Forms Data Controls :: Sql Update Not Working Through Webform?
Apr 8, 2010
I am Chandan Pednekar an IT student completing my final year. I am developing a data driven website for my final year project. I have written a code behind file in c# which takes a value from a datagrid to retrieve values in textboxes for further updating.
I have coded the datagrid on another page. My problem is that, even when I click update(on editEmp.aspx) I straight away get redirected to the datagrid page(manageEmp.aspx I have redirected after successful update) but the database just doesn't gets updated. I am using sqlCommand Object with executeNonQuery method.
I don't even get errors. It just gets redirected and the database isn't even updated.

I am trying to make a simple form that is positioned within a contentHolder. The "CommitChange" Function should do a simple action - update a message to the data in the textBoxes in the form. However, though I change the text through input (writing in the textBox txtEmail [URL] for instance), the values stay the same as they were when the page loaded. Why Does the page not update the values in the textBoxes?
Here is the function:
protected void CommitChange(object sender, EventArgs e)
{
ContactMessage messageToUpdate = new ContactMessage(
idToEdit,txtName.Text,txtEmail.Text,txtPhone.Text,txtMsg.Text,DateTime.Now.ToShortDateString(),
int.Parse(DdlStatus.SelectedValue),int.Parse(DdlSubject.SelectedValue),txtAddress.Text,txtCity.Text,
txtMobile.Text,txtInnerText.Text);
BLLContactMessage.updateMessage(messageToUpdate);
lblOutput.Text = "Message Updated";
lblOutput.Visible = true;
}

Here is my asp and the code behind code. When I click edit and enter a new weight value, the system does not maintain that value, but displays back the original one (if I press enter I see that happening or through debug).
What am I missing?
protected SqlDataSource GetSqlDataSource()
{
SqlDataSource dsL = new SqlDataSource();
dsL.ID = "ds1";
// You can use this utility class to get the connection string
dsL.ConnectionString = DBUtility.GetConnectionString();........

I have a formview and data source that opens in the edit template and allows the user to update a few free form text fields. I also have some drop down boxes that allow a DOB to be built and populate another text box. All of this was working fine yesterday, and today somehow I hosed it and can not find the cause. I have rebuilt this page three times to get it working again, but I can't figure out what I am doing wrong to break it.

Here is the DataSource....

Background: I open a page that has a detailsview control using Accessdatasource. It is automatically opened with the row I want to update as I get there by passing the key as a URL parm. The update works for all fields except 2 template fields I added. I added a field for update date and updated by which I want the code to populate in the code behind so the user does not enter it. I have the same login on another page using an insert and it works fine. I cannot figure out what is wrong on the update and I tried everything. The code behind is in the OnItemUPdating event. code behind:
protected void set_update_date(Object sender, EventArgs e)
{
TextBox tbdate = (TextBox)DetailsView1.FindControl("TextBox_update");

I have a formview that I open to the edit template, some textboxes are not available and some are populated by dropdown lists, and the update function works fine.
As soon as I add some logic to the code behind page for the update control, the UPDATE link on the formview stops updating my DB.

I have an Objectdatasource configured with Select, Insert, Update & Delete queries in a Dataset. This datasource is linked to my Gridview. I do not require all fields in the table to be displayed or updated in my grid so i have turned off the Visible property on several.
However, when i go into Edit mode and trigger the UPDATE to the database table, i get NULL values updated in the columns i set False for the Visible property.
How can i remove these columns from the GridView and the Edit mode and still have them UPDATE with their current values instead of being overwritten with NULL's?

I have a record in gridview contains string with special character like single quotes( ' ) etc..I've a edit button in gridview when i click on edit button of any record of Gridview then corresponding record shown to text box.
But on that time single quote looks like below ....
Before edit button click string in gridview cell, a testimonial or show consists of a person's written or spoken statement
After edit button click string in textbox, a testimonial or show consists of a person's written or spoken statement but when I click update button shows following error :
"A potentially dangerous Request.Form value was detected from the client (ctl00$ContentPlaceHolder1$tb_comment="...f a person's written or sp...")"
What is the solution so that single quote shows as it original format as it looks in gridview cell when i click on edit button.

I have a gridview I create dynamically and one of the columns is a checkbox. I need to set an event handler on this control for checkedchanged. everything appears to work fine except for one thing....even though I can see my WebForm controls they are all null..(even thogh I know they are not) So I basically cant do anythign to the controls in the event handler. Here is teh code I use to create teh dynamic column in the gridview.
EtscUtilsUI.ALMSSECSRV.EALMSAppRoles ealmsapprole =
new EtscUtils.EtscUtilsUI.ALMSSECSRV.EALMSAppRoles();//Thsi
is the webform code behind partial class.
CheckBox chk =
new
CheckBox();
chk.ID = _columnName;
chk.DataBinding += new
EventHandler(chk_DataBinding);
//Attaches the data binding event.
chk.AutoPostBack = true;
chk.CheckedChanged += new
EventHandler(ealmsapprole.Dyn_CheckChanged);
container.Controls.Add(chk);
chk.Enabled = true;
This is the code for the event Handler
internal
void Dyn_CheckChanged(object sender,
EventArgs e)
{
string err =
"";
try
{
if (lblAppID.Text !=
"")
}
that label come back as null event though a previous event set its value successfully if I try to reference the gridview itself I get the error Object reference not set to an instance of an object.

I am trying to find an efficient way of displaying images (about 140x140px) in a webform. We cannot use paging, so we need to display all these images in the same webform.I noticed that facebook (and other sites) lets you display all your images in one page. For a profile qith about 1000 photos, facebook somehow downloads only enough so that the visitor can see images on the screen. Once you scroll, it seems to only download enough so that the visitor can again see something on screen. It works like a good text editor.... instead of displaying a huge file onscreen (like notepad does) and freezing, it only displays enough for the reader to see.

I'm just using a simple slideToggle function of jQuery. It works properly in my HTML file. But whenever I take codes into a ASP.NET WebForm project, script doesn't work. I can't achieve slide effect.
Is this a known issue? It's probably a popular mistake done by developers though. What could be the problem?
(I didn't copy&paste any code because of I thought this is not a specific situation, but I can show codes if you want)

I am trying to create a recipe system that will pull material amounts from an already built inventory database upon request for testing purposes of the different recipe runs. What is throwing me for a loop is that each time a user will request a recipe comparison they will have a different number of recipe trial runs for comparison purposes. In order to do this I'm guessing you will need to generate a gridview-like control with a dynamic number of columns which would be specified on a web form page prior to arriving at the recipe formulation page which will contain the control for the recipe formulation. As a result the user will have different columns and rows on this formulation page, with the rows being a static number of 30 (30 being maximum amount of ingredients to include in each recipe). The columns will contain the recipes to be compared, i.e. ProductRun1, ProductRun2, ProductRun3, where the number of ProductRunX will be determined by user input. So the user when they come to this aspx page will be presented with a blank editable grid of X columns by 30 rows deep. The left-most column will contain the ingredient names in a drop down box for users to select to input into their recipe and the rest of the columns will be editable fields where the user can type in the amount of each material to be used. The setup will look roughly like this:
| ProductRun1 | ProductRun2 | ProductRun3 |
ProductRun4 | ... |
-------------------------------------------------------------------------------------------------------
Material1 | Material1_Amt | Material1_Amt | Material1_Amt | Material1_Amt | ...|
-------------------------------------------------------------------------------------------------------
Material2 | Material2_Amt | Material2_Amt | Material2_Amt | Material2_Amt | ...|
-------------------------------------------------------------------------------------------------------
Material3 | Material3_Amt | Material3_Amt | Material3_Amt | Material3_Amt | ...|
-------------------------------------------------------------------------------------------------------
(...)
-------------------------------------------------------------------------------------------------------
Material30 | Material30_Amt | Material30_Amt | Material30_Amt | Material30_Amt | ...|
-------------------------------------------------------------------------------------------------------
So my question is how would I go about tackling something like this and what controls would I use. All of the forum posts around the internet show the GridView control being tied to data in a database already and not having the ability to have a fully blank and editable table upon the page loading so that it can accept user input. Another wrench into the situation is that the column numbers can vary. What control would be used in this situation or would it be better to use just a repeater of textboxes to build this type of control? Another thing is once the control is built how can you pull the data from such a control with the intentions of entering it inside a sql server database?

Using VWD 2010 Express.
I tried to put a ListView onto a webform but got an error right after that:
Error Creating Control - ListView1
The 'CssClass' property cannot be set declaratively.
BTW, does ListView support horizontal/vertical scroll bar? As I might have about 50 records in maximum, so need to have horizontal and vertical scroll bars. But do not need paging.
