问题描述
这是我的代码页
this is my code page
public partial class BindingCheckboxlist : System.Web.UI.Page
{
bis_ obj = new bis_();
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
DataSet ds = new DataSet();
ds = obj.get_Title();
if (ds.Tables[0].Rows.Count > 0)
{
chklist.DataSource = ds.Tables[0];
chklist.DataTextField = "Title";
chklist.DataValueField = "Id";
chklist.DataBind();
}
}
}
protected void btnSubmit_Click(object sender, EventArgs e)
{
string Id = "";
int var = 0;
for (int i = 0; i < chklist.Items.Count; i++)
{
if (chklist.Items[i].Selected)
{
if (var == 0)
{
Id += chklist.Items[i].Value;
var = var + 1;
}
else
Id += "," + chklist.Items[i].Value;
}
lblId.Text = "You Are selected:" + Id;
}
string Name = "";
for (int i = 0; i < chklist.Items.Count; i++)
{
if (chklist.Items[i].Selected)
{
Name += chklist.Items[i].Text + ",";
}
lblName.Text = "Your Selected citys are:" + Name;
}
//string Id1 = "";
//chklist2.DataSource = chklist.SelectedValue;
//chklist.DataTextField = chklist.selel;
//chklist2.DataValueField = chklist.SelectedValue;
//chklist2.DataBind();
for(int i=0;i<chklist.items.count;i++)>
{
if (chklist.Items[i].Selected)
{
}
}
}
}
这是设计页面：
This is designing page:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="BindingCheckboxlist.aspx.cs" Inherits="BindingCheckboxlist" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<table align="center">
<tr><td>
<asp:CheckBoxList runat="server" ID="chklist"><br />
</td>
</tr>
<tr>
<td>
<asp:Button runat="server" ID="btnSubmit" Text="Submit" onclick="btnSubmit_Click" />
<br />
</td>
</tr>
<tr>
<td>
<asp:Label runat="server" ID="lblId"><br />
<asp:Label runat="server" ID="lblName">
</td>
</tr>
<tr>
</tr>
<td>
<asp:CheckBoxList runat="server" ID="chklist2">
</td>
</table>
</div>
</form>
</body>
</html>
这里我的要求是如果我从第一个复选框列表值中选择然后将那些相同的值绑定到第二个复选框;
here my requirement is if i selectd from first check box list values then bind those same values to second checkbox;
推荐答案
你好，
请试试这个，
Hello,
Please try this,
<asp:checkboxlist runat="server" id="chklist" xmlns:asp="#unknown">
</asp:checkboxlist>
<asp:button runat="server" id="btnSubmit" text="Submit" xmlns:asp="#unknown">
onclick="btnSubmit_Click" />
<asp:label runat="server" id="lblId"></asp:label>
<asp:label runat="server" id="lblName"></asp:label>
<div runat="server" id="NewCheckBox"></div></asp:button>
SqlConnection cn = new SqlConnection(@"");
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
string query = @"SELECT * FROM Products";
SqlDataAdapter ad = new SqlDataAdapter(query, cn);
DataSet ds = new DataSet();
ad.Fill(ds);
if (ds.Tables[0].Rows.Count > 0)
{
chklist.DataSource = ds.Tables[0];
chklist.DataTextField = "ProductName";
chklist.DataValueField = "Id";
chklist.DataBind();
}
}
}
protected void btnSubmit_Click(object sender, EventArgs e)
{
string Id = "";
int var = 0;
for (int i = 0; i < chklist.Items.Count; i++)
{
if (chklist.Items[i].Selected)
{
if (var == 0)
{
Id += chklist.Items[i].Value;
var = var + 1;
}
else
Id += "," + chklist.Items[i].Value;
}
lblId.Text = "You Are selected:" + Id;
}
string Name = "";
for (int i = 0; i < chklist.Items.Count; i++)
{
if (chklist.Items[i].Selected)
{
Name += chklist.Items[i].Text + ",";
}
lblName.Text = "Your Selected citys are:" + Name;
}
List<int> _intid = Id.TrimEnd(',').Split(',').ToList().ConvertAll<int>(s => Convert.ToInt32(s));
if (_intid.Count() > 0)
{
foreach (var item in _intid)
{
string query = @"SELECT * FROM Category where PId=" + item;
SqlDataAdapter ad = new SqlDataAdapter(query, cn);
DataSet ds = new DataSet();
ad.Fill(ds);
CheckBoxList chklst2 = new CheckBoxList();
chklst2.DataSource = ds.Tables[0];
chklst2.DataTextField = "CategoryName";
chklst2.DataValueField = "PId";
chklst2.DataBind();
NewCheckBox.Controls.Add(chklst2);
}
}
}
</int></int>
