How to make GridView DropDown list select the row, and execute the OnSelectedIndexchange method?












0















I hope the question I asked is accurate for I am trying to achieve. I have a GridView that is displaying data from an SQL source. I need one of the columns to be a dropdown list. I also am searching for a way to when I open the dropdown menu it selects the row then executes the added OnSelectedIndexChange event.



I am pulling the cell data of the respective selected row and submitting that data to an SQL table. Is there a way to NOT select the row and use the change of the drop down list as the identifier for the row? I ask that because there is an additional post back when selecting the row. I searching for the ability to drop the menu down, and when the new value is selected execute change event (which submits the row data to a db.)



If I have to select, then I have to select. But the biggest problem I am currently have is the dropdown value selected is not passing through to C#. Here is the Gridview and C# showing what I am doing. I have much commented out because I can't see why it won't pass through the value.



<div class="CurrentMonthTab" style ="height:350px; width:90%; margin-left:15px;  overflow-y: scroll; overflow-x: hidden">        
<asp:GridView ID="GridView1" runat="server" AllowSorting="True" AutoGenerateColumns="False"

Here is the GridView and I have a template field for the dropdown menu.

// string NewUw = ddlUnderWriter1.SelectedValue;


DateTime dateUpDated = DateTime.Now; //Inserts a dateUpdated record
if (String.IsNullOrEmpty(NewUw))
{
string empty = "empty fin box";
MessageBox.Show(empty);
}
else
{
MessageBox.Show(NewUw);
}

// int UpR = Int32.Parse(vRenewalReport.SelectedRow.Cells[9].Text); //UniqProducer. This will always submit NULL due to not
// intially receving the UniqProducer data in the GridView

/*
string query = "INSERT INTO [GTU_Apps].[dbo].[Reviewed_Renewal_Policy] (UniqClient, Client, [Expiring_Policies], Premiums, TotalPremium, UniqBroker, ExpDate, NewUw, Company, Broker_Name, Reviewed, DateUpdated) " +
"VALUES (@UniqCNT, @Client, @ExpPolicyNums, @Premium, @TotalPremium, @Ub, @ExperationDate, @NewUw, @Company, @Broker, @Reviewed, @dateUpDated)";

using (SqlConnection conn = new SqlConnection("Data Source=GTU-BDE01;Initial Catalog=GTU_Apps;Integrated Security=True"))
{
using (SqlCommand comm = new SqlCommand(query, conn))
{
comm.Parameters.AddWithValue("@UniqCNT", UniqCNT);
comm.Parameters.AddWithValue("@Client", Client);
comm.Parameters.AddWithValue("@ExpPolicyNums", ExpPolicyNums);
comm.Parameters.AddWithValue("@Premium", Premium);
comm.Parameters.AddWithValue("@TotalPremium", TotalPremium );

comm.Parameters.AddWithValue("@Reviewed", Reviewed);
comm.Parameters.AddWithValue("@dateUpDated", dateUpDated);
conn.Open();
comm.ExecuteNonQuery();
conn.Close();
}
}*/
End(sender, e);
}


Here is the code behind. Much of this is commented out because I needed to isolate the dropdown and figure out why it wasn't passing through the value. You can see I'm checking to see if the string is null or empty. Then displaying it quickly with a messagebox for testing purposes. Even when I purposely select the row, then make the dropdown list change, it will show me it's empty. Any help would be greatly appreciated.

      Here is the code behind. Much of this is commented out because I needed to isolate the dropdown and figure out why it wasn't passing through the value. You can see I'm checking to see if the string is null or empty. Then displaying it quickly with a messagebox for testing purposes. Even when I purposely select the row, then make the dropdown list change, it will show me it's empty. Any help would be greatly appreciated.
