在下拉列表中被另一个过滤掉的findbytext?

问题描述

大家好，我有两个下拉列表，一个列表是根据另一个列表过滤的，它的工作很好，我想按文本搜索两个下拉列表，所以我使用以下代码:

Hi every body , I have two drop down list one is filtrated based on the other its work fine , i want to search in my two dropdowns by text so im using this code :

ddlsociete.SelectedIndex = ddlsociete.Items.IndexOf(ddlsociete.Items.FindByText("sapmleofSociete"));


ddlba.SelectedIndex = ddlba.Items.IndexOf(ddlba.Items.FindByText(("sampleOFba")));

ddlba是根据ddlsoc的selecteditem筛选的，当我运行以下代码时，我的ddlsoc的selectedindex带有"sampleofsociete"，但ddlba始终为空?我知道，因为它的药网有任何物品，所以如何获取

ddlba is filtred based on selecteditem of ddlsoc , when i run the code below i have ddlsoc with selectedindex with "sampleofsociete" but ddlba its always empty ? i understand because it dosenet have any items so how to get
selected item from selected index ??

推荐答案

ddlsociete.SelectedIndex = ddlsociete.Items.IndexOf(ddlsociete.Items.FindByText("sapmleofSociete"));

Fillddlba();
ddlba.SelectedIndex = ddlba.Items.IndexOf(ddlba.Items.FindByText(("sampleOFba")));


void Fillddlba()
{
// write here code to fill items on second dropdown base on selected value of first dropdown
}

希望对您有用，否则让我知道.
