从数据绑定Gridview获取复选框

发布于 2024-12-15 04:31:41 字数 578 浏览 2 评论 0原文

有没有办法检索 ASP.NET 中的数据绑定网格视图中是否选中了复选框字段？我可以使用 cell.Text 在 foreach 循环中检索所有其他单元格值。由于它是数据绑定的（到 ObjectDataSource），列和单元格没有显式设置的 ID，而且我似乎找不到可以让我知道单元格包含复选框或仅包含文本的属性。所有单元格的类型均为 DataControlFieldCell，因此我也无法根据类型进行检查。想法？

编辑：

foreach (GridViewRow row in report_gv.Rows)
{
   data += "<TR>";
   foreach (TableCell cell in row.Cells)
   {
      data += "<TD>" + cell.Text + "</TD>";
      //If this is a checkbox (bit value from the DB) cell.Text isn't going to return anything
   }
   data += "</TR>";
}

Is there a way to retrieve whether a Checkbox field is checked in a databound gridview in ASP.NET? I can retrieve all other cell values in a foreach loop with cell.Text. Since it is databound (to an ObjectDataSource) the columns and cells don't have explicitly set IDs and I can't seem to find a property that would let me know the cell contains a checkbox or just text. All cells are of type DataControlFieldCell so I can't check based on type either. Thoughts?

EDIT:

foreach (GridViewRow row in report_gv.Rows)
{
   data += "<TR>";
   foreach (TableCell cell in row.Cells)
   {
      data += "<TD>" + cell.Text + "</TD>";
      //If this is a checkbox (bit value from the DB) cell.Text isn't going to return anything
   }
   data += "</TR>";
}

foreach (GridViewRow row in myGridView) {
  foreach (TableCell cell in row.Cells) {
    foreach (Control ctrl in cell.Controls) {
      if (ctrl is CheckBox) {
        CheckBox cb = (CheckBox)ctrl;
        // use cb
      } else if (cell is TextBox) {
      } else if (cell is Label) {
      }
    }
  }
}

您可以根据需要扩展此处理。

foreach (GridViewRow row in myGridView) {
  foreach (TableCell cell in row.Cells) {
    foreach (Control ctrl in cell.Controls) {
      if (ctrl is CheckBox) {
        CheckBox cb = (CheckBox)ctrl;
        // use cb
      } else if (cell is TextBox) {
      } else if (cell is Label) {
      }
    }
  }
}

You can expand this to process however you need.

您可以在 GridViewItem 上使用 FindControl 并按 ItemTemplate 定义中的复选框 ID 进行搜索。

FindControl GridView 上有很多示例，

例如查看以下内容：gridView 中的复选框

你可以做到的。但更简单的方法是转换为，这将允许您为 CheckBox 分配一个 ID。然后你的 foreach 就变成了：

foreach (GridViewRow row in myGridView) {
  CheckBox myCB = (CheckBox)row.FindControl("gvIdentifier");

  // Do something with myCB
}

You can do it. But easier is to convert to a <TemplateField>, which will allow you to assign an ID to your CheckBox. Then your foreach goes:

foreach (GridViewRow row in myGridView) {
  CheckBox myCB = (CheckBox)row.FindControl("gvIdentifier");

  // Do something with myCB
}

在 GridView.RowDataBound 事件您可以访问每行内的每个复选框。
尝试这样的事情

<ItemTemplate>
<asp:CheckBoxList ID="chb1" runat="server">
</ItemTemplate>

protected void GvRowDataBound(object sender, GridViewRowEventArgs e)
{
            var chb = (CheckBox) e.Row.FindControl("chb1");
            var ischeck = false;
            if(chb != null)
            {
                if(chb.Checked)
                {
                    ischeck = true;
                }
            }
}

In GridView.RowDataBound Event you can access each and every checkbox that inside each row.
Try something like this

<ItemTemplate>
<asp:CheckBoxList ID="chb1" runat="server">
</ItemTemplate>

protected void GvRowDataBound(object sender, GridViewRowEventArgs e)
{
            var chb = (CheckBox) e.Row.FindControl("chb1");
            var ischeck = false;
            if(chb != null)
            {
                if(chb.Checked)
                {
                    ischeck = true;
                }
            }
}
