Question

asp.net中怎么循环repeater控件取出每行数据

Answer 1

DEMO.aspx

asp:Repeater ID="Repeater1" runat="server">
<ItemTemplate>
<asp:Label ID="lbl_ID" runat="Server" Text='<%#Eval("ID") %>'></asp:Label>
<asp:Label ID="lbl_NAME" runat="Server" Text='<%#Eval("NAME") %>'></asp:Label>
</ItemTemplate>
</asp:Repeater>

<asp:Button ID="btn_Get" runat="Server" OnClick="btn_Get_Click" Text="遍历" />

DEMO.aspx.cs

protected void Page_Load(object sender, EventArgs e)
{
DataTable dt = new DataTable();
dt.Columns.Add("ID");
dt.Columns.Add("NAME");

for (int i = 0; i <= 10; i++ )
{
DataRow dr = dt.NewRow();
dr["ID"] = i;
dr["NAME"] = "NAME" + i.ToString();
dt.Rows.Add(dr);
}

this.Repeater1.DataSource = dt;
this.Repeater1.DataBind();
}

protected void btn_Get_Click(object sender, EventArgs e)
{
foreach (RepeaterItem rs in Repeater1.Items)
{
string str_ID = ((Label)rs.FindControl("lbl_ID")).Text;
string str_Name = ((Label)rs.FindControl("lbl_Name")).Text;
string str_Message = "ID:" + str_ID + " Name:" + str_Name;
Response.Write("<script>alert('" + str_Message + "')</script>");
}
}

为了演示，我直接用DataTable作为数据源，遍历的方式就是这样，如果你的页面有嵌套母版页的话要注意FindControl()里的控件名称不是控件的ID，而是控件.ClientID。
