Even though im checking the checkbox im not the checkbox checked in code behind.
I have two checkboxes on my form.
- How can I uncheck a checkbox using client side code when the other checkbox is checked?
- Is there a way to check server side on form submission that at least one check box is checked?
I have a GridView that I was previously populating via an ObjectDataSource, and this code was working perfectly (ie, when the checkbox was checked Checkbox.Checked = true):
CODE BEHIND:
[Code]....
[Code]....
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="chkRDR1" runat="server"/>
</ItemTemplate>
</asp:TemplateField>
=========================================================================================
Dim checkbox As CheckBox = CType(row.FindControl("chkRDR1"), CheckBox)
I'm having trouble getting selected rows in asp.net. i tried to debug it and found out that the answer to "chkRow.Checked" is always false eventhough it is selected. I'm new to asp.net.here is my code.
Protected Sub btnApproveYes_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnApproveYes.Click
Dim modID As String = String.Empty
For Each row As GridViewRow In gvModule.Rows

How bind the data through checkbox if checkbox checked is true
View 3 RepliesI have an html checkbox that controls a list of checkboxes. I want this checkbox to display in a sorta "null" state where it is neither true nor false.
<HeaderTemplate>
<div style="width:90px">
Toggle:
<input id="chkAll"
onclick="javascript:SelectAllCheckboxes(this);"
runat="server" type="checkbox" />
</div>
</HeaderTemplate>
In the code I have here, I need to set the checkbox state from a database but I dont know the properties:
[Code]....
I have a CheckBox field inside a Formview.
<asp:FormView ID="_fvApplicant" runat="server" DefaultMode="Edit" OnItemDeleting="ApplicantItemDeleting" Width="100%" DataSourceID="_dsApplicant" ondatabound="ApplicantFormBound">
<asp:CheckBox ID="_chkSuitable" OnCheckedChanged="test" AutoPostBack="true" CausesValidation="true" runat="server" Checked='<%# Bind("Suitable") %>' /></td>
In my Code Behind in test method I am trying to set the checked to true, but in the ApplicantFormBound event when i debug it is never true...any reasons why? Basically I want to set the Validator to true when checked.
protected void test(object sender, EventArgs e)
{
CheckBox vld = (CheckBox)_fvApplicant.FindControl("_chkSuitable");
vld.Checked = true;
_fvApplicant.DataBind();
}
protected void ApplicantFormBound(object sender, EventArgs e)
{
var chk = (CheckBox)_fvApplicant.FindControl("_chkSuitable");
if (chk != null)

I have the following problem...
I'm developing an an asp.net 2 application in c#. This site is being built with accessibility in mind, and as such I need a to build a registration from that validates using server side scripts and
not use client side validation.I need to validate a textbox (whether any text has been entered), if a check box has been checked.
Bear in mind that I can't use any clientside code such as javascript postback that is wired into the <asp:CheckBox /> control.
I am working on building a webform in visual studio ultimate 2010. What I need the form to do, for purposes of ease of use and data integrity, I have a list of service providers that, when a visitor has subscribed to service from say, Sprint, in order for us to proceed with our business practice, we would need their Sprint PIN account. So when they check 'Sprint', a label that says Enter Sprint PIN: and a text box should appear.
Of that label and text box control, on the properties pane, i set the visible property to false, then erased that, and put it in the page load section of the C# code and erased it, since neither scenario worked. This is the current code I have, and either they appear, or are invisible, and when the check box is clicked, nothing happens...

I am using Repeater and i have checkbox in every row. I have to post all the rows to a DB Table.
The problem is:When i uncheck a row and then press the save button , all the rows are getting saved.
I checked with debugger that actually i see the checkboxes unchecked , but the debugger shows them checked.
Checkboxes have JAvascript onclick events associated with them.
[Code]....
My javascript function updates the labels on the page.My getvalues from repeater code is as follows. i am checking all the rows whether checked or unchecked.
[Code]....
why checkboxes are showing always true whereas they should have been false (as they are unchecked).
I am using following code on SelectedIndexChanged of Dropdownlist in GridView for filling txtCallCompletion.Text. When i am selecting first time it is coming correct and i am changing value of txtCallCompletion then i am selecting second checkbox then previous checked checkbox's txtCallCompletion value will be same as it is.
how to solve this issue in gridview checkbox i already checked.

I have a label and a checkbox that reside in a datagrid. When the checkbox is checked (OnCheckedChanged), I would like to send the Checkbox value and the label.text to a method. I don't have a way of retrieving the values. I've seen a lot about retrieving all of the values from a datagrid, (myDataGrid.Items), but am not sure how to get the value for a specific row in the datagrid.
View 1 RepliesI have a table with 100 cells in it (10x10)
In each cell there is a checkbox. On page load, each checkbox is checked depending on records 0-99 from a database. This works fine.
However, I want to be able to update those 100 records in the database by checking or unchecking the checkboxes.
The update process works ok as I have debugged it, but the problem seems to be that if I check a checkbox, that value (true or false) doesn't get passed to the event handler.
This is the button click event handler that I'm running right now to see if the value is being recognised:
[Code]....
If I tick checkbox zero and click the button, it still comes up as false. What I want to happen is that the DB is updated and when the page loads, the checkboxes are repopulated with the new values from the database.
I have a DropDownList for suppliers; suppliers can be active, or inactive. I have a checkbox to toggle between all suppliers, or just active suppliers.
My front code is:
[Code]....
My back code is:
[Code]....
BindDDL() also gets called in page load. The checkbox is unchecked by default, so when I first navigate to the page, only the active suppliers will be selected. When I click the checkbox, the page post posts back, but doesn't change the data in the DropDownList (still only active suppliers).
I've run through the debugger and it's hitting the right if statement, just not updating, and I don't know why. I've tried a Show all/active dropdownlist and event handlers, and neither do what I want them to do. How do I fix this?
Fix: BindDDL() method
I think this must be easy... I need to read if a certain checkbox is checked or not, but it's mandatory to me use the findcontrol.Can someone help me ? maybe it's just necessary to complete the code bellow:
Control cb = FindControl(cols[i].id_coluna.ToString());
I have tinkered with this a bit, and would like to know how to require fields based on the status of the checkbox.
The page I am referring to is located at www.libertyhtc.com/billsubmit.aspx.
Under Step 3, say, if a user checked the Television box, the textboxes for service provider, and authentication would be required. the upload file can be left blank if the user chooses to do so. This would be true of the Internet, Home Phone, and Cell Phone areas.
Now, later on, once the user clicks submit bill, I would like to have it go to a page that would bring up a page with the service agreement. The service agreement would pull data that they just put into the form before clicking that button. This step is necessary to allow the user to print out the page for their records.
Finally, there should be a button that, when clicked, will send all the data in the first form (located at www.libertyhtc.com/billsubmit.aspx) to a specified email account. I have sent data to an email before, but the code sample I used wanted the stmp details and logon information in the source code of the page, and for obvious reasons, i dont want users to know this.
