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.
