问题是,文本为空。有数据,但不是值,而是空的…同样的代码在另一个页面上工作。所以,请告诉我。我做错了什么
如果您使用
模板字段
而不是边界字段
,单元格中的文本总是空的,谢谢。你要么必须
- 使用
模板字段中的控件
并使用行。FindControl(id)
查找它(我推荐)
- 或者您必须将第一个控件投射到有点奇怪的位置,因为您无法看到该控件。它会自动添加到单元格的控件集合中
GridViewRow row = gvClients.Rows[e.NewSelectedIndex];
txtClientNumber.Text = ((ITextControl)row.Cells[3].Controls[0]).Text;
谢谢您的建议…实际上,根据您的回答,结果如下:“\r\n Atomic Park.com”\r\n”…但我使用了修剪功能…结果如我所愿。再次感谢
GridViewRow row = gvClients.Rows[e.NewSelectedIndex];
txtClientNumber.Text = ((ITextControl)row.Cells[3].Controls[0]).Text;
