RadGrid - SelectedItems.Count = 0 in ItemCommand

Hi,

I want to delete selected item but in a particular way.
So, I created CommandItemTemplate with some Linbutton, especially DeleteButton with custom Command "DeleteSelected".

On my grid I had property to allow client select row:

<ClientSettings>

<Selecting AllowRowSelect="True"

/>

</ClientSettings>

I use event "ItemCommand" from serverside and it's correctly fired. But in this event, RadGrid.SelectedItems.Count is always 0.

if (e.CommandName == "DeleteSelected")

{

if (RadGrid.SelectedItems.Count > 0)

{

//Always 0

}

Where am I wrong ?

Couple problems (Date Range in header and binding controls in advanced forms)

I am using a Rad Scheduler in Timeline view to view active "appointments" and I have bound controls to NumberOfSlots and SlotDuration. The problem is if I show 4 slots of 1 week each the headers only show the week start (ie 4/25). Is there a way to change the headers to be a little more intuitive, like... 4/25-5/1, 5/2-5/8, 5/9-5/15?

My second problem is with trying to create an advanced edit/insert template. I have a combobox inside of a radscheduler and I would like to add a second combobox that selects types (1,2,3,4) and filter the Names combobox based on whether the relational table has an entry of type X and Name Y.

<asp:SqlDataSource runat="server"

ID="GrabScheduling"

ConnectionString="<%$ ConnectionStrings:Server %>"

SelectCommand="GetApt_By_ProjectID"

SelectCommandType="StoredProcedure"

>

<SelectParameters>

<asp:ControlParameter ControlID="ProjectStatus" Name="pstat" />

</SelectParameters>

</asp:SqlDataSource>

<Tel:RadGrid runat="server" >

<Tel:RadScheduler runat="server" ID="RadScheduler1" DataSourceID="GrabScheduling" StartInsertingInAdvancedForm="true" DataKeyField="ID" DataStartField="Start" DataEndField="End" DataSubjectField="CName" CustomAttributeNames="NameID">

<AdvancedEditTemplate>

<asp:SqlDataSource runat="server" ID="SelectAvailNames"

ConnectionString="<%$ ConnectionStrings:Server%>"

SelectCommand="Get_Name_Timeslot_Availability"

SelectCommandType="StoredProcedure"

>

<SelectParameters>

<asp:QueryStringParameter QueryStringField="PID" Name="PID" />

<asp:ControlParameter ControlID="startDate" Name="Start" />

<asp:ControlParameter ControlID="endDate" Name="End" />

</SelectParameters>

</asp:SqlDataSource>

<Tel:RadComboBox

runat="server"

ID="NameMems"

AllowCustomText="true"

DataSourceID="SelectAvailNames"

DataTextField="Name"

DataValueField="ID"

MarkFirstMatch="true"

SelectedValue='<%# Bind("NameID")%>'

>

<ItemTemplate>

<div<%# If(Eval("AlreadyScheduled"), " style=""background-color: pink;""", "")%>>

<%# Eval("Name")%>

</div>

</ItemTemplate>

</Tel:RadComboBox>

</AdvancedEditTemplate>

</Tel:RadScheduler>

So.... Yeah! This is my first post and I really tried to solve these two before coming here. I really appreciate any help, thanks!

Lightbox with images from database

I was wondering if there is any easy method to use the Lightbox control with image content stored in SQL database? I see that the server side properties only contain a URL path for file system stored images, but I would like to see an example with actual image content being pulled from the db. Maybe this could be done using RadBinaryImage? Any help would be appreciated.

Un-checked child node needs to remain un-checked upon parent node with set_checkable(false)

Hi,

I have a TriStateCheckBoxes TreeView and want to filter out nodes based on user inputs from client side. Parent nodes need to stay visible if one or more child nodes are visible, but I don't want the parents to be selectable since they are not a partial match with the user input. A problem I'm having is that as soon as set_checkable(false) is called on parent nodes whose CheckState were Indeterminate, un-checked child nodes get checked. I want those un-checked nodes to remain un-checked. For instance, in my example below, check all nodes except "Child RadTreeNode1" and perform a filter with "child" input. When the filter is done, the check box on the root becomes invisible (expected) but the "Child RadTreeNode1" node gets checked (not what I want). How can I workaround it so that the un-checked nodes remain un-checked? Please advise. Thank you.

<script type="text/javascript">

function ClientClicked(sender, args) {

var tree = $find("<%= myTree.ClientID %>");

var textbox = document.getElementById("<%= txtBox.ClientID %>");

var searchString = textbox.value;

for (var i = 0; i < tree.get_nodes().get_count() ; i++) {

filterNodes(tree.get_nodes().getNode(i), searchString);

}

function filterNodes(node, searchString) {

var hasFoundChildren = false;

for (var i = 0; i < node.get_nodes().get_count() ; i++) {

hasFoundChildren = filterNodes(node.get_nodes().getNode(i), searchString) || hasFoundChildren;

}

var returnVal;

if (node.get_text().toLowerCase().indexOf(searchString.toLowerCase()) != -1) {

node.set_visible(true);

node.set_checkable(true);

node.enable();

returnVal = true;

}

else if (hasFoundChildren) {

node.set_visible(true);

node.set_checkable(false);

returnVal = true;

}

else {

node.set_visible(false);

returnVal = false;

}

return returnVal;

}

</script>

Custom validator failure within a RadAjaxPanel

Will a standard custom validator work within a RadAjaxPanel?

I have a screen with a RadSplitter containing multiple radcombo boxes, custom validators, and the usual javascript code for the validators

Until now they've been working perfectly.

I've just enclosed the entire splitter in a RadAjaxPanel.

All the server-side code is working normally but the custom validators appear to have failed completely. The Javascript functions are not being called.

Appointment - Edit image next to delete image

In the Scheduler, when you hover your mouse over an appointment it shows a delete image. This is nice, but I want the same functionality with an edit image. I know I can implement a click or double click client event to handle editing, and in fact have already done so with double click, but to make it more clear to end users I would also like an edit image. They are also used to having this from an old scheduler control we are looking to migrate away from another vendor to use the telerik scheduler control.

I don't mind rolling my own solution, but any help you can provide if you have done this regarding css and client scripts that I can use would be great. Ultimately I think this should be built into the control itself as I can't imagine I am the only one wanting this.

Also, I know I can put my own image in an appointment template which may be what I end up having to do, but again I want it to look nice and appear right next to the delete image when you hover the mouse over the appointment.

Registered Trademark symbols are converted to the wrong symbol

When I add the code for a registered trademark symbol (®) provided by you guys at Telerik in this post http://www.telerik.com/support/kb/details/adding-special-characters-in-html-code I am getting inconsistent displays. When I enter the character code (® or ®) it instead puts in this different symbol Æ once published.

Any idea why I can't get a simple Registered Trademark symbol to appear correctly? This is very frustrating since it is a very simple and straight forward part of HTML coding. Any help would be greatly appreciated.

Thanks,
KC Painter

Node expand causes page refresh

Hello,

I'm using a radtreeview that is being populated by my database. On initial load it loads the starting options. When a node is expended the the _NodeExpand event is fired. This populates the next level of nodes. Some of these nodes have checkbox code within the html that is loaded. That all displays and works fine until I go to a different starting option node and expand it. This cases the page to reload and my checkboxes disappear but the original nodes are expanded. How can I prevent the reloading of this page so my users can open all different nodes and see the checkboxes?

Thank you
