RadioButtonList rl1 = new RadioButtonList();
rl1.Items.Add(new ListItem("yes","1"));
rl1.Items.Add(new ListItem("no","0"));
return(p1.Controls.Add(rl1));
}
Seperate the void method from the return statement.
p1.Controls.Add(r11)); has no return value and therefore cannot be used as an argument in a return statement.
Change your return statement in addrbl() to this:
p1.Controls.Add(rl1);
return p1;
Also, you should be returning the actual object type and not just an object of type object:
private Panel addrbl() {..}

I am designing a website in which I need to update a table Company in my database through CompanyDetails page with respect to the auto increment field CompanyID which is being passed through Query string from previous page named Company and only one button is there for insert and update. So my problem is I am unable to get the value of Companyid of Page_OnLoad event in SaveButtonClick event.
Note: I have already tried Session and View state, IsPostBack but in Onclick event even their value are not being maintained and are updated to 0 or null.
Here is my code......(Please ignore my coding mistakes)
using System;
using System.Web.UI;
using System.Data;
using System.Data.SqlClient;
public partial class CompanyDetails : System.Web.UI.Page
{
int Companyid = 0;
string cmdName = null;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Companyid = Convert.ToInt32(Request.QueryString["CompanyID"]);
cmdName = Request.QueryString["CommandType"];
Session["something"] = Companyid;
}
if (cmdName == "Details")
{
BindTextBoxvalues();
}
}
protected void SaveButton_Click(object sender, EventArgs e)
{
string x = Session["something"].ToString();
try
{
if (SaveButton.Text == "Save")
{
SqlCommand cmd = new SqlCommand();
String mycon = "Data Source=.; Initial Catalog=something; Integrated Security=True";
SqlConnection con = new SqlConnection(mycon);
cmd = new SqlCommand("spInsertCompany", con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("#CompanyName", SqlDbType.VarChar).Value = Name.Text;
cmd.Parameters.Add("#CompanyCode", SqlDbType.VarChar).Value = CompanyCode.Text;
cmd.Parameters.Add("#LegalName", SqlDbType.VarChar).Value = LegalName.Text;
cmd.Parameters.Add("#TaxID", SqlDbType.Int).Value = TaxID.Text;

cmd.ExecuteNonQuery();
Response.Write("<script language='javascript'>window.alert('Saved Successfully.');window.location='Company.aspx';</script>");
}
else if (SaveButton.Text == "Update")
{
SqlCommand cmd = new SqlCommand();
String mycon = "Data Source=.; Initial Catalog=something; Integrated Security=True";
SqlConnection con = new SqlConnection(mycon);
con.Open();
cmd = new SqlCommand("spUpdateCompany", con);
cmd.CommandType = CommandType.StoredProcedure;
int a = Convert.ToInt32(Companyid);
// I need the value here but it is being updated to zero here.
cmd.Parameters.Add("#CompanyID", SqlDbType.Int).Value = Companyid;
cmd.Parameters.Add("#CompanyName", SqlDbType.VarChar).Value = Name.Text;

cmd.ExecuteNonQuery();
cmd.Dispose();
con.Close();
Response.Write("<script language='javascript'>window.alert('Updated Successfully.');window.location='Company.aspx';</script>");
}
}
catch (SqlException ex)
{
ScriptManager.RegisterStartupScript(this, this.GetType(), "Message",
"alert('Oops!! following error occured : " + ex.Message.ToString() + "');", true);
}
}
protected void CancelButton_Click(object sender, EventArgs e)
{
Response.Redirect("Company.aspx");
}
private void BindTextBoxvalues()
{
SaveButton.Text = "Update";
string constr = "Data Source=.; Initial Catalog=something; Integrated Security=True";
SqlConnection con = new SqlConnection(constr);
SqlCommand cmd = new SqlCommand("select * from Company where CompanyID=" + Companyid, con);
DataTable dt = new DataTable();
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(dt);
Name.Text = dt.Rows[0][1].ToString();
CompanyCode.Text = dt.Rows[0][2].ToString();
LegalName.Text = dt.Rows[0][15].ToString();
TaxID.Text = dt.Rows[0][14].ToString();
BusinessPhone.Text = dt.Rows[0][3].ToString();
Extension.Text = dt.Rows[0][13].ToString();
FaxNumber.Text = dt.Rows[0][12].ToString();
Description.Value = dt.Rows[0][4].ToString();
IsActiveCheckBox.Checked = Convert.ToBoolean(dt.Rows[0][11]);
}
}
Any values stored in local variables need to be read from Request on every postback.
So do following
int Companyid = 0;
string cmdName = null;
protected void Page_Load(object sender, EventArgs e)
{
Companyid = Convert.ToInt32(Request.QueryString["CompanyID"]);
cmdName = Request.QueryString["CommandType"];
if (!IsPostBack)
{
if (cmdName == "Details")// be sure about string case
{
BindTextBoxvalues();
}
}
}
Or make viewstate properties
If you want to have your property available on the PostBack, do not use !IsPostBack
protected void Page_Load(object sender, EventArgs e)
{
Companyid = Convert.ToInt32(Request.QueryString["CompanyID"]);
}

i have gridview which populate date from database i want to change seclected data on dropdown SelectedIndexChanged when i select the first index it selected data from database when i chang selections it get another data try this code but nosense this is my code
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindData();
}
}
private void BindData()
{
if (ddlTguidedit.SelectedIndex==0)
{
string strQuery = "SELECT [Pdfid],[Arpdf_name],[Arpdf_des],[pdf_date] FROM [books_alaa].[dbo].[Tbl_uploadpdf]";
SqlCommand cmd = new SqlCommand(strQuery);
GridView1.DataSource = GetData(cmd);
GridView1.DataBind();
}
else
{
string strQuery = " SELECT Pdfid, Enpdf_name AS Arpdf_name, Enpdf_des AS Arpdf_des, pdf_url, pdf_date FROM Tbl_uploadpdf";
SqlCommand cmd = new SqlCommand(strQuery);
GridView1.DataSource = GetData(cmd);
GridView1.DataBind();
}
}
private DataTable GetData(SqlCommand cmd)
{
DataTable dt = new DataTable();
SqlConnection con = new SqlConnection(strConnString);
SqlDataAdapter sda = new SqlDataAdapter();
cmd.CommandType = CommandType.Text;
cmd.Connection = con;
con.Open();
sda.SelectCommand = cmd;
sda.Fill(dt);
return dt;
}
protected void ddlTguidedit_SelectedIndexChanged(object sender, EventArgs e)
{
if (ddlTguidedit.SelectedIndex == 0)
{
string strQuery = "SELECT [Pdfid],[Arpdf_name],[Arpdf_des],[pdf_date] FROM [books_alaa].[dbo].[Tbl_uploadpdf]";
SqlCommand cmd = new SqlCommand(strQuery);
GridView1.DataSource = GetData(cmd);
GridView1.DataBind();
}
else
{

SqlCommand cmd = new SqlCommand(strQuery);
GridView1.DataSource = GetData(cmd);
GridView1.DataBind();
}
}
why it doesnt work ??
Remove BindData() from !IsPostBack(). You are loading the grid data on DropDownList SelectedIndexChanged. There is no need of BindData() function to be in !IsPostBack(). BindData() function always loads no matter at what index the DropDownList is, it will always take the index as 0.
i am adding multiple checkboxes in my asp.net page by doing this:
public static CheckBox[] chck;
on pageload:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
con.Open();
SqlCommand cmd = new SqlCommand("select count(CompanyName) from Stock_Company");
cmd.Connection = con;
comno = Convert.ToInt32(cmd.ExecuteScalar());
con.Close();
chck = new CheckBox[comno];
}
}
now i have a function which is generating the checkboxes :
public void generatecheckbox1()
{
con.Open();
SqlCommand cmd = new SqlCommand("select CompanyName from Stock_Company");
cmd.Connection = con;
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
DataTable dt = ds.Tables[0];
con.Close();
for (int i = 0; i < dt.Rows.Count; i++)
{
chck[i] = new CheckBox();
chck[i].ID = "chck" + Convert.ToString(i);
chck[i].Text = dt.Rows[i]["CompanyName"].ToString();
pnlcom1.Controls.Add(chck[i]);
pnlcom1.Controls.Add(new LiteralControl("<br />"));
}
}
and i am calling this on a combobox event:
protected void ddluserwebser_SelectedIndexChanged(object sender, EventArgs e)
{
if (ddluserwebser.SelectedItem.Text == "Custom")
{
generatecheckbox1();
}
}
as far as this all are working fine ... but in a button click i want to get the select checkbox's text which i am not getting
i made a function :
public string getbsecompany()
{
string companyname = "";
string bsetricker = "";
con.Open();
SqlCommand cmd = new SqlCommand("select CompanyName from Stock_Company");
cmd.Connection = con;
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
DataTable dt = ds.Tables[0];
con.Close();
for (int i = 0; i < dt.Rows.Count; i++)
{
if (chck[i].Checked == true) **THE PROBLEM IS HERE**
{
companyname = chck[i].Text;
con.Open();
SqlCommand cmdd = new SqlCommand("select BSETickerCode from Stock_Company where CompanyName='" + companyname + "'");
cmdd.Connection = con;
bsetricker += bsetricker + "+" + cmdd.ExecuteScalar();
con.Close();
}
}
return bsetricker;
}
and i am calling it here:
protected void btnusersave_Click(object sender, EventArgs e)
{
string bsetricker = "";
bsetricker = getbsecompany();
}
the problem is i am not getting the checked box's text. when i am checking if (chck[i].Checked == true) i am gettin false and all checkboxes are checked.
What should i do now?
any help
The dynamic controls should added to page in On_Init() for each time if you want it display in page.
Else there's nothing you can get.
Plus, better not use a static value to contains checkBox List, it will cause problem when multi user access same page. You can save them in session or try this.Form.FindControls()
I using DayPilot Lite 3.1 from :
http://www.daypilot.org
Now I like to fill the calendar with value from the my sql database but I don't know how ?
Can you help me, what I need to write in the protected DataTable getData()?
Here is the code behind:
namespace Rezervacii{
public partial class Events : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
DayPilotCalendar1.StartDate = firstDayOfWeek(DateTime.Now, DayOfWeek.Sunday);
DayPilotCalendar1.DataSource = getData();
DataBind();
}
}
protected DataTable getData()
{
SqlConnection con = new SqlConnection();
con.ConnectionString = #"Data Source=.\SQLEXPRESS;Initial Catalog=Korisnik;Integrated Security=True";
SqlDataAdapter da = new SqlDataAdapter("SELECT [id], [name], [startevent], [endevent] FROM [Event] WHERE id=#id , name=#name, startevent=#startevent, endevent=#endevent", con);
DataTable dt;
dt = new DataTable();
da.Fill(dt);
return dt;
}
private static DateTime firstDayOfWeek(DateTime day, DayOfWeek weekStarts)
{
DateTime d = day;
while (d.DayOfWeek != weekStarts)
{
d = d.AddDays(-1);
}
return d;
}
protected void DayPilotCalendar1_BeforeEventRender(object sender, DayPilot.Web.Ui.Events.Calendar.BeforeEventRenderEventArgs e)
{
string color = e.DataItem["color"] as string;
if (!String.IsNullOrEmpty(color))
{
e.DurationBarColor = color;
}
}
}
Here is the code how was before I edit :
protected DataTable getData()
{
DataTable dt;
dt = new DataTable();
dt.Columns.Add("start", typeof(DateTime));
dt.Columns.Add("end", typeof(DateTime));
dt.Columns.Add("name", typeof(string));
dt.Columns.Add("id", typeof(string));
dt.Columns.Add("color", typeof (string));
DataRow dr;
dr = dt.NewRow();
dr["id"] = 0;
dr["start"] = Convert.ToDateTime("15:50");
dr["end"] = Convert.ToDateTime("15:55");
dr["name"] = "Event 1";
dt.Rows.Add(dr);
return dt;
You can use something like this:
protected DataTable getData()
{
SqlConnection con = new SqlConnection();
con.ConnectionString = #"Data Source=.\SQLEXPRESS;Initial Catalog=Korisnik;Integrated Security=True";
SqlDataAdapter da = new SqlDataAdapter("SELECT [id], [name], [startevent], [endevent] FROM [Event] WHERE NOT (([endevent] <= #start) OR ([startevent] >= #end))", con);
da.SelectCommand.Parameters.AddWithValue("start", DayPilotCalendar1.StartDate);
da.SelectCommand.Parameters.AddWithValue("end", DayPilotCalendar1.EndDate.AddDays(1));
DataTable dt;
dt = new DataTable();
da.Fill(dt);
return dt;
}
