[Solved] Creating templated RAD Combo Box at runtime

I need to dynamically create RAD Combo Boxes and databind them at runtime. I have a template which consists of a checkbox and a label that holds the "text" of the combo box. Here is the template definition:

                        class GroupTopicTemplate : ITemplate         
                {         
                    public void InstantiateIn(Control container)         
                    {         
                        HtmlGenericControl div = new HtmlGenericControl("div");         
                        CheckBox chkSelected = new CheckBox();         
                        chkSelected.ID = "chkSelected";         
                        int rowNumber = int.Parse(container.Parent.ClientID.Substring(container.Parent.ClientID.Length - 1)) + 1;         
                        chkSelected.Attributes.Add("onclick", "onCheckBoxClick(" + rowNumber.ToString() + ")");         
                        div.Controls.Add(chkSelected);         
                        Label lblName = new Label();         
                        lblName.Text = "Text";         
                        lblName.DataBinding += new EventHandler(lblName_DataBinding);         
                        lblName.ID = "lblName";         
                        container.Controls.Add(div);         
                    }         
                     
                    void lblName_DataBinding(object sender, EventArgs e)         
                    {         
                        Label target = (Label)sender;         
                        RadComboBoxItem item = (RadComboBoxItem)target.BindingContainer;         
                        string itemText = (string)DataBinder.Eval(item, "Text");         
                        target.Text = itemText;         
                    }         
                }         

The combo box is created in Page_Init as follows:

                            RadComboBox rcGroupTopics = new RadComboBox();         
                    rcGroupTopics.ID = "rcGroupTopics" + rowString;         
                    rcGroupTopics.EmptyMessage = "None";         
                    rcGroupTopics.HighlightTemplatedItems = true;         
                    rcGroupTopics.AllowCustomText = true;         
                    rcGroupTopics.Skin = "WebBlue";         
                    rcGroupTopics.ItemTemplate = new GroupTopicTemplate();         
                    td.Controls.Add(rcGroupTopics);         

The combo box is populated as follows:

                    DataView dv = new DataView(dt);         
                     
            dv.Sort = "name";         
                     
            TopicDropDownList.DataSource = dv;         
            TopicDropDownList.DataTextField = "name";         
            TopicDropDownList.DataValueField = "tagname";         
            TopicDropDownList.DataBind()         

I tried to put the above code in Page_Init (below the above code) and in Page_Load. The problem is, InstantiateIn() is not called until DataBind(), so the data binding event handler is attached too late and the label has no text. Is there a way around this?

Thanks in advance,

Boris Zakharin

IE 8 Text Centre Issue

Hi,

I am having an issue with how the text centre tool behaves in IE. To reproduce:

1) Paste the following text into an editor

This text should not centre
This text should centre

2) Highlight "This text should centre"

3) Click the text centre tool

In Chrome it behaves as expected and centre's "This text should centre" but not "This text should not centre". However, in IE bot lines are centered.

Any suggestions?

RadGrid Export to PDF or Excel feature does not work with RadAjaxManager

We are using RadGrid to display data on ASPX page where AJAX is implemented using RadAjaxManager and asp:ScriptManager. We have a button on click of which we need to export grid data to PDF or Excel format. OnClick event of this button we have written following statement:

RadGrid1.MasterTableView.ExportToPdf();

But it does not work (File Open-Save dialogue box is not displayed.)

When we debugged, we can see that control goes to above statement.

When button is placed outside ScriptManager, it works(it shows file open-save box).

Do we need to make any changes in the behaviour of RadAjaxManager to achieve this? Kindly help.

Scheduler not updating after RadAjaxManager AjaxRequest

Hi,

I am using radwindow to provide a custom appointment setup (it is sufficiently complex, using tab strip, several radEditors, etc) that trying to do it inline would have been a problem. It works fine and updates a dataset. On radwindow close, I am calling AjaxRequest, and then trying without success to update the appointments.

I am getting a datasource on ajaxrequest and have tried rebind, etc. without success. Even though the data has changed, the subject, times, etc of the appointments do not update. Only if I do something such as a drag drop which fires AppointmentUpdate and then the data gets refreshed in the modified appointment. Does anyone have a suggestion on how to force the just modified appointment to update when using an Ajax callback? Thanks.

Anyone has an idea ?

Adding a link button to a root panel item

I'm trying to use a panel bar to create a similar menu to this:

http://www.asos.com/Men/Jeans/Cat/pgecategory.aspx?cid=4208#parentID=Rf-100&pge=0&pgeSize=20&sort=-1&state=Rf-100%3DJeans

I've managed to create the basic functionality, but cannot add a 'clear' button to the root panel item whenever a selection is made. How would I go about doing this? I have included an example panel item below. In this example I would need to be able to add it in the cblStyle_IndexChanged code:

<telerik:RadPanelItem Text="Style" Expanded="true">

<Items>

<telerik:RadPanelItem>

<asp:CheckBoxList ID="cblStyle" runat="server" AutoPostBack="true" OnSelectedIndexChanged="cblStyle_IndexChanged">

</asp:CheckBoxList>

</ItemTemplate>

</telerik:RadPanelItem>

</Items>

</telerik:RadPanelItem>

Regards,

Richard
