I have four text boxes whose value I need to change based on the selection in a dropdown list. but when I change the value, the textboxes don't update
My codes:
<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True"
DataSourceID="Employees" DataTextField="FullName" DataValueField="FullName"
OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">
</asp:DropDownList>
<asp:SqlDataSource ID="Employees" runat="server"
ConnectionString="<%$ConnectionStrings:MyConnectionString %>"
SelectCommand="SELECT [FullName] FROM [Employees] ORDER BY [FirstName]">
</asp:SqlDataSource>
And class file:
public partial class WebForm1 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
string cn = "Data Source=.;Initial Catalog=DBRE ;Integrated Security=True";
SqlConnection scon = new SqlConnection(cn);
SqlCommand scmd = new SqlCommand("Select * from Employees where FullName = '" + DropDownList1.SelectedItem.Value + "'", scon);
SqlDataReader sdr;
try
{
scon.Open();
sdr = scmd.ExecuteReader();
txtName.Text = sdr["FirstName"].ToString();
txtSurname.Text = sdr["LastName"].ToString();
txtDepartment.Text=sdr["Dept"].ToString();
txtCostCentre.Text=sdr["CostCentre"].ToString();
}
catch (Exception ex)
{
}
finally
{
scon.Close();
}
What am i doing wrong here?
May be i think check the exception, Use Reader like or use ExecuteScalar
using (var reader = cmd.ExecuteReader())
{
if (reader.Read())
{
learerLabel.Text = reader.GetString(reader.GetOrdinal("somecolumn"))
}
}
Check this
dynamically filled DropDownList does not retain value on postback ASP.net c#
Try EnableViewState="true"
<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True" EnableViewState="true" DataSourceID="Employees" DataTextField="FullName" DataValueField="FullName"
OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">
</asp:DropDownList>
Set your dropdownlist with AutoPostBack="true" with the on selected index changed like this:
<asp:DropDownList ID="ddl" runat="server" AutoPostBack="true" OnSelectedIndexChanged="ddlPNo_selectedChanged" ></asp:DropDownList>
And in your code behind load data into your dropdownlist with the following code:
String conn = System.Configuration.ConfigurationManager.ConnectionStrings["CONSTRING"].ConnectionString;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
SqlConnection con = new SqlConnection(conn);
SqlDataAdapter da = new SqlDataAdapter("select Code from table1", con);
DataSet ds = new DataSet();
con.Open();
da.Fill(ds);
con.Close();
ddl.DataSource = ds.Tables[0];
ddl.DataValueField = "Code";
ddl.DataBind();
ddl.Items.Insert(0, new ListItem("-- select --"));
}
}
Now you can bind data on dropdownlist changed with the following code:
protected void ddl_selectedChanged(object sender, EventArgs e)
{
String strConnString = ConfigurationManager.ConnectionStrings["CONSTRING"].ConnectionString;
String strQuery = "select description from table1 where Code = #Code";
SqlConnection con = new SqlConnection(strConnString);
SqlCommand cmd = new SqlCommand();
cmd.Parameters.AddWithValue("#Code", ddl.SelectedItem.Value);
cmd.CommandType = CommandType.Text;
cmd.CommandText = strQuery;
cmd.Connection = con;
try
{
con.Open();
SqlDataReader dr = cmd.ExecuteReader();
while (dr.Read())
{
txtbdescription.Text = dr["description"].ToString();
}
}
catch (Exception ex)
{
throw ex;
}
finally
{
con.Close();
con.Dispose();
}
}
where txtbdescription is the id of your textbox.
Hope this will help.
Remove AutoPostBack="True"
<asp:DropDownList ID="DropDownList1" runat="server"
DataSourceID="Employees" DataTextField="FullName" DataValueField="FullName"
OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">
And add if (!ispostback) condition
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
if (!isPostback)
{
string cn = "Data Source=.;Initial Catalog=DBRE ;Integrated Security=True";
SqlConnection scon = new SqlConnection(cn);
SqlCommand scmd = new SqlCommand("Select * from Employees where FullName = '" + DropDownList1.SelectedItem.Value + "'", scon);
SqlDataReader sdr;
try
{
scon.Open();
sdr = scmd.ExecuteReader();
txtName.Text = sdr["FirstName"].ToString();
txtSurname.Text = sdr["LastName"].ToString();
txtDepartment.Text=sdr["Dept"].ToString();
txtCostCentre.Text=sdr["CostCentre"].ToString();
}
catch (Exception ex)
{
}
finally
{
scon.Close();
}
}
}

The GridView control has a paging option as described here: https://msdn.microsoft.com/en-us/library/aa479347.aspx
<asp:GridView ID=" productsGridView" Runat="server"
DataSourceID="productDataSource" AutoGenerateColumns="False"
AllowSorting="True" BorderWidth="2px" BackColor="White"
GridLines="None" CellPadding="3"
CellSpacing="1" BorderStyle="Ridge" BorderColor="White"
AllowPaging="True" PageSize=50>
Notice the property of: AllowPaging. You can specify the number of records per page using the PageSize property. I think the default PageSize is: 10.
You can also specify the properties programmatically e.g.
GridView1.AllowPaging=true;
GridView1.PageSize=50;
protected void submit_Click(object sender, EventArgs e)
{
BindGrid();
}
protected void BindGrid()
{
SqlConnection con = new SqlConnection();
con.ConnectionString = "Data source= LAPTOP-6\\SQLEXPRESS;Initial Catalog=training;integrated Security=true";
SqlCommand cmd = new SqlCommand();
cmd.CommandText = "Sp_PO";
cmd.CommandType = CommandType.StoredProcedure;
cmd.Connection = con;
try
{
con.Open();
GridView1.EmptyDataText = "No Records Found";
DataSet ds = new DataSet();
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(ds);
con.Close();
GridView1.DataSource = ds;
GridView1.DataBind();
}
The autofill works for the static text box, but not the dynamic one.
User needs to be able to add as many rows as necessary, and each text box should pull from the same table. There are too many records in the table to use a simple drop down... Any ideas?
This Works

The problem lies that upon selection of the date in the dropdown it will give the count of the LAST selection, not the current.
I am a novice and the only thing I can think of is some type of postback issue? The gridview populates fine with the records selected by the DDL, so I just cant get my head around why the count that is rendered is the previous selection.
protected void ddlClassDate_SelectedIndexChanged(object sender, EventArgs e)

lblRecordCounter.Text = "";

comm = new SqlCommand("SELECT (*) FROM gescdb" +
"WHERE ClassDate=" + ddlClassDate.Text, conn);
try

conn.Open();
reader = comm.ExecuteReader();

GridRegistrants.DataBind();
reader.Close();
}

In your Page_Load method you do the same, right? You have to move that code into following block:
if (!IsPostBack){
//Your code is here
}
Your DropDownList:
<asp:DropDownList ID="ddlClassDate" runat="server" AutoPostBack="true" OnSelectedIndexChanged="ddlClassDate_SelectedIndexChanged" />
Your code behind:
protected void Page_Load(object sender, EventArgs e){
if (!IsPostBack){
BindDDL();
BindGrid(ddlClassDate.SelectedValue);
}
}
protected void BindDDL(){
//Bind Your dropdownlist here
}
protected void BindGrid(string ddate){
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["gescdb"].ConnectionString);
SqlCommand comm = new SqlCommand("select * from gescdb where ClassDate = #date", conn);
comm.Parameters.Add("#date", SqlDbType.VarChar).Value = ddate;
try
{
conn.Open();
SqlDataAdapter sda = new SqlDataAdapter(comm);
DataSet ds = new DataSet();
sda.Fill(ds);
GridRegistrants.DataSource = ds;
GridRegistrants.DataBind();
}
catch
{
//...
}
finally
{
conn.Close();
}
}
protected void ddlClassDate_SelectedIndexChanged(object sender, EventArgs e){
BindGrid(ddlClassDate.SelectedValue);
}
I am trying to bind a selected item from the database in dropdownlist. I am not getting the users selected data in the dropdownlist instead it loads everything. What i need is to have a default selected value from the database along with other items. Please help me to overcome this problem. Thanking you in advance.

You have to use SelectedValue property of DropDownList.DataTextField and DataValueField are for specifying which properties from DataSource should be used as Text and Value of drop down list.
Replace these lines:
ddlInstitute.DataValueField= dr["InstituteId"].ToString();
ddlInstitute.DataTextField= dr["Institute"].ToString();
with:
ddlInstitute.SelectedValue= dr["InstituteId"].ToString();
or you can also do:
ddlInstitute.Items.FindByValue(dr["InstituteId"].ToString()).Selected = true;
You can also refer this article
Assuming you know which ID you want to have selected, try something like this:
ddlInstitute.Items.FindByValue(dr["InstituteId"].ToString()).Selected = true;
Try it as a function:
void FN_loadBranch()
{
classname cls = new classname ();
DataTable dt = new DataTable();
dt = cls.FUNCTIONNAMEINCLASS(int id);
dropdown.DataSource = dt;
dropdown.DataValueField = "valuefield";
dropdown.DataTextField = "textfield";
dropdown.DataBind();
ddlBranch.Items.Insert(0, new ListItem("--Select--", "0"));
}
In function:
public DataTable FUNCTIONNAMEINCLASS( int id)
{
try
{
using (SqlConnection cn = new SqlConnection(CLASS.ConnectionString))
{
SqlCommand cmd = new SqlCommand("[storedprocedure]", cn);
cn.Open();
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("#ID", SqlDbType.VarChar, 50).Value = id;
SqlDataAdapter sda = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
sda.Fill(dt);
return dt;
}
}
}
Use stored procedure in the function

There is Mistake in Your Query, Correct it as below.
MySqlCommand cmd = new MySqlCommand("SELECT * FROM subject WHERE Name LIKE '%" + srh + "%'", connection);
First, use a parameterized command to avoid SQL injections. Second, I think the value you are looking for is in the Text property of the input, not the Type property. Lastly, the single quotes go outside the matching characters, i.e., '%searchvalue%'.
protected void Button1_Click(object sender, ImageClickEventArgs e)
{
MySqlConnection connection = new MySqlConnection("connection string removed");
connection.Open();
try
{
var cmd = new MySqlCommand("SELECT * FROM subject WHERE Name LIKE '%#input%'", connection);
cmd.Parameters.Add("#input", editbox_search.Text);
MySqlDataAdapter da = new MySqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
GridView1.DataSource = ds;
GridView1.DataBind();
connection.Close();
}
catch (Exception e)
{
// log the exception
}
}
Try this one:
protected void Button1_Click(object sender, ImageClickEventArgs e)
{
MySqlConnection connection = new MySqlConnection("connection string removed");
connection.Open();
try
{
var cmd = new MySqlCommand("SELECT * FROM subject WHERE Name LIKE '%'+#input+'%'", connection);
cmd.CommandType = CommandType.Text;
cmd.Parameters.AddWithValue("#input", editbox_search.Text);
MySqlDataAdapter da = new MySqlDataAdapter(cmd);
MySqlDataReader dr = cmd.ExecuteReader();
da.Fill(dr);
GridView1.DataSource = dr;
GridView1.DataBind();
connection.Close();
}
catch (Exception e)
{
// log the exception
}
}
Try this query
SELECT * FROM subject WHERE Name LIKE %'" + srh + "'%
