View 1 RepliesForms Data Controls :: Conversion From Type 'TextBox' To Type 'String' Is Not Valid?
Sep 6, 2010I have a FormView that allows a user to register for a company event. I want to do a couple of things with this form.
1. I need to write this data to a MS SQL database
2. I need to send an email confirmation of their registration to their email.
I know how to do both of these things, but i am having trouble doing both at the same time.
It would be nice if I could do it in one click, but I coded it into two pages to try to help simplify it.
The first page allows the user to input their information into a formview and when they click the submit button, it places those answers into session variables:
[Code]....
[Code]....
The Second page confirms the users information by taking those session variables and placing them into labels:
[Code]....
[Code]....
However, after I place information into the formview on the first page, it throws up this error:
"Conversion from type 'TextBox' to type 'String' is not valid".

Forms Data Controls :: How To Implement A Filter Feature With Dynamic Chained Dropdown List
Jan 15, 2011how to implement a filter feature like this? What Ajax or JQuery controls can be used for this (if any)?
Here is an example of how the UI might look like:
See the Exchange Management Console image:
[URL]
Here is the spec:
The ASP.NET page has a "Filter" component and a "Apply Filter" button. The "Filter" component consists of 4 UI controls as below:
1. A dropdown list with prepopulated values like "Name", "Department", "Building", "Email Address".
2. A dropdown list with four operators - "Equal", "Not Equal", "Like", and "Not Like"
3. This is a dynamic control. It could be a textbox or a dropdown list. If the user chooses "Name" from the first UI control, the third UI control will become a Textbox. If the user chooses "Department" from the first UI control, the third UI control will become a dropdown list with all departments within this company pre-populated.
4. A button with AND expression. If the user clicks this button, one more Filter component will be created.
One possible user case is like this:
ASP.NET: when the page is loaded, it displays one Filter component (3 UI controls and a AND button), a "Apply Filter" button, and an empty "Filter Result" data grid.

Visual Studio 2010 - Dynamic Data TextSearch Custom Filter Template
Aug 31, 2010I'm trying to implement a custom filter template for all text based searches and running into problems constructing the query. I've been following the instructions posted on this blog but not sure how change the GetQueryable method to perform a WHERE columnAttribute LIKE '%something%'query. In the example on the blog the expression is an equality which works if the text I enter exactly matches the text in the database column.
At the moment I'm using the new QueryExtender feature along with the SearchExpression control but this requires creating several custom pages for all the tables I need text search functionality for. I would like to DRY this up by creating the custom filter template.
