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 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 a check box in the grid.IF IsChecked has a value checkbox should be checked else not.Should i check the check box in the ItemDataBound event or will it get checked automatically.
<asp:DataGrid Runat="server" ID="gridProduct" AllowPaging="True">
<Columns>
<asp:TemplateColumn HeaderText="Employee Name">[code]....
i generated dynamic checkbox n placed it in table cell( <td runat='server' id="trial"></td>) ,
i am not able to check whether check is checked when i click a button.
i recieve exeception :System.NullReferenceException was unhandled by user code

finding all check boxes in asp.net grid view is checked or not.
Depending on this I have to grayed out a button...
I have to enable the button depending on all check boxes are checked..

I have Connected an XmlDtaSource to a TreeView with checkboxes.I want to populate the user permissions in that.
<asp:TreeView ID="TreeView1" runat="server" ExpandDepth="2"
ShowCheckBoxes="All" ShowLines="True">
<DataBindings>
<asp:TreeNodeBinding ValueField="Value" DataMember="menuNode" TextField="title" />
I using TreeView with ShowCheckBoxes="All" in an ASP.NET 3.5 web application and for some reason the checked nodes are not returned in order. Lets say I have nodes A,B,C and I select B and C and hit the save button and when I check the CheckedNodes property of the Treeview the checked nodes are in order (B,C). But the next time when I go back to the page and select the node A the order is being returned B,C,A. What could be the reason for this behavior?

I have treeview with checkboxes.
[Code]....
when i check Treenode with Text='Velocity', all the three child nodes will get checked. I want only the count of child checked nodes. How can be it done.
In my Treeview i have for all nodes checkboxes.
parent

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 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

How do I know which check boxes the user has checked?!
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?

View 2 RepliesI 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...

View 1 RepliesI 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.

I was trying to find out if there are any check boxes checked in the datagrid, if non of them is checked it should show me an alert to select atleast one.
My problem starts when there is paging in datagrid...
not able to check the entire datagrid at a time in itemDataBound event for the checked check boxes.
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"/>

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.
