Plz help with DataItem ItemCreated event (databinding) 1

[LoveToCode]

Hello,

I have a very simple function that binds a dataset to a reapeater. I want to add a link programmaticaly, depending on a condition. Here is the function:

    private void LoadComments()
    {

        DataSet ds = thisUser.GetAllComments(thisUser.UserId);
        rp_Comments.DataSource = ds;
        rp_Comments.DataBind();
    }

I need to examine the dataset to see if a column called "UserID" equals some value then add link to that particular item.

Ive done some research and found that I can subscribe to an event like this:

        rp_Comments.ItemCreated += new RepeaterItemEventHandler(rp_Comments_ItemCreated);

But once i have the even handler, I dont know how to look at the dataset, and add the link:

    void rp_Comments_ItemCreated(object sender, RepeaterItemEventArgs e)
    {
       // What do I do now?!?! :O
    }

Thank you!

You'll want to use the ItemDataBound event of the repeater.

Also

void rp_Comments_ItemCreated(object sender, RepeaterItemEventArgs e)
{
// What do I do now?!?! :O
}

You have to give more details on what you want to do here.

I have a Repeater list control that I am binding to called "rp_comments". These are comments specific to a user. I need to provide a link that will appear if the user that posted the comment is the same user (same userId) viewing the comments. This link will allow that user to delete their comment.

Here is my ASPX code for the control:

    <asp:Repeater ID="rp_Comments" runat="server">
                <ItemTemplate>
                    <div class="comment">
                        <div>
                            <a href="<%=Core.Config.Root%>/profile/?userid=<%# DataBinder.Eval(Container.DataItem, "friendId") %>">
                                <img src="<%=Core.Config.Root%>/shared/WiseImage.ashx?height=100&Image=<%# DataBinder.Eval(Container.DataItem, "FriendId") %>.jpg"
                                    alt="<%# DataBinder.Eval(Container.DataItem, "Quote") %>"></a> <a href="/">
                                        <%# DataBinder.Eval(Container.DataItem, "Username") %>
                                    </a>
                        </div>
                        <p class="headline">
                            <%# Convert.ToDateTime(DataBinder.Eval(Container.DataItem, "DatePosted")).ToShortDateString() %>
                        </p>
                        <p>
                            <%# DataBinder.Eval(Container.DataItem, "Comment") %>]

          <!-- INSERT A DELETE LINK HERE
                IF THE USER VIEWING OWNS
               THIS COMMENT -->


                        </p>
                        <br class="clear">
                    </div>
                    <br class="clear">
                </ItemTemplate>
            </asp:Repeater>

I know there are several ways to insert a link; I could create a new hyperlink control, or simply write out an HTML anchor tag, or even assign a label or literal control that HTML. Whatever works is fine.

I added a comment in that code where I'd like the link to appear.

Thank you for your help!

Use the ItemDataBound event of the repeater, then something like:

If e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem Then
   Dim dr As DataRowView
   dr = DirectCast(e.Item.DataItem, DataRowView)
   If dr.Item("UserName") = "some check here" Then
      '... Add your hyperlink
   End If

i'd put in the hyperlink on the html side, set visible=false on it,

then use as jb is stating, but i'd do it like this...

( <asp:Repeater id=bla runat=server onItemDataBound=rp_IDB> )

    public void rp_IDB(object sender, RepeaterItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.SelectedItem)
        {
            ((HyperLink)(e.Item.FindControl("myHyperLinkIsHere"))).Visible = 
                YourLogicToGetCurrentUserID(Convert.ToInt32(DataBinder.Eval(e.Item.DataItem, "UserID")));
            //Boolean function that returns wether or not this guy logged in started it
        }
    }

Cool, this works great. Thanks for the excellent example!
