I have a DataGrid (.net framework 3.5, WPFToolKit). And i want to change borders (left or right) of some cells. One, two or three.So how can I get an access to a single cell? And is it possible?I've found some solutions, but they are for .net 4.
推荐答案
您可以扩展的DataGrid并添加以下,注意:这只是一个样本,你不需要做一些,我做了处理:
You can extend the DataGrid and add the following, NOTE: it's just a sample, you don't need to do some of the processing that I am doing:
public DataGridCell GetCell(int row, int column)
{
var rowContainer = GetRow(row);
if (rowContainer != null)
{
var presenter = FindVisualChild<DataGridCellsPresenter>(rowContainer);
if (presenter == null)
return null;
// try to get the cell but it may possibly be virtualized
var cell = (DataGridCell)presenter.ItemContainerGenerator.ContainerFromIndex(column);
if (cell == null)
{
// now try to bring into view and retreive the cell
ScrollIntoView(rowContainer, Columns[column]);
cell = (DataGridCell)presenter.ItemContainerGenerator.ContainerFromIndex(column);
}
return cell;
}
return null;
}
public DataGridRow GetRow(int index)
{
var row = (DataGridRow)ItemContainerGenerator.ContainerFromIndex(index);
if (row == null)
{
// may be virtualized, bring into view and try again
ScrollIntoView(Items[index]);
row = (DataGridRow)ItemContainerGenerator.ContainerFromIndex(index);
}
return row;
}
有关 FindVisualChild
的定义,看的。
