Programatic Grid creation with RadToolTip on column

We are creating a Grid dynamically based upon an ad-hoc definition of selected columns and data sources by the end-user. We have a number of columns which we need to offer the user "ToolTip" information which is database driven and specific to the value in the row.

I've been looking at building a new class which implements ITemplate and adds the field value (using a label) and attaches a RadToolTip to the label in the cell, but it seems like I have to implement the formatting/aggregates/etc on my own.

Another thought I had would be to use an BoundColumn, but override the DataBinding event (or to add an additional event to the firing of DataBind) and attach the tooltip there, but it seems like I can't. We have source code access and I can see how it's done behind the scenes, but I'm just not sure where to do it and still use the released controls.

Right now our columns inherit from the base GridColumns (GridBoundColumn, GridHyperlinkColumn) and get their values on the fly from from our settings system. Here's an example:

    
                    public class BoundGridColumn : Telerik.Web.UI.GridBoundColumn  
        
                {  
        
                    public BoundGridColumn()  
        
                    {  
        
                    }  
        
                    public BoundGridColumn(string column)  
        
                    {  
        
                            this.DataField = column;  
        
                            this.UniqueName = column;  
        
                            this.SortExpression = column;  
        
                            this.HeaderText = Utility.GetSetting(column + ".Header");  
        
                            if (Utility.GetSetting(column + ".Width").Length > 0)  
        
                            {  
        
                                int _width = Convert.ToInt32(Utility.GetSetting(column + ".Width"));  
        
                                this.HeaderStyle.Width = Unit.Pixel(_width);  
        
                                this.FooterStyle.Width = Unit.Pixel(_width);  
        
                                this.ItemStyle.Width = Unit.Pixel(_width);  
        
                            }  
        
                            else  
        
                            {  
        
                                this.HeaderStyle.Width = Unit.Pixel(100);  
        
                                this.FooterStyle.Width = Unit.Pixel(100);  
        
                                this.ItemStyle.Width = Unit.Pixel(100);  
        
                            }  
        
                            if (Utility.GetSetting(column + ".Item.Align").Length > 0)  
        
                                this.ItemStyle.HorizontalAlign = (HorizontalAlign)Enum.Parse(typeof(HorizontalAlign) , (Utility.GetSetting(column + ".Item.Align")));  
        
                            if (Utility.GetSetting(column + ".Footer.Align").Length > 0)  
        
                                this.FooterStyle.HorizontalAlign = (HorizontalAlign)Enum.Parse(typeof(HorizontalAlign) , (Utility.GetSetting(column + ".Footer.Align")));  
        
                            if (Utility.GetSetting(column + ".Header.Align").Length > 0)  
        
                                this.HeaderStyle.HorizontalAlign = (HorizontalAlign)Enum.Parse(typeof(HorizontalAlign) , (Utility.GetSetting(column + ".Header.Align")));  
        
                            // = Unit.Pixel(_width);  
        
                            if (Utility.GetSetting(column + ".Visible").Length > 0)  
        
                                this.Visible = Convert.ToBoolean(Utility.GetSetting(column + ".Visible"));  
        
                            this.DataFormatString = Utility.GetSetting(column + ".Format");  
        
                            this.DataType = System.Type.GetType(Utility.GetSetting(column + ".DataType"));  
        
                            if (Utility.GetSetting(column + ".Aggregate").Length > 0)  
        
                                this.Aggregate = (GridAggregateFunction)Enum.Parse(typeof(GridAggregateFunction) , Utility.GetSetting(column + ".Aggregate"));  
        
                            if (Utility.GetSetting(column + ".AllowFiltering").Length > 0)  
        
                                this.AllowFiltering = Convert.ToBoolean(Utility.GetSetting(column + ".AllowFiltering"));  
        
                            this.Groupable = true;  
        
                            this.ItemStyle.Wrap = false;  
        
                        }

So where/how can I attach a value specific tooltip to this column

[Solved] Add capability of RadGrid

Hi,
I have a rad grid with only Add and Delete functionality. Please note that there is no "EDIT" button on the records.
when I click on "Add" the new row for adding a new record shows up but when the grid is in Add mode, I dont see "insert" and "cancel" buttons on the new row. This thing does not happen when I have "Edit" button on the grid. Please advice as to how can I have "insert" and "cancel" buttons on the new row when there is no edit button on the grid.

Thanks

When I select the value "2" (which is "oui") on my RadioButtonList, I want the table be visible, when I select the value "1" (which is "non") then I want my table.visible=false. I do it in code behind but I would like to do it with ajax. Is it possible?
Thanks you!

this._folderCache JS error

I keep getting the following error:

this._folderCache is undefined

It appears to be coming from the _changeCurrentFolder function: this line in the RadFileExplorer javascript:

    
            if(this._folderCache[e]!=null&&!f){this._onCallbackResponse(this._folderCache[e],j);}

Now, this perplexes me because it appears that the FileExplorer works correctly in all other regards except when I initiate some action that refreshes the left hand tree view pane. (Which by the way, loads correctly as I interact with opening folders...)

Deleting a file, folder, or even clicking the refresh icon causes the above error.

So my question is - How could this variable not be defined (it appears to be defined in the initialization of the object, javascript side)? Is there some way for me to debug this on my end that isn't apparent to me? I am using a custom content provider for this and so far I am happy with everything else other than this!

Thanks

Change "Generate New image" text

Hi everyone,

I've just installed the new release (Q3 2009) of the RadControls for ASP.NET Ajax, since the new version corrected the bug concerning changing the captcha textbox label programmatically, which work fine now.

But I just notice that it seems to have the same problem with the CaptchLinkButtonText property. I tried to change it programmatically in the page_Load event, but the change is not applied when the control is rendered. I need to be able to change it programmatically if I want to use this functionnality, since my web site is multi-language (english and french)

Is it a known problem or am I doing something wrong?

Thanks,

Captcha

No RecurrenceRule data on OnAppointmentInsert

Hi,

I have a function:

    
            protected void scheduler_AppointmentInsert(Object sender, SchedulerCancelEventArgs e) 
        
            { 
        
            ... 
        
            }

When using all of RadScheduler's default templates for inserting and such, RecurrenceRule always seems to be empty and RecurrenceState is always NotRecurring. I'm using e.Appointment.RecurrenceRule to try to access it. All of the other data is there (title, end time, start time)

As far as I know, we are currently using the most up-to-date patch (that isn't officially released yet). Is this a bug or am I doing something wrong?
