I have declared the Treeview Like below
[Code]....
and added the items to parent node and child Nodes Now how i loop through the treeview to get the checked items?May i have to find the checkbox in treeview and then loop through the treeview and find if Checkbox is checked then print the name suggest me best practice for getting checkbox checked treeview Nodes
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 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.
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?
How bind the data through checkbox if checkbox checked is true

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 have a checkbox and a textbox. When the checkbox is checked I want make the textbox required. I tried what's below but it is not working.

the problem is actually in the subject. I have custom control that uses treeview. The control is added dynamically. Nodes for this treeview are populated on demand. Treeview nodes can be checked. I recreate this control on page load event, but still CheckedNodes is empty if checked nodes were added dynamically (added on demand).
View 2 RepliesI 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.
