    <p>Please let me know if this works:</p> <pre><code>private void button7_Click(object sender, EventArgs e) { ProductDetails.Items.Clear(); SqlConnection con = new SqlConnection(@"server=xxx-PC; database= sample; integrated security= true"); SqlCommand cmd = new SqlCommand("select * from tblproduct where prodname like @name;", con); cmd.Parameters.AddWithValue(textBox1.Text.Trim() + "%"); SqlDataAdapter da = new SqlDataAdapter(cmd); DataTable dt = new DataTable(); try { con.Open(); da.Fill(dt); } catch (Exception e) { //exception handling here } finally { con.Close(); } foreach(DataRow dr in dt.Rows) { byte[]imgg =(byte[])dr["image"]; if(imgg==null || imgg.length &lt;= 0) pictureBox1.Image= null; else { pictureBox1.Image = ByteToImage(imgg); } ProductDetails.Items.Add(dr[0].ToString() + " \t" + dr[1].ToString() + "\t" + dr[2].ToString() + dr[3].ToString()); } } // https://stackoverflow.com/questions/9576868/how-to-put-image-in-a-picture-box-from-a-byte-in-c-sharp public static Bitmap ByteToImage(byte[] blob) { MemoryStream mStream = new MemoryStream(); byte[] pData = blob; mStream.Write(pData, 0, Convert.ToInt32(pData.Length)); Bitmap bm = new Bitmap(mStream, false); mStream.Dispose(); return bm; } </code></pre> <p>You can also use a <code>using</code> block with the <code>SqlConnection</code> as in <a href="https://stackoverflow.com/questions/4717789/in-a-using-block-is-a-sqlconnection-closed-on-return-or-exception">this SO question</a>. Also please note that it is better to <strong>not</strong> use <code>Select * from ...</code> but name the columns.

    2. CO@pooja You're not being specific enough to allow people to help you. You've been asked twice now, "Which line does the error occur on?", and you still haven't given an answer. So, please edit your question to include both the exact line which is causing the error and also **the exact error message** you are getting.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
