Clientside. get_text() is returning empty string

Hi,

I'm trying to get my radcombobox (populated with checkboxes) to show what items are selected. Its similar to this demo:
http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/templates/defaultcs.aspx

However, my js code (copied from the above is simply returning empty strings with the .get_text() method.

Can anyone shed some light on why its returning nothing?

<telerik:RadComboBox ID="RadComboBox_User_Type" runat="server" EmptyMessage="Select Users" HighlightTemplatedItems="true"

AllowCustomText="true" Width="225px">

<Items>

<telerik:RadComboBoxItem

ImagePath="../Images/OnTime_Fkeys/Access Control.png"

Text_="Employee">

</telerik:RadComboBoxItem>

<telerik:RadComboBoxItem

ImagePath="../Images/OnTime_Fkeys/Access Control.png"

Text_="Visitor">

</telerik:RadComboBoxItem>

</Items>

<ItemTemplate>

<div onclick="StopPropagation(event)" style="vertical-align: middle">

<asp:CheckBox runat="server" ID="chk1" Checked="false"/>

<asp:Label runat="server" ID="Label1" AssociatedControlID="chk1">

<img src='<%# DataBinder.Eval(Container, "Attributes['ImagePath']") %>' alt="" style="vertical-align:text-top"/>

<%# DataBinder.Eval(Container, "Attributes['Text_']") %>

</asp:Label>

</div>

</ItemTemplate>

</telerik:RadComboBox>

protected void Page_Load(object sender, EventArgs e)

{

String script1 = "" +

"function StopPropagation(e) " +

"{" +

"e.cancelBubble = true;" +

"if (e.stopPropagation) " +

"{" +

"e.stopPropagation();" +

"}" +

"}";

ScriptManager.RegisterStartupScript(Page, Page.GetType(), "LMP_Stop_Prop", script1, true);

ClientScript.RegisterClientScriptBlock(Page.GetType(),"324nvik",

"<script src=\"../Javascript/Live_Monitor/Live_Monitor.js\" type=\"text/javascript\"></script>");

for (int i = 0; i < RadComboBox_User_Type.Items.Count; i++)

{

RadComboBox_User_Type.Items[i].DataBind();

}

foreach (RadComboBoxItem item in RadComboBox_User_Type.Items)

{

CheckBox chk = (CheckBox)item.FindControl("chk1");

chk.Attributes.Add("onclick", "onCheckBoxClick(this)");

}

Live_Monitor.js

function onCheckBoxClick(chk) {

var combo = $find('RadComboBox_User_Type');

var text = "";

var values = "";

var items = combo.get_items();

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

var item = items.getItem(i);

var chk1 = $get("RadComboBox_User_Type" + "_i" + i + "_chk1");

if (chk1.checked) {

text += item.get_text() + ",";

values += item.get_value() + ",";

}

text = removeLastComma(text);

values = removeLastComma(values);

if (text.length > 0) {

combo.set_text(text);

}

else {

combo.set_text("Select Users");

}

function removeLastComma(str) {

return str.replace(/,$/, "");

}

Anyone any ideas????

Thanks,

Sunny

Drag to Grid and get position

I have a treeview that the user can drag items from and drop them on a grid. Currently the dropped items go to the bottom of the grid. Is there a way I can get the row that the user dropped the items on?

The method that handles the drop is :

protected void tvReportColumn_HandleDrop(object sender, RadTreeNodeDragDropEventArgs e)

{

RadTreeNode sourceNode = e.SourceDragNode;

RadTreeNode destNode = e.DestDragNode;

if ((e.HtmlElementID == RadGrid1.ClientID))

{

foreach (RadTreeNode node in e.DraggedNodes)

{

AddRowToGrid(node);

}

RadGrid1.Rebind();

}

Speed up filtering without rebind ?

Hi,

I don't understant why I have to do a rebind() after apply a filter.

Is there an other way to to this in order to speed the display ?

At init, the user have all datas. So they must be in memory ?
If I put then a filter I have to do a rebind in order to apply it and so, redownload datas....

Is there a way to keep radgrid data in memory (table ?) and then ask to the client to filter them ?

Thanks

Using Grid to Simulate DataList

Hi:

This is my first try with Telerik controls, so please forgive me if I seem ignorant. I am trying to use the RadGrid to create a DataList-type look. I follow the example "Grid / ListView/DataList View" (http://demos.telerik.com/aspnet-ajax/grid/examples/programming/listview/defaultcs.aspx) from the demos, and I successfully displayed a grid. It looks rather odd, though, with one cell at the top of the form, then the "page counter control", then eleven cells showing below. (See the attachment.) Does anyone know what's happening here? Thanks!

Background Color Behavior

I notice that setting the background color of the RadListBox does not actually change the background color within the list area of the listbox. The background color is only changed in the button area which is not the desired behavior. I have controls on a web form and would like them all to have a consistent background color, but I don't seem to be able to achieve that just yet.

Using IE 8 and IE 8 Compatibility Mode for IE 7.

Memory Leaks???

Is it possible that there is some kind of memory leak in the latest build? I never had this problem before I installed the Telerik controls, but in the past week, I keep getting these types of messages and I need to restart Visual Studio 2010. I'm running VS 2010 on Windows 7. I am building an ASP.NET 4.0 Ajax application.

Error 23 Metadata file 'c:\Program Files\Telerik\RadControls for ASP.NET AJAX Q1 2011\Bin40\Telerik.Web.UI.dll' could not be opened -- 'Not enough storage is available to process this command. ' CreativeAffairsWebApp

HELP?!

Thanks

Need help with Grid Scrollbar and Browser Scrollbar

Hi all,

I have a grid with scrolling enabled. The grid has a width of 877px and a height of 475px.

Now I just noticed that in addition to the grid scrollbar there's a vertical scrollbar in the browser as well. I don't need that scrollbar because when I scroll down I just get a blank (in my case: black) page.
How can I remove the browser scrollbar?

Please see attached image.

Any tips?

Thanks!
