c# - 我需要更改 asp :buttons that are in a ListView from code behind

Question

我在 ListView 中有一些按钮，我需要通过代码隐藏更改它们的 CSS 属性，以便可以通过函数动态更改颜色。

我收到以下错误:

**Error 6 The name 'SubDomainButton' does not exist in the current context.**

我很高兴能够编辑当前分配给按钮的 CSS 类或引用 ListView 内的按钮。

我想做类似...

SubDomainButton.Style.Add("border-color", (string)    (Session["BorderFontColor"]));
SubDomainButton.Style.Add("color", (string)(Session["BorderFontColor"]));
SubDomainButton.Style.Add("background-color", (string)(Session["BackgroundColor"]));

HTML 段:

<asp:ListView ID="SubDomainListView" runat="server" DataKeyNames="ID" DataSourceID="SubDomainSqlDataSource"
                    EnableModelValidation="True" OnItemCommand="SubDomainListView_ItemCommand">

                    <itemtemplate>
                        <asp:Button ID="SubDomainButton" runat="server" Text='<%# Eval("SubDomain") %>' CommandText="click" CommandName="Select"
                            CommandArgument='<%# Eval("ID")%>' UseSubmitBehavior="False" CssClass="button" />
                </itemtemplate>
                    <selecteditemtemplate>
                        <asp:Button ID="Button2" runat="server" Text='<%# Eval("SubDomain") %>' CommandText="click" CommandName="Select"
                            CommandArgument='<%# Eval("ID")%>' UseSubmitBehavior="False" CssClass="buttoninact" Enabled="False"   />
    </selecteditemtemplate>
                    <layouttemplate>
                    <div id="itemPlaceholder" runat="server">
                    </div>
                </layouttemplate>
                </asp:ListView>

CSS: /* 按钮样式 */

.button {
-webkit-box-shadow: rgba(0,0,0,0.0.1) 0 1px 0 0;
-moz-box-shadow: rgba(0,0,0,0.0.1) 0 1px 0 0;

}

您可以通过添加内联 CSS 样式来实现:

<itemtemplate>
    <asp:Button ID="SubDomainButton" runat="server" Text='<%# Eval("SubDomain") %>' CommandText="click" CommandName="Select" CommandArgument='<%# Eval("ID")%>' UseSubmitBehavior="False" CssClass="button"
style='<%# String.Format("border-color: {0}; color: {1}; background-color: {2};",(string)Session["BorderFontColor"],(string)Session["BorderFontColor"],(string)Session["BorderFontColor"]) %>' />
</itemtemplate>
