ComboBox dynamic adding checkboxes to template

Hello,

I've been searching the forums and found some similar topics but I still can't get it to work so I thought I'd post my own to see what I'm doing wrong.

My situation is simple, I have a ComboBox and I want the dropdown to have checkboxes, as I understand there is no easy way to just add a checkbox to a ComboBox, instead I have to use the ItemTemplate.

At the moment I have a class that uses the ITemplate, it has a InstantiateIn method and there it gets the "dynamic" data from a DB.

It looks something like this, don't mind the extra code it's still very early and just trying to get things to work:

public void InstantiateIn(Control container)

{

object[] searchoptions = GetProxy().GetSearchOptionList();

DataSet so = (DataSet)searchoptions[0];

List<SearchOption> searchOpt = new List<SearchOption>();

for (int k = 0; k < so.Tables.Count; k++)

for (int j = 0; j < so.Tables[k].Rows.Count; j++)

{

SearchOption search = new SearchOption();

search.ID = so.Tables[k].Rows[j].ItemArray[0].ToString();

search.name = so.Tables[k].Rows[j].ItemArray[1].ToString();

searchOpt.Add(search);

CheckBox box = new CheckBox();

box.Text = search.name;

box.ID = search.ID;

box.DataBinding += new EventHandler(box_DataBinding);

container.Controls.Add(box);

}

It simply loops over it and takes out all the data, and attaches a Eventhandler

private void box_DataBinding(object sender, EventArgs e)

{

CheckBox target = (CheckBox)sender;

RadComboBoxItem item = (RadComboBoxItem)target.BindingContainer;

string itemText = (string)DataBinder.Eval(item, "Text");

target.Text = itemText;

}

But this doesn't work, the biggest problem is that I don't really get it myself why I have to go on with Templates and all this, I just want a dropdown with checkboxes, so maybe I'm overcomplicating things here or maybe I just don't understand.

Any help is welcome.

[Solved] Trouble displaying data with TreeView

Hoping someone can direct me down the correct path. Trying to have a Treeview control on a page where users can use the checkbox feature on the fields they would like queried out of the database.

This is what I have: Category (6 categories)
Group Desc (to many to list)
Friendly Column Name (to many to list)

See attached image of the data that I return from SQL.

I would like
    Category
        Group Desc
            Friendly Name (datatextfield = QualifiedName)

When attempting to get it working I get several different errors. Currently the error is

These columns don't currently have unique values.

<telerik:radtreeview id="RadTreeView1" runat="server" checkboxes="True" datafieldid="Category"

datafieldparentid="GroupDescr" datasourceid="SqlDataSource1" datatextfield="FriendlyName" DataValueField="QualifiedName"></telerik:radtreeview>

Question on RadStyleSheetManager

Hello, for our web app we have a customized skin that was based off a Telerik built-in skin. The master page automatically creates stylesheet references for each Telerik object. We are running into the known problem of IE only being able to load the first 30 CSS files.

Based on what I've seen in the Telerik Help, the suggestion would be to add a RadStyleSheetManager, take the skin CSS files and images and set them to embedded resources in a separate project (as outlined here http://www.telerik.com/help/aspnet-ajax/radstylesheetmanager.html).

My questions is as follows: if we go this route, and we want to change something in one of the skin's CSS files, does that mean we have to re-build and re-deploy? In other words would we lose the ability to make a seamless change to a skin's CSS file?

Preformatted text in RadEditor in FireFox

We're having issues with preformatted text in the RadEditor when using FireFox 2.0. We're using the RadEditor for a documentation site where we need to display source code (C#, xml markup, etc). We're trying to use the <pre> tags to format this code. When we wrap content in <pre> tags and switch between design and code views in FireFox, tags are added where line breaks used to be. In other words:

<pre>asdfasfd
asdfasfd
asfdasfd</pre>

gets changed to this:

<pre>asdfasfd 
asdfasfd 
asfdasfd</pre>

The same thing happens if we designate another tag, like <code> and give it a white-space:pre; style in the CSS stylesheet. The editor seems to recognize the preformatted style that's been applied and inserts the tags.

We do not seem to experience this behavior in IE7.

Thanks for your help.

[Solved] RadGrid Default Column Widths under IIS

It appears that the initial column widths for the grid are not being defaulted consistently when deployed to the ASP.NET Development Server versus IIS. Both IE and FF work correctly when run from the ASP.NET Dev Server, but once I publish the site and run it under IIS, the grid columns are not set to the default width in IE, but in FF they are still fine.

See the attached screen shots for the 4 combinations of IE vs. FF and ASP.NET vs. IIS. It's the "Invoice Details" grid that is the problem in the IE/IIS combination.

This is how I'm setting up the grid in the markup:

    
            <asp:Content ID="Content2" ContentPlaceHolderID="content" runat="Server">  
        
                <div style="vertical-align: top;height: 100%;">  
        
            …snip…  
        
                    <telerik:RadSplitter ID="ContentSplitter" Runat="server" Height="100%" Width="100%" 
        
                        Orientation="Horizontal">  
        
            …snip…  
        
                        <telerik:RadPane ID="BodyPane" runat="server" Height="100%" Width="100%" Scrolling="Y" 
        
                            OnClientResized="ClientResized">  
        
                            <telerik:RadSplitter ID="AppSplitter" Runat="server" Height="100%">  
        
            …snip…  
        
                                <telerik:RadPane ID="AppPane" runat="server" MinWidth="40" Scrolling="Y" Width="100%">  
        
            …snip…  
        
                                    <telerik:RadAjaxPanel ID="HeaderRadAjaxPanel" runat="server">  
        
            …snip…  
        
                                    <telerik:RadGrid ID="grdDetails" runat="server"   
        
                                        AllowFilteringByColumn="True" AllowPaging="True" AllowSorting="True"   
        
                                        AutoGenerateColumns="False" GridLines="Both" ShowFooter="true" 
        
                                        Height="400" Width="100%" 
        
                                        AllowAutomaticInserts="true" AllowAutomaticUpdates="true" 
        
                                        AllowAutomaticDeletes="true" 
        
                                        OnItemCreated="grdDetails_ItemCreated" 
        
                                        OnNeedDataSource="grdDetails_NeedDataSource" 
        
                                        OnItemDataBound="grdDetails_ItemDataBound">  
        
                                        <MasterTableView TableLayout="Fixed" EditMode="InPlace" CommandItemDisplay="Top" /> 
        
                                        <PagerStyle AlwaysVisible="true" Mode="NextPrev" /> 
        
                                        <ClientSettings> 
        
                                            <Scrolling AllowScroll="true"   
        
                                                EnableVirtualScrollPaging="true" SaveScrollPosition="true"   
        
                                                UseStaticHeaders="true" /> 
        
                                            <Resizing AllowColumnResize="true"   
        
                                                ClipCellContentOnResize="true" EnableRealTimeResize="true"   
        
                                                ResizeGridOnColumnResize="true" /> 
        
                                            <ClientEvents OnRowClick="grdDetails_RowClick" /> 
        
                                        </ClientSettings> 
        
                                    </telerik:RadGrid> 
        
                                    </telerik:RadAjaxPanel> 
        
                                </telerik:RadPane>   
        
                            </telerik:RadSplitter> 
        
                        </telerik:RadPane> 
        
                    </telerik:RadSplitter> 
        
            …snip…  
        
                </div> 
        
            </asp:Content>

The columns are then created server-side in the code-behind, during the grid's PreRender event. Every column has an explicit width set.

Does anyone have any ideas/suggestions on what the issue might be? Everything I’ve tried has not forced the grid to behave.

My environment:
- Windows 7
- IIS 6.1
- VS 2008 SP1 (.NET 3.5 SP1), C#
- Telerik Q1 2010 Trial Version (2010.1.415.35)
- IE 8.0.7600.16385
- Firefox 3.6

Thanks in advance for any help.

TypeError :Object doesnt support this property or method

Hi I use the telerik RadComboBox and on a client side event i use the 'RadComboBoxEventArgs' variable to get the selected item .

The code would be

ComboBoxEventArgs.get_item() 

The RadComboBox is an edittable combo box that is a user can search for a particular record by typing in to it.

Now, if the user searches for an item which is present in the list everything just works fine.

But if the user types in something that is not in the list then the code

ComboBoxEventArgs.get_item()

throws an error "TypeError :Object doesnt support this property or method"

I am using the telerik control with the version "2010.3.1401.40"

Regards,
Francis
