Hi,

I have a scenario where a treeview is a dynamically populated user control placed on to a masterpage.
On the click of a node, content holder on right loads up a new page
1. Tree state should be maintained in between pages
2. Whole master page should not refresh

Please advice.

PanelBar Expand/Collapse Buttons No Server-Side Event

I have a PanelBar that I dynamically load data in the ItemTemplates when the user expands the PanelBarItem. This was working fine until the new skins came out that added the expand/collapse button to the PanelBarItems. It doesn't seem that a Server-Side event gets fired when this button is used. I was triggering off of the ItemClick event to perform my databinding, but this no longer works. Are there any suggestions on how to handle the action of a user clicking on this button?

TIA

RadTextbox scrolls while typing.

I have a RadTextBox defined like this:

<telerik:RadTextBox ID="newNoteTextArea" Runat="server" EmptyMessage="Enter new note here." Skin="Office2007" TextMode="MultiLine" Rows="4" width="99%" ShowButton="false" style="border: none;" ValidationGroup="undr_AddNote" MaxLength="2000000" ></telerik:RadTextBox>

When the user types a lot of text into the RadTextbox, the texbox will scroll back toward the top of the textbox and bounce back between the top and the typing line in-between typing. This is happening in IE7, but dos not seem to in Chrome. I have not tested Firefox or any other browsers. I have confirmed that this same thing happens in the online demo found here: http://demos.telerik.com/aspnet-ajax/input/examples/radtextbox/firstlook/defaultcs.aspx

To see it copy this into the multi-line input:

;sdlgj s;lkfjg ;slkgj;lskgj;lksdfg;skfg;lsfjg;sfgsfjglksfjd;kf;lksjd ; dfgks dfg;lksj dfg;jsf ;lksdf g;slkfg ;slkgj s;lfk ;sdlgj s;lkfjg ;slkgj;lskgj;lksdfg;skfg;lsfjg;sfgsfjglksfjd;kf;lksjd ; dfgks dfg;lksj dfg;jsf ;lksdf g;slkfg ;slkgj s;lfk;sdlgj s;lkfjg ;slkgj;lskgj;lksdfg;skfg;lsfjg;sfgsfjglksfjd;kf;lksjd ; dfgks dfg;lksj dfg;jsf ;lksdf g;slkfg ;slkgj s;lfk;sdlgj s;lkfjg ;slkgj;lskgj;lksdfg;skfg;lsfjg;sfgsfjglksfjd;kf;lksjd ; dfgks dfg;lksj dfg;jsf ;lksdf g;slkfg ;slkgj s;lfk ;sdlgj s;lkfjg ;slkgj;lskgj;lksdfg;skfg;lsfjg;sfgsfjglksfjd;kf;lksjd ; dfgks dfg;lksj dfg;jsf ;lksdf g;slkfg ;slkgj s;lfk;sdlgj s;lkfjg ;slkgj;lskgj;lksdfg;skfg;lsfjg;sfgsfjglksfjd;kf;lksjd ; dfgks dfg;lksj dfg;jsf ;lksdf g;slkfg ;slkgj s;lfk;sdlgj s;lkfjg ;slkgj;lskgj;lksdfg;skfg;lsfjg;sfgsfjglksfjd;kf;lksjd ; dfgks dfg;lksj dfg;jsf ;lksdf g;slkfg ;slkgj s;lfk;sdlgj s;lkfjg ;slkgj;lskgj;lksdfg;skfg;lsfjg;sfgsfjglksfjd;kf;lksjd ; dfgks dfg;lksj dfg;jsf ;lksdf g;slkfg ;slkgj s;lfk

Then type, you’ll see it bounce up and down. This become VERY annoying for the user.

Switch DataSources Dynamically

I have a RadComboBox1 that I want to show nothing in until the RadComboBox2 above it has a selected value. I do this by not setting a data source on RadComboBox1. Once a value is selected in RadComboBox2 on the server side I am setting a new datasource and loading the RadComboBox1. This works the first time I have selected an option in RadComboBox2 that has associated data. When I select an item in RadComboox2 that does not have associated data, RadComboBox1 will not clear.

I have tried the following to clear RadComboBox1:

RadComboBox1.ClearSelection();

RadComboBox1.Text = string.Empty;

RadComboBox1.Items.Clear();

RadComboBox1.DataSource = null;

RadComboBox1.DataBind();

while (RadComboBox1.Items.Count > 0)

{

RadComboBox1.Items.Remove(0);

}

However nothing seems to allow me to remove the items from RadComboBox1. I have tried this code on RadComboBox2 selected index changed, on RadComboBox1 items requested and elsewhere. Any help would be appreciated.

RadTooltipManager in a Sharepoint 2007 web part

Hello,

I am working on a scheduler web part and have recently added the custom tooltip capability using the RadTooltipManager. I have followed this demo pretty my to the t: http://demos.telerik.com/aspnet-ajax/scheduler/examples/radtooltip/defaultcs.aspx It's working great in Sharepoint 2010, but when I add my web part to the Sharepoint 2007 environment, I get this nasty error and my page crashes:
"

The control with ID 'RadToolTipManager1RTMPanel' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.

"

I know for a fact that Sharepoint web parts have a script manager on the page, and just in case we're checking for its existance in the OnInit event:

protected override void OnInit(EventArgs e)

{

base.OnInit(e);

Page.ClientScript.RegisterStartupScript(typeof(Adapter20), this.ID, "_spOriginalFormAction = document.forms[0].action;_spSuppressFormOnSubmitWrapper=true;", true);

if (this.Page.Form != null)

{

string formOnSubmitAtt = this.Page.Form.Attributes["onsubmit"];

if (!string.IsNullOrEmpty(formOnSubmitAtt) && formOnSubmitAtt == "return _spFormOnSubmitWrapper();")

this.Page.Form.Attributes["onsubmit"] = "_spFormOnSubmitWrapper();";

}

// Register the ScriptManager

ScriptManager scriptManager = ScriptManager.GetCurrent(Page);

if (scriptManager == null)

{

scriptManager = new ScriptManager();

scriptManager.ID = "CWScriptManager";

scriptManager.EnablePartialRendering = true;

Controls.AddAt(0, scriptManager);

}

//scriptManager.EnablePartialRendering = true;

scriptManager.LoadScriptsBeforeUI = false;

}

Due to procedure limitations we're currently forced to use the 2010.1.309.35 version of telerik controls.

Any ideas what could be going wrong?

Perform TabClick event

Hello,

My question is pretty same as the following one:

http://www.telerik.com/community/forums/aspnet-ajax/tabstrip/rad-tab-click-event-not-firing-the-first-time.aspx

I followed the demo "TabStrip / Load on Demand RadPageView" and i can say that most of the code is missing so i had to combine the code from the other demoS in order to achieve what i want (please refer the code below).

However the thing is that i can't make it loads the very first pageview when tabs are created. After you click another tabpage it works as expected.

It is something similar to windows button control which has a "PerformClick" event.

Thanks

ASP.NET (HTML)

<telerik:RadMultiPage ID="RadMultiPage1" runat="server" SelectedIndex="0" CssClass="multiPage" />

<telerik:RadTabStrip OnClientTabSelecting="onTabSelecting" ID="RadTabStrip1" SelectedIndex="0" CssClass="tabStrip" runat="server" MultiPageID="RadMultiPage1" Skin="Office2007" Orientation="HorizontalBottom" />

CODE BEHIND (VB.NET)

Imports Telerik.Web.UI

Updating RadPane content

Greetings,

I have an application with a RadSplitter and two RadPane, one with a RadTreeView and other with diferent forms which are loaded depending on which level of the RadTreeView is selected. In those forms, the user could create or delete nodes from the tree.

The question is how can I manage those forms to reload the RadTreeView each time an update or insert is perfomed.

Kind Regards,

Francisco Cruzado
