我试图找到其在直放站虽然用户控件呈现的文本框的值,即中继器具有为用户控件的占位符,该用户控件里面就是文本框标记确实存在。 我以前直接与内前直放站的文本框,这是相当简单的做到了这一点,我想知道为什么这显然不能以同样的方式来完成。 下面是与中继器,其中包含一个占位符的默认页面...
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
<form class="formee">
<fieldset>
<legend>Faculty Information</legend>
<div class="grid-4-12">
<asp:Label ID="lblFirstName1" runat="server" Text="First Name"></asp:Label>
<asp:Label ID="lblFirstName2" runat="server" Text="" ></asp:Label>
<asp:Label ID ="lblSalary" runat="server" Text="" ClientIDMode="Static"></asp:Label>
</div>
<div class="grid-6-12">
<asp:Label ID="lblLastName1" runat="server" Text="Last Name"></asp:Label>
<asp:Label ID="lblLastName2" runat="server" Text=""></asp:Label>
</div>
</fieldset>
</form>
<div id="repeaterDiv">
<asp:Repeater ID="rptBudget" runat="server" ClientIDMode="Static">
<ItemTemplate>
<asp:PlaceHolder ID="phBudget" runat="server" EnableViewState="true" />
<br />
</ItemTemplate>
</asp:Repeater>
<asp:Button ID="btnAddBudgetControl" runat="server" Text="Add"
CausesValidation="false" OnClick="AddBudgetControl" CssClass="addBudgetControl"/>
<asp:Button ID="btnDisplayEntries" runat="server" Text="Display Entries" CausesValidation="false" OnClick="DisplayEntries" />
</div>
<div>
<asp:TextBox ID="txtTotalPercent" runat="server" ClientIDMode="Static"></asp:TextBox>
<asp:TextBox ID="txtGrandTotal" runat="server" ClientIDMode="Static"></asp:TextBox>
<asp:Label ID="lblCtrls" runat="server" Text=""></asp:Label>
</div>
而哪些插入占位符的地方的用户控件...
<fieldset>
<legend>Faculty Salary Form</legend>
<table cellspacing="10" id="values">
<tr>
<td>
<asp:Label ID="lblServiceType" runat="server" Text="Service"></asp:Label>
<asp:DropDownList runat="server" ID="ddlServiceType" CssClass="serviceType" />
</td>
<td>
<asp:Label ID="lblSpeedCode" runat="server" Text="Speed Code"></asp:Label>
<asp:DropDownList runat="server" ID="ddlSpeedCode" CssClass="speedType" />
</td>
<td>
<asp:Label ID="lblPercentage" runat="server" Text="Percentage"></asp:Label>
<asp:Textbox ID="txtPercentage" runat="server" CssClass="percentCommitment" ClientIDMode="Static" EnableViewState="true" />
</td>
<td>
<asp:Label ID="lblTotal" runat="server" Text="Total"></asp:Label>
<asp:TextBox ID="txtTotal" runat="server" CssClass="amountCommitment" ClientIDMode="Static" EnableViewState="true"/>
</td>
<td>
<asp:Button ID="btnRemove" runat="server" Text="Remove Item" OnClick="RemoveItem" ClientIDMode="Static" CssClass="btnRemove" />
</td>
</tr>
<tr>
</tr>
</table>
</fieldset>
......但是,当下面的代码显示按钮的OnClick运行时,我总是对任何和空值的用户控件的所有文本框(和下拉菜单)...
protected void DisplayEntries(object sender, EventArgs e)
{
foreach (RepeaterItem repeated in rptBudget.Items)
{
TextBox txtPercentage = (TextBox)repeated.FindControl("txtPercentage");
if (txtPercentage == null)
{
lblCtrls.Text += " null; ";
}
else
{
lblCtrls.Text += txtPercentage.Text + "; ";
}
}
}
什么是访问这些值的最佳方式? 谢谢。
