Find and select a node in TreeView

Hello,
i make a RadTreeView so:

<telerik:RadTreeView ID="RadTreeView1" Runat="server" DataFieldID="playerID"

DataFieldParentID="parentID" DataSourceID="ObjectDataSource1"

DataTextField="playerName" DataValueField="Route"

onnodedatabound="RadTreeView1_NodeDataBound"

Width="100%" oncontextmenuitemclick="RadTreeView1_ContextMenuItemClick">

It works fine.
playerID - Primary key
parentID - for TreeView
playerName - String
Route - a value between 1 to 4 (1-Main, 2-Partial, ...)

Once a new record is inserted into the database, I get back the new playerID.

PlayerBLL players = new PlayerBLL();

string text = SaveSQL.GetSaveSql(txtCreateMainRouteName.Text.Trim());

if (Page.IsValid)

{

PlayerID = players.InsertRouteAndStation(text, 1, null);

RadTreeView1.DataSourceID = "ObjectDataSource1";

RadTreeView1.DataBind();

}

How can i select the new Node in the TreeView with the new playerID?

Best regards
Reiner

Nodes not expanding IE8 ONLY.

I'm using Telerik 2010.1.519.40 and webservices to populate a radtreeview. However, in IE8 when I get a large amount of nodes the treeview will not render out the nodes.

Here is aspx file:

<telerik:RadTreeView ID="tvConfigArchive" runat="server" Skin="Vista" CheckBoxes="true">
<CollapseAnimation Duration="100" Type="OutQuint" />
<ExpandAnimation Duration="100" Type="OutQuart" />
<WebServiceSettings Path="mws.asmx" Method="PopulateNodes" />
</telerik:RadTreeView>

Once again, everything works fine in IE7,IE9,Chrome,Safari,etc...ONLY IE8 doesn't work?

Any ideas?

Trying to figure out how to use?

I am bulding a upload page, but I am confused as to the proper way to handle the contols.
I dragged the Asyncupload control into my area on my page. When I do that it looks as though I also need to
Add RadAjaxManager
Add RadScriptManager
Add RadStyleSheetManager
Add ScriptManager

When I put either of the the scriptManagers on the page I get an error that there is already a ScriptManager on the page. And there is, it is used by the Tabstrip that I am using for navigation.

I add the other two managers and they don't seem to do anything.
I then add one of the Progress managers and it doesn't seem to do anything either.
The last control I have is the Submit button for Postback, when pressed the screen goes blank and the file selected goes
away with out any indication that an upload occured. Since I am doing this all on my Laptop, where should I look for the uploaded file.

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>
