我有一个包含多个表单字段的预览页面。以下是其中几个:
<asp:Repeater ID="rptpreview" runat="server">
<ItemTemplate>
<table style="width: 100%; border: 1px solid black;">
<tr>
<td style="width: 33.3%; border-collapse: collapse; white-space: nowrap;">
Airport where aircraft primary home based city:
<asp:Label ID="lblAircraftCity" Text='<%#Eval("aircity") %>'
Style="width: 270px; color: #0093B2; font-weight: bold;"
runat="server"></asp:Label>
</td>
</tr>
</Table>
</ItemTemplate>
</asp:Repeater>
我想要做的是将值传递给代码隐藏文件中的这些表单字段,以便用户在提交之前能够查看其条目。以下是代码隐藏文件中的一小部分数据:
int rowIndex = 0;
if (ViewState["CurrentTable"] != null)
{
//Initialize datatable.
DataTable ctable = ViewState["CurrentTable"] as DataTable;
DataTable preview = ctable.Clone();
int rowNumber = 1;
//Lets start looping through the second datatable for aircraft schedule info. .
if (ctable.Rows.Count > 0)
{
for (int i = 1; i <= Repeater2.Items.Count; i++)
{
DataRow dr = preview.NewRow();
lblAircraftCity.Text =
((TextBox)Repeater2.Items[rowIndex].FindControl("aircraftCity")).Text;
lblAircraftcnty.Text =
((TextBox)Repeater2.Items[rowIndex].FindControl("aircraftcnty")).Text;
preview.Rows.Add(dr);
rowNumber++;
rowIndex++;
}
rptpreview.DataSource = preview;
rptpreview.DataBind();
}
}
此代码抛出的错误表明某些字段无法识别。有人可以帮忙吗?
答案 0 :(得分:0)
您在Repeater中有一个Label并将其转换为TextBox,这会引发无法识别的字段错误。把它投到Label:
DataRow dr = preview.NewRow();
dr["aircity"] = ((Label)Repeater2.Items[rowIndex].FindControl("aircraftCity")).Text;
dr["aircnty"] = ((Label)Repeater2.Items[rowIndex].FindControl("aircraftcnty")).Text;
这将解决您的问题,lblAircraftCity.Text
且lblAircraftCnty.Text
无法访问Repeater外部,因此您必须分别使用dr["aircity"]
和dr["aircnty"]
。
