Hello,

my Version:
Telerik ASP.NET AJAX v.2010.1.415.35

so i haven´t a property named EnableMarkMatches like in this demo
http://demos.telerik.com/aspnet-ajax/listbox/examples/functionality/keyboardsupport/defaultcs.aspx

so i can´t build the higlighting with "starts with" method.

Calling an update panel from another

Hi,

I have 2 panels in an aspx page.
Panel1 - has 1 radiobuttonlist with Yes and No as options
Panel 2 - has 2 textboxes.

I want when Yes from radiobuttonlist is selected - the panel 2 to be displayed and the same to be hdden with No is selected.

The following the code i am using in aspx page:

<telerik:RadAjaxManager ID="RadAjaxManager2" runat="server">
    <AjaxSettings>
      </telerik:AjaxSetting>
      <telerik:AjaxSetting AjaxControlID="pnlRadioButtons">
        <UpdatedControls>
          <telerik:AjaxUpdatedControl ControlID="pnlRadioButtons" />
        </UpdatedControls>
      </telerik:AjaxSetting>
      <telerik:AjaxSetting AjaxControlID="pnlMiddleData">
        <UpdatedControls>
          <telerik:AjaxUpdatedControl ControlID="pnlMiddleData" />
        </UpdatedControls>
      </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>

The following is the C# code:

protected void RadBtnSystemUser_SelectedIndexChanged(object sender, EventArgs e)
    {
        if (RadBtnSystemUser.SelectedValue.ToString() == "1")
        {
            pnlMiddleData.Visible = true;
            reqFldUserId.Enabled = true;
        }
        else
        {
            pnlMiddleData.Visible = false;
            reqFldUserId.Enabled = false;
        }
    }

This throws an error saying that since are in 2 seperate update panels an error occured.

Is this possible?
Please help.

[Solved] Hide SlidingZone Tab on load

I've been trying to have my sliding zone load with the Tab hidden. This is proving difficult. I have tried putting javascript in the page to run when the page is rendered. That throws an error though, even when I put the script at the end of the page it runs before the controls are rendered on the page and throws a script error. This also happens when I register client script block at the end of the pageload server side.

The one thing that come the closest to working is calling the javascript in the OnClientLoad event of the RadSplitter. However, this throws a javascript error which I will note below. Everything works, everything, but I cannot have a javascript error on my page for the end user.

The Error is 'Object doesn't support this property or method.'

The debugger shows the error at this code in the page:

getHandler:function(b){var a=this._getEvent(b);if(!a||a.length===0)return null;a=Array.clone(a);return function(c,d){for(var b=0,e=a.length;b<e;b++)a[b](c,d)}}

the highlighted error is at the end on

a

[b](c,d)

Clearly this is not being thrown in the javascript I am using. Here is the code I am using.

<telerik:RadSplitter

ID="RadSplitter2"

runat="server"

Height="82px"

Width="100%"

Orientation="Horizontal"

VisibleDuringInit="false"

Skin="EPSS"

EnableEmbeddedSkins="false"

OnClientLoad="javascript:TogglePaneTabVisibility('<%=SlidingPane.ClientID %>')"

>

function TogglePaneTabVisibility(panelid)

{

var slidingZone = $find("<%=szCR.ClientID %>");

var pane = slidingZone.getPaneById("<%=SlidingPane.ClientID %>");

if (pane.isTabDisplayed())

{

pane.hideTab();

}

else

{

pane.showTab();

}

Any help is greatly appreciated.

RadTextBox strange behavior after callback

This is very weird. I've got a RadTextBox that I am loading with text for client-side editing, then submitting the edited text to a database with a Callback. This works exactly once.

After the first Callback, when I use the exact same javascript function call to re-load the RadTextBox with text to edit, no text appears. However, there's no javascript error either. And the rendered HTML in the browser that defines the RadTextBox is exactly the same both before and after the Callback.

When I click submit to do a second Callback, whatever I have typed into the RadTextBox is ignored, and the value passed to the Callback is whatever was typed in the RadTextBox the first time around. It is as if, upon Callback, a new RadTextBox is being displayed which is visible to the browser, but not to the DOM. And meanwhile the old RadTextBox is still visible to the DOM, but invisible to the browser.

What the heck is going on?

Thanks,

Jesse

How to set pageview to a tab using client method

Hello team,

How to set pageview to a tab using client method?
I added a tab and a pageview with client method, but when I click this new tab, the new pageview can not be shown.I think it's because of that I didn't set the pageview to tab, but I don't know how to achieve it with client side method, it seems server side has a method ,but client side not.

Below is the function which I use:

             var tabStrip = $find("<%= RadTabStrip1.ClientID %>");
             var tab = new Telerik.Web.UI.RadTab();
             tab.set_text("New Tab");
             tabStrip.trackChanges();
             tabStrip.get_tabs().add(tab);
             tabStrip.commitChanges();

             var multiPage = $find("<%=RadMultiPage1.ClientID %>");
             multiPage.trackChanges();
             var pageView = new Telerik.Web.UI.RadPageView();

             multiPage.get_pageViews().add(pageView);
             pageView.get_element().innerHTML = "<iframe src='http://www.google.com' width='100%' height='600px'>";
             multiPage.commitChanges();

thanks

Enable Controls in UserControl

Hi,

I have a page with several UserControls on it. Each Control Contains Dropdownlists and Textboxes.
When a user enters the page all Controls on it are disabled and the user has to press a button to switch all controls in edit mode.
To achieve this, every Usercontrol has an Enable method which is called in the edit button click method.

With RadAjaxManager I found no way to implement this. I can enable Controls that are placed directly on the page, but how can I enable the Usercontrols? The enable method is called but the Controls are not rendered because I cannot add a usercontrol to the RadAjaxManager. Is there a way to solve my problem?

Thanks in advance.

How does custom filtering work in a RadGrid

Hello,

I am using RadControls for ASP.NET AJAX 2009.1.527.20 and I have a RadGrid that requires some custom filtering.

For the first custom filter, I want a RadComboBox to drop down with a CheckBoxList. Each item in the CheckBoxList contains a CheckBox, an Image, and a Description. Then below that I would like "OK" and "Cancel" buttons. OK would apply the filter, and Cancel would just close the RadComboBox dropdown and not affect the RadGrid.

For the next custom filter, I have 5 columns of integers. I want one RadComboBox to drop down with a CheckBoxList. Each item in the CheckBoxList contains a CheckBox and a Description. Then below that I would like "OK" and "Cancel" buttons. OK would apply the filter, and Cancel would just close the RadComboBox dropdown and not affect the RadGrid.

I have (sort of) been able to create the <FilterTemplate> for each of these, but I do not know how to do a few things:

How do I add the "OK" and "Cancel" buttons to the template?
How do I apply the results of the CheckBoxes in the CheckBoxList to the RadGrid filter functionality?

I have provided a sample VS 2010 web application that demonstrates what I have and want. In this sample, I am using an XmlDataSource so I can provide sample data. In my real application, I am binding the RadGrid using the OnNeedDataSource event.

Set defualt drop down values in Edit form

Hi

i am new to telerik controls but enjoying working on these controls.

during the development i stuck at a point, where i need to set default dropdown values in edit form. Here is the sample code

<label for='<%= PriorityDropDown.ClientID %>'>

Priority:</label><%--

Leaving a newline here will affect the layout, so we use a comment instead.

--%>

<telerik:RadComboBox runat="server" ID="PriorityDropDown" Skin='<%# Owner.Skin %>' Width="100px" AutoPostBack="true">

<Items>

<telerik:RadComboBoxItem Text="Low" Value="Low" Selected='<%# Convert.ToBoolean((Convert.ToString(Eval("Priority")) == "Low")) %> ' />

<telerik:RadComboBoxItem Text="High" Value="High" Selected='<%# Convert.ToBoolean((Convert.ToString(Eval("Priority")) == "High")) %> ' />
