Render RadDropdownlist from C# code behind

Hello

Current Scenario: Currently we are generating html select (dropdown) from code behind using string builder and adding the generated HTML into literal control - which will display the HTML. Below is the code snippet.

html.Append("<select name=test id=test class='xyz' onchange=\"changeDD(this);\" >");
html.Append("<option value='1'>xyz</option>");

We have number of controls being rendered dynamically based on customer settings. Now, We are trying to replace this html select (dropdown) with Telerik RadDropdownlist.

Please suggest the approach or provide your inputs to achieve this kind of HTML rendering from code behind. Also we have JS written for some of the controls.

Please let me know if you need more details.

ImageEditor - ViewPaths

Hello,

I have this mark up in my code.

<tlrk:RadEditor ID="D0_RadArticle" runat ="server" Width="680px" Height="376px"

ToolsFile="~/XML/Editor/HelpEditor.xml" ImageManager-ViewPaths="~/Images/Help"

AnchorPathToStrip="ihs201" StripAbsoluteAnchorPaths="true" />

The client is able to select an image and store it to the database. The link that is stored is <img alt="" src="/ihs201/Images/Help/Editor/underline.jpg" />. This is fine when I am in my development server. But when I deploy my web pages to a different server I do not want the "/ihs201" in my link. If the virtual directory name is different then "ihs201" then the images link breaks. I would rather my link was <img alt="" src="../Images/Help/Editor/underline.jpg" /> . This link would enable me to access the image in other server with different name. How do I achieve something like that.

Thank you,
Kalyani

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
