I am trying to update the row using gridview_rowupdating event but I am unable to update. I tried the code like this...
foreach (GridViewRow i in GridView1.Rows)
{
TextBox sname = i.FindControl("sname") as TextBox;
TextBox fname = i.FindControl("fname") as TextBox;
TextBox sex = i.FindControl("txtsex") as TextBox;
// Label lblpin1 = i.FindControl("lblpin") as Label;
TextBox tpin = i.FindControl("txtpin") as TextBox;
tpin.Enabled = true;
// lblpin1.Enabled = true;
string pinno;
pinno = Convert.ToString(tpin.Text.Trim());
conn2.Open();
SqlCommand cmd = new SqlCommand("update NRDetails2010 set SNAME='" + sname + "',FNAME='" + fname + "',SEX='" + sex + "' where pin='" + pinno.Trim() + "' and InstCode='" + Session["UId"] + "' and Sem='" + ddlsem.SelectedItem.Text + "' and scheme='"
+ ddlscheme.SelectedItem.Text.Trim() + "' ", conn2);
cmd.ExecuteNonQuery();
conn2.Close();
}
I am getting error at cmd.ExecuteNonQuery()
Here I am giving connection globally and opening in this event. In gridview, I am updating 3 fields depending on 4 conditions.

I have a Modified Date and Modified By column in my gridview and I want them to be updated with the current date and current user any time a user updates the row.
I converted my columns to template fields and the textboxes in the edititemtemplate are bound to my sql data columns "ModifiedDate" and "ModifiedBy"
Then I added the attached code in my RowUpdating event.
When I test the code and click the Update link on my gridview I don't get an error but the values don't update either. I put a breakpoint on the code and when I hover over "ModifiedDateLabel.Text" I see the old value of the field so I know I'm accessing the control correctly.

I'm creating a GridView in code. I can successfully attach handlers for Editing, and CancelEditing. RowUpdating never runs, however. Instead, if the GridView is in a Panel, the Edit handler is called when Update is clicked (and this is the command name I get back on the Update click, too). If the GridView is not in a panel, then the Cancel handler is called when Update is clicked (again, this is the command name I get back from clicking Update). I've searched high and low for a reason why the RowUpdating event is not getting called, and I can't find one. Does anyone out there haveHere is my code (My actual code is much more involved than this, but for testing purposes, I extracted the following code and stuck it in a new project to isolate my problem):
protected void Page_Init(object sender, EventArgs e)
{
if (!IsPostBack)

How do I get the old values in a gridview row in the row_updating event? I'm using a sqldatasource control to populate the grid and want to write the update code in the RowUpdating event. There are 10 fields displayed in the grid. I can get the value of the first field using string old_Category = e.OldValues[0].ToString();.
But it doesn't work for index items greater than 0. This doesn't work string old_Category = e.OldValues[1].ToString(); it returns an error message Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index. even though there are 10 columns in the grid.

I'm using a GridView to display some columns and rows that reside in a database. This works excellent. Because i wanted to add columns dynamically out of a List of names. Let's say we have a list with 5 names in it, then it dynamically creates a column for every name in the GridView.
Here's some code to display what i do:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
//Create columns for each student
List<Student> allStudents = new Eetlijst.Business.Students().GetAll();
allStudents.Reverse();.......
How do i create the dynamic columns for each row? I create them with a DataBound event. So when the GridView databinds, the columns get filled with data. There is also a check inside to see if the row is in edit mode or not. So when i click on the edit button next to the row, the row goes perfectly in edit mode. The code i made adds a TextBox control to the cell.
When i fill in a value and press the Update button, it can't find any controls anymore and therefore i can't get the value i entered. The control is still there in the DataBound when i put a break point after it. But as soon as i click the Update button, all the controls of the cells are gone.
I searched on the internet and all i found is that it has something to do with the application firing a postback before it reaches the RowUpdating method.
So, how can i let the controls exist that i added to the cell when it is in edit mode?

I have a gridView that is populated with a dataset from an Oracle Database.
When I click on the EDIT button, it will redisplay my gridView with textboxes so I may make some changes.
Let's say one row is currently:
OPEN_TIME = 1 CLOSE_TIME = 2
When I click EDIT, 1 and 2 are in a textbox. If I change both values to 5 and click UPDATE, it will fire a RowUpdating..
Here is the code from my APP:
Private Sub gvBusinessHours_RowUpdating(sender As Object, e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles gvBusinessHours.RowUpdating
Dim strOpenTime As String = DirectCast(gvBusinessHours.Rows(e.RowIndex).FindControl("txtOpenTime"), TextBox).Text
Dim strCloseTime As String = DirectCast(gvBusinessHours.Rows(e.RowIndex).FindControl("txtCloseTime"), TextBox).Text
End Sub
The problem is the values I am getting are the OLD ones and not the new ones... I am getting 1 and 2 and not 5 AND 5...
what I am doing wrong ?

I'm currently working on a small project and therefore created a gridview, including one bit column which has been linked with a checkbox in both the itemtemplate as the edititemtemplate (autopostback = true).Databinding for these two checkboxes has been linked (two-way) to the bit column.Now I want to display the gridview to end-users. They should be able to just click on the checkbox so they value in the database column gets changed as well (as I want to run update queries behind it), but not passing via the command column 'EDIT'.=> problem I'm having now is that the bit column in the database doesn't get updated.

I have a gridview that has 3 dropdowns. And when I am in edit mode, when updating via the RowUpdating event, I am not getting a value from my 2nd or 3rd drop downlists. Here's the code from RowUpdating:
Code:
Protected Sub gridOutdoor_RowUpdating(ByVal sender As Object, ByVal e As GridViewUpdateEventArgs)
'WHEN DEBBUGING, the text for ddBodyColor.Text is an empty string. I had selected a value prior to this event firing."
Dim ddBodyColor As DropDownList = DirectCast(gridOutdoor.Rows(e.RowIndex).FindControl("ddBodyColor"), DropDownList)
End Sub
Here's the source code for ddBodyColor:
Code:
<EditItemTemplate>
<asp:DropDownList ID="ddBodyColor" runat="server" TabIndex="2" AppendDataBoundItems="true" Enabled="true" DataTextField="bodyColor" DataValueField="bodyColor"><asp:ListItem Text="Select" Value="" /></asp:DropDownList>

Here is my situation: I have a overview of subscriptions that look simple:
Active (bool), ID (int), StartDate (datetime) and MaxUsers (int).
I've put this in a Gridview and it renders nicely.
Now everything is simply in ItemTemplates and are formatted.
Now a new feature: In the Gridview active should be a checkbox and when clicked on it, it should (de)activate the subscription. Or simply said, Active status is updated. Now me being a simpleton thinks:
[Code]....
and the cs:
[Code]....
But! the event doesnt get fired. Now I've searched with google and also through this forum and every time I get the answer: autopostback on true or use commandname. Now for this little feature I think the commandname use in combi with rowbound is overkill for such a little thing.
Now I hope I'm just missing something because this would be really nasty and stupid to make it so complicated. I like the autopostback and oncheckchanged combination because it logical, but why doesnt it work?

From a user perspective, I can list of users in a grid with some associated checkboxes. When I click on a checkbox, I want to update the database straight away. No buttons involved.
I am new to MVC.
I am trying to work out if I can do this by using a BeginForm that wraps around each checkbox. It appears not, but how can clicking on a checkbox cause a POST?
Or maybe I can use a JQuery click or change event on the Checkbox? But in a grid the id for the checkbox is repeated, and I cannot get it to work even with 1 row of data.
The code below does not work. If I can get it to work, I need to send an AJAX post to call the method on the controller with the Model.UserId and the checkbox value;

I've put a simple gridview on my Asp.net webpage. I've configured the fields via C# code:
gvMainDataGrid.AutoGenerateColumns = false;
gvMainDataGrid.AutoGenerateDeleteButton = false;
BoundField bfldSeqNmbr = new BoundField();
bfldSeqNmbr.DataField = "PKSequenceNmbr";
bfldSeqNmbr.Visible = false;
gvMainDataGrid.Columns.Add(bfldSeqNmbr);
BoundField bfldEmployeeCode = new BoundField();
bfldEmployeeCode.DataField = "Employee Code";
bfldEmployeeCode.HeaderText = "Employee Code";
gvMainDataGrid.Columns.Add(bfldEmployeeCode);
BoundField bfldProjectCode = new BoundField();
bfldProjectCode.DataField = "Project Code";
bfldProjectCode.HeaderText = "Project Code";
gvMainDataGrid.Columns.Add(bfldProjectCode);
BoundField bfldProcessCode = new BoundField();
bfldProcessCode.DataField = "Process Code";
bfldProcessCode.HeaderText = "Process Code";
gvMainDataGrid.Columns.Add(bfldProcessCode);
BoundField bfldActivityDate = new BoundField();
bfldActivityDate.DataField = "Date";
bfldActivityDate.HeaderText = "Date";
gvMainDataGrid.Columns.Add(bfldActivityDate);
BoundField bfldActivityHours = new BoundField();
bfldActivityHours.DataField = "Activity Hours";
bfldActivityHours.HeaderText = "Activity Hours";
gvMainDataGrid.Columns.Add(bfldActivityHours);
CommandField cfldDeleteButton = new CommandField();
cfldDeleteButton.ShowDeleteButton = true;
gvMainDataGrid.Columns.Add(cfldDeleteButton);
It's data source is a Dataset retrieved from a webservice. Here is the C#code to bind the data to the gridview
Service1 MyService = new Service1();
dsMainData = MyService.GetData(strIdNumber);
gvMainDataGrid.DataSource = dsMainData;
gvMainDataGrid.DataBind();
It retrieves great. No problems at all. Then, when I actually try to use the delete button, I get an error that the RowDeleting event is not being handled. I thought that was pretty explicit, so I created the event:
private void gvMainDataGrid_RowDeleting(Object sender, GridViewDeletedEventArgs e)
{
return;

Well.....that didn't work. So, I thought that maybe I needed to configure it via the actual aspx file. So, I changed
<asp:GridView ID="gvMainDataGrid" runat="server">
</asp:GridView>
to this:
<asp:GridView ID="gvMainDataGrid" runat="server" ondeleting="gvMainDataGrid_RowDeleting">
</asp:GridView>
But, no avail. I've scoured the web and tried so many combinations of capital letters and whatnot -- but no effect.

It works on Internet Explorer but I have few users who started to use apple's snow leopard and event is not at all firing on those browsers.
I believe some browsers have different JavaScript implementation

I have a GridView on my page and I have bound a custom DataSource (DataTable populated from an SQL query) within an UpdatePanel. I have set the OnRowUpdating property and create the code behind stuff as well as setting AutoGenerateEditButton to true. The problem I have is that when I click on 'Edit', then change some values then click 'Update', I can only get the old values.

All of the other posts I have read have mentioned the GridView being bound on post back or within a RowDataBound event but I'm pretty sure that I am not doing that.The RowUpdating event does fire but the value of Jockey, for example, is still the original.
