Web Forms :: Java Script - Check If More Than One Checkboxs Checked
Mar 16, 2011
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?

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...

I have a data grid and inside that datagrid check box and created using template field.
How can I check that a row in datagrid (not grid view) is checked or not.
For gridview we can use the below in codbehind file,
Boolean isChecked = ((CheckBox)(Row.FindControl("chkDelete"))).Checked;
For datagrid how to achieve this...
My aspx code is
<asp:DataGrid ID="dg1" runat="server">
<Columns>
<asp:TemplateColumn HeaderText="select">
<ItemTemplate>
<asp:CheckBox runat="server" ID="chkD" />
</ItemTemplate>
</asp:TemplateColumn>

I have a asp.net treeview control that I need to be able to set a parent node to partially checked to show that child nodes are checked. Basically I need a 3 state or multi-state checkbox. All I can see from looking through the code is ways to set checked true or false.

I have group of radio buttons, each group ranges from 5 - 27 radiobuttons. And if any radio button in a group is checked I store 1 in db else I store 0. Now I'm checking each radiobutton using if loop to see if they are checked and set database value. I'm also trying to use the code below. Is there a good/better approach to check if they are checked or not?Current code:
'rname is radiobutton prefix for a given group
'cnt is number of radiobuttons in the group
Private Function RadioIsChecked(ByVal rname As String, ByVal cnt As Integer) As Integer
[code]...

I generate my check boxes dynamically:
for (int i = 0; i < dtCommon.Count; i++)
{
CheckBox newBox = new CheckBox();
newBox.Text = dtCommon[i].userName; [code]...
And when the save button is pressed I call this function:
protected void SaveUsers(object sender, EventArgs e)
{
}
How do I know which check boxes the user has checked?!

I need to know how to see if a Radio Button is checked or not based on the posted data.

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.

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

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.
