I have a search textbox to search songs and a search button in my form on button click it returns searched results and binds to repeater control.

But the problem is that if first time i search for any song then it is showing and binding to repeater control but when i click on search button when textbox is blank then it binding the last searched result. and Label control showing No result found(i'm using label control to show result count and if repeater1.items.count is 0 then it is showing No result found)

C#

SqlConnection sqlconn = new SqlConnection("server=.\\sqlexpress;database=Musicmania;integrated security=true;");
SqlCommand sqlcomm = new SqlCommand("select  * from uploadmp3 where song_name='" + txtSearch.Text + "'", sqlconn);
        sqlconn.Open();
        SqlDataReader dr = sqlcomm.ExecuteReader();
       
        if (dr.HasRows)
        {
            Repeater2.DataSource = dr;
            Repeater2.DataBind();
            Label1.Text = Repeater2.Items.Count + " Result(s) Found";

           Repeater2.Visible = true;
            
            linkNext.Visible = false;
            linkPrev.Visible = false;
            Label1.Visible = true;
            dr.Close();
            sqlconn.Close();
        }
        else
        {
            linkNext.Visible = false;
            linkPrev.Visible = false;
            Label1.Text = "No Result Found";
            

        }

You are binding Repeater when data is present. But when data is not present you are not binding Repeater , So what you looking is previous data because your repeater not bind again.
Either you should hide repeater or bind Repeater in both cases.

if (dr.HasRows)
 {
Repeater2.Visible = true;
}
else
{
Repeater2.Visible = false;
}

You should validate your textbox to avoid error.

C#

if(txtSearch.Text.Trim() != "")
{
Label1.Text = "Please insert song name.";
}

Use stored procedure rather than inline query.

Solution 2

JavaScript

<script type="text/javascript">
function mySubmit()
{
if(document.getElementById('txtSearch').value == '')
{
return false;
}
}</script>

C#

On page Load
{
ImageButton1.Attributes.Add("onclick", "javascript:return mySubmit()");

}
