试试这个，

使用foreach循环：

 foreach (GridViewRow row in GridView1.Rows) { CheckBox chk = row.Cells[0].Controls[0] as CheckBox; if (chk != null && chk.Checked) { // ... } } 

在OnRowCommand事件中使用它并获取CheckBox值。

 GridViewRow row = (GridViewRow)(((Control)e.CommandSource).NamingContainer); int requisitionId = Convert.ToInt32(e.CommandArgument); CheckBox cbox = (CheckBox)row.Cells[3].Controls[0]; 

对于运行GridView的所有行都不使用for循环，使用foreach循环如：

 foreach (GridViewRow row in yourGridName.Rows) //Running all lines of grid { if (row.RowType == DataControlRowType.DataRow) { CheckBox chkRow = (row.Cells[0].FindControl("chkRow") as CheckBox); if (chkRow.Checked) { //if checked do something } } } 

如果你想要一个findcontrol以外的方法，请尝试以下方法：

  GridViewRow row = Gridview1.SelectedRow; int CustomerId = int.parse(row.Cells[0].Text);// to get the column value CheckBox checkbox1= row.Cells[0].Controls[0] as CheckBox; // you can access the controls like this 

  foreach (DataRow row in DataRow row in GridView1.Rows) { foreach (DataColumn c in GridView1.Columns) bool ckbVal = (bool)(row[c.ColumnName]); } 

大段引用

  foreach (GridViewRow row in tempGrid.Rows) { dt.Rows.Add(); for (int i = 0; i < row.Controls.Count; i++) { Control control = row.Controls[i]; if (control.Controls.Count==1) { CheckBox chk = row.Cells[i].Controls[0] as CheckBox; if (chk != null && chk.Checked) { dt.Rows[dt.Rows.Count - 1][i] = "True"; } else dt.Rows[dt.Rows.Count - 1][i] = "False"; } else dt.Rows[dt.Rows.Count - 1][i] = row.Cells[i].Text.Replace(" ", ""); } } 

您希望网格视图中的所有行都有一个独立的for循环，然后参考下面的链接

  foreach (GridViewRow row in GridView1.Rows) { CheckBox chkbox = (CheckBox)row.FindControl("CheckBox1"); if (chkbox.Checked == true) { // Your Code } }
