I guess, Repeater control seems to be appropriate comparing to
PlaceHolder control. Because, you can very easily iterate thru the Data.
Lets see how it is easy. For example, I have the following aspx code
<asp:Repeater Id="repeater1" runat="server">
<ItemTemplate>
<asp:CheckBox Id="checkBox1" runat="server"></asp:CheckBox>
<asp:Image Id="image1" runat="server" />
</ItemTemplate>
</asp:Repeater>
Now, In the Page_Load Event I am binding the data to this control.
if (!IsPostBack)
{
//table is a DataTable object which the data needed to be populated
repeater1.DataSource = table;
repeater1.DataBind();
}
Once the data is binded, ASP.NET will call ItemDataBound event while
binding the data to the repeater control. I guess, you know how to
create ItemDataBound event for the repeater control.
Inside the ItemDataBound event,
void repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
DataRow row = e.Item.DataItem as DataRow;
Image image1 = e.Item.FindControl("image1");
image1.ImageUrl = row["image"];
}
Now if you look at the code, you can easily understand how I am binding
the data to the Image control. This ItemDataBound will be called for
each and every row present in the table and binds the image column's
data to the ImageUrl property of image1 control.
Let me know in case you need further clarification.
