You should post any code that you are having problems with in the thread (because apparently some people can't open the files attached).
Anyways, you need a TextBox on the page. Then you need to access the Text in the TextBox (using the TextBox.Text property). Once you've got that you should use it to update your database.
The best way to supply this value (that has been provided by the end user) is to use the SqlCommand.Parameters property (if you're using the SqlCommand object).

I have an updatable Gridview control that I cannot seem to URL encode a textbox in one of the columns. I cannot encode some of the other controls in the row, so the solution from the msdn site doesn't work in my case. I only want to encode the single textbox. However, with the code I have, I don't get any errors, and the database is updated, but the column that is edited becomes empty in the database. Here is what I have in the gridview rowupdating:
I've been trying to resolve this issue for like 10 hours but with no luck. I am trying to load data from a db to text boxes and allow the user to enter his/her modifications and click a button to update the db with the entered value in the textboxes. The problem is the entered data are not sent to the db but the data that are loaded when the page is loaded is what it goes to the db. I also tried vb codes and javascript to change the data of the textbox but that did not work.
I'm using following DropDownList event to select an employee from MS SQL Server 2005 and showing the employee's information on TextBox.
protected void employeeDropDownList_SelectedIndexChanged(object sender, EventArgs e) { EmployeeDAL employeeDAL = new EmployeeDAL(); DataTable dataTable = employeeDAL.GetEmployeeData(); for (int i = 1; i <= dataTable.Rows.Count; i++)......
But the problem is... values of the TextBoxes are not changing. I mean TextBoxes are keeping previous values those were assigned in employeeDropDownList_SelectedIndexChanged event. But why?
I'm trying to set up an update button to update the infomation in my database using a stored procedure and method with the following code but when I click the button it doesn't add the updated text so i debugged the code and saw that the line "bool success = DataAccess.UpdateAboutUs(ID.Text, txtHeader.Text, txtHeader2.Text, txtDescription.Text);" was still taking the text that was loaded into the textboxes.
I retrieve a record on my database through Page_Load event here's the content of my Code:
hMenuID.Value = Request.QueryString["id"]; //Display information of links on the entries cnDBConnection.ConnectionString = clsFunction.strConnection; cnDBConnection.Open(); cmModule.Connection = cnDBConnection; cmModule.CommandText = "SELECT * FROM modules WHERE id=" + clsFunction.ReplaceString(hMenuID.Value.ToString()); rdModule = cmModule.ExecuteReader(); if (rdModule.HasRows == true) { rdModule.Read(); txtModuleLabel.Text = rdModule["name"].ToString(); txtModuleLink.Text = rdModule["link"].ToString(); cboParentID.SelectedValue = rdModule["menuid"].ToString(); } cmModule.Connection.Close(); rdModule.Close(); cnDBConnection.Close();
So, the data appears on my textboxes and a combo box. I tried to modify the content of my textbox and click on the Update button. Unfortunately, there's no modification that happen. Here's my code in the Update button
I have a question regarding to the text in the html code. I would like to know if there is a way to change the content text in the html with text that has been written in textbox. For example i have following text in html, so how can I replace this text by using a text box in the server side.
I want to display the text entered in a textbox on a label character by character. I.e, if I enter a character in textbox, I need to display that character in the label. Up to the length of the textbox, this procedure has to done for the label also.
I have a server side procedure that opens a tcp socket to a server then recieves chunks of data from the server. The server side code does this in a loop, collects the data as a string, then finally displays the data in a textbox. It all works fine.
My problem is, as the chunks of bytes are returned, I need to update a client textbox or lable showing bytes received on each iteration of the loop. I've tried injecting client side java and I've tried using such things as the updatepanel and/or updateprogress controls. I haven't gotten anything to work. It always seems to only update the client on the last iteration. i.e. in a server side procedure/loop, update a client side textbox/label. Or maybe tell me what I am doing wrong? This is some of the code I am using now without using an updatepanel or updateprogess:
I have a radiobuttonlist control in an AJAX tabpanel, which I would like not to postback whenever the selected item is changed. But I do want to modify the text in a textbox, that is within a separate updatepanel, to be the text of the new selected item.

Depending upon some condition I want to send the mail to the xyz user which will have two links "Accept" and "Reject" in the message body. When the recepient clicks either of the link an update/insert should be performed in the database against a particular record. For this , when I will be sending the mail, I will be requiring to send some unique Id along with the mail depending upon which I will be able to decide which record to update in the database. I am using SQl Server 2008 and C#.net. Does any one know how to implement it in VS 2008.
I get some data from the database that I want to use to update another Database row.I know how to do that if I put the first value on a label and then use that.//First I get the Name I want
I have a number of manually written scripts (.sql) for tables, views and stored procedures that are used from an ASP.NET application. These scripts drop the object and recreates them. I need a way to update the database when the scripts change without deleting the object. For example, when a column is added to an existing table that has rows in it, I would need to update this table with this extra column without losing the rows.
I need a way to "update" the database on a single click (I can hook up the changes using a batch file). Does Visual Studio support this kind of functionality?
I have a grid view and have five dropdownlist on it. I have edit update and cancel edit buttons on each row.
Drop down list is updating the database, but only first value in the dropdownlist even when user select second, third or any other value from the dropdownlist.
What could possible be the reason for this. Here is my row Edit/ CancelEdit and Updating Events.
I have fields for a contact. 3 of those fields are drop downs to values from another table in the database. For example, Contacts has the foreign key for departmentid which pulls from the department table to get the description. But when i click the Edit and update, this does not update my database. It acts like nothing happened.
EDIT: Just noticed this, but when i change the name and click update. I get an error telling me that EmployerCode cannot be set to null. I know that the database is set to not nullable. But i do not understand why the original value is not being pulled. When i load the contact, all three of the drop downs have values from the database loaded. Although i am seeing that all three are displaying the first item in the table and not the item the contact has in it's values. But when editing the contact, it acts like those values are not loaded and are just null.
I have an asp.net application using visual studio express 2008. On one of my pages I created a dataset from one of my database tables. I am able to delete rows and add rows to the new dataset table. I then have a button and on the click event I use the commandbuilder to update the database table. The database table updates with new rows but the deleted rows are not carried out and I can not figure out why desite spending several hours on google to resolve this issue?
Here is some of my code:
Protected Sub Button_updateDatabase_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button_updateDatabase.Click Try 'I have created a session variable for my data adapter Dim commandbuilder As SqlCommandBuilder = New SqlCommandBuilder(Session("Adapter")) Session("Adapter").UpdateCommand = commandbuilder.GetUpdateCommand Session("Adapter").DeleteCommand = commandbuilder.GetDeleteCommand 'I created a session variable for my dataset 'This update command updates new rows to my database table but not deleted rows Session("Adapter").Update(Session("CalendarDataset"), "Name") Catch ex As Exception Response.Write(ex.Message) End Try End Sub
I'm currently working on a membership system for my web application, which is based on forms authentication from the framework.I created some users with the integrated tool, and the login is perfectly working. But now what I want to do is to give administrator the capability to create, modify, delete users.So here is what I've got right now:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim muc As MembershipUserCollection = Membership.GetAllUsers() ComboBox1.DataSource = muc [code]....
The problem is that the record doesn't seem to be updated in the database.I made the multiple calls to Membership.UpdateUser after reading this blog entry, but it didn't change anything.A strange thing I noticed while debugging, is that when I enter the Button1_Click method, Membership.GetUser(userName) returns me values from my precedent attempt !
I have an access database where when the record is updated I would like to automatically check a box and update the date to the current date in an Access 2002-2003 database. I've tried this for several days without any resolution and can't find anything that works on the net. ...I'm new at this.
I have a form in which I display data from a database table, change the data and then update the database table. The form consists of textboxes, so all data displayed in the form is string. However - one data is int in the database table (the rest is varchar), so I need to convert it from string to int when I update the database table. How do I do it?
[Code]....
And, strangely enough, the same code doesn't work with parameters. How is that?:
