I have tried to search web regarding my query but couldn't find what I actually require, I was about 70% near but couldn't achieve what i'm looking for.
To put it simple, below is my query:
I have an ASP page which has a select box (input box) in which I'm adding request numbers through SQL database.
Below are some empty text fields, check boxes.
Whenever any user selects any of the request numbers from the select box, I want to query the database and update the below text boxes and check boxes according to the request number.
I don't want user to press any button or refresh or another frame.
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.
This is my aspx code:
[Code]....
This is my checkedchanged code:
[Code]....
I am not sure why the check change is not getting trigerred. And, is this code correct for selecting only one checkbox
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'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've got a server control that renders out a series of dropdownlist and a checkbox that all have autopostback set to true. When the control renders the onchange event binding is not written out!
Controls are defined as protected, named and added to the controls collection in OnInit, and rendered via RenderControl(writer). Page.requiresPostback is also set.
ANy ideas why this might be? I'm scratching my head.
I have to create a HtmlInputText control in code and while in code set it so that it will respond to text changes purely on the client side and not generate a server side event. In an aspx page this would be done like so:
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.
I am having a DOB text box. This text box also allows to enter the date and also to pick the date using ajax CalendarExtender.
I used to set the dirty message when we edit some thing in the page.
When I enter some thing on the text box and click on the cancel button, dirty message will occur.
The problem i am facing is that, in Edit mode, I used to get all the records and assign to the text box. In that scenerio, the dirty message si automatically set since the DOB gets changes.
I have settings.aspx page. for this page, i have two functions Page_Load and OnSubmit. In Page_Load function, iam retrieving the servername from session and updating in textbox. when i enter some other server name in the textbox, and click on sumbit, it is retrieving the old one.

but iam not getting all records only single record only iam retriving
I have a search option which a person can use a multi select listbox. I have it coded so it would loop through to see if its selected or not. I also have a stored procedure where the sql statement is coded for the select statement. For some reason, its not populating my gridview. Where am I doing wrong? Below is the code and stored procedure. [Code]....
I have a page with a series of Gridviews to display summarised information. There a three Gridviews which need to be selected as criteria and then a Go Button is clicked to retrieve the info.
At the moment the information is retreived as the dropdowns are selected. Can this be stopped until the user clicks GO?
I am somewhat new at C# so forgive me if I have something listed wrong. This is what I got:
I am working on a school project designing a car dealership website. I have an inventory list that allows you to edit any car in the inventory. When you click on the edit button it takes you to the edit page and populates the controls with selections from the database. I have an options table that stores the VehicleID and Option ID. When the page loads it fills all the DropDownLists for the vehicle info with the data and selects the correct item according to the database selection but the CheckBoxList does not select the items that are on the Options table. I checked the query in SSMS and it returns the correct data. I have stepped through the method and it works till the "(currentCheckBox != null) if statement. It doesn't throw any errors but it also doesn't select items when the page renders.
I thought it might have been something with the page life cycle since databound controls don't render until the end but the DropDown's I have fill and selects the correct item according to the database.
I've created a data bound gridview to a SQL database. I am retrieving the data with a simple select for a specific date, and then populating my gridview. The one caveat is that I have added a second header row to my gridview, and then I am hiding parts of another row that was retrieved to only populate the main header row. I believe that this is causing my issue. However, when I step through the code it appears that my ids are proper (the first row has an id of 0, etc....). However, when I check the checkbox in row 4, the actual data from row 3 is being pulled out of the gridview.
I'm in the process of developing a survey system. The tables / fields that are related to my question are:
[Code]....
My issues with this way were:
1) The Data Adaptors receive ALL the records from their correspondent tables. Not a good practice, I believe.
2) If, at some point, the survey had no categories, questions or choices under its child records, an error occurs when the page tries to build the Data Relation. With the work flow I had in mind for the system, this is bound to happen becuase all the Data entry pages (Add Category, Add Question, Add Choice) will be displaying the newly-created survey in a similar fashion (at which point, the survey will have no child records and so an error would occur)
If I have the ListView on a mode which only displays data (no editing or inserting), how do I reference data in a list view item using the code behind?
In other controls I have used e.Items and e.Values, but I can't seem to work out how to do it in the listview.
For example if I wanted to set the image based on a database column (I know I can do this in the HTML but just for the purpose of the example, what would I put in place of the *** below:
I want to show a list of all the events between two dates i.e. list of events during a perticular time span. So for that I am making the user select two dates and then after he clicks the "SHOW EVENTS" button,I am trying to display the list of all the events present during that time span.
