下拉选择值问题 [英] Drop down Selected Value Problem

问题描述

我通过在其中添加一个下拉控件来扩展了CreateUserWizard控件.
我已经在页面加载一次中加载了下拉菜单，如下所示:

I have Extendeed the CreateUserWizard controll by adding a dropdown controll in it.
I have loaded dropdown once in a page load as

if(!page.ispostback())
{ ((DropDownList)RegisterUser.CreateUserStep.ContentTemplateContainer.FindControl("ddlTestType")).Items.Clear();
        ((DropDownList)RegisterUser.CreateUserStep.ContentTemplateContainer.FindControl("ddlTestType")).DataSource = TestTypeSectionManager.getTestTypes();
        ((DropDownList)RegisterUser.CreateUserStep.ContentTemplateContainer.FindControl("ddlTestType")).DataBind();
}

问题是，当我单击创建用户按钮并获得其选中的值时，它总是返回空值.但是未从数据库绑定的其他下拉列表提供了正确的选定值.
我得到选定的值作为

Problem is that when I click the Create User Button and get its selected vale it always return value Empty value.But other dropdowns that are not bind from DB gives correct selected values.
I get selected value as

regUser.TestType = ((DropDownList)RegisterUser.CreateUserStep.ContentTemplateContainer.FindControl("ddlTestType")).SelectedValue.ToString();

请提供任何帮助.

推荐答案

if(!page.ispostback())
{ ((DropDownList)RegisterUser.CreateUserStep.ContentTemplateContainer.FindControl("ddlTestType")).Items.Clear();
        ((DropDownList)RegisterUser.CreateUserStep.ContentTemplateContainer.FindControl
("ddlTestType")).DataSource = TestTypeSectionManager.getTestTypes();
Try this.
<pre>((DropDownList)RegisterUser.CreateUserStep.ContentTemplateContainer.FindControl(&quot;ddlTestType&quot;)).datatextfield = "TestTypesName"

((DropDownList)RegisterUser.CreateUserStep.ContentTemplateContainer.FindControl("ddlTestType")).datavaluefield = "TestTypesId"

(((DropDownList)RegisterUser.CreateUserStep.ContentTemplateContainer.FindControl("ddlTestType")).DataBind();
}

((DropDownList)RegisterUser.CreateUserStep.ContentTemplateContainer.FindControl("ddlTestType")).DataBind();
}
