datagrid 控件，如何点击一次某单元格，即可获取该单元格的内容

前台代码：

<Grid >

<GridRowDefinitions>

<RowDefinition/>

<RowDefinition Height="25"/>

</GridRowDefinitions>

<DataGrid Name="dg" AutoGenerateColumns="True" RowHeaderWidth="0" SelectedCellsChanged="dg_SelectedCellsChanged" SelectionUnit="Cell"></DataGrid>

<TextBlock GridRow="1" Name="txt"/>

</Grid>

后台代码：

public partial class BaiduKnows : Window

{

public BaiduKnows()

{

InitializeComponent();

List<People> peoplelist = new List<People>();

peoplelistAdd(new People() { age = 10, name = "linda" });

peoplelistAdd(new People() { age = 11, name = "tom" });

peoplelistAdd(new People() { age = 12, name = "peter" });

peoplelistAdd(new People() { age = 13, name = "mary" });

dgItemsSource = peoplelist;

}

class People

{

public int age { get; set; }

public string name { get; set; }

}

private void dg_SelectedCellsChanged(object sender, SelectedCellsChangedEventArgs e)

{

DataGrid dg = sender as DataGrid;

People item = dgSelectedCells[0]Item as People;

string colhead = dgSelectedCells[0]ColumnHeaderToString();

switch (colhead)

{

case "age" : txtText = itemageToString();

break;

case "name": txtText = itemnameToString();

break;

}

}

}

DataGridViewCell cell = null;

if (dataGridView1SelectedCellsCount > 0)

{

cell = dataGridView1[dataGridView1SelectedCells[0]ColumnIndex, dataGridView1SelectedCells[0]RowIndex];

MessageBoxShow(cellValue == null "" : cellValueToString());

}

CellClick 事件

private void dataGridView1_Click(object sender, EventArgs e)

{

int row =dataGridView1CurrentRowIndex;

TextBox1Text=dateGridView1[0,row]ValueToString();

TextBox2Text=dateGridView1[0,row]ValueToString();

}

Button b = ecell[i]findcontrol("Id") as Button;

bText="abc";

大致是这个意思即：我们通过ecell[i]这个指定列来查找控件ID为Id的控件(即你放入的button），然后将之转换为Button即可，这个Button即为你要获取的按钮，下面的bText="abc"，就是你要设置他的text属性
