How to build a GridView like DataBound Templated Custom ASP.NET Server Control
- by Deyan
I am trying to develop a very simple templated custom server control that resembles GridView. Basically, I want the control to be added in the .aspx page like this:
<cc:SimpleGrid ID="SimpleGrid1" runat="server">
<TemplatedColumn>ID: <%# Eval("ID") %></ TemplatedColumn>
<TemplatedColumn>Name: <%# Eval("Name") %></ TemplatedColumn>
<TemplatedColumn>Age: <%# Eval("Age") %></ TemplatedColumn>
</cc:SimpleGrid>
and when providing the following datasource:
DataTable table = new DataTable();
table.Columns.Add("ID", typeof(int));
table.Columns.Add("Name", typeof(string));
table.Columns.Add("Age", typeof(int));
table.Rows.Add(1, "Bob", 35);
table.Rows.Add(2, "Sam", 44);
table.Rows.Add(3, "Ann", 26);
SimpleGrid1.DataSource = table;
SimpleGrid1.DataBind();
the result should be a HTML table like this one.
-------------------------------
| ID: 1 | Name: Bob | Age: 35 |
-------------------------------
| ID: 2 | Name: Sam | Age: 44 |
-------------------------------
| ID: 3 | Name: Ann | Age: 26 |
-------------------------------
The main problem is that I cannot define the TemplatedColumn. When I tried to do it like this ...
private ITemplate _TemplatedColumn;
[PersistenceMode(PersistenceMode.InnerProperty)]
[TemplateContainer(typeof(TemplatedColumnItem))]
[TemplateInstance(TemplateInstance.Multiple)]
public ITemplate TemplatedColumn
{
get { return _TemplatedColumn; }
set { _TemplatedColumn = value; }
}
.. and subsequently instantiate the template in the CreateChildControls I got the following result which is not what I want:
-----------
| Age: 35 |
-----------
| Age: 44 |
-----------
| Age: 26 |
-----------
I know that what I want to achieve is pointless and that I can use DataGrid to achieve it, but I am giving this very simple example because if I know how to do this I would be able to develop the control that I need. Thank you.
