ASP.NET (C#) Question

Updating my Gridview Search boxes to use LIKE instead of '= or null'

I currently have a gridview that has text boxes across the top that the user can leave blank (in which case all records in the table are returned) or the user can supply exact matches to information in corresponding fields in the table in the text boxes which will restrict results to only those records have those rows that have the contents of the text box in the corresponding field. I have 14 of these text boxes and any combination of them can be populated or left unused creating a filter for the records a user desires.

But I would like to take this to the next step. Instead of requiring an 'exact match' I would prefer to do a LIKE. Essentially if I supply the word dog I would like the select to effectively function as %dog%. I've try several different ways to approach this but I can't seem to get anything to work. So I thought that I would put out my code here and a screen shot of what I have and see if anyone has any suggestions of how to go about accomplishing this.

My aspx Page looks like this:

Hoping someone has some insight because I would love to be able to implement a LIKE to these text boxes.

Answer

You will need IS NULL OR LIKE in where clause.

SelectCommand="SELECT AssetID, ..., AssetOperStatus 
FROM cmdbv_Assets_CInTrac 
WHERE (@AssetID IS NULL OR AssetID LIKE '%' + @AssetID + '%') AND 
...
(@AssetStatus IS NULL OR AssetStatus LIKE '%' + @AssetStatus + '%')"
