I am beginner.radio button not working properly. I dn't know what is a problem
protected void RadioButton1_CheckedChanged1(object sender, EventArgs e)
{
if (RadioButton1.Checked == true)
{
Label1.Text = "Upload our video file";
RadioButton2.Checked = false;
}
else
{
Label1.Text = "Upload our image file";
RadioButton1.Checked = false;
}
}
public void upload()
{
SqlCommand cmd = new SqlCommand("insert into video_info(Name,path,user_name,email,comment)values(#Name,#path,#user_name,#email,#comment)", con);
cmd.Parameters.AddWithValue("#Name", txt_file.Text);
cmd.Parameters.AddWithValue("#path", "video/" + fileuplod.FileName);
cmd.Parameters.AddWithValue("#user_name", use_name.Text);
cmd.Parameters.AddWithValue("#email", email.Text);
cmd.Parameters.AddWithValue("#comment", comment.Text);
fileuplod.SaveAs(Server.MapPath("~/video/" + fileuplod.FileName));
cmd.ExecuteNonQuery();
}
protected void submit_Click(object sender, EventArgs e)
{
upload();
}
}
What I want to do.I have two radio button.Image and video.Suppose user select image.then all the detail will save on image table or if user click on video.All the detail goes to image_database.
May be my logic is wrong.
put auto postback to true in radiobutton property
Try this
public void upload(string query)
{
SqlCommand cmd = new SqlCommand(query, con);
cmd.Parameters.AddWithValue("#Name", txt_file.Text);
cmd.Parameters.AddWithValue("#path", "video/" + fileuplod.FileName);
cmd.Parameters.AddWithValue("#user_name", use_name.Text);
cmd.Parameters.AddWithValue("#email", email.Text);
cmd.Parameters.AddWithValue("#comment", comment.Text);
fileuplod.SaveAs(Server.MapPath("~/video/" + fileuplod.FileName));
cmd.ExecuteNonQuery();
}
protected void submit_Click(object sender, EventArgs e)
{
string query;
if (RadioButton1.Checked == true)
{
query="insert into video_info(Name,path,user_name,email,comment)values(#Name,#path,#user_name,#email,#comment)";
Label1.Text = "Upload our video file";
RadioButton2.Checked = false;
}
else
{
query="insert into Image_info(Name,path,user_name,email,comment)values(#Name,#path,#user_name,#email,#comment)";
Label1.Text = "Upload our image file";
RadioButton1.Checked = false;
}
if(query!="")
{
upload(query);
}
}

What you are doing on a post back is:
First show the results due to code in your Page_Load
Then perform event handlers, so if you pushed the Save button, the saveTask_Click will be performed, which adds a record to the database. You don't update your grid view datasource, but just call DataBind() afterwards which still binds the original DataSource.
Imo you shouldn't update your grid view on Page_Load. You should only show it initially on the GET (!IsPostBack).
And at the end of saveTask_Click you have to update your grid view again.
So move the code you need to show the grid view to a method you can call on other occasions:
protected void ShowGridView() {
String pId = HttpUtility.UrlDecode(Request.QueryString["pID"]);
string query = "Select * from Tasks where S_ID=" + labelID.Text;
SqlConnection con = new SqlConnection(str);
SqlCommand com = new SqlCommand(query, con);
con.Open();
SqlDataReader sdr = null;
sdr = com.ExecuteReader();
dt = new DataTable();
dt.Columns.AddRange(new DataColumn[5] { new DataColumn("Id"), new DataColumn("Description"), new DataColumn("Status"), new DataColumn("Sprint_ID"), new DataColumn("pID") });
while (sdr.Read())
{
dt.Rows.Add(sdr["T_ID"].ToString(), sdr["T_Description"].ToString(), sdr["T_Status"].ToString(), labelID.Text,pId);
}
GridView1.DataSource = dt;
GridView1.DataBind();
con.Close();
}
Then call it in your Page_Load on !IsPostBack
if (!IsPostBack)
{
ShowGridView();
PanelTaskForm.Visible = false;
Panel1.Visible = false;
}
else if(IsPostBack){
PanelTaskForm.Visible = true;
Panel1.Visible = true;
}
Then after adding the row in saveTask_Click you can call ShowGridView() to see the new result.
if (com.ExecuteNonQuery() == 1)
{
TaskStatus.Text = "Task Successfully Saved ";
//GridView1.DataBind();
ShowGridView();
}
else
{
TaskStatus.Text = "Task not Saved";
}
I have a problem when I change dropdownlist1 item, The changed item not being accessed on the event of DropDownList1_SelectedIndexChanged.
Here is my code...
namespace My_News.Views.Shared
{
public partial class Master : System.Web.UI.MasterPage
{
SqlDataReader dr;
string user_id = "";
protected void Page_Load(object sender, EventArgs e)
{
/* user login information */
if (Session["status"] != null)
{
Button1.Text = "Logout";
Button2.Visible = true; ;
Button2.Text = Session["name"] as string + "'s Profile";
Button3.Enabled = true;
DropDownList1.Enabled = true;
user_id = Session["reg_id"] as string;
DropDownList1.Items.Clear();
using (SqlConnection connection = new SqlConnection(ConfigurationManager.ConnectionStrings["Connection_String"].ConnectionString))
{
using (SqlCommand cmd = new SqlCommand())
{
cmd.CommandText = "SELECT DISTINCT[news_category] from [news_profile] WHERE [user_id]='" + user_id + "'";
cmd.Connection = connection;
connection.Open();
dr = cmd.ExecuteReader();
while (dr.Read())
{
DropDownList1.Items.Add(dr[0].ToString());
}
connection.Close();
}
}
}
else
{
Button1.Text = "Login";
Button2.Visible = false;
Button3.Enabled = false;
DropDownList1.Enabled = false;
Session.Clear();
}
}
Dropdownnlist index change event...
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
Session["news_category"] = DropDownList1.Text;
Session["reload"] = "yes";
Session.Timeout = 10;
Response.Redirect("Default.aspx");
}
}
}
Please help me.
You need to modify your code like this
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
bindDDL();
}
protected void ddl_SelectedIndexChanged(object sender, EventArgs e)
{
string s = ddl.Text;
}
public void bindDDL()
{
DataTable dt = new DataTable("Drop");
dt.Columns.Add("ID", typeof(int));
dt.Columns.Add("Name", typeof(string));
dt.Rows.Add(1, "ABCD");
dt.Rows.Add(2, "EFGH");
ddl.DataSource = dt;
ddl.DataValueField = "ID";
ddl.DataTextField = "Name";
ddl.DataBind();
}
The following is my code, I am doing project on online examination in that I have a module of question to display in this when I click on next button it should go to the next question but it is not going.
public partial class Student : System.Web.UI.Page
{
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["dbconnection"].ConnectionString);
int i=1;
Session["Number"] = i;
protected void Page_Load(object sender, EventArgs e)
{
Session["Number"] = i++;
Label1.Text = Session["Number"].ToString();
con.Open();
SqlCommand cmd = new SqlCommand("Select * from Questions where QuestionNo = '"+Label1.Text+"'", con);
SqlDataReader dr = cmd.ExecuteReader();
if (dr.Read())
{
Label2.Text = dr["Question"].ToString();
Label3.Text = dr["Ans1"].ToString();
Label4.Text = dr["Ans2"].ToString();
Label5.Text = dr["Ans3"].ToString();
Label6.Text = dr["Ans4"].ToString();
}
con.Close();
con.Open();
SqlCommand cmd1 = new SqlCommand("Select * from Answers where QuestionNo = '" + Label1.Text + "'", con);
SqlDataReader dr1 = cmd1.ExecuteReader();
if (dr1.Read())
{
Label8.Text = dr1["Answer"].ToString();
}
con.Close();
}
protected void RadioButton1_CheckedChanged(object sender, EventArgs e)
{
if (RadioButton1.Checked)
{
Label7.Text = Label3.Text;
}
}
protected void RadioButton2_CheckedChanged(object sender, EventArgs e)
{
if (RadioButton2.Checked)
{
Label7.Text = Label4.Text;
}
}
protected void RadioButton3_CheckedChanged(object sender, EventArgs e)
{
if (RadioButton3.Checked)
{
Label7.Text = Label5.Text;
}
}
protected void RadioButton4_CheckedChanged(object sender, EventArgs e)
{
if (RadioButton4.Checked)
{
Label7.Text = Label6.Text;
}
}
protected void Button1_Click(object sender, EventArgs e)
{
if (Label7.Text == Label8.Text)
{
Label9.Text = "Your Answer is correct";
}
else
Label9.Text = "Your Answer is incorrect";
}
protected void Button2_Click(object sender, EventArgs e)
{
i++;
Session["Number"] = i;
Response.Redirect("Student.aspx");
}
}
So many bad things in this code.
You should always give names to your variables properly.
Don't concatenate SQL queries because security reasons like SQL Injection
You should use Session["Number"] to select the question number rather than Label1.Text.
Use session when it was only necessary.
First thing that you are doing wrong is how you are trying to store value of i in your Session. You are overwriting it every time you get into the method and thus resulting in same question number on each button click.
Second, you should parametrized your queries.
On each button click you should retrieve the value of i from your session and then increment it and again store it in the session. like:
int i = 0;
if (Session["Number"] == null)
{
Session["Number"] = i;
}
else
{
i = Convert.ToInt32(Session["Number"]);
}
//Later To increment Session
Session["Number"] = ++i; //First increments, then assigns the value
You should also use ++i instead of i++ since that will store the value of i before increment.
Type or namespace definantion,end of file expected
public partial class contact : System.Web.UI.Page

protected void Button1_Click1(object sender, EventArgs e)

{
foreach (Control ctrl in ctrls)
{
if (ctrl is TextBox)
((TextBox)ctrl).Text = string.Empty;

You missed to close Button1_Click1. You're missing a }

{
/* Label2.Text = "name is compulasry";*/

con.Open();
cmd = new SqlCommand("insert into Deatil values('"+ TextBox1.Text +"')", con);
cmd.ExecuteNonQuery();
ClearInputs(Page.Controls);
con.Close();
}
} // <-- This is missed
And you need to remove an extra } at the end
void ClearInputs(ControlCollection ctrls)
{
foreach (Control ctrl in ctrls)
{
if (ctrl is TextBox)
((TextBox)ctrl).Text = string.Empty;
ClearInputs(ctrl.Controls);
}
}
} // <-- Remove this

I suspect the code loading the grid is being invoked upon postback, which is causing the data to be pulled from the database when you don't want it to.
Yes - I think you want the code to only load if it is not a postback. You can use the Page.IsPostBack property for this.
Something like this:
protected void Page_Load(object sender, EventArgs e)
{
userLabel.Text = Session["UserName"].ToString();
if (!IsPostBack) {
SqlDataReader myDataReader = default(SqlDataReader);
SqlConnection MyConnection = new SqlConnection(ConfigurationManager.ConnectionStrings["RescueAnimalsIrelandConnectionString"].ConnectionString);
SqlCommand command = new SqlCommand("sp_EditRescueDetails", MyConnection);
if (!User.Identity.IsAuthenticated)
{
}
else
{
command.Parameters.AddWithValue("#UserName", userLabel.Text.Trim());
}
try
{
command.CommandType = CommandType.StoredProcedure;
MyConnection.Open();
myDataReader = command.ExecuteReader(CommandBehavior.CloseConnection);
// myDataReader.Read();
GridViewED.DataSource = myDataReader;
GridViewED.DataBind();
if (GridViewED.Rows.Count >= 1)
{
GridViewED.Visible = true;
lblMsg.Visible = false;
}
else if (GridViewED.Rows.Count < 1)
{
GridViewED.Visible = false;
lblMsg.Text = "Your search criteria returned no results.";
lblMsg.Visible = true;
}
MyConnection.Close();
}
catch (SqlException SQLexc)
{
Response.Write("Read Failed : " + SQLexc.ToString());
}
}
}
Don't bind your data in the Page_Load event. Create a separate method that does it, then in the Page Load, if !IsPostback, call it.
The reason to perform the databinding is it's own method is because you'll need to call it if you're paging through the dataset, deleting, updating, etc, after you perform the task. A call to a method is better than many instances of the same, repetitive, databinding code.
