Pass parameter as

C#

SqlConnection conn = new SqlConnection(strcon);
conn.Open(); // open the connection
SqlCommand cmd=new SqlCommand("select Image, ImageName from Img where ([Date] = @date) ", conn);
cmd.Parameters.AddWithValue("date",datevalue);
SqlDataAdapter Sqa = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
Sqa.Fill(ds); // fill the dataset
GridView1.DataSource = ds; // give data to GridView
GridView1.DataBind();
conn.Close();

datevalue will be value of date that you want to pass in query

Hi,
You can use AddWithValue to supply the @date parameter's value:
Sqa.SelectCommand.Parameters.AddWithValue("@date", YourDateParameter);

declare date globally,so that u can access it through out the code page.
yyyy-mm-dd is universal date format.

Problem is u didn't pass any input to that query and another problem is if u r saving the date with time then '=' doesn't give results so I made that conversion and it will get the results on that date.
I've converted to 101 as ur cilture is en-US
for en-IN u can convert to 105

change the line as:
SqlDataAdapter Sqa = new SqlDataAdapter(string.Format("select Image, ImageName from Img where (convert(varchar(20),[Date],101) = '{0}') ",date.ToShortDateString()), conn);

Hope it works.
