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.
I'm trying to display a confirm message box before firing selectedIndexChanged when user change selection in the dropDownList. I was wondering if anyone would an example of how to do this.
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.

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 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.
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.
What i need is i need to bind last 10 Order in Gridview/details view with paging, and the same order detail also fetch from database and shown in another gridview.. if user click any oderNo in first Gridview/DetailView then i need to show Respective order detail in anther gridview..
without postback coz we already fetch 10 order with orderdetails from the database..and if user click next 10 orderNo using paging then again we need to load 10 orderNo with respective orderdeatils from database like this going on....as well as let me know how to take print of particular oder and order detail....?
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.
i have a form with a gridview that does the edits. I have a detailsview that does the inserts. If I test the run the form using default values as parameters the form wors fine. If I use a the hyperlinked field as below to go to the form the form does not work.It
I m trying to stop the postback causing by ddl. I have tried the following code but still pb doesnt stop:
<script type="text/javascript" language="javascript"> var ddlSubCategory = document.getElementById("ctl00_m_g_73a5a887_bd36_4a37_966a_ed640c804a84_ctl00_ctl04_ctl09_ctl00_ctl00_ctl04_ctl00_ctl00_SubCategory"); //Get this form html source ddlSubCategory.removeAttribute("onchange"); //Here "onchange" attribute causes post back </script>
I have a checkbox in gridview. I have a onclick event in which i am checking if there are more than one record selected in the gridview, i need to select only one and de-select other checkboxes.

I am not sure why the check change is not getting trigerred. And, is this code correct for selecting only one checkbox

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.
