Filtering based upon template field value

Hi,

I have the following setup.  An ObjectDataSource which is used to populate a Details view control.

This is current used for inserting data.  One of the fields iwithin this is a template field into which I have placed calendar extender control.

Here is what I want to achieve. Add a gridview control on to the same page that when the page loads shows all of records from the table.  I then wish this gridview to be filtered when a user makes a selection from the date templatefield.

Thinking about this I need to first capture the event of adding a date.  I take it this will be on change event of the textbox rather then onClick of the calendar extender control.  Not sure how to access template field controls inside a details view?

Next I need some way of filter the ObjectDataSource of the new gridview.  I have setup a query that accepts a parameter but normally I can specify to take the parameter from a control, but in this case I won’t be able to because it’s inside a details view control.

Any help much appreciated.

Not getting the scenario you are trying to use these controls. Generally you use GV->Detailsview but here you are trying to use DV->GV.

You can find the control in DetailsViews like you would normally do.
e.g
TextBox tb = (TextBox )DetailsView1.FindControl("txtDate");

For setting the parameter value programmatically check this:

Thanks, I still can't see how to do something on the event of a template field?

Your code allows me to find a control, great if I want to change it's attribute, but how for example could I access the onchange event?

Thanks again.

Where is your TB, inside GV? If you want to filter data, you can put that filter outside of GV.
