Radio Button single selection in Repeater/Datalist_radio button和single select-优快云博客

本文介绍了一种在ASP.NET Repeater控件中实现单选按钮唯一选中的方法。通过结合使用ASP.NET服务器控件及JavaScript，确保在一组单选按钮中仅能选择一项。此解决方案适用于需要在动态生成的列表中处理单选按钮的场景。

Here is the example code snippets : <asp:Repeater ID="rptTest" runat="server" OnItemDataBound="rptTest _ItemDataBound"> <HeaderTemplate> Select Radio buttion </HeaderTemplate> <ItemTemplate> <asp:RadioButton ID="radTest" runat="server" /> </ItemTemplate> </asp:Repeater> On Repeater ItemDataBound event :- protected void rptTest_ItemDataBound(object sender, RepeaterItemEventArgs e) { if (e.Item.ItemType != ListItemType.Item && e.Item.ItemType != ListItemType.AlternatingItem) return; RadioButton rdo = (RadioButton)e.Item.FindControl("radTest"); string script = "SetSingleRadioButton('rptTes t.*Test',this)"; rdo.Attributes.Add("onclick", script); } Java Script for Unique Radio Button :- <script type="text/javascript"> function SetSingleRadioButton(nameregex, current) { re = new RegExp(nameregex); for (i = 0; i < document.forms[0].elements.length; i++) { elm = document.forms[0].elements[i] if (elm.type == 'radio') { if (re.test(elm.name)) { elm.checked = false; } } } current.checked = true; } Hope it Helps …Thanks
