我有一个转发器,它填充了3列的列表,每行旁边都有一个复选框。我正在尝试创建一个人检查行的方案,页面找到"部分名称"中继器行内的文本框与单击复选框的行对应,选中该复选框后,它将部分名称发送到转发器外的另一个文本框,名为" testTextBox.Text"。我在下面有我的代码,并且我确定我错过了一些东西,因为我没有做过" OnCheckChanged"之前的事件,我只熟悉onTextChanged事件。
以下是代码:
<asp:Repeater ID="rptAccount" runat="server" OnItemCommand="rptAccount_ItemCommand">
<HeaderTemplate>
<table>
<tr>
<th>Account
</th>
<th>Portion ID
</th>
<th>Portion Name
</th>
</tr>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td>
<asp:TextBox ID="Account" runat="server" Width ="50px" Text='<%#Eval("Account") %>' ></asp:TextBox>
</td>
<td>
<asp:TextBox ID="PortionID" runat="server" Width ="90px" Text='<%#Eval("Portion ID") %>' ></asp:TextBox>
</td>
<td>
<asp:TextBox ID="PortionName" runat="server" Width ="340px" Text='<%#Eval("Portion Name") %>'></asp:TextBox>
</td>
<td>
<asp:CheckBox ID="Name" runat="server" OnCheckedChanged = "TbName_CheckedChanged" Checked='<%# Eval("Name").ToString() == "True" %>' ></asp:CheckBox>
</td>
</tr>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>
cs code:
protected void TbName_CheckedChanged(object sender, EventArgs e)
{
var PortionName = (sender as TextBox).Parent;
var rptAccount = (sender as TextBox).Parent;
var checkedd = rptAccount.FindControl("Name") as CheckBox;
var PortionNamee = rptAccount.FindControl("PortionName") as TextBox;
if (checkedd.Checked)
{
testTextBox.Text = PortionNamee.Text;
}
}
感谢您提供的任何帮助。

转发器最终拥有大量名称为Name的控件。请记住,模板重复多次。你需要找到当前项目的索引。将属性附加到复选框以保存文本值的更简单方法是,您可以直接从发件人中提取它,而无需担心父级和索引。试试这个:
<asp:Repeater ID="rptAccount" runat="server" OnItemCommand="rptAccount_ItemCommand">
<HeaderTemplate>
<table>
<tr>
<th>Account
</th>
<th>Portion ID
</th>
<th>Portion Name
</th>
</tr>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td>
<asp:TextBox ID="Account" runat="server" Width ="50px" Text='<%#Eval("Account") %>' ></asp:TextBox>
</td>
<td>
<asp:TextBox ID="PortionID" runat="server" Width ="90px" Text='<%#Eval("Portion ID") %>' ></asp:TextBox>
</td>
<td>
<asp:TextBox ID="PortionName" runat="server" Width ="340px" Text='<%#Eval("Portion Name") %>'></asp:TextBox>
</td>
<td>
<asp:CheckBox ID="Name" runat="server" OnCheckedChanged = "TbName_CheckedChanged" CommandName='<%#Eval("Portion Name") %>' Checked='<%# Eval("Name").ToString() == "True" %>' ></asp:CheckBox>
</td>
</tr>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>
cs code:
protected void TbName_CheckedChanged(object sender, EventArgs e)
{
var checkedd = sender as Checkbox;
if (checkedd.Checked)
testTextBox.Text = checkedd.Attributes["CommandName"];
}
