单击按钮后,Rowcommand不会触发

Question

我已经找到了解决方案,我只想发布它,这对某些人来说可能有用

这是使用命令的按钮

<dxwgv:ASPxGridView ID="gdvxUsers" runat="server" AutoGenerateColumns="False" Width="100%" KeyFieldName="UserName" onrowcommand="gdvxUsers_RowCommand">
        <Columns>
        <dxwgv:GridViewDataTextColumn Caption="Edit" VisibleIndex="0" Width="0px">
            <DataItemTemplate>
                <asp:ImageButton ID="imbEdit" runat="server"
                    CommandName = "Edit"
                    ImageUrl="~/images/icon/Edit-icon.png" ClientIDMode="Static" />
            </DataItemTemplate>
        </dxwgv:GridViewDataTextColumn>
</dxwgv:ASPxGridView>

    protected void gdvxUsers_RowCommand(object sender, DevExpress.Web.ASPxGridView.ASPxGridViewRowCommandEventArgs e)
    {
        switch (e.CommandArgs.CommandName)
        {
            case "Edit":



            break;
        }
    }

单击按钮时,行命令不会触发.

问题是,Page_Load我Databind()在gridview 上使用命令我正在使用rowcommand,似乎之后DataBind(),rowcommand取消了.

    protected void Page_Load(object sender, EventArgs e)
    {
            gdvxUsers.DataSource = GetAllUserAndRole();
            gdvxUsers.DataBind();            
    }

所以我通过仅在第一次加载时绑定数据来解决此问题.

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            gdvxUsers.DataSource = GetAllUserAndRole();
            gdvxUsers.DataBind();
        }
    }
