Microsoft jscript runtime error Parameter name: panelsCreated[0]

I am not sure which control this error should be mapped to.
I have an asp.net wizard and the wizard pages come from user controls. On some of those pages I have a radgrid.
On one of the page I have a chart and the next page after that is the one that has radgrid. I get the error Microsoft jscript runtime error Parameter name: panelsCreated[0] and the chart does not load for me. If I use asp.net grid instead of radgrid on that page then everything works fine.

Below is the ascx page that has the radgrid.

<%@ Control Language="c#" Inherits="ucBBucket" CodeFile="ucBBucket.ascx.cs" %>

<asp:ScriptManagerProxy ID="ScriptManagerProxy1" runat="server">

Aggregated footer with LoadOnDemand not working

Hi folks.

I have a treelist control on my page where I load the items dynamicaly. At each section I'd like to have aggregated sums at the bottom. I thing I have all set correctly regarding online demos but the result footer are all empty.

I use this code:

<telerik:RadTreeList ID="rtlData" AllowLoadOnDemand="true" runat="server" AutoGenerateColumns="false"
OnChildItemsDataBind="RadTreeList_ChildItemsDataBind" OnNeedDataSource="RadTreeList_NeedDataSource"
DataKeyNames="CssClass,ParentId" ParentDataKeyNames="CssClass,ParentId" OnItemCreated="RadTreeList_ItemCreated"
OnItemDataBound="RadTreeList_ItemDataBound" ShowFooter="true">
<Columns>
<telerik:TreeListBoundColumn DataField="ProductCatL3" UniqueName="ProductCatL3" HeaderText="Produkt L3">
</telerik:TreeListBoundColumn>
<telerik:TreeListBoundColumn DataField="ProductCatL2" UniqueName="ProductCatL2" HeaderText="Produkt L2">
</telerik:TreeListBoundColumn>
<telerik:TreeListBoundColumn DataField="ProductCatL1" UniqueName="ProductCatL1" HeaderText="Produkt L1">
</telerik:TreeListBoundColumn>
<telerik:TreeListBoundColumn DataField="State" UniqueName="State" HeaderText="Stav" DataType="System.Decimal" DataFormatString="{0:C2}" Aggregate="Sum">
</telerik:TreeListBoundColumn>
<telerik:TreeListBoundColumn DataField="Avg1Month" UniqueName="Avg1Month" HeaderText="Průměr 1 měsíc" DataFormatString="{0:C2}" Aggregate="Avg">
</telerik:TreeListBoundColumn>
<telerik:TreeListBoundColumn DataField="Avg3Months" UniqueName="Avg3Months" HeaderText="Průměr 3 měsíce" DataFormatString="{0:C2}" Aggregate="Avg">
</telerik:TreeListBoundColumn>
<telerik:TreeListBoundColumn DataField="ApprovedLimit" UniqueName="ApprovedLimit" HeaderText="Schválený limit" DataFormatString="{0:C2}" Aggregate="Sum">
</telerik:TreeListBoundColumn>
<telerik:TreeListBoundColumn DataField="CssClass" UniqueName="Css" HeaderText="CSS" Visible="false">
</telerik:TreeListBoundColumn>
<telerik:TreeListBoundColumn DataField="ParentId" UniqueName="ParentId" HeaderText="ParentId" Visible="false">
</telerik:TreeListBoundColumn>
</Columns>
</telerik:RadTreeList>

What am I doing wrong that no footer are calculated and it only shows empty fields?

Sincerely
Scarlaxx

RadGrid Button to Open PDF document

I'm trying to add a button to a grid that opens a "converted" pdf file in code behind. Everything seems to be working as far as creating the bytes but nothing opens.

code: pdfFile does have results because I saved it locally just to make sure. It just won't open.

Dim DocumentServiceWS As New DocumentServices

Dim pdfFile As Byte()

pdfFile = DocumentServiceWS.GetDRDocumentPDF(_PRO, _DocType)

If Not (pdfFile Is Nothing) Then

Response.Buffer = True

Response.Clear()

Response.ContentType = "application/PDF"

Response.AddHeader("Content-Disposition:", "attachment; filename=Result.pdf")

Response.BinaryWrite(pdfFile)

Response.Flush()

Response.End()

End If

[Solved] Setting Page Size when using Custom Paging

I setup a pager template per your example at:
http://demos.telerik.com/ASPNET/Prometheus/Grid/Examples/Programming/PagerTemplate/DefaultCS.aspx

This works fine by itself. I can set the page size successfully and the grid will change to the appropriate number of rows. I then implemented custom paging in order to speed up the database calls per your example at:
http://demos.telerik.com/ASPNET/Prometheus/Grid/Examples/Programming/CustomPaging/DefaultCS.aspx

For some reason the page size is not getting saved, so the when the post back occurs it still shows ten. This javascript function from the 2nd is example is getting called in both cases, but on the page load of the post back the first contains the updated page count while the other does not. Does custom paging keep this feature from working? If so is there a different way I should be setting the page count when using custom paging?

Thanks!
Levi

[Solved] Styling RadDock through CSS

Hi,

I am trying to apply CSS to a RadDock and having a bit of trouble getting things to work.

For example I am trying this CSS:

.rdExpand, .rdCollapse, .rdCollapsed {

background-position: 0px 0px !important;

height:60px !important;

}

When I inspect it in Chrome I can see it there but it is being overridden by value in WebResource.axd:

.RadDock.rdCollapsed {

height: 27px!important;

}

BTW I tried appending the classes with "div" like below but no dice :(

div.rdExpand, div.rdCollapse, div.rdCollapsed {

background-position: 0px 0px !important;

height:60px !important;

}

If there anyway of overridding this value with the one I have in my CSS?

Thanks,

Dave.

Combobox Dropdown doesn't show after item is clicked

I have a combo box inside an ajax panel like so

<telerik:RadScriptManager ID="manager" runat="server"></telerik:RadScriptManager>

<telerik:RadAjaxPanel ID="RadAjaxPanel3" runat="server" LoadingPanelID="RadAjaxLoadingPanel1">

<telerik:RadComboBox ID="userInput" runat="server" AllowCustomText="True" CausesValidation="false" ShowToggleImage="False"

ShowMoreResultsBox="true" EnableLoadOnDemand="True" MarkFirstMatch="True"

OnItemsRequested="LoadSearch"

ErrorMessage="Value not Found" AutoPostBack="True" Width="300">

<CollapseAnimation Duration="1000" Type="InBack" />

</telerik:RadComboBox>

</telerik:RadAjaxPanel>

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" SkinID="Hay"

Height="25px" Transparency="1" BackgroundPosition="Center" >

<img alt="Loading..." src="../images/loading.gif" style="border: 0px;" />

</telerik:RadAjaxLoadingPanel>

When I click in it, it loads items and if I start typing, it also searches correctly. However, once I select an item, no more items will load. Even if I delete text, nothing comes up. Here's my code behind

protected void Page_Load(object sender, EventArgs e)

{

if (!Page.IsPostBack)

{

userInput.DataSource = GetCustomers();

userInput.DataValueField = "Key";

userInput.DataTextField = "Value";

userInput.DataBind();

}//if !page.ispost

}//PageLoad

protected void LoadSearch(object sender, RadComboBoxItemsRequestedEventArgs e)

{

//get the list based on the search

IEnumerable<Vw_CustomersSearchView> customers = DbRepository.GetCustomersSearchView().Where(c => c.Customer.Contains(e.Text));

//how many items we'll show

int itemsPerReq = 10;

//keep count of the items

int count = 0;

RadComboBox box = (RadComboBox)sender;

box.Items.Clear();

//make sure we have at least one record

if (customers.Count() > 0)

{

//now add any customer items

foreach (var i in customers)

{

//if we're above 10, exit the loop

if (count >= itemsPerReq)

{

break;

}//if count > itemsper

//if we're here, add the items

box.Items.Add(new RadComboBoxItem(i.Customer, i.UserName));

count++;

}//foreach

}//if customers.count

else

{

e.Message = "No matches";

}

}//LoadSearch

/// <summary>

/// this returns a dictionary of the customers for the customer dropdown

/// </summary>

/// <returns></returns>

protected Dictionary<string, string> GetCustomers()

{

Dictionary<string, string> customersList = new Dictionary<string, string>();

//now add the items

var cTable = DbRepository.GetActiveCustomers().Where(a => a.LoyaltyCardNumber != null).Select(a => new {a.UserName, a.FirstName, a.LoyaltyCardNumber, a.LastName});

foreach (var i in cTable)

{

string name = String.Format("{0}{1}{2}{3}{4}", i.FirstName, " ", i.LastName, " - ", i.LoyaltyCardNumber);

customersList.Add(i.UserName, name);

}//foreach

return customersList;

}//GetCustomers

/// <summary>

/// if they picked an item in the combox box, repopulate it

/// </summary>

/// <param name="sender"></param>

/// <param name="e"></param>

protected void userInput_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)

{

userInput.DataSource = GetCustomers();

userInput.DataValueField = "Key";

userInput.DataTextField = "Value";

userInput.DataBind();

}//resetPasswordButtonClick

Here's a video of what's happening. How do I make it pull the dropdown again, even after you select an item. https://dl.dropboxusercontent.com/u/4979877/combo.swf
