    text
    copied!<p>Thanks in advance for your help.</p> <p>I am using c#.net.</p> <p>I have two views on my webpage (contained within one multiview), both contain buttons. </p> <p>view_1 </p> <p>Contains a repeater/datasource and an custom made ‘edit’ button (which holds the ID for each row returned).</p> <p>view_2</p> <p>Contain an ‘update’ form and a ‘update’ button. When the user presses the update button the information within the database for that particular row is updated.</p> <p>The problem I believe lies with my ‘update’ button within view_2 </p> <p>Code behind (‘update’ button), I have an if statement:</p> <pre><code> protected void Page_Load(object sender, EventArgs e) { updateSuccessFailed.Visible = false; if (!Page.IsPostBack) { _multiView1.ActiveViewIndex = 0; } } protected void update_Click(object sender, EventArgs e) </code></pre> <p>{</p> <pre><code> var Id = Convert.ToInt32((ID.Value)); notYetUpdated.Visible = true; updateSuccessFailed.Visible = false; tblV updateV = new tblV(); updateV.vID = venueId; updateV.vame = updateName.ToString(); updateV.vPostcode = updatePropPostcode.ToString(); if (vRepos.Update(updateV)) { notYetUpdated.Visible = false; updateSuccessFailed.Visible = true; updateMessage.Text = "Updated."; } else { notYetUpdated.Visible = false; updateSuccessFailed.Visible = true; updateMessage.Text = "An error has occurred, please try again."; } } </code></pre> <p>_view2</p> <pre><code>&lt;asp:View ID="_view2" runat="server"&gt; &lt;div style="text-align:center" runat="server" id="notYetUpdated"&gt; &lt;table border="0" cellspacing="1"&gt; &lt;tr&gt; &lt;td style="text-align:left;"&gt;Name&lt;/td&gt; &lt;td style="text-align:left;"&gt;&lt;asp:TextBox ID="updateName" MaxLength="60" runat="server" /&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td style="text-align:left;"&gt;Postcode&lt;/td&gt; &lt;td style="text-align:left;"&gt;&lt;asp:TextBox ID="updatePropPostcode" MaxLength="60" runat="server" /&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;&lt;br /&gt; &lt;asp:Button ID="updateVCancel" Text="Cancel" runat="server" onclick="cancel_Click" CssClass="standardButton" /&gt; &lt;asp:Button ID="updateVConfirm" Text="Update" runat="server" onclick="update_Click" CssClass="standardButton" /&gt; &lt;asp:HiddenField ID="vUpdateID" runat="server" /&gt; &lt;/div&gt; &lt;div style="text-align:center" runat="server" id="updateSuccessFailed"&gt; &lt;p&gt;&lt;asp:Label ID="updateMessage" runat="server" /&gt;&lt;/p&gt; &lt;asp:Button ID="updateBack" Text="Back To Start" runat="server" onclick="backToStart_Click" CssClass="standardButton" /&gt; &lt;/div&gt; &lt;/asp:View&gt; </code></pre> <p>notYetUpdated / updateSuccessFailed are div’s which hold different information. </p> <p>When the user first ‘updates’ a record it make the right div visible. (notYetUpdated – holds the form information / updateSuccessFailed – holds a message to state whether the record has been updated or not). However when you access the view_2 again it accesses the update_Click event and updateSuccessFailed is visible even though it shouldn’t be.</p> <p>I thought I could clear all stored information within the viewstates with the code below, however this is not working.</p> <pre><code> ViewState.Clear(); ClearChildViewState(); </code></pre> <p>Thanks </p> <p>Clare :-)</p>
