记录一下,主要是这句:
TextBox txtNum = e.Item.FindControl("txtNum") as TextBox;
Repeater真是太强了,太灵活。除了Repeater别的都不用。
复制代码代码如下:
<table>
<asp:Repeater ID="rptList" runat="server"OnItemCommand="rptList_ItemCommand">
<ItemTemplate>
<tr>
<td><asp:TextBox ID="txtNum" runat="server" Text='<%#Eval("ProNum")%>'></asp:TextBox></td>
<td><asp:Button ID="btnUpdate" runat="server" Text="更新"CommandName="update" CommandArgument='<%#Eval("PID") %>' /></td>
</tr>
</ItemTemplate>
</asp:Repeater>
</table>
复制代码代码如下:
protected void rptList_ItemCommand(object source, RepeaterCommandEventArgs e)
{
switch (e.CommandName)
{
case "update":
string arg = e.CommandArgument.ToString();//取得参数
//找到激发事件的行内控件,这个很有用,能将更多需要的参数值传递过来。
TextBox txtNum = e.Item.FindControl("txtNum") as TextBox;
//下面执行业务逻辑
string jsStr = "<script>alert('删除成功!" + txtNum.Text + "')</script>";
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "alert", jsStr,false);
break;
}
Bind();
}
