我正在尝试从文本框中插入值,但是我收到一个错误,它无法在controlparameter中找到controlid。 TextBox位于表单视图中,该表单视图位于列表视图中。 SqlDataSource在ListView之外。
我的InsertButton_Click方法
protected void InsertButton_Click(object sender, EventArgs e)
{
var ctrl = (Control)sender;
var formview = (FormView)ctrl.NamingContainer;
formview.ChangeMode(FormViewMode.Insert);
SectionListView.DataSource = SectionDataSource;
SectionListView.DataBind();
}
InsertItem模板
<InsertItemTemplate>
<tr style="">
<td>
<div style="font-size: .8em;">
<asp:FormView ID="SectionFormView" runat="server" DataKeyNames="SectionItemID" DataSourceID="SectionDataSource">
<ItemTemplate>
<asp:Button ID="InsertButton" runat="server" CommandName="Insert" Text="Insert" OnClick="InsertButton_Click" Font-Size="1.2em" />
<asp:Button ID="CancelButton" runat="server" CommandName="Cancel" Text="Clear" Font-Size="1.2em" />
<asp:Label ID="SectionItemLabel" runat="server" Text="SectionItem" Font-Bold="true" Font-Size="1.2em" />
<asp:TextBox ID="SectionItemTextBox" runat="server" />
<asp:Label ID="SectionItemSubLabel" runat="server" Text="SectionItem Label" Font-Bold="true" Font-Size="1.2em" />
<asp:TextBox ID="SectionItemLabelTextBox" runat="server"/>
</ItemTemplate>
</asp:FormView>
</div>
</td>
</tr>
</InsertItemTemplate>
我的SqlDataSource
<asp:SqlDataSource ID="SectionDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:ORHP_Dev03182014ConnectionString %>" SelectCommand="SELECT DISTINCT SectionItem,SectionItemLabel,SectionItemID FROM Core.SectionItem_Lkup"
InsertCommand="INSERT INTO Core.SectionItem_Lkup(SectionItem, SectionItemLabel) VALUES (@SectionItem, @SectionItemLabel)">
<InsertParameters>
<asp:ControlParameter ControlID="SectionItemTextBox" Name="SectionItem" PropertyName="Text" />
<asp:ControlParameter ControlID="SectionItemLabelTextBox" Name="SectionItemLabel" PropertyName="Text" />
</InsertParameters>
</asp:SqlDataSource>
答案 0 :(得分:4)
如果要将子控件用作控件参数,则需要使用限定ID作为控件ID。尝试更改SQL数据源,如下所示
<asp:SqlDataSource ID="SectionDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:ORHP_Dev03182014ConnectionString %>" SelectCommand="SELECT DISTINCT SectionItem,SectionItemLabel,SectionItemID FROM Core.SectionItem_Lkup"
InsertCommand="INSERT INTO Core.SectionItem_Lkup(SectionItem, SectionItemLabel) VALUES (@SectionItem, @SectionItemLabel)">
<InsertParameters>
<asp:ControlParameter ControlID="SectionFormView$SectionItemTextBox" Name="SectionItem" PropertyName="Text" />
<asp:ControlParameter ControlID="SectionFormView$SectionItemLabelTextBox" Name="SectionItemLabel" PropertyName="Text" />
</InsertParameters>
</asp:SqlDataSource>
