问题描述
大家好，
我正在使用客户端回调机制重新绑定网格并在文本框F2 press(onkeyup event)上显示modelpopup.代码如下:
.aspx页面
Hi every one,
I am using client call back mechanism to rebind the grid and show modelpopup on textbox F2 press(onkeyup event). The code is as follows :
.aspx page
<asp:TextBox ID="txtReasonsForDelay" runat="server" AutoPostBack="false" Text=''<%#Bind("ReasonForDelay")%>'' MaxLength="1000" TextMode="multiline" ToolTip="Enter Reasons For Delay or select list of Reasons."></asp:TextBox>
上面的文本框在窗体视图中.以下数据与gridview中的modelpopup和面板相关.
The above textbox is in form view. The below data is related to modelpopup, panel within gridview
<cc1:ModalPopupExtender ID="modelPopupReason" runat="server" BackgroundCssClass="modalBackground"
TargetControlID="hiddenbuttonSort" PopupControlID="panelReasons" OkControlID=""
CancelControlID="" >

</asp:Panel>
在aspx.cs文件中，在页面加载中:
In aspx.cs file, In Page Load:
if (!IsCallback)
{
TextBox txtReasonsForDelay = (TextBox)frmWorkOrder.FindControl("txtReasonsForDelay");
if (txtReasonsForDelay != null)
{
string getParameters = txtReasonsForDelay.ClientID + "," + modelPopupReason.ClientID + "," + grvReasons.Rows.Count;
//System.Windows.Forms.KeyEventArgs e1 = new System.Windows.Forms.KeyEventArgs(System.Windows.Forms.Keys.F2);
//if ((txtReasonsForDelay)e1.KeyCode == 113)
//{
//}
txtReasonsForDelay.Attributes.Add("onkeyup", "txtReasonsForDelayKeyPress1('" + getParameters + "','"+ System.Windows.Forms.Keys.F2 +"')");
}
ClientScriptManager cm = Page.ClientScript;
String cbReference = cm.GetCallbackEventReference(this, "arg", "EndGetData", "context", false);
cm.GetCallbackEventReference(this, "arg", "ReceiveServerData", "");
String callbackScript = "function txtReasonsForDelayKeyPress1(arg, context) {" + cbReference + "; }";
cm.RegisterClientScriptBlock(this.GetType(), "txtReasonsForDelayKeyPress1", callbackScript, true);
}
the client call back related procedures :
public string GetCallbackResult()
{
return _Callback;
}
public void RaiseCallbackEvent(string eventArgument)
{
grvReasons.DataBind();
_Callback = grvReasons.Rows.Count.ToString();
}
javascript/client函数来调用服务器函数:
javascript/client function to call server function:
function EndGetData(arg,context)
{
if(window.event.keyCode==113)
{
$find('ctl00_ContentPlaceHolder1_modelPopupReason').show();
}
问题:
1)当在与原因"记录相关的母版中创建新条目时，我调试并发现绑定正常工作.但是，它无法在modelpopup/gridview中显示新添加的记录.
2)我无法捕获键码，反而在javascript中出现期望的对象"错误
请解决我的问题或提出建议，因为我正在使用回调概念.
Problem :
1) when a new entry is made in masters related to the "reasons" record, i debug and find the bind works properly. But, it is unable to show the newly added records in modelpopup/gridview.
2) I am unable to capture keycode instead i get error as "object expected" in javascript
Please solve my problem or give some suggesions as i am using call back concept.
