从上面的标题，我的代码第一次page_load，没有问题，它显示正确，但在我点击按钮更改语言后，它消失（只显示标题）。我花了大约一个星期才发现但仍然无法找到发生的事情。 如果可见数据大于1，则其工作正常。
编辑： 忘了把我的页面加载方法
protected void Page_Load(object sender, EventArgs e)
{
NoResult.Visible = false;
Get_Data();
}
protected void Get_Data()
{
DBCAD.Service1 myCADDB = new DBCAD.Service1();
myCADDB.UseDefaultCredentials = true;
string result = "";
//set web service proxy
if (!GlobalVariable_CCCNS.filterOrNot)
{
//invoke web service method
result = myCADDB.CallCardStatus_Filter_CCCNSEMBILAN_ALL();
}
else
{
GlobalVariable_CCCNS.FilterDC = DropDownList1.SelectedValue;
//invoke web service method
if (GlobalVariable_CCCNS.FilterDC == "CCC NS ALL")
{
result = myCADDB.CallCardStatus_Filter_CCCNSEMBILAN_ALL();
}
else
{
result = myCADDB.CallCardStatus_Filter(GlobalVariable_CCCNS.FilterDC);
}
}
//read the response data and put in xml document
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(result);
string mypath = Server.MapPath(@"Data.xml");
//XmlTextReader reader = new XmlTextReader ("DBCAD.xml");
xmlDoc.Save(mypath);
//set the data set
DataSet ds = new DataSet();
ds.ReadXml(mypath);
//Open hidden column
CallCardStatus.Columns[0].Visible = true;
if (ds.Tables.Count > 0)
{
//list out the result to Data Grid
CallCardStatus.DataSource = ds;
CallCardStatus.DataBind();
}
else
{
NoResult.Visible = true;
}
//Clear Unwanted Column
CallCardStatus.Columns[0].Visible = false;
}
这是我的RowDataBound
string lastRow = "";
protected void CallCardStatus_RowDataBound(object sender, GridViewRowEventArgs e)
{
//Many item with same id but different status, I just want to visible and get the first row for each id.
if (e.Row.RowType == DataControlRowType.DataRow)
{
var thisRow = e.Row;
if (thisRow.Cells[0].Text == lastRow)
{
e.Row.Visible = false;
}
lastRow = thisRow.Cells[0].Text;
}
}
这是我的语言马来语和英语的RadioButton
protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e)
{
GlobalVariable_CCCNS.cultureName = RadioButtonList1.SelectedValue.ToString();
Page.Culture = GlobalVariable_CCCNS.cultureName;
Page.UICulture = GlobalVariable_CCCNS.cultureName;
if (GlobalVariable_CCCNS.cultureName == "ms-MY")
{
Label2.Visible = false;
Label2.Text = "Kawalan Status Kad Panggilan";
Label2.Visible = true;
}
else
{
Label2.Visible = false;
Label2.Text = "CallCard Status Monitoring";
Label2.Visible = true;
}
Page_Render();
}
protected void Page_Render()
{
Page.Culture = GlobalVariable_CCCNS.cultureName;
Page.UICulture = GlobalVariable_CCCNS.cultureName;
ALL.Text = GetLocalResourceObject("ALLResource1.Text").ToString();
Label1.Text = GetLocalResourceObject("Label1Resource1.Text").ToString();
NoResult.Text = GetLocalResourceObject("NoResultResource1.Text").ToString();
DBCAD.Service1 myCADDB = new DBCAD.Service1();
myCADDB.UseDefaultCredentials = true;
string result = "";
//set web service proxy
if (!GlobalVariable_CCCNS.filterOrNot)
{
//invoke web service method
result = myCADDB.CallCardStatus_Filter_CCCNSEMBILAN_ALL();
}
else
{
GlobalVariable_CCCNS.FilterDC = DropDownList1.SelectedValue;
//invoke web service method
if (GlobalVariable_CCCNS.FilterDC == "CCC NS ALL"){
result = myCADDB.CallCardStatus_Filter_CCCNSEMBILAN_ALL();
}else{
//invoke web service method
result = myCADDB.CallCardStatus_Filter(GlobalVariable_CCCNS.FilterDC);
}
}
//read the response data and put in xml document

string mypath = Server.MapPath(@"Data.xml");
//XmlTextReader reader = new XmlTextReader ("DBCAD.xml");

//CallCardStatus.DataBind();
//Open hidden column
CallCardStatus.Columns[0].Visible = true;
if (ds.Tables.Count > 0)
{
//list out the result to Data Grid
CallCardStatus.DataSource = ds;
CallCardStatus.Columns[2].HeaderText = GetLocalResourceObject("ButtonFieldResource1.Text").ToString();
CallCardStatus.Columns[3].HeaderText = GetLocalResourceObject("BoundFieldResource3.HeaderText").ToString();
CallCardStatus.Columns[4].HeaderText = GetLocalResourceObject("BoundFieldResource4.HeaderText").ToString();

CallCardStatus.Columns[9].HeaderText = GetLocalResourceObject("BoundFieldResource9.HeaderText").ToString();
CallCardStatus.DataBind();
}
else
{
NoResult.Visible = true;
}
//Clear Unwanted Column
CallCardStatus.Columns[0].Visible = false;
}
任何人都可以提供帮助吗？谢谢.Siti ..：）
答案 0 :(得分：1)
为了清理遗留代码，我建议您使用以下内容:(清理代码将有助于您更轻松地发现错误）
GridView 绑定数据绑定控件的最佳做法是在Page_Load事件中：
protected void Page_Load(object sender, EventArgs e)
{
if (!this.IsPostBack)
{
// in this method u will bind your GridView
this.BindGrid();
}
}
除非我遗漏了某些内容，否则Page_Render方法中的代码将用于呈现GridView，并且该代码在Get_Data方法中重复。您可以将代码专用于将GridView绑定在一个方法中。
现在，您只需在内容发生变化时重新绑定GridView，例如，如果您允许用户修改GridView条记录。否则，您不应该重新绑定它。 （只要您的网页有EnableViewState="true"）
用于本地化GridView列的代码可以移至GridVew.DataBound事件。或者甚至更好，委托逻辑将视图本地化为您的标记，为此，您可以在GridView中创建模板化列。
示例：
<asp:GridView runat="server" DataSourceID="lds" ID="gv"
AutoGenerateColumns="false"
>
<Columns>
<asp:TemplateField>
<HeaderTemplate>
<asp:Label Text="<%$ Resources: your_resource_file_name_without_extension, your resource_key %>" runat="server" />
</HeaderTemplate>
<ItemTemplate>
<asp:Label ID="a_meaningfull_name" Text='<%# Eval("your_field_name") %>' runat="server" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
Page.InitializeCulture方法的页面语言：请注意，您只需在此方法中设置this.UICulture = culture;和this.Culture = culture;
protected override void InitializeCulture()
{
// you have to call Request.Form, because at this point in the page life cycle, the page viewstate has not been loaded yet
var culture = this.Request.Form["RadioButtonList1"];
if (!string.IsNullOrWhiteSpace(culture))
{
// if the values of your list are culture specific (ie. en-US, es-MX, etc) you can uncomment the following line
// this.Culture = culture;
this.UICulture = culture;
base.InitializeCulture();
}
}
使用此方法，不需要RadioButtonList1_SelectedIndexChanged事件。您在此事件中放置的代码不是必需的。
此代码：
if (GlobalVariable_CCCNS.cultureName == "ms-MY")
{
Label2.Visible = false;
Label2.Text = "Kawalan Status Kad Panggilan";
Label2.Visible = true;
}
else
{
Label2.Visible = false;
Label2.Text = "CallCard Status Monitoring";
Label2.Visible = true;
}
可以使用标记轻松消除:(请注意，您需要为要在应用程序中使用的每种语言创建一个资源文件，to learn more about ASP.Net Globalization click here）
使用全球资源
<!-- Assuming global resources -->
<asp:Label runat="server" ID="Label2" Text="<%$ Resources: your_resource_file_name_without_extension, your_resource_key %>" />
您的全局资源文件如下所示：
<data name="your_resource_key" xml:space="preserve">
<value>your text</value>
</data>
使用本地资源
<!-- Assuming local implicit resources -->
<asp:Label runat="server" ID="Label2" meta:resourcekey="base_name_of_your_resource_key" Text="default value used to render the control at design time in VS" />
在这种情况下，您的本地资源文件将如下所示：
<data name="base_name_of_your_resource_key.Text" xml:space="preserve">
<value>your text</value>
</data>
您无需在Page_Render();活动中致电RadioButtonList1_SelectedIndexChanged
