【WPF】遍历DataGrid

网上找了遍历DataGrid,但是都不能用，终于组合出来了~~

///<summary>

/// 获取DataGrid遍历后的数据

///</summary>

///<param name="dg"></param>

///<returns></returns>

publicstring DataGrid(DataGrid dg)

{

try

{

string str = "";

for (int j = 0; j < dg.Items.Count; j++)

{

DataGridCell c = DataGridHelper.GetCell(dg, j, 0);

TextBlock tb = c.Content asTextBlock;

if (str.Equals(string.Empty))

{

str = tb.Text;

}

else

{

str = str +"!" + tb.Text;//直接获取datagrid 遍历后的当前数据

}

}

 return str;

}

catch

{

 returnnull;

}

}

Class :

以下代码网上扒的~~~~

staticclassDataGridHelper

{

staticpublicDataGridCell GetCell(DataGrid dg, int row, int column)

{

DataGridRow rowContainer = GR(dg, row);

if (rowContainer != null)

{

DataGridCellsPresenter p = GC<DataGridCellsPresenter>(rowContainer);

DataGridCell cell = (DataGridCell)p.ItemContainerGenerator.ContainerFromIndex(column);

if (cell == null)

{

dg.ScrollIntoView(rowContainer, dg.Columns[column]);

cell = (DataGridCell)p.ItemContainerGenerator.ContainerFromIndex(column);

}

return cell;

}

else

{

returnnull;

}

}

　

　

staticpublicDataGridRow GR(DataGrid dg, int index)

{

DataGridRow r = (DataGridRow)dg.ItemContainerGenerator.ContainerFromIndex(index);

if (r == null)

{

dg.ScrollIntoView(dg.Items[index]);

r = (DataGridRow)dg.ItemContainerGenerator.ContainerFromIndex(index);

}

return r;

}

　

　

static T GC<T>(Visual parent) where T : Visual

{

T child =default(T);

int numVisuals = VisualTreeHelper.GetChildrenCount(parent);

for (int i = 0; i < numVisuals; i++)

{

Visual v = (Visual)VisualTreeHelper.GetChild(parent, i);

child = vas T;

if (child == null)

{

child = GC<T>(v);

}

if (child != null)

{

break;

}

}

return child;

}
