C# radgrid的问题

我在RadGrid方面遇到了一些问题。一个是我在RadGrid中有GridClientSelectColumn。我可以使用标题复选框选择所有复选框，但无法选择单个复选框。另一种情况是，当我单击某行时，我正在更改该行的背景色，但它没有完全显示出来。只有一半的行正在更改颜色（请参见图1）。另一个是我在CommandItem模板中有RadMenu。显示不正确（参见图2）。这是我的代码

将尽量简短：

如何有条件地设置telerik网格行的样式-

复选框select列应该同时适用于select all和select single-检查站点上的javascript错误是否阻止了这一点

我看到根菜单项的CssClass属性为空-这会破坏其渲染吗？还要检查为内部项设置的图像URL是否有效

protected void gvPjtMnt_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        GridDataItem dataItem = e.Item as GridDataItem;
        TableCell myCell = dataItem["ProjectHealth"];
        myCell.Font.Size = 10;
        myCell.Font.Bold = true;

        if (myCell.Text.Trim() == "GREEN")
        {
            myCell.BackColor = System.Drawing.Color.Green;
            myCell.ForeColor = System.Drawing.Color.White;
        }
        if (myCell.Text.Trim() == "RED")
        {
            myCell.BackColor = System.Drawing.Color.Red;
            myCell.ForeColor = System.Drawing.Color.White;
        }
        if (myCell.Text.Trim() == "YELLOW")
        {
            myCell.BackColor = System.Drawing.Color.Yellow;
            myCell.ForeColor = System.Drawing.Color.Black;
        }
        if (myCell.Text.Trim() == "COMPLETE")
        {
            myCell.BackColor = System.Drawing.Color.Blue;
            myCell.ForeColor = System.Drawing.Color.White;
        }
    }

}
