How To Prevent AutoPostBack When DropDownlist Is Selected Using JQuery

Jul 21, 2010

I want to show a confirm dialog when the user selects an item in a DropDownList. If the user presses "Cancel", I want to stop the postback. Here is the function I add to the onchange event:

function imitateConfirmUnload(event) {
if (window.onbeforeunload = null)
return true;

return confirm("Are you sure you want to navigate away from this page?

You have unsaved changes

Press OK to continue or Cancel to stay on the current page.");
}

And this is the relevant bit of code in my startup script to add the handler to the event:

[code]...

The problem is that the postback occurs even if the user selects "Cancel". If I move the handler on to the click event, it works. But it feels clunky to me.

Edit

Correction: it doesn't work onclick, because the dialog prevents selection, so when the user selects OK, no change has taken place, and no postback when you want it!

Edit 2

The DropDownList is inside an UpdatePanel so that may affect behavior.

Web Forms :: Dynamically Populated Listbox Always Return Selected Items As False?

Mar 10, 2011

I have the following code which simply gets data from a table and populates the questions_lb listbox with items. I have a button on the page, which when clicked, should write (on submit) the selected state of each of the items. The code below writes the text values of each of the items fine however it always writes the li.Selected as False even though i have selected items from the list. Note that you can select Multiple items from the list. Does anyone have a clue why its not writing 'True' for an item that is selected on submit?

ADO.NET :: Validating DropDownList Populated With Data From SQL DataTable

Dec 30, 2010

i have one simple question; do I have to... or is there any need to validate value from DropDownLists that are populated from SQL Datatables. I know how to validate them, but I am just concerned about potential SQL Injection, because those DropDownLists are going to be "Input fields" for a new Datatable, and insted of using TextBoxes, user will choose values from those DDL's and Submit them (INSERT INTO) to SQL Datatable. Is there a way for a "hacker" to insert his item value into DropDownList. I hop You understand what I mean!?

Web Forms :: Getting A Dropdownlist Populated When Binding To Datatable

Aug 10, 2010

I have 2 dropdown lists on a WebForm. One of them is populated in the page's Page_Load event. This oneworks fine with the following code.

[Code]....

Then, after a value is selected from this list and a date is selected from a DateTime picker, then I click a button which is supposed to populate the 2nd dropdownlist. In the debugger in the button's click event I can see that the dataset is being populated with data, but then the list is never populated after the DataBind() method is run. Here is code from the button's click event.

Web Forms :: DropDownList Populated With SQL Stored Procedure

Mar 23, 2010

I have a DropDownList populated with a SQL Stored Procedure. On the page, there is also a button that when pressed, processes the contents of the dropdownlist. I would then like the dropdownlist to automatically remove the selection, and if there is nothing left in the dropdownlist, I would also like the button to be disabled.

Web Forms :: Dynamically Populated DropDownList Not Working

Jun 3, 2010

I have two drop down lists on my page. One (DropDownList A) has the values preset by me. The other (DropDownList B) has its values filled by a database query if a button is pressed. Each of them have AutoPostBack set to true. Each of them have corresponding onselectedindexchanged functions. DropDownList A works fine. When I change it, I want it to turn itself invisible. It does. DropwDownList B is not working. When I select something, it does the postback but the selected item is reset and the onselectedindexchanged function is never called. I feel like this is a problem I've solved in the past, but it's been 3 years since I programmed ASP.NET. All this is done in C# by the way.

Web Forms :: Dynamically Populated DropdownList Value Not Seen When Button Pressed?

Sep 27, 2010

Sample Code.
<asp:DropDownList ID="MediaTypeDDL" Width="306px" ToolTip="Select Media Type" runat="server"></asp:DropDownList>
<asp:DropDownList ID="MediaFormatDDL" Width="306px" ToolTip="Select Media Format" runat="server"> </asp:DropDownList
<asp:Button
ID="btnUpload"
runat="server"
OnClick="btnUpload_Click"
Text="Upload"
/><br
/>
protected void btnUpload_Click(object sender, EventArgs e)
{
String strMediaFormat = MediaFormatDDL.SelectedItem.ToString(); // Not seeing value here!
}

Item Selected in MediaTypeDDL determines values in MediaFormatDDL. I'm using Javascript to populate MediaFormatDDL. This is working. I now select the item I want from MediaFormatDDL. That works The problem I'm seeing occurs when I press the button to save the values from
the screen. I don't see the Item I selected from MediaTypeDDL. All the other fields are okay. This must be someThing simple, but I'm not seeing it.

Web Forms :: Dropdownlist Doesn't Work If It's Populated With Only One Record?

Jun 29, 2010

I have a dynamic dropdown that is populated from sql. The user is supposed to select an option from the dropdown, then click a search button on the form to return some results based on that selection. It works fine if the dropdown gets populated with more than one record. However, if only one record is returned, that one record can't be selected. Whether you select it or just leave it alone since it's the only one, when you click the form button (search button), no results are returned b/c the dropdown selection must not be actually selected.

I've included the relevant code below. First the DDL, then the datasource, and finally the C# code in the if (!Page.IsPostBack)

ASP.NET Validation Issue - DropDownList Being Populated Dynamically On Client?

Apr 28, 2010

I'm populating a DropDownList using JS on the client and validating with a RequiredFieldValidator.This works fine on the client but the Page.IsValid consistently comes back false on the server.Is this because the selected value wasn't in the DropDownList when it was first served to the page?What's the easiest way around this? (I need to leave server validation turned on)

Gridview SQL Parameter Null From Javascript / Ajax Populated Dropdownlist

Sep 7, 2010

My issue is similar to [URL] how-to-use-the-value-of-a-selected-value-from-a-dropdownlist-populated-with-ajax but I am using ASP.NET, not PHP. I have a dropdownlist that is populated by another dropdownlist's current value through ajax. So if DDL A is 'NY', DDL B is populated with different data relating to 'NY'. I need that data to be posted back to the server because this affects an SQLDataSource parameter. However, as far as I can tell, the value is always null after postback resulting in the gridview to be empty.

Selecting Radiobuttons Populated Within Asp.net RadioButtonList With JQuery

May 21, 2010

I have been tinkering around with what should seem a pretty straight forward task even for a jQuery newb as myself.
I have a radiobuttonlist control bound to a collection:

<asp:RadioButtonList ID="radBtnLstPackageSelector" runat="server"
CssClass="PackageS">
</asp:RadioButtonList>

My form does have several other controls of the same type; Now, the challenge is to select and wire up a on Click event for every radiobutton from the radBtnLstPackageSelector.I have tried several approaches such as:

var results1 = $(".PackageS").children("input");
var results1 = $(".PackageS").children("input[type=radiobutton");
var results1 = $("table.PackageS > input[type=radiobutton");

Forms Data Controls :: Dynamically Populated Dropdownlist Inside Gridview

Mar 28, 2011

I have a gridview which contains a templatefield. Inside this is an ImageButton and a dropdownlist. This is all created in the aspx page, although the ddl list items are populated in the RowDataBound event in the vb page. When i change the selected item in the drop down list and hit the imagebutton, the selected item is not maintained after postback. Instead the first record is displayed in the dropdownlist. I have wrapped an If Not Page.IsPostback around the datasource and databind's but this doesn't help. I have tried enabling viewstate in all areas on the page too, but still nothing. The list items for the ddl must be created on RowDataBound also. As far as I am aware, my ddl is not really dynamic, its just the list items which I add in the code behind which are classed as dynamic.
