Web Forms :: Java Script - Check If More Than One Checkboxs Checked

Mar 16, 2011 01:15 PM

I have a web form with a gridview control on it. The GridView has a column of check boxes. Before the web form closes I need to check if more than one check box was checked. If more than one check box was checked, then I need to display a popup message box informing the user that only one check box should be checked? I need to check to see if more than one check box was checked, when a "Submit" button on the form is pressed.

How can this be done using Asp.net/C# and Java Script? I know how to iterate through rows of a Grid control so I can do that in the C# code. But how to keep the web form open before I iterate through the rows, I don't know?

Forms Data Controls :: Allow Only One Check Box To Be Checked In The GridView?

Nov 16, 2010 09:46 PM

I have a gridview that returns several records for the same user and each record has a column with a check box. I need to allow the user to choose only one to check. Also one check box is always supposed to be checked. What is the best way to do it? I was thinking of writing a stored procedure that checks if only one is checked, and then returns true or false. I think there is a more efficient way to do it...

Forms Data Controls :: Keeping Check Boxes Checked When Sorting GridView?

Jul 25, 2008 07:17 PM

I've got two columns of check boxes in a GridView. The problem I'm having is that check boxes that are checked become unchecked when the GridView is sorted.

Is it even possible to keep the check boxes in each row checked when the GridView is sorted? I was thinking they would stay checked because I have Enable ViewState set to true.

VS 2005 Unable To Check The Checked Value Of A Dynamic Checkbox Within A Gridview?

Feb 17th, 2010, 01:49 PM

I can't seem to check the checked value of a dynamic checkbox within a gridview. I've tried dozens of ways to test the checkbox's checked value, but it still returns false, when it should return true. If I change the checked value to true in the ASPX web page, then it will return true, even when it should return false. Any ideas? I've tried many different ways of checking the checkbox value including the one below.

MailingLabels.aspx

Code:
<asp:GridView ID="GridView" runat="server" AutoGenerateColumns="False" DataKeyNames="NewClientID">
<Columns>
<asp:BoundField DataField="NewClientID" InsertVisible="false" />

JavaScript - Check If A Checkbox Is Checked In A Group Of Checkboxes In Clientside?

Apr 3 at 11:31

note that the scenario is ASP.NET Webforms + Master - Content page which mess up the ids.

I have, say, three checkboxes

<asp:CheckBox ID="chkConsultantQuality" runat="server"
CssClass="company"/>
<asp:CheckBox ID="chkConsultantEnvironment" runat="server"
CssClass="company"/>
<asp:CheckBox ID="chkConsultantSafety" runat="server"
CssClass="company"/>

I would like to make a div id="CompanyPanel" on click event of each checkbox according to the following condition

visible if any of the checkboxes are checked.

hidden if all of the checkboxes are unchecked.

I am planning to use jQuery since I am selecting by class name. I could do it with jQuery.each on the class='company' by checking each for a checked flag.

C# - How To Get Multiple Selections From .NET CheckBoxs

Feb 1 at 18:24

This seems like it should be prettty easy - but I just can't get it to work!I have an enum in my model, which I want to display as a list of checkboxes. The user can select multiple checkboxes, and I want to save this in the database.

So the enum is like so (approx 20 elements unabridged):

public enum ReferrerType
{
[Description("No Data")]
NoData = 9999,[code]....

And it doesn't work! I guess I'm missing something obvious, but I can't work out what. There are no errors - just an empty database table where referrers should be.

Java Can Store Procedures As Java .Net Interop

Jul 5 10 at 6:14

I'm looking for a way to access a Java API from both a Java console application and an ASP.Net application.In short my Java API exposes a series of methods for dealing with invoices. All of these methods are essentially commands e.g.

GenerateAllInvocies
GenerateInvoiceNumber
PrintAllInvoices
PrintInvoiceNumber

All methods will interact with the database. I had believed Web Services was going to be my means for interop. But I have since been made aware of Java Stored Procedures in Oracle.

TreeView Nodes Always Have Checked = True On Postback Even When Not Checked In UI

Mar 15 10 at 1:07

I have a treeview in my .aspx: <asp:TreeView ID="tvDocCatAndType" runat="server" /> Not much else going on in the page -- two <asp:LinkButtons> and one <asp:Label>; the page is a child of a master page, so these controls are within a <asp:Content> control. I populate the treeview in code -- just 3 node levels, including the root node. All nodes have checkboxes, and I initialize all node.Checked to true. I have some Javascript to do the usual check/uncheck up and down the tree as parent and child node checkboxes are toggled.

No matter how many checkboxes I clear in the UI, on postback every single node has node.Checked = true regardless of the state of the checkbox in the UI. This is not the first time I've used a treeview, but I've never had this problem before. I created this page by light adaptation of an earlier project that works fine.
