Using wildcards with a LinqDataSource

Question

I currently have a LinqDataSource on an ASP.NET page which is used as the data source for a FormView. I need to dynamically alter the where clause based on para

Answer 1

Please try url decode Request.QueryString[key]

Example:

HttpUtility.UrlDecode(Request.QueryString[key]);

Answer 2

I have finally managed to get this figured out. Thanks to a class from this post, I am able to to use the LinqDataSource_Selecting event and filter my data successfully with wildcards working using this code:

protected void ldsData_Selecting(object sender, LinqDataSourceSelectEventArgs e)
{
    var result = db.INSTRUMENT_LOOP_DESCRIPTIONs.AsQueryable();

    foreach (string key in Request.QueryString.Keys)
    {
        if (Request.QueryString[key].Trim() != "")
        {
            result = result.WhereLike(key, Request.QueryString[key].Replace("?", "_").Replace("*", "%"));
        }
    }

    e.Result = result;
}
