I have a checkboxlist in my asp.net page. I am adding items in it on design time. and i have a button which selects all the checkboxes inside checkboxlist. It works fine but there is another button which causes post back, and after postback, all checkboxes inside checkboxlist get unchecked and lose selection. How can I fix this ?

I got a checkboxlist in which I bind the items with data from the DB.Means the rows in my table re directly bind tochkboxlist to display as the 7 listitems in it.Together with that am binding the state also(ie,whther it is previously checked or not by the user).Now the user have the option to edit this settings by checking or unchecking the listitems in it.We need to update this in the DB accordingly.
I need to pass the Id's of the checkd items separated by a "|" along with the state 1 or 0.Meaning if the user check 1st threecheckboxes in the list my parameters shud be (userId,1|2|3,1|1|1)..I tried in the below way..
public
void UpdateNotificationSettings()
{
NotificationDO notifyDO =
new NotificationDO();

What am I missing here?
Checkbox's ID comes from Datareader.
Here is my code.
If reader2.HasRows Then
While reader2.Read
Dim jobid As String = Convert.ToString(reader2("JobTicketID"))
Dim jobtitle As String = Convert.ToString(reader2("JobNickName"))
Dim item As ListViewDataItem
For Each item In ListView1.Items
Dim jobtd As HtmlTableCell = CType(item.FindControl("jobtd"), HtmlTableCell)
Dim jobtr As HtmlTableRow = CType(item.FindControl("jobtr"), HtmlTableRow)
Dim cb2 As CheckBox = New CheckBox
cb2.ID = jobid + "cb2"
cb2.Text = jobid + IIf(jobtitle <> "", " (" + jobtitle + ")", "")
jobtd.Controls.Add(cb2)
jobtr.Visible = True
Next
End While

I want to know the selected value of the markup below. So that I can disabled a textbox, if one of the checkbox is selected.
<asp:CheckBoxList ID="ChkTest" runat="server" RepeatDirection="Horizontal" CssClass="toggleYesNo">
<asp:ListItem Value="1">Yes</asp:ListItem>
<asp:ListItem Value="0">No</asp:ListItem>
</asp:CheckBoxList>
I tried using this function it doesnot seem to work
$(document).ready(function() {
$("#<%=ChkTest.ClientID %>").click(function() {
value = $(this).val();
if(value=='1') {
$('#atextbox').attr('disabled','');
}
else {
$('#atextbox').attr('disabled','disabled');
}
});
});
I also track the output HTML but the id the CheckBoxList the assigned to a table instead.
UPDATED
<table id="ChkTest" class="toggleYesNo" border="0">
<tr>
<td><input id="ChkTest_0" type="checkbox" name="ChkTest$0" /><label for="ChkTest_0">Yes</label></td><td><input id="ChkTest_1" type="checkbox" name="ChkTest$1" /><label for="ChkTest_1">No</label></td>

how to apply background image for checkbx inside checkboxlist
View 1 RepliesI have a asp.net listbox server control that is connected to a jquery plugin that can handle a client side click event for each of the checkboxes it renders.
Whenever I click on a checkbox the click event gets triggered and I make a call to
__doPostBack("UpdatePanel1", ""); so that i can update the updatepanel and rebind the checkboxlist inside it.
is it possible to do the rebind first, and then update the updatepanel? how do i do that? because now, the rebind happens on the second time i click on the checkbox.

im learning webforms and asp.net in general and what i have so far is a formview that displays data being pulled from a sqldatasource, but i also want a checkboxlist that can be used to input information and display information. this checkboxlist is insode the formview. the problem im having is that my formview is calling a datasource with an specific stored procedure with one table and my checkboxlist needs to called another stored procedure that has a different table. formviews does not allow you to have tow different datasources so how can i make this possible? ill paste the front end code and the backend code so you guys can see what im trying to do.

I´m using a Repeater to generate Items out of a Database. Each ReapeaterItem should include an UpdatePanel, because i have to Update the Controls inside the UpdatePanel and do not want to reload the complete page. Inside these dynamically generated UpdatePanels (each RepeaterItem has one) i´m adding up to three Checkboxes dynamically (based on the Database). These Checkboxes need to fire the "CheckedChanged" event, because on some conditions i want to enable/disable/check/uncheck Checkbox1, 2 or 3 based on business logic. ... Hope you got this so far. I´m adding all Controls and have the EventHandler Added. But the generated Code does not reflect the Event Handler. I tried OnItemDataBound, OnItemCreated, PreRender, ... Events to add the Eventhandler too, but i was not able to find the CheckBox-Control with the ID.
I´m totally lost with this and on the way to use Buttons instead of Checkboxes. From what i read so far is that with Buttons i can use the CommandName from the Button and the ItemCommand-Event from the Repeater to get a workaround, but then i need to reflect the "Check" on the Page in some way. btw, every Repeater (8) sits inside an ajaxtoolkit-accordion control. Here i give you some Code:
aspx-Page
<asp:Repeater ID="RepeaterAccordionPane2" runat="server">
<ItemTemplate>
HTML Stuff<%# DataBinder.Eval(Container.DataItem, "Header")%>HTML Stuff<%# DataBinder.Eval(Container.DataItem, "Beschreibung")%></td>
<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode=Conditional>
<ContentTemplate>
</ContentTemplate>
</asp:UpdatePanel>
HTML Stuff
</ItemTemplate>
</asp:Repeater>
Here is the Page_Load Part
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
dvAlleArtikel = new System.Data.DataView(...Database...);
[... some other code here ...]
RepeaterAccordionPane2.DataSource = dvAlleArtikel;
//RepeaterAccordionPane2.ItemCreated +=new RepeaterItemEventHandler(RepeaterAccordionPane2_ItemCreated);
//RepeaterAccordionPane2.PreRender +=new EventHandler(RepeaterAccordionPane2_PreRender);

I followed your topic to select all rows with checkbox in gridview header and it is verygoodThis is code :
<script type="text/javascript"> function CheckAll(objRef) {
var grid = document.getElementById("<%=Grd_Data.ClientID%>");
var headerCheckBox = document.getElementById("ChkAll");
var inputs = grid.getElementsByTagName("input"); for (var i = 0; i < inputs.length; i++) {
if (inputs[i].type == "checkbox") { if (objRef.checked) { inputs[i].checked = true;
} else { inputs[i].checked = false; } } } }</script>
But i noticed that when i deselect a row in gridview the checkbox in header is still checked.How can i fix this problem that when i deselect one row from gridview the checkbox in grid header change to be unchecked ?
how I access /retrieve values of checkboxlist inside a repeater? My code is below..is it the same as if it was not inside a repeater? My other concern is how do I distinguish these checkboxes because basically what 's going to happen here is based on which checkbox is selected I need to query an xml file to get the location of a folder which I'm then going to zip up and allow user to download..So here's the breakdown. I have an accordion panel using jquery ui. Each panel hold a product and each product has the same checkboxes..so depending on which product the user wants to download files for which he/she will indicate by opening the accordion panel for that product and checking which checkboxes/file they want to download . So how will I know which product the user clicked the checkboxes for being that I'm using this repeater which just one ID?
[Code]....
can I still use this code or will it not work cause it's inside a repeater..also I was going to use jquery to add an onclick event to the checkbox so how can I do that now with me using this control?
