Databound PanelBar with ContentTemplates?

Hello,

I am trying to databind a RadPanelBar (2010 Q2 release) to achieve a specific behavior, and I am having trouble getting it to work.

If I have the panelbar in my aspx like so:

<telerik:RadPanelBar ID="rpbRel" runat="server" OnItemDataBound="rpbRel_ItemDataBound" >

<ItemTemplate>

<div class="DestinationWrapperBox">

<asp:TextBox runat="server" id="txtRel" />

</div>

</ItemTemplate>

</telerik:RadPanelBar>

And code-behind like so:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

Dim colTypes As System.Collections.ObjectModel.Collection(Of RelationshipType)

rpbRel.DataSource = colTypes

rpbRel.DataTextField = "Name"

rpbRel.DataValueField = "ID"

rpbRel.DataBind()

End Sub

Protected Sub rpbRelationships_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadPanelBarEventArgs)

Dim oRelType As RelationshipType

Dim txtTemp As TextBox

oRelType = CType(e.Item.DataItem, RelationshipType)

txtTemp = CType(e.Item.FindControl("txtRel"), TextBox)

If Not IsNothing(txtTemp) Then

txtTemp.Text = oRelType.Name

End If

End Sub

Then what I get is a PanelBar that works correctly, but the items are not collapsible. I have read in various places that I should add RadPanelItem and add a ContentTemplate and put my template there.

If I move the aspx template code, like so:

<telerik:RadPanelBar ID="rpbRel" runat="server" OnItemDataBound="rpbRel_ItemDataBound" >

<Items>

<telerik:RadPanelItem runat="server">

<ContentTemplate>

<div class="DestinationWrapperBox">

<asp:TextBox runat="server" id="txtRel" />

</div>

</ContentTemplate>

</telerik:RadPanelItem>

</Items>

</telerik:RadPanelBar>

And leave my codebehind the same, then I get collapsed elements that won't expand.

I have traced into the databound procedure under this second scenario, and when it binds e.item is a RadPanelBarItem that has no child items or controls, so the e.item.findcontrol("txtRel") returns nothing.

I feel like I must be binding something wrong somewhere, but I am not sure how to accomplish what I want.

Ideally, I will get PanelBarItems that have their text set to "Name", and have a textbox "under" them, that can be shown or hidden by clicking on the panelbar. The first example gets me everything except the ability to collapse them.

Is it possible to do what I want?

The data area passed to a system call is too small.

I am using Telerik.Web.Design version 2010.1.630.20, and get the following error when opening the document manager of the telerik editor:

The data area passed to a system call is too small.

I have been in touch with my hosting provider, and they believe this is because the code needs 'full trust level' whereas the host only provides 'medium trust level'.

How can I fix this?

Thanks

[Solved] RadDock Custom Attributes Undefined in FireFox

I have a simple program where I assign attributes to a raddock in Page_Load and then pull these attributes using Javascript when the dock is moved (dock.get_element().MyAttribute). In IE, this works great, but in FireFox and Safari the "get_element().MyAttribute" always returns "undefined". I'm assuming it is simple syntax, but need some guidance.

ASPX:

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script type="text/javascript">

var zones;

function OnClientInitialize(dock, args) {

zones = Telerik.Web.UI.RadDockZonesGlobalArray;

}

function OnDockChangedPosition(dock, args) {

var zone;

zone = dock.get_dockZone();

var sDockJustMoved;

sDockJustMoved = "";

sDockJustMoved = dock.get_element().TestDock + "~" + zone.get_element().TestZone;

alert(sDockJustMoved);

}

</script>

<html xmlns="http://www.w3.org/1999/xhtml">

CODE:

RadDock1.Attributes.Add("TestDock", "Dock Attribute")

RadGrid Paging after bending from search

Hi,
In this case I am binding the grid programmatically in the page load, then when a user does a search, I am binding the grid with a different dataset, when I enable paging after the search it binds back the original dataset; here is the code:

public partial class PageSearch : System.Web.UI.Page

{

public ACHPagingDLL.dl dl = new ACHPagingDLL.dl();

protected void Page_Load(object sender, EventArgs e)

{

LoadGrid();

}

public void LoadGrid()

{

DataSet dsPatients = dl.c_FN_Paging_getAllEmployees();

rgEmployees.DataSource = dsPatients;

rgEmployees.DataBind();

}

protected void btnSearch_Click(object sender, EventArgs e)

{

if (txtSearch.Text.Length < 2)

{

litResult.Visible = true;

litResult.Text = "<FONT color=#cc0000 size=3>Search for 2 or more characters!</FONT>";

LoadGrid();

return;

}

else

{

DataSet dsSearch = dl.c_FN_seachEmployees(txtSearch.Text);

rgEmployees.DataSource = dsSearch;

rgEmployees.DataBind();

}

And here is the HTML:

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server">

<table class="style4">

<tr>

<td class="style5">

Search for employee by name:</td>

<td class="style6">

<telerik:RadTextBox ID="txtSearch" Runat="server" Width="160px">

</telerik:RadTextBox>

<telerik:RadButton ID="btnSearch" runat="server" onclick="btnSearch_Click"

Text="Search">

</telerik:RadButton>

</td>

<td>

<asp:Literal ID="litResult" runat="server"></asp:Literal>

</td>

</tr>

<tr>

<td colspan="3">

<telerik:RadGrid ID="rgEmployees" runat="server" AllowPaging="True"

AutoGenerateColumns="False" GridLines="None" Skin="WebBlue">

<MasterTableView pagesize="20">

<CommandItemSettings ExportToPdfText="Export to Pdf">

</CommandItemSettings>

<Columns>

<telerik:GridBoundColumn DataField="EmployeeNo" UniqueName="EmployeeNo"

Visible="False">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="EmployeeName" HeaderText="Employee"

UniqueName="EmployeeName">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Pager" HeaderText="Pager"

UniqueName="Pager">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Office" HeaderText="Office#"

UniqueName="Office">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Cell" HeaderText="Cell Phone"

UniqueName="Cell">

</telerik:GridBoundColumn>

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

UniqueName="Email">

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

<HeaderContextMenu EnableImageSprites="True"

CssClass="GridContextMenu GridContextMenu_Default">

</HeaderContextMenu>

</telerik:RadGrid>

</td>

</tr>

<tr>

<td colspan="3">

</td>

</tr>

</table>

</telerik:RadAjaxPanel>

I am not sure if there should be a code to be inserted in the index paging?
Please let me know.

Thank you in advance,
Shehab

Mega Drop-Down with XML file?

Hello,

I am currently using the regular menu control and loading an XML file for the content of the menu. Can this still be down when using a mega drop-down? How would the XML file be structured? I haven't found any information on this and I am guessing that the mega drop-down doesn't support this...

thanks,

Steve
