I have an issue with my default value for the textboxes on the form. When the page loads the textboxes all have zeros in them. When a user enters the data and clicks submit the data is saved and the page reloads but the textboxes are empty. What did I do wrong? I set the textbox property Text to "0".

ASP.NET

<asp:TextBox ID="TextBoxTNUGSC" runat="server" Width="180px" Text= "0"></asp:TextBox>

Code Behind for the Submit Button:

C#

protected void Submit_Click(object sender, EventArgs e)
        {
            
            SqlConnection con = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["HotConnectionString"].ConnectionString);
            con.Open();

            SqlCommand cmd = new SqlCommand("Insert into Table22 (INST_ID, UNITID, ASTUDENTS, ACOMPLETED, ATRANSFERS, BSTUDENTS, BCOMPLETED, BTRANSFERS, YEAR, DATE, TIME) values (@INST_ID, @UNITID, @ASTUDENTS, @ACOMPLETED, @ATRANSFERS, @BSTUDENTS, @BCOMPLETED, @BTRANSFERS, @YEAR, @DATE, @TIME)Insert into Table23 (INST_ID, UNITID, ASTUDENTS, ACOMPLETED, ATRANSFERS, BSTUDENTS, BCOMPLETED, BTRANSFERS, YEAR, DATE, TIME) values (@INST_ID, @UNITID, @ASTUDENTS, @ACOMPLETED, @ATRANSFERS, @BSTUDENTS, @BCOMPLETED, @BTRANSFERS, @YEAR, @DATE, @TIME)", con);

            cmd.CommandType = CommandType.Text;
            cmd.Parameters.AddWithValue("@ASTUDENTS", TextBoxTNUGSC.Text);
            cmd.Parameters.AddWithValue("@ACOMPLETED", TextBoxTNUGSCD.Text);
            cmd.Parameters.AddWithValue("@ATRANSFERS", TextBoxTTOUG.Text);
            cmd.Parameters.AddWithValue("@BSTUDENTS", TextBoxTNGSC.Text);
            cmd.Parameters.AddWithValue("@BCOMPLETED", TextBoxTNGSCD.Text);
            cmd.Parameters.AddWithValue("@BTRANSFERS", TextBoxTTOG.Text);
            cmd.Parameters.AddWithValue("@YEAR", TextBoxYEAR.Text);
            cmd.Parameters.AddWithValue("@DATE", TextBoxDATE.Text);
            cmd.Parameters.AddWithValue("@UNITID", TextBoxUNITID.Text);
            cmd.Parameters.AddWithValue("@INST_ID", TextBoxINST_ID.Text);
            cmd.Parameters.AddWithValue("@TIME", lblTime.Text);
           
            cmd.ExecuteNonQuery();
            con.Close();

            if (Page.IsValid)
            {
                ScriptManager.RegisterStartupScript(this, this.GetType(), "script", "alert('You Have Successfully Submitted the Cohort');", true);
            }
            else
            {
                Response.Redirect("Gradrate.aspx"); 
            }

            TextBoxUNITID.Text = string.Empty;
            TextBoxTNUGSC.Text = string.Empty;
            TextBoxTNUGSCD.Text = string.Empty;
            TextBoxTTOUG.Text = string.Empty;
            TextBoxTNGSC.Text = string.Empty;
            TextBoxTNGSCD.Text = string.Empty;
            TextBoxTTOG.Text = string.Empty;
            
        }

'What did I do wrong?'
To answer this question, we would need to see your code. Please show it to us.

Computer Wiz99 7-Jan-14 10:53am

Sorry about that. I thought I did.

Sibasisjena 7-Jan-14 10:51am

No need to do any thing. The values will remain same after the post back

Computer Wiz99 7-Jan-14 10:53am

No the values are gone after post back.

Sibasisjena 7-Jan-14 10:52am

I do agree with Phil

In the page load check the text in empty or null, if yes then assign 0. Remove Text="0" from ASPx page

Computer Wiz99 7-Jan-14 11:06am

Is there any other way to do this in the Design view?

Computer Wiz99 7-Jan-14 13:18pm

Ok. I have tried the Page Load on the TextBoxes and it worked for the first time the page load but after the submit button was clicked it was cleared out. What is the problem?

Sibasisjena 7-Jan-14 11:15am

If we will do this in design view, then the text value will be always 0 according to your above code.

Post your code behind.

Computer Wiz99 7-Jan-14 13:20pm

I don't have any code behind for the textboxes to have zeros. I thought that it could be done on the .aspx page. Can you give me an example of the code behind for this?

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 7-Jan-14 13:25pm

No I am asking about the .cs page where you have written the Button click events and all.

Computer Wiz99 7-Jan-14 13:39pm

Ok. I have added the code behind for the Submit Button.

Solution 2

Please try to add EnableViewState as true in page registration tag in the top of the page. If u had use Update panel pls put all controls in a single update panel like TextBox and Save Button also.

Solution 4

I would take this:

C#

TextBoxUNITID.Text = string.Empty;
TextBoxTNUGSC.Text = string.Empty;
TextBoxTNUGSCD.Text = string.Empty;
TextBoxTTOUG.Text = string.Empty;
TextBoxTNGSC.Text = string.Empty;
TextBoxTNGSCD.Text = string.Empty;
TextBoxTTOG.Text = string.Empty;

And change it to this:

C#

TextBoxUNITID.Text = "0";
TextBoxTNUGSC.Text = "0";
TextBoxTNUGSCD.Text = "0";
TextBoxTTOUG.Text = "0";
TextBoxTNGSC.Text = "0";
TextBoxTNGSCD.Text = "0";
TextBoxTTOG.Text = "0";

Problem

The TextBoxes are blanked out because you are making them by the following code inside Button Click Event.

C#

TextBoxUNITID.Text = string.Empty;
TextBoxTNUGSC.Text = string.Empty;
TextBoxTNUGSCD.Text = string.Empty;
TextBoxTTOUG.Text = string.Empty;
TextBoxTNGSC.Text = string.Empty;
TextBoxTNGSCD.Text = string.Empty;
TextBoxTTOG.Text = string.Empty;

Please understand that when you click on Button, it Posts back and hits the Page Load Event and loads all the controls by default. So, at this moment, your TextBox value would be 0. But after that it hits the Button Click Event and inside this Event you are making them blank.

So, they are blanked out.

I hope if you remove these lines, those TextBoxes would load default values as 0. :)
