Question

我的准备功能有问题。我正在尝试选择Delete button以便能够禁用/启用它。这是选择第一个项目的代码（可以是下拉组）。我正在尝试选择该组中的第一个项目。

var prepareRecruiter = function (grid, toolbar, rowIndex, record) {
var dropdown = toolbar.items.get(0);
dropdown.setDisabled(true);
};

我尝试了toolbar.items.get(0).get(0);和toolbar.items.items.get(0);的多个变体而没有成功。

如何选择删除按钮，以便我可以将其禁用？

我的网格命令有以下代码：

<ext:CommandColumn runat="server" Width="35" Sortable="false" fixed="true" meta:resourcekey="CommandColumnResource2" ID="ctl2108">
    <Commands>
        <ext:GridCommand Icon="ApplicationForm">
            <Menu EnableScrolling="false">
                <Items>
                    <ext:MenuCommand Text="Delete" Icon="ApplicationFormDelete" CommandName="Delete" meta:resourcekey="DeleteCommandResource1" />
                    <ext:MenuCommand Text="Disable" Icon="ApplicationFormDisable" CommandName="Disable" />
                    <ext:MenuCommand Text="Enable" Icon="ApplicationFormEnable" CommandName="Enable" />
                </Items>
            </Menu>
        </ext:GridCommand>
    </Commands>
    <PrepareToolbar Fn="prepareRecruiter" />
    <Listeners>
        <Command Fn="REDcommand" />
    </Listeners>
</ext:CommandColumn>

谢谢！

您应该使用“button.menu”来访问菜单项。

示例

<%@ Page Language="C#" %> <script runat="server"> protected void Page_Load(object sender, EventArgs e) { if (!X.IsAjaxRequest) { Store store = this.GridPanel1.GetStore(); store.DataSource = new object[] { new object[] { "test", "test" }, new object[] { "test", "test" }, new object[] { "test", "test" } }; } } </script> <!DOCTYPE html> <html> <head runat="server"> <title>Ext.NET v2 Example</title> <script> var prepareToolbar = function (grid, toolbar, rowIndex, record) { var btn = toolbar.items.get(0); btn.menu.items.get(0).disable(); }; </script> </head> <body> <form runat="server"> <ext:ResourceManager runat="server" /> <ext:GridPanel ID="GridPanel1" runat="server"> <Store> <ext:Store runat="server"> <Model> <ext:Model runat="server"> <Fields> <ext:ModelField Name="test1" /> <ext:ModelField Name="test2" /> </Fields> </ext:Model> </Model> </ext:Store> </Store> <ColumnModel runat="server"> <Columns> <ext:Column runat="server" Text="Test 1" DataIndex="test1" /> <ext:Column runat="server" Text="Test 2" DataIndex="test2" /> <ext:CommandColumn runat="server" Width="35"> <Commands> <ext:GridCommand Icon="ApplicationForm"> <Menu> <Items> <ext:MenuCommand Text="Delete" CommandName="Delete" /> <ext:MenuCommand Text="Disable" CommandName="Disable" /> <ext:MenuCommand Text="Enable" CommandName="Enable" /> </Items> </Menu> </ext:GridCommand> </Commands> <PrepareToolbar Fn="prepareToolbar" /> </ext:CommandColumn> </Columns> </ColumnModel> </ext:GridPanel> </form> </body> </html>
