两种方法
1.TextBox 绑定TextChanged 并设置AutoPostBack ="true" ，如果不设置AutoPostBack ="true"则不会触发TextChanged事件，然后在对应的方法里面循环Repeater查找改变项
部分代码
<ItemTemplate >
<tr>
<td style ="width :9%;"><%#Eval("Date")%> <asp:HiddenField ID ="hfkey" runat ="server" Value ='<%#Eval("ID")%> ' /></td>
<td style ="width :9%;"><%#Eval("FBASalesDays")%></td>
<td style ="width :9%;"><asp:TextBox ID ="txtUPSShipQty" runat="server" Text ='<%#Eval("UPSShipQty")%>' AutoPostBack ="true" OnTextChanged ="btnCal_Click" ></asp:TextBox> </td>
</tr>
</ItemTemplate>
后台部分代码
protected void btnCal_Click(object sender, EventArgs e)
{ foreach (RepeaterItem item in rpdList.Items)
{
if (item.ItemType == ListItemType.Item || item.ItemType == ListItemType.AlternatingItem)
{
HiddenField hfkey = item.FindControl("hfkey") as HiddenField; TextBox txtUPSShipQty = item.FindControl("txtUPSShipQty") as TextBox; DataRow[] rows = dt.Select("ID ='" + hfkey.Value + "'"); if (rows != null && rows.Length > )
{ if (rows[]["UPSShipQty"].ToString().Trim() != txtUPSShipQty.Text.Trim())
{
rows[]["UPSShipQty"] = txtUPSShipQty.Text.Trim(); CalFBAShipQty2(dt, , "UPSShipQty", hfkey.Value.Trim());
break;
} }
}
}
rpdList.DataSource = dt;
rpdList.DataBind();
}
2.让TextBox 触发Repeater 的ItemCommand事件，同样需要绑定TextChanged 并设置AutoPostBack ="true"，然后在TextChanged事件中调用ItemCommand
HTML
<asp:Repeater ID="Repeater1" runat="server"
onitemcommand="Repeater1_ItemCommand">
<ItemTemplate>
<%#Eval("txt") %><table>
<tr>
<td>
<asp:TextBox ID="TextBox1" runat="server" AutoPostBack="true" OnTextChanged="TextBox1_TextChanged"></asp:TextBox>
</td>
<td>
<asp:Button ID="Button1" runat="server" Text="Button" />
</td>
<td>
<asp:CheckBox ID="CheckBox1" runat="server" AutoPostBack="true"/>
</td>
</tr></table>
</ItemTemplate>
</asp:Repeater>
后台代码
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
DataTable dt = new DataTable();
dt.Columns.Add("id");
dt.Columns.Add("txt");
dt.Rows.Add("", "1txt");
dt.Rows.Add("", "2txt");
Repeater1.DataSource = dt;
Repeater1.DataBind();
}
}
protected void TextBox1_TextChanged(object sender, EventArgs e)
{
//注意这里的参数设置
RepeaterCommandEventArgs e1 = new RepeaterCommandEventArgs(((TextBox)sender).NamingContainer as RepeaterItem,sender,new CommandEventArgs("test",null));
Repeater1_ItemCommand(Repeater1, e1);
}
protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
{
string ss = e.CommandName;
if (ss == "test")
Response.Write("");
}
