Hi Tomasz,
This is really an interesting question. I understand that your objective
here is to programmatically create an ObjectDataSource instance at run-time
and want to bind your GridView to it. So far you're seeing that the data
displays but editing it will require you manually handle the OnRowEditing
event.
With Reflector (
http://www.aisto.com/roeder/dotnet/), you could see that
GridView.OnRowEditing will throw the exception if the DataSourceID property
is not set.
To workaround this limit, I'm afraid you will have to associate the
ObjectDataSource with the GridView using DataSourceID property instead of
DataSource. To do that, we will also have to add the ObjectDataSource to
the same container of GridView:
<%@ Page Language="C#" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
ObjectDataSource ods = new
ObjectDataSource("DataSet1TableAdapters.Categories TableAdapter", "GetData");
ods.OldValuesParameterFormatString = "Original_{0}";
ods.UpdateMethod = "Update";
ods.UpdateParameters.Add("CategoryName", TypeCode.String, null);
ods.UpdateParameters.Add("Original_CategoryID", TypeCode.Int32,
null);
ods.ID = "ods1";
form1.Controls.Add(ods);
GridView1.DataSourceID = ods.ID;
}
</script>
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:GridView ID="GridView1" runat="server" AllowPaging="True"
AllowSorting="True"
AutoGenerateColumns="False" DataKeyNames="CategoryID">
<Columns>
<asp:CommandField ShowEditButton="True" />
<asp:BoundField DataField="CategoryID"
HeaderText="CategoryID" InsertVisible="False"
ReadOnly="True" SortExpression="CategoryID" />
<asp:BoundField DataField="CategoryName"
HeaderText="CategoryName" SortExpression="CategoryName" />
</Columns>
</asp:GridView>
</div>
</form>
</body>
</html>
Hope this helps.
