Each college has multiple courses which has been displayed in second column.</p> <p><strong>Restriction to be imposed on user selection:</strong> </p> <p>When user selects a college (say MIT), He should be allowed to select courses corresponding to selected college only (computer science &amp; mechanical engg in this case).</p> <p>How can I achieve this functionality using jQuery ?</p> <p>I am binding following data into nested repeater.</p> <pre><code> public string currentCollege { get; set; } Dictionary&lt;string, List&lt;string&gt;&gt; colleges; class College { public College(string s) { Course = s; } public string Course { get; set; } } protected void Page_Load(object sender, EventArgs e) { colleges = new Dictionary&lt;string, List&lt;string&gt;&gt;(); colleges.Add("mit", new List&lt;string&gt;(new string[] { "computer science", "mechanical engg." })); colleges.Add("caltech", new List&lt;string&gt;(new string[] { "electrical engg", "cryptography"})); colleges.Add("harvard", new List&lt;string&gt;(new string[] { "language", "arts", "science" })); rptColleges.DataSource = colleges; rptColleges.DataBind(); } protected void rptColleges_ItemDataBound(object sender, RepeaterItemEventArgs e) { if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) { Repeater rptCourseNow = (e.Item.FindControl("rptCourses") as Repeater); rptCourseNow.DataSource = colleges[currentCollege]; rptCourseNow.DataBind(); } } </code></pre> <p>the markup is as follows -</p> <pre><code> &lt;asp:Repeater ID="rptColleges" runat="server" OnItemDataBound="rptColleges_ItemDataBound"&gt; &lt;HeaderTemplate&gt; &lt;table&gt; &lt;/HeaderTemplate&gt; &lt;ItemTemplate&gt; &lt;tr&gt; &lt;td&gt; &lt;asp:RadioButton ID="rbCollege" runat="server" value=&lt;%# DataBinder.Eval((KeyValuePair&lt;string, List&lt;string&gt;&gt;)Container.DataItem, "Key") %&gt; /&gt; &lt;%# currentCollege = (string)DataBinder.Eval((KeyValuePair&lt;string, List&lt;string&gt;&gt;)Container.DataItem, "Key") %&gt; &lt;/td&gt; &lt;td&gt; &lt;asp:Repeater ID="rptCourses" runat="server"&gt; &lt;HeaderTemplate&gt; &lt;ul&gt; &lt;/HeaderTemplate&gt; &lt;ItemTemplate&gt; &lt;li&gt; &lt;asp:RadioButton ID="rbCourse" value="&lt;%#Container.DataItem %&gt;" runat="server" /&gt; &amp;nbsp; &lt;%#Container.DataItem %&gt; &lt;/li&gt; &lt;/ItemTemplate&gt; &lt;FooterTemplate&gt;&lt;/ul&gt;&lt;/FooterTemplate&gt; &lt;/asp:Repeater&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/ItemTemplate&gt; &lt;FooterTemplate&gt;&lt;/table&gt;&lt;/FooterTemplate&gt; &lt;/asp:Repeater&gt; </code></pre> <p>Thank you for your help.</p>

    1. COPlease tell us what your application is trying to accomplish. We are not your colleagues that know what you are trying to do. Right now you question sounds kinda vague.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
