我有一个Gridview，其中包含一些从数据库中添加的数据。所以我想要的是，如果金额列中的值为0或NULL
我尝试了RowDataBound，如下所示
if (e.Row.Cells[10].Text == "0")
{
e.Row.Cells[15].Style["display"] = "none";
}
但它确实列是""
那么如果值为0

使用模板列并检查脚本中的条件。根据您的条件显示该列中的数据。请参阅https://msdn.microsoft.com/en-us/library/bb288032.aspx

是的，可以通过在gridview的模板字段中使用服务器控件来实现
的.aspx
<style>
.btnHidden {
display: none !important;
}
</style>
和.cs
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.Cells[0].Text == "10537")
{
Button btnHidden = e.Row.FindControl("btnHidden") as Button;
if (btnHidden != null)
{
btnHidden.CssClass = "btnHidden";
}
}
}

这个ans可以帮助你。

和.cs
using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data;
using System.Data.SqlClient;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace StackOverflow_Solve.Others
{
public partial class GridView : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
grdvShowUsers.DataSource = GetData();
grdvShowUsers.DataBind();
}
}
private DataTable GetData()
{
DataTable dt=new DataTable();
String connectionString = ConfigurationManager.ConnectionStrings["WaltonCrmConnectionString"].ConnectionString; ;
using (var conn = new SqlConnection(connectionString))
{
conn.Open();
string servicePointListQuery = String.Format(@"select UserID,UserName from Users ");
var command = new SqlCommand(servicePointListQuery, conn);
SqlDataAdapter dataAdapter=new SqlDataAdapter(command);
dataAdapter.Fill(dt);
}
return dt;
}
protected void grdvShowUsers_RowDataBound(object sender, GridViewRowEventArgs e)

if (e.Row.RowType == DataControlRowType.DataRow)

{
Button btnHidden = e.Row.FindControl("btnHidden") as Button;
if (btnHidden != null)
{
btnHidden.CssClass = "btnHidden";
}
}
}
}
}
}
和javascript解决方案并且不要忘记在网格视图中添加ClientIDMode="Static"
$("#grdvShowUsers tr").each(function (index) {
//Excluding Header
if (index != 0) {
var userid = $(this).find('td:eq(0)').text();
// if (userid === '11614') {
$(this).find('input[type="submit"]').addClass("btnHidden");
//}
}
});
