    <p>I have a ascx page where I am using a hidden field to store the value of a the drop down box as it is generated using a google address finder. My problem is that when I try to store the value directly in the hidden field:</p> <pre><code>hfDdlVerifyID.Value = ddlVerifySS.SelectedValue; </code></pre> <p>in the event of a button click, the value is stored but on postback is lost again. Whereas, if i try to use Scriptmanager to do it, nothing is stored.</p> <pre><code>getBuild.AppendLine("$get('" + hfDdlVerifyID.ClientID + "').value = $get('" + ddlVerifySS.ClientID + ").value;"); ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "storeHidden", getBuild.ToString(), true); // Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "storeHidden", getBuild.ToString(), true); string test = hfDdlVerifyID.Value.ToString(); </code></pre> <p>The ascx page is :</p> <pre><code>&lt;asp:UpdatePanel ID = ddlUpdate runat="server"&gt; &lt;ContentTemplate&gt; &lt;asp:Panel ID="pVerify" runat="server"&gt; &lt;br /&gt; &lt;fieldset&gt; &lt;legend&gt; &lt;asp:Literal ID="lVerify" runat="server" /&gt; &lt;/legend&gt; &lt;asp:CheckBox ID ="cbVerify" runat ="server" Text ="Use the value from the following list, (Uncheck to accept address as it is)." Checked ="true" /&gt; &lt;br /&gt; &lt;asp:DropDownList ID="ddlVerifySS" runat="server" onselectedindexchanged="ddlVerifySS_SelectIndexChange" /&gt; &lt;asp:HiddenField id="hfDdlVerifyID" runat ="server" /&gt; &lt;/fieldset&gt; &lt;/asp:Panel&gt; &lt;/ContentTemplate&gt; &lt;/asp:UpdatePanel&gt; &lt;padrap:Button ID ="bVerify" runat ="server" CssClass ="btn" OnClick ="bVerify_Click" Text ="Verify Address" /&gt; &lt;asp:Button ID ="btnSubSite" runat ="server" text ="Save" CssCLass ="btn" OnClick ="save_btn_Click_subSite" onLoad="ddlVerify_Load" /&gt; </code></pre>

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.
