我的 GridViews 连接到它们各自的 LinqDataSource(LinqDataSourceMale & LinqDataSourceFemale) 是

我的 SearchClick 事件代码是：
protected void ButtonSearch_Click(object sender, EventArgs e)
{
using(BerouDataContext Data = new BerouDataContext())
{
if (DropDownListGender.SelectedItem.Text == "Male")
{
int age = Convert.ToInt32(DropDownListAge.Text);
string education = DropDownListEducation.Text.ToString();
string maritalstatus = DropDownListMaritalStatus.Text.ToString();
string caste = DropDownListCaste.Text.ToString();
string city = DropDownListCity.ToString();
var SearchResultBoys = Data.Males.Where(tan =>
(tan.Age == age)
&& (tan.Education.Contains(education))
&& (tan.Group.Contains(maritalstatus))
&& (tan.Caste.Contains(caste)));
GridViewMale.DataSourceID = "";
GridViewMale.DataSource = SearchResultBoys;
GridViewMale.DataBind();
}
else if (DropDownListGender.SelectedItem.Text == "Female")
{
int age = Convert.ToInt32(DropDownListAge.Text);
string education = DropDownListEducation.Text.ToString();
string maritalstatus = DropDownListMaritalStatus.Text.ToString();
//var religion = DropDownListReligion.Text.ToString();
string caste = DropDownListCaste.Text.ToString();
string city = DropDownListCity.ToString();
var SearchResultGirls = Data.Females.Where(tan =>
(tan.Age == age)
&& (tan.Education.Contains(education))
&& (tan.Group.Contains(maritalstatus))
&& (tan.Caste.Contains(caste)));
GridViewFemale.DataSourceID = "";
GridViewFemale.DataSource = SearchResultGirls;
GridViewFemale.DataBind();
}
}
}
我无法在gridview中显示数据，searchClickEvent后gridview不出现，请帮助。
