Question

Here’s the scenario:

I have a repeater inside an UpdatePanel called updPanel.

Inside this repeater I have two Buttons, which fire an ItemCommand.

In the page load I have this method:

if (!IsPostBack)
{               
    Bind();
}

Then, on Bind():

public void Bind()
{
    rptList.DataSource = Model.GetData(Version);
    rptList.DataBind();
}

Then, on ItemCommand event:

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();
}

I have a button (inside the same update panel, but outside the repeater) which does nothing but Bind().

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.

Why isn’t it binding after ItemCommand?

Thanks in advance!

EDIT: My Repeater:

<asp:Repeater ID="rptList" runat="server">
    <HeaderTemplate>
        <h3>
            <b class="rollback">Rollback</b> | <b class="emteste">Em Teste</b> | <b class="aindanaoincluido">

        </h3>
    </HeaderTemplate>
    <ItemTemplate>
        <div class="item" style="display: inline-block">
            <p style="font-size: 12px">
                <asp:ImageButton ToolTip="Marcar como Rollback" ImageUrl="/_layouts/Extensions/Versioning/img/rollback.png"
                                CommandName="MarkAsRollback" ID="btnItemRollback" CssClass="itembutton" runat="server" />
                <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" />
                 <asp:Image ToolTip="Esta atividade não possui scripts de banco/zips." ImageUrl="/_layouts/Extensions/Versioning/img/noscript.png"
                                runat="server" CssClass="itembutton" ID="btnItemScript" />
                 <asp:Label ID="labelWI" Text="" runat="server"></asp:Label>
                 <span style="color: #4A82CB">
                                <%# DataBinder.Eval(Container.DataItem, "SystemAssignedTo") %>
                                - </span><span style="color: Navy">
                                    <%# DataBinder.Eval(Container.DataItem, "SystemTitle") %>
                                </span>
                 <asp:HiddenField ID="workItemID" runat="server" />
              </p>
         </div>
         <hr class="item" noshade style="color: #4CBDCB; height: 2px; background-color: #4CBDCB" />
     </ItemTemplate>
</asp:Repeater>

EDIT: To simplify, this is the behavior i’m getting:

Clicking on a button outside the repeater: Icon changes. DB Updates.

Clicking on a button inside an item in the repeater: Icon doesn’t change. DB Updates.

Clicking again on a button inside an item in the repeater: Icon changes. DB Updates. But now the corresponding item is wrong because I already changed the flag again

It seems to have to do with the order in which things happen.

EDIT: I forgot to mention, I tested with a full postback and everything works ok.

Answer 1

When are you loading myDataSource?

If you’re loading data into it in Page_Load, which is executed before rptList_ItemCommand, then bind() would be binding an old set of data to the repeater. This would explain your third summary point:

Clicking again on a button inside an item in the repeater: Icon changes. DB Updates. But now the corresponding item is wrong because I already changed the flag again

Can you give us more details about your datasource and the event handler for the button outside the repeater?
