Maskeditextender未在gridview中动态绑定到文本框 [英] Maskeditextender is not being bound to textbox dynamically in gridview
问题描述
我的gridview中有一个Masked编辑扩展器。我根据类型动态显示这个gridview，如果类型为T，则只显示文本框，如果类型为DT，则显示带日历的文本框。
我正在使用相同的文本框，并在网格行数据绑定事件中，我隐藏并显示日历按钮。但是如果我在gridview中给maskededitextender，那么掩码也会应用于非日期字段。
我尝试给出一个虚拟文本框并将其作为targetcontrolid for maskededtextender和rowdatabound事件，如果类型是日期，我将maskededitextender的targetcontrolid设置为我的文本框。但它没有用。
有人可以帮我吗？
什么我试过了：
下面是rowdatabound事件代码：
protected void grd_RowDataBound （对象发送者，GridViewRowEventArgs e）
{
尝试
{
if（e.Row.RowType = = DataControlRowType.DataRow）
{
MaskedEditExtender ME =（MaskedEditExtender）e.Row.FindControl（MaskedEditExtender1）;
TextBox txtValue1 =（TextBox）e.Row.FindControl（txtValue1）;
TextBox txttest =（TextBox）e.Row.FindControl（txttest）;
HiddenField hfInputType =（HiddenField）e.Row.FindControl（hfInputType）;
ImageButton imgBtnFromDate =（ImageButton）e.Row.FindControl（imgBtnFromDate）;
ME.TargetControlID = txttest.ClientID;
if（hfInputType.Value ==DT）
{
txtValue1.Style.Add（HtmlTextWriterStyle.Display，block） ;
imgBtnFromDate.Style.Add（HtmlTextWriterStyle.Display，block）;
ME.TargetControlID = txtValue1.ClientID;
}
else if（hfInputType.Value ==U）
{
txtValue1.Style。添加（HtmlTextWriterStyle.Display，block）;
imgBtnFromDate.Style.Add（HtmlTextWriterStyle.Display，none）;
}
}
}
}
Asp.net代码：
< asp：ImageButton ID =imgBtnFromDaterunat =serverStyle =display ：noneImageUrl =〜/ App_Themes / Black / Images / Calendar.png/>
< cc1：CalendarExtender ID =ceFromDatePopupButtonID =imgBtnFromDaterunat =server

I have a Masked edit extender in my gridview. I am displaying this gridview dynamically based on types, If the type is "T" it displays only textbox, if the type is "DT" it displays textbox with calendar.
I am using the same textbox, and in grid row databound event, I am hiding and showing the calendar button. But if I give the maskededitextender in the gridview, the mask is being applied for the nondate fields also.
I tried by giving a dummy textbox and make it as targetcontrolid for the maskededtextender and in rowdatabound event, I am setting the targetcontrolid of the maskededitextender to my textbox if the type is date. But it is not working.
can anyone please help me on this?
What I have tried:
Below is the rowdatabound event code:
protected void grd_RowDataBound(object sender, GridViewRowEventArgs e)
{
try
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
MaskedEditExtender ME = (MaskedEditExtender)e.Row.FindControl("MaskedEditExtender1");
TextBox txtValue1 = (TextBox)e.Row.FindControl("txtValue1");
TextBox txttest = (TextBox)e.Row.FindControl("txttest");
HiddenField hfInputType = (HiddenField)e.Row.FindControl("hfInputType");
ImageButton imgBtnFromDate = (ImageButton)e.Row.FindControl("imgBtnFromDate");
ME.TargetControlID = txttest.ClientID;
if(hfInputType.Value=="DT")
{
txtValue1.Style.Add(HtmlTextWriterStyle.Display, "block");
imgBtnFromDate.Style.Add(HtmlTextWriterStyle.Display, "block");
ME.TargetControlID = txtValue1.ClientID;
}
else if(hfInputType.Value=="U")
{
txtValue1.Style.Add(HtmlTextWriterStyle.Display, "block");
imgBtnFromDate.Style.Add(HtmlTextWriterStyle.Display, "none");
}
}
}
}
Asp.net code:
<asp:ImageButton ID="imgBtnFromDate" runat="server" Style="display: none" ImageUrl="~/App_Themes/Black/Images/Calendar.png" />
<cc1:CalendarExtender ID="ceFromDate" PopupButtonID="imgBtnFromDate" runat="server"
TargetControlID="txtValue1">
<cc1:MaskedEditExtender ID="MaskedEditExtender1" runat="server" AcceptNegative="Left"
DisplayMoney="Left" Mask="99/99/9999" MaskType="Date" MessageValidatorTip="true"
>
推荐答案
删除此行
remove this line
ImageButton imgBtnFromDate = (ImageButton)e.Row.FindControl("imgBtnFromDate");
ME.TargetControlID = txttest.ClientID; // this is global scope, it will be applied to all controls.
if(hfInputType.Value=="DT")
{
