Advantage of repeater control over grid view in asp.net C#

asp.netgridviewrepeater

I have read many articles regarding difference between gridview and repeater. I come to know that gridview pattern is fixed in and , where as repeater can provide customized HTML mark up. If I am not wrong, we can also customize HTML mark up by adding template field and placing table with customized design. In that tables we can place labels and other .net control and can get whatever we want. Then why to use repeater control.

I am confused in which scenario it can be preferred over gridview.

In simple words we can say performance of repeater is far better than gridview. If you need basic rendering for read only items then its better to use repeater and if you need events , pagination and editable controls then you should go for gridview. Simpler controls with less in built functionality are speedy. you can do implement all functionalities of grid view to repeater but you have to do it manually.

So it depends upon you requirements either you need repeater or gridview

Programmatically accessing Data in an ASP.NET 2.0 Repeater

Off the top of my head, you can try something like this:

<ItemTemplate>
  <tr>
    <td "class1"><asp:Literal ID="litField1" runat="server" Text='<%# Bind("Field1") %>'/></td>
    <td "class1"><asp:Literal ID="litField2" runat="server" Text='<%# Bind("Field2") %>'/></td>
    <td "class1"><asp:Literal ID="litField3" runat="server" Text='<%# Bind("Field3") %>'/></td>
    <td "class1"><asp:Literal ID="litField4" runat="server" Text='<%# Bind("Field4") %>'/></td>
  </tr>
</ItemTemplate>

Then, in your code behind, you can access each Literal control as follows:

foreach (RepeaterItem item in rptrFollowupSummary.Items)
{   
    Literal lit1 = (Literal)item.FindControl("litField1");
    string value1 = lit1.Text;
    Literal lit4 = (Literal)item.FindControl("litField4");
    string value4 = lit4.Text;
}

This will add to your ViewState but it makes it easy to find your controls.

R – ASP.Net Repeater control

Try something like this in the code behind

  protected void rpt_OnItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if (e.Item.DataItem != null)
        {
            string color = (string)DataBinder.Eval(e.Item.DataItem, "RowColor");
            HtmlTableRow rowToColor = (HtmlTableRow)e.Item.FindControl("Row");
            rowToColor.Attributes.CssStyle.Add("background-color", color );
        }
    }

and something like this in the aspx page

<asp:Repeater ID="rpt" runat="server" OnItemDataBound="rpt_OnItemDataBound">
    <ItemTemplate>
        <tr id="Row" runat="server">
            <td>
            &nbsp;
            </td>
        </tr>
    </ItemTemplate>
</asp:Repeater>
