Hi all,

I'm having a difficulties here. I create a RadGrid and use an EditFormSettings for inserting new data. Within the EditFormSettings , I have a RadAutoCompleteBox ID="plant" which will get the value from database. I want,  when Users choose the Plant in RadAutoCompleteBox, system will parse the value of Latitude & Longitude to the RadTextBox which defined.

My challenge here, I'm able to retrieve the Latitude & Longitude value but unable to assign to the respective textbox. 

Please help..

My code as below;
C#

protected void Plant_TextChanged(object sender, Telerik.Web.UI.AutoCompleteEntryEventArgs e)
{
   string a = e.Entry.Text;
   foreach (GridEditableItem item in RadGrid2.EditItems)
    {  
        RadTextBox lati = (RadTextBox)item.FindControl("plantLat2");
        RadTextBox longi = item.FindControl("plantLong2") as RadTextBox;
        SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ibmsConnectionString"].ToString());
        SqlCommand cmd = new SqlCommand("plant_GPS_list", con);
        SqlDataAdapter da = new SqlDataAdapter(cmd);
        con.Open();
        da.SelectCommand.CommandType = CommandType.StoredProcedure;
        da.SelectCommand.Parameters.Add("@Plant", SqlDbType.VarChar, 50);
        da.SelectCommand.Parameters["@Plant"].Value = a;
        SqlDataReader dr = da.SelectCommand.ExecuteReader();
        try
        {
            if (dr.Read())
            {
                lati.Text = dr["Latitude"].ToString();
                longi.Text = dr["Longitude"].ToString();
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
        con.Close();
    }
}

Hello Lawrence,

Would you try to replace your handler with the following and see if it works on your side also:

protected void Plant_TextChanged(object sender, Telerik.Web.UI.AutoCompleteEntryEventArgs e)
{
    string a = e.Entry.Text;
 
    RadAutoCompleteBox racb = sender as RadAutoCompleteBox;
    GridEditFormItem item = (GridEditFormItem)racb.NamingContainer;
 
    RadTextBox lati = (RadTextBox)item.FindControl("plantLat2");
    RadTextBox longi = item.FindControl("plantLong2") as RadTextBox;
    SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ibmsConnectionString"].ToString());
    SqlCommand cmd = new SqlCommand("plant_GPS_list", con);
    SqlDataAdapter da = new SqlDataAdapter(cmd);
    con.Open();
    da.SelectCommand.CommandType = CommandType.StoredProcedure;
    da.SelectCommand.Parameters.Add("@Plant", SqlDbType.VarChar, 50);
    da.SelectCommand.Parameters["@Plant"].Value = a;
    SqlDataReader dr = da.SelectCommand.ExecuteReader();
    try
    {
        if (dr.Read())
        {
            lati.Text = dr["Latitude"].ToString();
            longi.Text = dr["Longitude"].ToString();
        }
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.Message);
    }
    con.Close();
}


What I changed is the item used to find the control. If this does not solve the problem, please open a support ticket and send us a runnable sample, so we could recreate locally your case and investigate it further. Here is an article on Isolating a problem in a sample project.
