[英]Weird behaviour of DropDownList Asp.net
Weird behaviour happening in my DropDownList
Asp.net 我的DropDownList
Asp.net中发生的奇怪行为
My Code: 我的代码:
<asp:DropDownList ID="DDLFromMinutes" runat="server" Width="20%">
<asp:ListItem Text="00" Value="00"></asp:ListItem>
<asp:ListItem Text="15" Value="15"></asp:ListItem>
<asp:ListItem Text="30" Value="30"></asp:ListItem>
<asp:ListItem Text="45" Value="45"></asp:ListItem>
</asp:DropDownList>
However when i run it for example if 15 is the Selected Value i get it Twice in my DropDownList
但是,当我运行它时,例如,如果15是Selected Value,我在DropDownList
得到两次
While Debugging in FireBug get the following: 在FireBug中进行调试时,请获取以下信息:
<select id="ContentPlaceHolder1_DDLFromMinutes" style="width:20%;" name="ctl00$ContentPlaceHolder1$DDLFromMinutes">
<option value="00" selected="selected">30</option>
<option value="15">15</option>
<option value="30">30</option>
<option value="45">45</option>
</select>
Code behind: 后面的代码:
string Frominput = seprateFromTime[1];
string Frommin = Frominput.Substring(0, 2);
DDLFromMinutes.SelectedItem.Text = Frommin;
if (DDLFromMinutes.Items.Count > 0)
{
DDLFromMinutes.SelectedIndex = DDLFromMinutes.Items.IndexOf(DDLFromMinutes.Items.FindByText(Frommin));
}
While saving the Data is use DDLFromMinutes.SelectedItem.Text
Could this be an issue? 保存数据时使用DDLFromMinutes.SelectedItem.Text
这可能是一个问题吗?
do you want to get the value of drop down list? 您想获得下拉列表的价值吗? If so, I think you need to change SelectedItem to SeletedValue. 如果是这样,我认为您需要将SelectedItem更改为SeletedValue。
