如何在下拉列表中选择文本时禁用另一个下拉列表？ [英] How to disable another dropdown list when text is select in a dropdownlist?

问题描述

由于select是供客户选择值，我希望第二个下拉列表无法点击



我尝试过：



DdlTerm.Enabled = false;

DdlTerm.Items.Clear（）;







if（DDlLoanType.Text！=选择）

{


string query = string.Format（选择LoanTerm，来自LoanRates的LoanRate，其中LoanType ='+ DDlLoanType.Text +'）;

BindDropDownList（DdlTerm，query，LoanTerm ，LoanRate，选择）;

DdlTerm.Enabled = true;

}

其他

{



DdlTerm.Enabled = false;

DdlTerm.Items.Clear（）;

}

解决方案

嗨朋友，

As select is for customers to select values, I want the second dropdown list to be unclickable

What I have tried:

DdlTerm.Enabled = false;
DdlTerm.Items.Clear();



if (DDlLoanType.Text != "Select")
{

string query = string.Format("select LoanTerm, LoanRate from LoanRates where LoanType = '" + DDlLoanType.Text + "'");
BindDropDownList(DdlTerm, query, "LoanTerm", "LoanRate", "Select");
DdlTerm.Enabled = true;
}
else
{

DdlTerm.Enabled = false;
DdlTerm.Items.Clear();
}
