datalist

问题 Can I place a asp:datalist inside a repeater control and databind it for each time its repeated? Using VB.NET btw.. Cheers! --Jonesy 回答1: Steps: 1. Nest the DataList in the Repeater 2. Bind each repeated Datalist during the Repeater's ItemDataBound event 3. Turn off their ViewStates,if they are not required. Update: i.e. Script Side: <asp:Repeater ID="Repeater1" runat="server"> <ItemTemplate> <asp:DataList ID="DataList1" runat="server"> </asp:DataList> </ItemTemplate> </asp:Repeater> In Code:

问题 I have an Asp.net DataList control in my page. It is currently having repeatcolumns set to 4 which will give me 4 columns in each row. But I want to make this responsive and set the value to 1 for smaller screen sizes. Below is my asp.net control: <asp:DataList runat="server" RepeatDirection="Horizontal" RepeatColumns="4" ID="dd" class="vex-res"> How can I achieve this? 回答1: You cannot make DataList to be responsive, because it renders as Table.

问题 I'm debating between using a <select> or <datalist> to display a drop-down list from which the user can select the items. One downside of the <select> tag is that it's inconsistent as it renders differently in different browsers: some browsers it displays with scroll bar, and for some it's a drop-down list. The <datalist> on the other hand seems good but I just want to know if there is any way to disable the text input where the user can type whatever they want in the text box if they don't

问题 Here's a concrete example in 5 short steps: 1) I have built a Data List in the Design view of an "ASCX" file. 2) In the Item Template area of the Data List, I created a 1x3 table, and in each cell I specified as below using Eval(“columnx”) a column (fid) returned through a Stored Procedure. <asp:Label ID="Label1" runat="server" Text='<%# Eval("fid") %>'> In the same manner, I specified other two fields returned by the same stored procedure. 3) I went to the .ASCX.CS (code behind file) and

问题 I've inherited a VB.Net application that I'm testing and the ItemCommand event is not firing... It is a VB.Net 4.0 application. I've searched the web for this error and doubhle checked the code in the application. I know this event is supposed to fire on a postback after the page_load event.

Also you can programmatically change the values of the items that datalist display by updating the datasource of the datalist. An alternative way is using ItemDataBound event. Here in MSDN you can see an example. 回答2: The DataList has an
