我想使搜索出来的关键字变色,不知道该怎么实现,我是这么写的,可是不行
protected void DataList1_ItemDataBound(object sender, DataListItemEventArgs e)
{
Label lb = (Label)e.Item.FindControl( "goodsnameLabel ");
Label lb1=(Label)e.Item.FindControl( "goodspriceLabel ");
string a = Session[ "textbox "].ToString();//这是另一页TextBox里记录下的关键字
lb.Text.Replace(a, " <font color= '#ff7f50 '> "+a+ " </font> ");
lb1.Text.Replace(a, " <font color= '#ff7f50 '> " + a + " </font> ");
}
这样也不行:
lb.Text.Replace( "a ", " <font color= '#ff7f50 '> a </font> ");
lb1.Text.Replace( "a ", " <font color= '#ff7f50 '> a </font> ");
请问该怎么办呢?是不是不能写在ItemDataBound里还是语法错误
还有问一下,在查询时,我想让TextBox里输入的字符,有任意一个字符在数据库里存在就行,
string sql = "select * from goods where goodsvar like '% " + a + "% ' or goodsname like '% " + a+ "% ' "; 这样写的话是数据库里的东西包含TextBox里输入的所有字符才成功,我想实现包含TextBox里输入的任一字符就匹配成功,请问该怎么实现呢?谢谢所有回答的朋友
------解决方案--------------------lb.Text.Replace(a, " <font color= '#ff7f50 '> "+a+ " </font> ");
lb1.Text.Replace(a, " <font color= '#ff7f50 '> " + a + " </font> ");
换为
lb.Text = lb.Text.Replace(a, " <font color= '#ff7f50 '> "+a+ " </font> ");
lb1.Text = lb1.Text.Replace(a, " <font color= '#ff7f50 '> " + a + " </font> ");
------解决方案--------------------protected void DataList1_ItemDataBound(object sender, DataListItemEventArgs e)
{
Label label1;
string a = "But ";
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
label1 = (Label)e.Item.FindControl( "Label1 ");
label1.Text = label1.Text.Replace(a, " <font color= '#ff7f50 '> " + a + " </font> ");
}
}
