    <p>I am new to .Net platform and I am stuck in retrieving controls from .aspx pages since two days.</p> <p>I am trying to get all the <code>controls</code> from all the <code>.aspx</code> pages in my website. So for that I create the object of the Page from the string of class name which I get from my database. I have already stored the <code>class names</code> of .aspx.cs files in database</p> <p>The code in C# is:</p> <pre><code>Page obj = (Page)Activator.CreateInstance(null, string ClassName).Unwrap(); </code></pre> <p>The string <code>"ClassName"</code> is taken from the database.</p> <p>Now during Debug time I can see that there are <code>controls</code> in the <code>obj</code> but I get <code>0</code> in <code>controls.count</code>. I guess this is because the controls are still <code>not initialized</code>.</p> <p><strong><em>Image 1 during debug time</em></strong><img src="https://i.stack.imgur.com/Av6KK.jpg" alt="Image 1 during debug time">:</p> <p><strong><em>Image 2 during debug time showing my controls</em></strong><img src="https://i.stack.imgur.com/58NaA.jpg" alt="Image 2 during debug time showing my controls"></p> <p>My code looks like this.</p> <pre><code>Page obj = (Page)Activator.CreateInstance(null, string ClassName).Unwrap() List&lt;string[]&gt; fieldsNotInDB = GetControlCollections(obj) </code></pre> <p>This is my <code>function</code> to get all the <code>controls</code> from the <code>Page obj</code></p> <pre><code>public List&lt;string[]&gt; GetControlCollections(Page p) { List&lt;string[]&gt; controlList = new List&lt;string[]&gt;(); IterateControls(p.Controls, controlList); return controlList; } public void IterateControls(System.Web.UI.ControlCollection page, List&lt;string[]&gt; controlList) { foreach (System.Web.UI.Control c in page) { if (c.ID != null) { string []s=new string[2]; s[0]=c.ID; s[1]=c.GetType().ToString(); controlList.Add(s); } if (c.HasControls()) { IterateControls(c.Controls, controlList); } } } </code></pre> <p>How do I get the <code>Controls</code> from my <code>obj</code>?</p>

    1. COAs a personal opinion - when using `Activator.CreateInstance(..)` you should be asking yourself "Am I bending the framework *to* hard..?"

    2. COI have one asp page from which I will be selecting other asp pages and then view all the controls in it and assign appropriate rights to it. So for that I need some dynamic way of selecting a page and get its controls.

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.
