    copied!<p>Here's the scenario:</p> <p>I have a repeater inside an UpdatePanel called updPanel.</p> <p>Inside this repeater I have two Buttons, which fire an ItemCommand.</p> <p>In the page load I have this method:</p> <pre><code>if (!IsPostBack) { Bind(); } </code></pre> <p>Then, on Bind():</p> <pre><code>public void Bind() { rptList.DataSource = Model.GetData(Version); rptList.DataBind(); } </code></pre> <p>Then, on ItemCommand event:</p> <pre><code>public void rptList_ItemCommand(object source, RepeaterCommandEventArgs e) { //Some code to get info about the DataItems if (e.CommandName.Equals("MyCommandName1")) { //Do Stuff } else if (e.CommandName.Equals("MyCommandName2")) { //Do Other Stuff } Bind(); } </code></pre> <p>I have a button (inside the same update panel, but outside the repeater) which does nothing but Bind().</p> <p>When I click an ItemCommand, the command executes, but the screen is not updated (One of the item buttons should change its icon after clicking). If I refresh the page, or click the "Bind" button, the repeater shows the data as expected.</p> <p>Why isn't it binding after ItemCommand?</p> <p>Thanks in advance!</p> <p>EDIT: My Repeater:</p> <pre><code>&lt;asp:Repeater ID="rptList" runat="server"&gt; &lt;HeaderTemplate&gt; &lt;h3&gt; &lt;b class="rollback"&gt;Rollback&lt;/b&gt; | &lt;b class="emteste"&gt;Em Teste&lt;/b&gt; | &lt;b class="aindanaoincluido"&gt; Ainda não Incluído&lt;/b&gt; | &lt;b class="parcialmenteok"&gt;Atividade Parcialmente OK&lt;/b&gt; | &lt;b class="todosok"&gt;Atividade OK em Todas as Lojas&lt;/b&gt; | &lt;b class="publicado"&gt;Atividade Publicada&lt;/b&gt; &lt;/h3&gt; &lt;/HeaderTemplate&gt; &lt;ItemTemplate&gt; &lt;div class="item" style="display: inline-block"&gt; &lt;p style="font-size: 12px"&gt; &lt;asp:ImageButton ToolTip="Marcar como Rollback" ImageUrl="/_layouts/Extensions/Versioning/img/rollback.png" CommandName="MarkAsRollback" ID="btnItemRollback" CssClass="itembutton" runat="server" /&gt; &lt;asp:ImageButton ToolTip="Esta atividade possui código. Clique para sinalizar como apenas procedure/config" ImageUrl="/_layouts/Extensions/Versioning/img/code.png" CommandName="MarkAsProc" ID="btnItemProc" CssClass="itembutton" runat="server" /&gt; &lt;asp:Image ToolTip="Esta atividade não possui scripts de banco/zips." ImageUrl="/_layouts/Extensions/Versioning/img/noscript.png" runat="server" CssClass="itembutton" ID="btnItemScript" /&gt; &lt;asp:Label ID="labelWI" Text="" runat="server"&gt;&lt;/asp:Label&gt; &lt;span style="color: #4A82CB"&gt; &lt;%# DataBinder.Eval(Container.DataItem, "SystemAssignedTo") %&gt; - &lt;/span&gt;&lt;span style="color: Navy"&gt; &lt;%# DataBinder.Eval(Container.DataItem, "SystemTitle") %&gt; &lt;/span&gt; &lt;asp:HiddenField ID="workItemID" runat="server" /&gt; &lt;/p&gt; &lt;/div&gt; &lt;hr class="item" noshade style="color: #4CBDCB; height: 2px; background-color: #4CBDCB" /&gt; &lt;/ItemTemplate&gt; &lt;/asp:Repeater&gt; </code></pre> <p><strong>EDIT:</strong> To simplify, this is the behavior i'm getting:</p> <p>Clicking on a button outside the repeater: <strong>Icon changes. DB Updates.</strong></p> <p>Clicking on a button inside an item in the repeater: <strong>Icon doesn't change. DB Updates.</strong></p> <p>Clicking again on a button inside an item in the repeater: <strong>Icon changes. DB Updates. But now the corresponding item is wrong because I already changed the flag again</strong></p> <p>It seems to have to do with the order in which things happen.</p> <p><strong>EDIT:</strong> I forgot to mention, I tested with a full postback and everything works ok.</p>
