如何测试gridview的一行是否为空asp.net
我在页面加载时有一个空的网格视图。 在RowDataBound事件中,我向最后一个单元格添加了dropdownlist 问题是ddl在页面加载时显示。 如果行的单元格为空,我想将其隐藏如何测试gridview的一行是否为空asp.net,asp.net,gridview,webforms,dropdown,rowdatabound,Asp.net,Gridview,Webforms,Dropdown,Rowdatabound,我在页面加载时有一个空的网格视图。 在RowDataBound事件中,我向最后一个单元格添加了dropdownlist 问题是ddl在页面加载时显示。 如果行的单元格为空,我想将其隐藏 protected void grw_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { D

谢谢。请尝试以下代码:
if (e.Row.RowType == DataControlRowType.DataRow)
{
// Check if the first two cells of row are not empty
if (e.Row.Cells[0].Text != "" || e.Row.Cells[1].Text != "")
{
DropDownList ddl = e.Row.FindControl("ddlAccepted") as DropDownList;
if (null != ddl)
{
string acceptedKey = (e.Row.FindControl("lblAccepted") as Label).Text;
string acceptedValue = "";
if (acceptedKey == "True")
{
acceptedValue = "Oui";
}
else if (acceptedKey == "False")
{
acceptedValue = "Non";
}
ddl.Items.Add(new ListItem("Non", "False"));
ddl.Items.Add(new ListItem("Oui", "True"));
ddl.SelectedValue = acceptedValue;
}
}
}
只需在代码中添加此(如果
检查):
// Check if the first two cells of row are not empty
if (e.Row.Cells[0].Text != "" || e.Row.Cells[1].Text != "")
{
//... do some other code here
}
我找到了解决办法
空单元格的文本等于
所以我加上这一行,它就行了
if (e.Row.Cells[0].Text != " ")
您是如何填充gridview的?
string requete=“选择”“作为id”“作为案例编号”“作为干预者”“作为请求者”“作为发送日期”“作为收件人”“作为接收日期”“作为状态代码”“作为IsAccepted”;grw.DataSource=GetEmptyDataSet(重新查询);grw.DataBind()
GetEmptyDataSet返回没有行或有空行的数据集?public静态数据表GetEmptyDataSet(字符串查询){DataTable DataTable=null;SqlConnection=null;try{connection=Open();SqlCommand=new SqlCommand(查询,连接);SqlDataAdapter adapter=new SqlDataAdapter(命令);dataTable=new dataTable();adapter.Fill(dataTable);}最后{Close(连接);}返回dataTable;}
