wpf datagrid 遍历行
如果 DataGrid 中的行还未被加载,即 LoadingRow 事件未发生,那么针对此行的 GetCellContent() 是不可能得到东西的,只能为 null。
下面两种语法,只是变相的形式而已。
for (int i = 0; i < dgETL.Items.Count; i++)
{
CheckBox selectCheckBoxInCell = dgETL.Columns[0].GetCellContent(dgETL.Items[i]) as CheckBox;
if (selectCheckBoxInCell != null)
{
selectCheckBoxInCell.IsChecked = cbxOne.IsChecked;
}
}
foreach (var item in dgETL.Items)
{
CheckBox selectCheckBoxInCell = dgETL.Columns[0].GetCellContent(item) as CheckBox;
if (selectCheckBoxInCell != null)
{
selectCheckBoxInCell.IsChecked = cbxOne.IsChecked;
}
}
GridViewRow s = ((GridViewRow)PSFileDataGrid.ItemContainerGenerator.ContainerFromIndex(1));
if (s != null)
{
Button sb = null;
GridViewCellBase j =
(from c in s.Cells where c.Column.Name == "uid" select c).FirstOrDefault();
if (j != null)
{
sb = j.Template.FindName("button1", j) as Button;
sb.IsEnabled = false;
}
}
