Jquery Dialog Interferes With Input Checkbox Checked Property - Always False

Jan 15, 2010

I came across the following given a page containing

<div id='test'>
<input type='checkbox' id='ch1' name='ch1' runat=server />
<input type="button" id="view_test" />

and the following jquery code to show this div in a dialog

$("#view_test").click(function() {
$("#test").dialog({ show: 'slide', width: 600, title: 'View Check' });

If view_test button was clicked, initializing the dialog, before the form post backs the checkbox ch1.Checked property in .Net is always False. However if you just postback without initializing the dialog it works as expected.

JQuery :: Checkbox Click Event Problems When Using JQuery Safari Checkbox Plugin?

Nov 26, 2010

my page are 1 checkbox and 1 hidden label and 1 hidden panel. With the help of forum member raghav_khunger I've managed to write the code which shows panel and label when checkBox is checked. I've also added the code which is checking on every page post back the status of checkbox and hide/show panel and label appropriately. This is working fine.However when I add jQuery Safari checkbox plugin [URL] problems appear.

Looks like the code which is handling click event is doing reverse thing: when panel and label should be hidden are shown. I can change this but then there would be problems because of the second part of the code which is checking checkbox on page load. So when I check the checkbox nothing happens. I must uncheck it and label and panel appears. But if panel is uncheck the label and panel would be hidden because on next page load (when user clicks button next).As I said before the same code is working fine and it's test in all browsers (IE,FF,O,S,C). Maybe there is problem with checkbox plugin since it's in beta version.

JQuery :: Adding Hover Effect To Checkbox (fancy Checkbox Plugin)?

Nov 12, 2010

I had problems with jQuery fancy checkbox plugin [URL]

However after that I want to "combine" 2 plugins, the one mentioned in first post:


and this one ("Safari"):


So I've changed the picture of checkbox and wanted to add hover effects as it is shown in second link (according to state of checkbox).

However since I'm quite noob with jQuery (and JS) the thing only works fine on "default" mode, when checkbox is not selected or checked on page load.

JQuery Incrementally Count Selected Checkbox And Deselected Checkbox?

Jan 27, 2010

I have an ASP.NET web form that has 6 checkbox. 1 checkbox is to call a Function to select all checkbox and show the message "You have selected" 6 "items" (in this case, 6 checkbox). If a user doesn't select the Select All checkbox, they can select or deselect other checkbox individually and the message will be "You have selected" # "items" I'm trying to do this in jQuery, but it's not working yet. Here's the script:


The CSS class CheckBoxClass is not with the HTML input, that's why I'm looking for checkbox Id instead of checkbox class.

C# - Sort Checkbox List On Basis Of Checked Property

Jan 14, 2010

I have a check-box-List which I bind to a master dataTable(DTA)... I have another dataTable (DTB) which has the values that needs to checked in the check-box-List... So I loop through all items in the check-box-list to see if it exists in the DTB and set checked = true for those items that exists. Now I want to show the checked items first in the Check-box-list box and the unchecked items below that. Is there any way I can do it... A similar solution for List-Box could also be helpful. A Javascript hint is welcome too.

Gridview - Toggle Checked Property Of A Data Bound Checkbox?

Aug 9, 2010

I have a GridView control that has one column of checkboxes set up like this:

<asp:CheckBox ID="RowCheckBox" runat="server" Enabled="false" Checked='<%# (bool)DataBinder.Eval(Container.DataItem ,"Associated") %>'/>

Then when the user clicks an Edit button I run a script that enables all the checkboxes (which works fine), and then when the user then clicks on a checkbox the tick is appearing or disappearing as it should.

The problem I'm having is that when I try to read the value of the checkbox from the codebehind:

CheckBox checkBox = (CheckBox) row.FindControl("RowCheckBox");
bool checked = checkBox.Checked;

If the value bound to it was true then checked is still true, no matter if it was toggled or not.

Edit: Corrected a spelling mistake. Question still stands though...

Forms Data Controls :: Cannot Assign Values To Checked Property Of Checkbox At Runtime

Apr 22, 2010

I have a ASP.Net page that has a gridview control. This gridView control has a checkbox controls. I would like to assign a boolean value from a database field to the Checked property- Checked='<%# Bind("RESULTS") %>'.

When page loads,I get error - Specified cast is invalid!

The code is as follows...

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="dsResults"
BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px"
CellPadding="3" OnRowUpdated="GridView1_RowUpdated">
<asp:TemplateField HeaderText="COMPLIANT" SortExpression="RESULTS">
<asp:CheckBox ID="CheckBox2" runat="server" Checked='<%# Bind("RESULTS") %>' />
<asp:CheckBox ID="CheckBox1" runat="server" Checked='<%# Bind("RESULTS") %>'
Enabled="False" />

Note: If a constant value is passed at design time it works fine. But i want to assign the value at runtime using Bind.

Environment details: VS 2008, ASP.NET 2.0 and .Net Framework 3.0 & C# language.

I tried returning values like 0s and 1s, Ys and Ns and True and False from a database field. But i still get the above mentioned error.

I tried retreving the value in OnRowDataBound event using Eval, since Bind is not available in code behind. But it would make the field readonly and i cannot edit and update the Results field.

Even though there is a value returned by the query why does the Checkbox does not assign the value using <%# Bind("Results") %> to Checked property instead throws error - Specified cast is invalid.

how i can edit and update Checkbox.

where did the Bind method of ASP.Net 1.x is moved? How can i use Bind in code behind of ASP.Net 2.0?When i type DataBinder the intellisense shows Eval and other stuff but i don't see Bind that would solve the problem of two- way binding.
