I declaratively added an SQL datasource. Then a Text Box and a button. When I configured the datasource and my query I added a select all field statement with the following WHERE clause: CONTAINS([ItemName], @ItemName) VALUE  SearchTxtBox.TEXT. I did this through the wizard not through code.  I then tested the query. I got the following error:

There was an Error Executing the Query

Cannot use a CONTAINS or FREETEXT predicate on a table or indexed view 'DataTable' because it is not full-text indexed.

 

1. How do I fully text index that table?

2. Or is there a better, or easier way to accomplish what I am trying to do?

 

What I want is just a simple Text box that an end user can put an item name in and then a detailsview get rendered with the result(s).

Also being that I am new at all this. I could also use some help with the event handler to submit the string from the text box for the query in C#.

 

Thank you in advance.

Well,

I actually figured this one out. I don't know exactly how. I thought I would post what I did so others could benefit from what I stumbled on.  I dragged a SQL datasource, a text box, a button, and a details views onto a page.  I configed the datasource. After poiting it to my DB and table, I specified a SELECT query  against a form control. That control was my text box.  The problem was I kept getting a error that there was no definition for the sqldatasource1_Select event.  I guess it automatcally coded this in from the Select statement I specified in the wizard.  I went into the source and deleted it. I also changed the select statement  from CONTAINS to LIKE. So then I viewed the page in the browser to see if the error went away. It did, the page loaded find.  Then just for giggles, I entered a string in the text box and clicked the button. WahLAh.....it submitted the query and the results were displayed in the details view.  What I do not under stand is that I did not add an event handler to handle the SearchButton_Click event, but it still submitted the query. I event went to the code behind to make sure, and there is no event handler. How did it know to do this?  Am I carzy?  I am suprised it worked. Can anyone tell me why?

Hi ,

As you point out your SELECT statement query against some text box placed on your page. This works because of that your SEARCH button rise a post back event. Rising this event trigger the SQLDATASOURCE control which is a server control, and at this moment the SELECT query is getting execute.

I guess this clear enough budy.

About the question how to fully text index a table, reference to this help:
