.GridView.GridViewCell cell, object dataItem)
        {
            TextBlock textBlock = cell.Content as TextBlock;
 
            if (textBlock == null)
            {
                textBlock = new TextBlock();
            }
 
            textBlock.Text = (this.DataControl.Items.IndexOf(dataItem) + 1).ToString();
 
            return textBlock;
        }
    }
 

2、行、列、单元格只读设置

private void ChangeEnableStateColumn(bool isEnabled)
   {
            GridViewHeaderRow headerRow = RadGridView1.ChildrenOfType<GridViewHeaderRow>().FirstOrDefault();
            if (headerRow != null)
            {
                GridViewCellBase cell = (from c in headerRow.Cells
                                        where c.Column.UniqueName == "EmployeeID"
                                             select c).FirstOrDefault();
                if (cell != null)
                {
                    cell.IsEnabled = isEnabled;
                }
            }
 
            foreach (object item in RadGridView1.Items)
            {
                GridViewRow row = RadGridView1.ItemContainerGenerator.ContainerFromItem(item) as GridViewRow;
                if (row != null)
                {
                    GridViewCellBase cell = (from c in row.Cells
                                             where c.Column.UniqueName == "EmployeeID"
                                             select c).FirstOrDefault();
                    if (cell != null)
                    {
                        cell.IsEnabled = isEnabled;
                    }
                }
            }
  }
 
private void ChangeEnableStateCell(bool isEnabled)
{
            if (RadGridView1.Items.Count > 0)
            {
                GridViewRow row = RadGridView1.ItemContainerGenerator.ContainerFromItem(RadGridView1.Items[0]) as GridViewRow;
                if (row != null)
                {
                    GridViewCellBase cell = (from c in row.Cells
                                             where c.Column.UniqueName == "EmployeeID"
                                             select c).FirstOrDefault();
                    if (cell != null)
                    {
                        cell.IsEnabled = isEnabled;
                    }
                }
            }
}
 
private void ChangeEnableStateRow(bool isEnabled)
        {
            if (RadGridView1.Items.Count > 0)
            {
                GridViewRow row = RadGridView1.ItemContainerGenerator.ContainerFromItem(RadGridView1.Items[0]) as GridViewRow;
                if (row != null)
                {
                    row.IsEnabled = isEnabled;
                }
            }
}

XAML
    <Grid>
        <telerik:RadGridView x:Name="RadGridView1" ItemsSource="{Binding Customers}" AutoGeneratingColumn="RadGridView1_AutoGeneratingColumn">
            <telerik:RadGridView.Columns>
                <custom:MyColumn Header="#" Width="50" />
            </telerik:RadGridView.Columns>
        </telerik:RadGridView>
    </Grid>

3、设置网格线颜色

private void VerticalGridLinesColorPicker_SelectedColorChanged(object sender, EventArgs e)
{
RadGridView1.VerticalGridLinesBrush = new SolidColorBrush(VerticalGridLinesColorPicker.SelectedColor);
}
 
private void HorizontalGridLinesColorPicker_SelectedColorChanged(object sender, EventArgs e)
{
RadGridView1.HorizontalGridLinesBrush = new SolidColorBrush(HorizontalGridLinesColorPicker.SelectedColor);
}      

4、保存用户对网格的设置

DEMO中saveandload settings中的Radgridviewsetting.cs非常用用：)
