I've tried to implement my custom filter, as described in the following article:

http://www.telerik.com/help/aspnet-ajax/contentfilters.html

As a result, I got the following error:

"Telerik.Web.UI.Editor.Filter is null or not an object."

Could someone help please?

P.S. I've already added RadScriptManager and RadAjaxManager on my page.

radEditor setFocus problem

Hi,

I am trying to set focus back on the radEditor after saving the contents. Also setting the cursor to the end of the text.

I have the following scripts set up from looking at these forums. The error I get 'Object doesn't support this property or method' on the setFocus() call.

            Telerik.Web.UI.Editor.CommandList["Save"] = function(commandName, editor, args) {
                var btnSave = $get("<%=btnDocumentSave.ClientID%>");
                btnSave.click();
                focusRadEditor();
            };

            function focusRadEditor() {
                var docEditor = document.getElementById('<%=Page.Master.FindControl("cphMain").FindControl("DocumentEditor1").FindControl("tbDocumentSource").ClientID%>');
                docEditor.setFocus();
                var contents = docEditor.get_document();
                contents.execCommand("SelectAll", null, false);
                //Collapse selection to the end
                docEditor.getSelection().collapse();
            }

Anyone know what I'm doing wrong? I'm using Q3 2008 build, and IE6.

breaking change in 2010 Q3 - positions and indices

Hi,

We save the location of raddocks on our page with the following code:

void MainRadDockLayout_LoadDockLayout(object sender, DockLayoutEventArgs e)
{
...
e.Positions = serializer.Deserialize<Dictionary<string, string>>(positionsAndIndices[0].ToString());
e.Indices = serializer.Deserialize<Dictionary<string, int>>(positionsAndIndices[1].ToString());
...
}

Where positionsAndIndicies is a json string. This used to work until we upgraded to Q3 2010 and now we get an error:

Property or indexer 'Telerik.Web.UI.DockLayoutEventArgs.Positions' cannot be assigned to -- it is read only
Property or indexer 'Telerik.Web.UI.DockLayoutEventArgs.Indices' cannot be assigned to -- it is read only

Is there a better way to do this in the new release or should we just populate the positions and indices in a loop with e.Indices.Add(...)?

Thanks

ImageClickEventHandler not firing

Hi

I am trying to add an ImageClickEventHandler onto an imagebutton.
Althought i cant get it to fire. I am doing this within the ItemDataBound event of the grid . I tried changing EnableViewState to false, but that made no difference.

Any ideas would be greatly appreciated

    
                protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)    
        
                {  
        
                    ImageButton imgBtnHolder = new ImageButton();  
        
                   if (e.Item is GridDataItem)    
        
                    {  
        
                        switch (e.Item.OwnerTableView.Name)  
        
                        {  
        
                            case "Vis":  
        
                                {  
        
                                    GridDataItem item = (GridDataItem)e.Item;  
        
                                    imgBtnHolder = ((ImageButton)item["colDelete"].FindControl("imgDelete"));  
        
                                    imgBtnHolder.ImageUrl = "data_delete.gif";  
        
                                    imgBtnHolder.AlternateText = "Delete";  
        
                                    imgBtnHolder.OnClientClick = "return confirm('Are you sure you want to remove this');";  
        
                                    imgBtnHolder.CommandName = "Delete";  
        
                                    imgBtnHolder.CommandArgument = "cccc";  
        
                                    imgBtnHolder.Click +=new ImageClickEventHandler(imgBtnHolder_Click);  
        
                                    break;  
        
                                }  
        
                        }  
        
                    }    
        
                }  
        
                void imgBtnHolder_Click(object sender, ImageClickEventArgs e)  
        
                {  
        
                    throw new NotImplementedException();  
        
                }

Thanks

Custom Provider and Advanced Form

Hi,
I have a custom provider that Ive created and its works fine with the default edit form. The issue that Im running into is that once I modify my RadScheduler to use an advanced edit form, none of the drop down controls (all of which are populated via resources in the custom provider) have the selected value in edit mode.
Ive tried adding binding expressions for each of the controls in the advanced edit and insert templates, but when I do that I get an error saying that that the Appointment object does not have a definition for a property.
To get around that I can add the CustomAttributes to the radScheduler definition but then the control does not save the data. Also, Im not working with attributes, they are resources.

Can telerik please provide some guidance on this? and please don't recommend that I read the Advanced Templates Demo. Ive read it a number of times and it has not helped.

Custom Provider no checkboxes

I built a custom provider that has mutlivalues for field called attendees. When I just run that as is (without changing the advanced template) the list of attendees shows up but there are no check-boxes to select from. Do you know why?

Thanks.

Bar Chart - Active Region click event

Hi All,
In our application we have a dynamically generated Bar Chart and to this bar chart we are creating ChartSeries and adding ChartSeries item and while adding the items to the series i am trying to register a click event for the ActiveRegion and the code is as below in bold but the event never gets fired.

ChartSeries

s0 = new ChartSeries();

s0.Name =

string.Empty;

for (int ic = 0; ic < dt.Rows.Count; ic++)

{

ChartSeriesItem seriesItem = new ChartSeriesItem();

seriesItem.YValue = (

double)dt.Rows[ic]["Quantity"];

seriesItem.Name =

"Settlement";

seriesItem.Appearance.Border.Color =

Color.Black;

DateTime dt1 = Convert.ToDateTime(dt.Rows[ic]["Date"]);

seriesItem.XValue = dt1.ToOADate();

seriesItem.ActiveRegion.Click +=

new RegionClickEventHandler(ActiveRegion_Click);

seriesItem.ActiveRegion.Tooltip =

"Number of News:" + dt.Rows[ic]["Quantity"] + "";

RadToolTipManager1.TargetControls.Add(

null, seriesItem.ActiveRegion.Tooltip.ToString(), true);

s0.AddItem(seriesItem);

}

radchart1.Series.Add(s0);
I even tried the below way of registering the click event for the Active region at chart level but in vain.

radchart1.ChartTitle.ActiveRegion.Click +=

new RegionClickEventHandler(ActiveRegion_Click);

Please correct me if i am doing something wrong.

Regards,
Preetam.

In my client-side onLoad function I check the combobox's value, and, if its value is PieChart, I attempt to hide some controls on the page from the user. Setting the checkbox's visibility property to Collapse, Hidden, etc.. doesn't do anything. The same with setting its height and width to 0 -- it is still visible. If I disable it, it becomes disabled. I am able to affect the controls on its left and right -- the RadDateTimePicker and the label both disappear in IE8 perfectly fine.

Any suggestions on how to remove this finicky box would be appreciated.
