Question

User-569896929 posted

Hi

I have database of users,items and bookmarks tables.

When user bookmarks an item it stores user id and item id into bookmarks table

I have a repeater that shows many items list using data binding and it have an bookmark button on it.

If the item is already bookmarked by logged in user it should be of green color else red color.

How can i achieve this using repeater control.

Hi,

If you maintain user in the bookmarks table, then in databound event of repeater, check whether the logged in user is already bookmarked the corresponding item are not.

Hi Nithin,

Thanks for your post.

If the item is already bookmarked by logged in user it should be of green color else red color.

You could dynamically set item’s background color in Repeater ItemDataBound Event, You code may look like this.

<ItemTemplate>
    <tr runat="server" id="itemrow">
        <td>
            <asp:Label runat="server" ID="lblId" Text='<%# Eval("Id") %>' />
        </td>
        <td>
            <asp:Label runat="server" ID="lblItemId" Text='<%# Eval("ItemId") %>' />
        </td>
        <td>
            <asp:Label runat="server" ID="lblUserId" Text='<%# Eval("UserId") %>' />
        </td>
    </tr>
</ItemTemplate> 

protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
    if (e.Item.ItemType== ListItemType.Item)
    {
        string uid = ((Label)e.Item.FindControl("lblUserId")).Text.ToString();

        if (uid == loginuid)
        {
            ((HtmlTableRow)e.Item.FindControl("itemrow")).BgColor = "green";
        }
        else
        {
            ((HtmlTableRow)e.Item.FindControl("itemrow")).BgColor = "red";
        }
    }
            
}
