    <p>Traditionally I use the regular asp.net website (created using the File > New Website). Recently, I opted to work off of a full fledged project (created using File > New Project > ASP.net Web Application).</p> <p>I've been using the same custom controls for years without incident. I simply create the new website, place my CustomControls.cs file in the App_Code directory, add one line to the web.config file and I can use all of my custom server controls. When I try that with my web project I get the following error</p> <blockquote> <p>Error 225 The type or namespace name 'DTF' could not be found in the global namespace (are you missing an assembly reference?) D:[Project Location On Drive]\AgIn02.aspx.designer.cs</p> </blockquote> <p>My custom control file looks like this</p> <pre><code>using System; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using AjaxControlToolkit; using System.Text; using System.IO; using System.Text.RegularExpressions; namespace DTF.Web.UI { public class IntOnlyBox : TextBox { private RequiredFieldValidator rfv; private ValidatorCalloutExtender vce; private AjaxControlToolkit.FilteredTextBoxExtender ftb; private string strInvalidMessage = ""; private string strValidationGroup = ""; public string ValidationGroup { get { return strValidationGroup; } set { strValidationGroup = value; } } public string InvalidMessage { get { return strInvalidMessage; } set { strInvalidMessage = value; } } protected override void OnInit(EventArgs e) { rfv = new RequiredFieldValidator(); rfv.ControlToValidate = this.ID; rfv.ErrorMessage = "&lt;span style=\"color:black\"&gt;&lt;b&gt;Required Field Missing&lt;/b&gt;&lt;br /&gt;" + this.InvalidMessage + "&lt;/span&gt;"; //rfv.ErrorMessage = this.InvalidMessage; rfv.ID = "rfv" + this.ID; rfv.Display = ValidatorDisplay.None; rfv.SetFocusOnError = true; rfv.EnableClientScript = true; rfv.ValidationGroup = this.ValidationGroup; vce = new AjaxControlToolkit.ValidatorCalloutExtender(); vce.ID = "vce" + this.ID; vce.TargetControlID = "rfv" + this.ID; vce.Width = 300; ftb = new FilteredTextBoxExtender(); ftb.ID = "ftb" + this.ID; ftb.TargetControlID = this.ID; ftb.FilterType = FilterTypes.Numbers; Controls.Add(rfv); Controls.Add(vce); Controls.Add(ftb); } protected override void Render(HtmlTextWriter w) { //w.Write(this.InvalidMessage); base.Render(w); rfv.RenderControl(w); vce.RenderControl(w); ftb.RenderControl(w); } } } </code></pre> <p>my web.config entry looks like this (in the pages/controls area)</p> <pre><code>&lt;add tagPrefix="DTF" namespace="DTF.Web.UI" /&gt; </code></pre> <p>I've tried everything I can think of to get this to work and compile. The intellisense for the custom server controls works fine, it simply won't compile.</p> <blockquote> <p>I also get the error "The base class includes the field 'blanro', but its type (DTF.DateBoxFull) is not compatible with the type of control (DTF.DateBoxFull)."</p> </blockquote> <p>Any idea how to fix this, and why it would work in the regular asp.net website but not in a web project?</p> <p>Thanks Everyone.</p>

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).
