Check/Uncheck node on ClientNodeClickedEvent

i'd like to have the user be able to click a treeviewnode, to check/uncheck the radtreeview (with checkboxes enabled).
in other words, i use the click event of the node, and
if the node is checked for that click event, uncheck it.
if the node is unchecked for that click event, check it.

this portion works to check and unchecked node, but when a checked node is selected, the node stays checked, and does not change to Unchecked.

//Changes check status of node when clicked

function ClientNodeClicked(sender, eventArgs)

{

var node = eventArgs.get_node();

if (node.checked)

{

node.set_checked(false);

}

else if (!node.checked)

{

node.check();

}

i also tried node.uncheck();
but no success.

please help to have the node unchecked on the click event, if the node is checked.

can i check a node, without checking all the child nodes?

say i have a tree with the option to check, being enabled:
Berries
--> strawberries
--> blueberries

what if i only want to select Berries, without selecting either strawberries or blueberries? the user does not now whether its strawberries or blueberries, but needs to enter that it is a Berry.

how can i allow a user to select a parent node only, without checking all childnodes?
i tried the function UpdateAllChildren which is readily used to set the checkstatus of the children, but it unchecks the parent as well.

this is what i tried

function clientNodeChecked(sender, eventArgs)

{

var node = eventArgs.get_node();

var childNodes = eventArgs.get_node().get_nodes();

var isChecked = eventArgs.get_node().get_checked();

UpdateAllChildren(childNodes, false); // i changed the parameter here to always be false so that childnodes are not checked when a parent is clicked. when a child is clicked, the parents will be set to indeterminate state as per normal procedure

//i tried setting the code here to only select node (the parent node), it checked all the child nodes

}

//checks or unchecks all nodes

function UpdateAllChildren(nodes, checked)

{

var i;

for (i=0; i<nodes.get_count(); i++)

{

if (checked)

{

nodes.getNode(i).check();

}

else

{

nodes.getNode(i).set_checked(false);

}

if (nodes.getNode(i).get_nodes().get_count()> 0)

{

UpdateAllChildren(nodes.getNode(i).get_nodes(), checked);

}

[Solved] changing fiter item texts on a specific column..

Hi All,

Is it possible to change a specific column's filter menu texts on RadGrid demo version(i am not sure if there is any difference between demo and regular version) ?

suppose that, we have four columns. three with GridBoundColumn and one for GridTemplateColumn with CheckBox (ItemTemplate).
i am writing sample code for that column, as follows...

<telerik:GridTemplateColumn UniqueName="chkBox" DataField="isActive" FilterListOptions="VaryByDataType"

DataType="System.Boolean" CurrentFilterFunction="EqualTo"

HeaderText="Is Active"

AutoPostBackOnFilter="true" ItemStyle-Width="50px" FilterControlWidth="50px">

<ItemTemplate>

<asp:CheckBox ID="CheckBox1" runat="server" OnCheckedChanged="ToggleRowSelection"

AutoPostBack="True" Checked='<%#Bind("isActive") %>' />

</ItemTemplate>

</telerik:GridTemplateColumn>

I need to change just this column's filter texts.

If i use FilterMenu.Items collection on Page_Load (or on similar event ), it affects all columns.

Do you know any solution ?

Thanks in advance...

Paging problem when deleting last item

Hi,

I have a problem with paging, when the last page has one item and I delete it, it succeeds but the grid doesn't show any items, I have to reload the page to see them. Am I missing something?

I'm generating the grid from an open access data source.

Thanks in advance

Save checkbox state

Hi,

For an application I have to save the treeview checked items state. When users navigate away from the page and they come back the state of the selection must be persisted. I try to do this to save the collection of the checked items in a cookie or a Session.Item

The Session.Item is set every time on the OnNodeCheck event.
When I come back I set the checked nodes from the Session.Item but i think every time I set a checkbox the OnNodeCheck event is fired. Is that correct? What would be the best approach to keep the Checked state in memory so I can reproduce the treeview correctly?

BR,
Marc

Sys.ScriptLoadFailedException in Production Environment

Hi there,

File Version : 2009.1.402.35 (telerik.web.ui)

I am using Telerik controls for my many clients and works fine. Recently I have deliver one of solution to my one of new client.
This application works fine on our Dev and Test server.

However, it doesn't work at client's site and throws an exception when ajax is in play. I am not sure what the problem is. We don't have really good access to client's Server. So, if you can provide precise solution, I am happy to send it to client for fixing this bug.

Thanks in advance.

[Solved] disable GridButtonColum on per-row basis?

hello,

im on an older version of RadControls for ASP.NET AJAX ("2009.2 826") but i think the answer to my question should be pretty straight-forward.

i have a RadGrid that lists items on a page. these rows include the use of a GridButtonColumn of type Delete, like so:

<Telerik:GridButtonColumn CommandName="Delete" ButtonType="LinkButton" Text="Delete" UniqueName="deleteColumn" />

... my question -- how can i disable the visibility of this column on a per-row basis, dependent on the value of another column in the grid's DataSource? some rows are something i want the user to be able to delete, some rows are not. the rows that cannot be deleted should still allow the user to edit the row via the GridEditCommandColumn we're also using.

thanks!
matt
