I have just simulated your problem in my Dynamic Data project. Based on my research (and search) in order to get control value (not from DynamicControl
value) in Dynamic Data you should implement the following method (i am using this method in my project and i have found one on Steve blog, i don't remember full link):
/// <summary>
/// Get the control by searching recursively for it.
/// </summary>
/// <param name="Root">The control to start the search at.</param>
/// <param name="Id">The ID of the control to find</param>
/// <returns>The control the was found or NULL if not found</returns>
public static Control FindControlRecursive(this Control Root, string Id)
{
if (Root.ClientID.IndexOf(Id) > 0)
return Root;
foreach (Control Ctl in Root.Controls)
{
Control FoundCtl = FindControlRecursive(Ctl, Id);
if (FoundCtl != null)
return FoundCtl;
}
return null;
}
Now, my EXAMPLE.
First, my custom Insert.aspx
page with FormView and EntityDataSource:
<asp:FormView runat="server" ID="FormView1" DataSourceID="DetailsDataSource" DefaultMode="Insert"
OnItemCommand="FormView1_ItemCommand" RenderOuterTable="false">
<InsertItemTemplate>
<table>
<tr valign="top">
<td colspan="3">
<asp:TextBox ID="txtTitle" Width="99%" Visible="true" runat="server" /><br />
<br />
</td>
</tr>
</table>
</InsertItemTemplate>
</asp:FormView>
<asp:EntityDataSource ID="DetailsDataSource" runat="server" EnableInsert="true" OnInserted="DetailsDataSource_Inserted" />
Then, Inserted event of EntityDataSource:
protected MetaTable table;
protected void DetailsDataSource_Inserted(object sender, EntityDataSourceChangedEventArgs e)
{
if (e.Exception == null || e.ExceptionHandled)
{
string strTitle = String.Empty;
Control CtlTitle = FormView1.FindControlRecursive("txtTitle");
if (CtlTitle != null)
{
TextBox TextBoxTitle = (TextBox)CtlTitle;
strTitle = TextBoxTitle.Text;
}
Response.Redirect(table.ListActionPath + "?" + "Department_Id=" + strTitle);
}
}
Finally, i enter the text into txtTitle
, for example, 13 and then i get
