    <p>I'm using a detailsview for a dialog to the user, and it seems that the viewstate is not preserved when there is an error inserting the data.</p> <p>I'm using a OnInserted handler on the datasource to check if there was an exception like so:</p> <pre><code>protected void areaInsertHandler(Object sender, SqlDataSourceStatusEventArgs e) { if (e.Exception != null) { // There was an error in submitting, show the error dialog ScriptManager.RegisterClientScriptBlock(Page, GetType(), "DialogHandler", "showError('#overlayAreas');", true); e.ExceptionHandled = true; } } </code></pre> <p>Which simply calls the client side JS function:</p> <pre><code>function showError(overlayName) { $(".msgError").css('visibility', 'visible'); $(overlayName).css('visibility', 'visible'); } </code></pre> <p>My detailsview looks something like this:</p> <pre><code>&lt;asp:UpdatePanel ID="AreaUP" runat="server" UpdateMode="Conditional"&gt; &lt;ContentTemplate&gt; &lt;div id="overlayAreas" class="overlay"&gt; &lt;asp:DetailsView ID="DetailsView_Areas" runat="server" Visible="True" AutoGenerateInsertButton="False" AutoGenerateRows="False" caption="&lt;a style='font-weight: bold;'&gt;Bold&lt;/a&gt; = Required field" CaptionAlign="Bottom" headertext="Create new area" EnableViewState="true" DataKeyNames="Area_Name" DataSourceID="AreasSource" DefaultMode="Insert"&gt; &lt;Fields&gt; ... &lt;/Fields&gt; &lt;/asp:DetailsView&gt; &lt;/div&gt; &lt;br /&gt; &lt;asp:Button width="200" height="30" ID="Button_CreateArea" runat="server" OnClientClick="return btnToggle('#overlayAreas')" Text="Create new area" /&gt; &lt;/ContentTemplate&gt; &lt;/asp:UpdatePanel&gt; </code></pre> <p>It all works fine, but for some reason the ASP viewstate is not preserved. Meaning that if I fill out incorrect information in the form and submit I will get the appropriate error and the dialog will still be displayed. But the fields are not filled out with my old values.</p> <p>If someone could give me some pointers or help me out I'd greatly appreciate it</p> <p>EDIT 10-08: Still haven't been able to solve it, any ideas at all?</p>

    1. COCould it be that you are using and older version of the ASP.NET framework where the enableviewstate cannot be overriden in the controls on the page if it is set in the page,usercontrol and masterpage declaration?

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.

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