WPF中怎么获取dataGrid内的所有数据

试试这个，不然的话只能循环读取了

public DataTable GetDgToTable(DataGrid dgv)

{

DataTable dt = new DataTable()

for (int count = 0count <dgv.Columns.Countcount++)

{

DataColumn dc = new DataColumn(dgv.Columns[count].Name.ToString())

dt.Columns.Add(dc)

}

for (int count = 0count <dgv.Rows.Countcount++)

{

DataRow dr = dt.NewRow()

for (int countsub = 0countsub <dgv.Columns.Countcountsub++)

{

dr[countsub] = Convert.ToString(dgv.Rows[count].Cells[countsub].Value)

}

dt.Rows.Add(dr)

}

return dt

}

如果你设定AutoGenerateColumns就不会自动生成列，需要手动指定datagrid的列。

例如:

<DataGrid AutoGenerateColumns="False" Height="418" HorizontalAlignment="Left" Name="dataGrid1" VerticalAlignment="Top" Width="316" >

<DataGrid.Columns>

<DataGridTextColumn Header="列名" Binding="{Binding Path=你的ds.Tables[0]的某一列的列名, Mode=TwoWay}" Width="380"/>

</DataGrid.Columns>

</DataGrid>
