Question

我在asp updatePanel中有一个DevExpress gridView。

 <asp:ScriptManager ID="ScriptManager1" runat="server" />
 <asp:UpdatePanel ID="upWWWGrid" runat="server" UpdateMode="Conditional">
    <ContentTemplate>
        <div>
            <dx:ASPxGridView ID="grdWWW" runat="server" KeyFieldName="WWWID" AutoGenerateColumns="false" Visible="false" OnRowInserting="grdWWW_RowInserting" OnRowInserted="grdWWW_RowInserted">   
                 <Columns>
                    <dx:GridViewCommandColumn VisibleIndex="0" Caption=" ">
                        <ClearFilterButton Visible="True" />
                        <NewButton Visible="true" />
                        <EditButton Visible="true" />
                        <DeleteButton Visible="true" />
                    </dx:GridViewCommandColumn>
                    <dx:GridViewDataColumn FieldName="WWWID" VisibleIndex="1" Caption="WWW ID">
                        <EditFormSettings Visible="False" />
                    </dx:GridViewDataColumn>  
                    <SettingsEditing Mode="EditFormAndDisplayRow" EditFormColumnCount="2" />
                    <SettingsPager PageSize="20" AlwaysShowPager="true" />
                    <SettingsBehavior AllowSort="true" ConfirmDelete="true" />
                    <Settings ShowFilterRow="true" ShowTitlePanel="true" />
                </Columns>
            </dx:ASPxGridView>
        </div>
    </ContentTemplate>
</asp:UpdatePanel>

我想通过执行此操作在onRowInserted（）事件中触发javascript警报以下内容：

string Message = "Hello World!"; 
ScriptManager.RegisterStartupScript(Page, this.GetType(), "alert", String.Format("alert('{0}');", Message), true);

但似乎警报从未注册过。我相信这个问题与gridView使用Callbacks执行所有操作有关。知道如何在创建新记录后触发此警报吗？我遇到的大多数示例演示了如何使用客户端SelectionChanged事件和onCustomCallback来执行此操作。

您可以尝试这样的事情：

protected void Grid_RowInsertedEvent(object sender, ASPxDataInsertedEventArgs e) 
{
    JSProperties["cp_RowInserted"] = true;
    ...
}

// I prefer this in grid's Init event handler but you can place it in 
// RowInserted as well
ClientSideEvents.EndCallback = 
    @"function(s,e)
    {
        if(s.cp_RowInserted!=null)
        {
            alert('row inserted');
            s.cp_RowInserted=null;
        }
    };";

Answer 2

您可以在行数据绑定事件上注册网格的onclick事件。以下是您可以使用的代码片段

protected void Grid1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{         
}
else if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Attributes.Add("onclick", "alert('I am here')");
