What have you tried?

Pawan Wagh 4-Apr-14 15:18pm

i have tried something like this...
protected void Page_Load(object sender, EventArgs e)
{
string tooltip = string.Empty;
foreach (ListItem chk in CheckBoxList1.Items)
{
using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString))
{
using (SqlCommand cmd = new SqlCommand())
{
try
{
cmd.Connection = con;
cmd.CommandText = "SELECT * FROM Stud_Table WHERE Name='"+ chk.Text +"'";
con.Open();
SqlDataReader rd = cmd.ExecuteReader();
tooltip = rd[0].ToString() + Environment.NewLine + rd[1].ToString() + Environment.NewLine + rd[2].ToString();
}
catch (Exception ex)
{
string error_message = ex.Message;
Response.Write("<script LANGUAGE='JavaScript'>alert('" + error_message + "')</script>");
}
finally
{
con.Close();
}
}
}
chk.Attributes.Add("title", tooltip);
}
}

You have a tooltip variable defined? What have you tried to show that?

Pawan Wagh 4-Apr-14 15:52pm

the details of item in checkboxlist like name,date of birth,address

Okay, but what you tried to achieve that.

does your tooltip variable have a value in it if you debug it? Otherwise I would recommend putting the chk.Attributes.Add right after you set the value before you close the datareader connection. that might be tripping you up.

hey i have solved it and thanx 4 your help.....

protected void CheckBoxList1_DataBound(object sender, EventArgs e)
{
string tooltip = string.Empty;
foreach (ListItem chk in CheckBoxList1.Items)
{
using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString))
{
using (SqlCommand cmd = new SqlCommand())
{
try
{
cmd.Connection = con;
cmd.CommandText = "SELECT * FROM Stud_Table WHERE Name='" + chk.Text + "'";
con.Open();
SqlDataReader rd = cmd.ExecuteReader();
while(rd.Read())
tooltip = rd[0].ToString() + Environment.NewLine + rd[1].ToString() + Environment.NewLine + rd[2].ToString();
chk.Attributes.Add("title", tooltip);
}
catch (Exception ex)
{
string error_message = ex.Message;
Response.Write("<script LANGUAGE='JavaScript'>alert('" + error_message + "')</script>");
}
finally
{
con.Close();
}
}
}

}
}

OP has solved this himself.

C#

protected void CheckBoxList1_DataBound(object sender, EventArgs e)
{
    string tooltip = string.Empty;
    foreach (ListItem chk in CheckBoxList1.Items)
    {
        using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString))
        {
            using (SqlCommand cmd = new SqlCommand())
            {
                try
                {
                    cmd.Connection = con;
                    cmd.CommandText = "SELECT * FROM Stud_Table WHERE Name='" + chk.Text + "'";
                    con.Open();
                    SqlDataReader rd = cmd.ExecuteReader();
                    while(rd.Read())
                        tooltip = rd[0].ToString() + Environment.NewLine + rd[1].ToString() + Environment.NewLine + rd[2].ToString();
                    chk.Attributes.Add("title", tooltip);
                }
                catch (Exception ex)
                {
                    string error_message = ex.Message;
                    Response.Write("<script LANGUAGE='JavaScript'>alert('" + error_message + "')</script>");
                }
                finally
                {
                    con.Close();
                }
            }
        }    
    }
}
