Forms Data Controls :: Onchange To Work On Datagrid Order Form?
Jan 14, 2010
I'm having trouble generating onchange event code for a simple order form housed in a datagrid.This takes product items from sql database,whereas user can enter quantity (originally set to 25) of cards they want to order (the textbox id is txtQty). if they order 50 (so if they order 25 to 49,the price would stay the same for the lot),the subtotal for that given product will change another 15 dollars greater.,so the formula for the price wouldnt be product * price, but "if qty = qty + 25 then subtotal = price + 15".Then the button click event would add the subtotals to a grand total.
I cannot coordinate teh adequate javascript that would fit with this type of scenario,given that this is all predicated on each product coming from the database; i'm wondering if there is another good source i can be directed to that would show helper functions in the code behind or header subs to calculate the onchange (or textOnchange) event of the textbox.
<form name="mydgrid" runat="server">
<asp:DataGrid id="dgProducts" runat="server"
AutoGenerateColumns="False" CellPadding="4"

I have a Datagrid one of the colums is a checkbox and when it is selected I' m supposed to update that row. I have a button to update this outside the Datagrid. It seems to work well for the first two rows but after that meaning starting 3 to any it just doesnt update no errors but doesnt update. When I look into the id it seems to be empty.
Private Sub btnInactivateAllSelected_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnInactivateAllSelected.Click

'Variable declarations
Dim ruleID As Guid = Nothing
Dim oRule As PSXSTL.Digecenter.Rule = Nothing
Dim changetext As String = Nothing
'Start Try...Catch statement
_moduleName = "btnInactivateAllSelected_Click"
Try
For Each item As DataGridItem In GroupDataGrid.Items
If CType(item.FindControl("chkApprovalCheck"), CheckBox).Checked = True Then
ruleID = GroupDataGrid.DataKeys(CInt(item.ItemIndex))
oRule = New PSXSTL.Digecenter.Rule(DirectCast(Session("CustomerID"), Guid), ruleID)
If oRule.Complete Then
oRule.RuleStatus = False
oRule.ActiveDate = Now.ToString
changetext = "On " + Now + " " + Session("FirstName") + " " + Session("LastName") + " deactivated the Rule."
If Not oRule.ProofReviewed Then
changetext = changetext & " PDF not viewed"
End If

I am making checkbox in datagrid, no matter what I try, I cannot get the right result from checkbox. Even I check or not check the checkbox, the result is false. It is like somehow the result is always the default value of the checkbox.
Here is code:
private void OrderButton_Click(object sender, System.EventArgs e)
{
CheckBox x;
foreach ( DataGridItem dgItem in DataGrid1.Items)
{
x = (CheckBox)dgItem.FindControl("OrderCheckBox");
this.ALERT(x.Checked.ToString());
}
}
And here is my html:

Here is the situation:I have a Datagrid which is going to display a number of rows. I want to click a button on the datagrid and have the following occur
open a row underneath the row clicked, without hiding or replacing that row Open this row so that it spans all of the columns as one continuous row where i can put form fields and/or just data formatted as I would like and not just in columns.Be able to close that new row. While I do most of my work in VB.NET, don't think that is a requirement for answering this.I have managed to currently take the first column (with the "Edit" button) and when clicked to
Hide the rest of the cells in that row Expand the button column to run all the way across the table Unfortunately I loose the clicked row's data, and I've only started getting this to work so I haven't tried too much, or getting data to bind to fields "on the fly"

My forst post here + I am new to Asp.Net as well. 2nd my apologies if this question has been asked before.
Here is my problem. I am given some really abstract ASP.net pages, where I have to make a change. My change involves adding some links and on each link I have a function which is triggered when link is clicked on. This function validates some information in the form and then submits this form. This same form contains mulitple list boxes, all of them has AutoPostBack=true. The problem is when I select an item from listbox the form is submitted as I can print all the form properies on the page(all fields with their names and values) however, when I click on link and call the same forms submit(); method I dont see that happening. none of the form fields are printed out.
Now once I click on listbox and select an item after that as long as that item is selected, I can click on all links and they all call the submit() method of the form and it produces required resutls. I am really baffled as this doesnt seem correct as far as simple html is concerend.

New to MVC and jquery. I have a dropdownlist on my page and want to populate another field on the page, depending on what is selected from the dropdownlist. The data to be displayed in the other field needs to be retrieved from the database using the value of the selected item. I have found similar posts and have implemented the following, which doesnt seem to work.
jquery:
<script language="javascript" type="text/javascript" src="../../Content/Scripts/jquery-1.3.2.min.js" >
$(document).ready(function() {
$("#CourseID").onchange(function() {
var dropdownval = $("#CourseID").val();
[Code].....
I realize the action isnt correct, but at this point I can even into the action. I cant determine if the onchange is not firing or if there is some other problem.

From my testing, it appears that the order of parameters for the UpdateParameters must match both the order of the bound fields on the form (asp:Formview), and the order of the parameters in the UpdateCommand. Is that correct? If so, why do the parameters have names if all that matters is the order? I tried both asp:ControlParameter and asp:Parameter. Maybe the more relevant question is why aren't the names used instead of the order, particularly for the form order?
So, given I display the Identity field (CID), and need that for the update, I cannot get the update to work without including it in the UpdateCommand. Of course, since it is an autonumber field in Access, I cannot actually set it. So, I had to add another field to the db (lngUpdateCID) that I could set. That can't be how it has to be done, but I could not figure out another way to do this.
The relevant code is below:

In one order form, user have to input/answer about 30 questions before clicking submit button.
Sometime due to network problem, submission is failed and user need to re-input/answer all questions again.
Is it necessary to save data before submit? If yes, where to save them?

Simply put... I want to duplicate the example found at this link, in VB.net rather than C#.
[URL]
I would like the selectedvalue of the dropdown to display additional data base on its selection in multiple text boxes.
I have tried using the DropDownList OnSelectedIndexChanged property, within a DataGrid EditiItemTemplate, but I cannot retrieve data from the selection. (AutoPostBack is "True"). I can however use a button onclick event to fire a "prre-defined" selection value.
