[Solved] Opera leaves vertical gap

I have a very wide grid, which in Opera needs to have scrolling enabled

// Opera lops off Items grid

HttpBrowserCapabilities Lugs = Request.Browser;

if (Lugs.Type.StartsWith("Opera"))

{

rgItems.ClientSettings.Scrolling.AllowScroll = true;

}

(all the other browsers are fine IE, Firefox, Chrome, Safari)
there is this huge whitespace in Opera which isn't in any of the other browsers above

Navigation at client side

Hi,
I am populating my scheduler at server side using a IEnumerable collection. I am binding all the appoinments on page load. Now when I navigate in between Views(Day, Week and Month), I want the navigation to happen at client side. i.e. no postbacks should happen.

Please let me know if this is possible.

NeedDataSource always called on past back

I have a grid inside a user control. The user control is recreated on postback. After it is recreated the NeedDataSource always fires and the rebind reason is always "InitialLoad". Also, none of my command handlers are called. Am I not supposed to be recreating the control?

This is what I'm doing:

Creating the user control with the grid inside of it.
In the NeedDataSource, I bind it to the data (and I DON'T call DataBind or Rebind())
The grid shows up fine with all data in it.
Then when I press edit, it makes the fields editable.
Once I press update (which is next to "cancel"), it posts back, the user control (that contains the grid) is recreated by me in Page_Load, and NeedDataSource is called again. The rebind reason is always "InitialLoad".

Notes:

No where am I turning off view state.
I'm using telerik version 2011.2.915.40.
The only place I'm bind to the grid is in NeedDataSource.

Any idea on what may be happening? All I'm looking to do is having a grid that has items which I can edit.

Here is my grid definition:

<telerik:RadGrid ID="radGridEmails" runat="server" Skin="Transparent" AutoGenerateColumns="false">

<MasterTableView EditMode="InPlace" >

<Columns>

<telerik:GridEditCommandColumn />

<telerik:GridBoundColumn DataField="Name" HeaderText="Name" UniqueName="Name">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Email" HeaderText="Email" UniqueName="Email" >

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

More markup in the user control:

<telerik:RadAjaxManagerProxy ID="RadAjaxManager2" runat="server" >

<AjaxSettings >

<telerik:AjaxSetting AjaxControlID="radGridEmails" >

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="radGridEmails" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy>

Code in aspx Page_Load:

if (ViewState["currentlyLoadedSection"] != null)

{

panelMain.Controls.Clear();

string ctrl = (string)ViewState["currentlyLoadedSection"];

UserControl uc = (UserControl) GetControlByType(ctrl);

uc.ID = ctrl;

panelMain.Controls.Add(uc);

Trace.Write("recreated section " + ctrl);

}

Code in user control:

protected override void OnInit(EventArgs e)

{

base.OnInit(e);

radGridEmails.UpdateCommand += new Telerik.Web.UI.GridCommandEventHandler(radGridEmails_UpdateCommand);

radGridEmails.InsertCommand += new Telerik.Web.UI.GridCommandEventHandler(radGridEmails_InsertCommand);

radGridEmails.DeleteCommand += new Telerik.Web.UI.GridCommandEventHandler(radGridEmails_DeleteCommand);

radGridEmails.NeedDataSource += new Telerik.Web.UI.GridNeedDataSourceEventHandler(radGridEmails_NeedDataSource);

}

protected void radGridEmails_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

{

radGridEmails.DataSource = emailAddresses;

Trace.Write(e.RebindReason.ToString());

}

[Solved] eventArgs of a named/non Anonymous JS Function

Hi,

stupid question ... How can I get the list of arguments available in a named/non anonymous function?
For example, I'm calling onClientXXXX = "MyJS" on a Telerik Control and I'd like to know what is available in the eventArgs ?

Also, when i go in specific RadControls Documentation, sometimes I can get from the examples ... the methods on the eventArgs... eg : args..set_cancel(), args.get_checked()....etc but where do I get an exhaustive list of available methods/properties of those respective Args... I can't seem to find them.
Thanks

Problem with patched .NET Framework

On December 29 2011 a vulnerability was found in the .NET Framework (http://support.microsoft.com/kb/2638420) basically the vulnerability is related with the number of parameters that an ASP.NET application can receive, the problem is that if you have a RadGrid with more than 10 rows and 15 RadTextBox per row every request will exceed the maximum amount of parameters.

The error that I got was:
Message: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500

We can fix this issue using the information of the next link: http://support.microsoft.com/kb/2661403
To fix this issue we just need to set the maximum amount of parameters the page is allowed to get to something that we calculate covers our needs, in my case 3000:

<configuration>

<appSettings>

<add key="aspnet:MaxHttpCollectionKeys" value="3000" />

</appSettings>

</configuration>

But when tab is click; corresponding pageview will behave normally..



Note: Tabstrip is within custom control used inside RadGrid.

[Solved] Collapse onload

I have a panelbar that I am using on a masterpage. I am saving state on it so it will pass the state to the next level. My issue is, when users select the home page tab to return to the home page, I would like the panelbar to collapse. I do not want the state to stay the same. I think my goal can be accomplished by having a collapse on load for my Home masterpage. I currently use a Javascript to collapse on selecting another level 1 page. See script below. Can someone tell me how to add an additional javascript that will collapse the panelbar onload.

function collapseItem(panelbar, args)
        {
            if(args.get_item().get_items.length < 1)
            {
        for (var i=0; i < panelbar.get_items.length; i++)
        {
            panelbar.get_items[i].Collapse();
        }
        }
        }
        </script>

Ajax & URL Re-writing

I've got some controls that do ajax requests on the page, however, i've noticed that they're posting to the wrong page address.

myfirendlyurl/myunfriendlyurl.aspx

From a few searches it seems i've got to set the ajaxurl property of the rad ajax manager. Only thing is .. I can't find it. I've looked at the intellisense attributes in both aspx and the code behind file. Neither list an AjaxUrl property. what gives?

FYI i'm using this version of the controls

RadAjaxManagerProxy - error in documentation

in the 2011 Q3 documentation that is installed on my local computer during setup, I found what I am pretty sure is a typo for the RadAjaxManagerProxy.

The ASPX code has the following:

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

<script type="text/javascript">

function myUserControlClickHandler() {

$find("<%= RadAjaxManager.GetCurrent(PageClientID %>").ajaxRequest("content");

}

</script>

</telerik:RadCodeBlock>

I believe that the code in the $find has an error, and should be the following instead:

$find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>").ajaxRequest("content");

The difference is that is should be ".GetCurrent(Page).ClientID" instead of ".GetCurrent(PageClientID".

At least that is what works for me.
