Dock performance

Hi,

Can anyone say anything about how the performance is on the new Dock component compared to the old DockingManager?

We are using the old DockingManager in a rather complex form and it takes up to 10 secs. for the form to load so we are hoping for a great performance boost in the new component.

Thanks,
Brian

Sorting on a DateTime Column

Hello,

I'm having trouble with sorting on my gridview column. I've specified the DataType as datetime:

grdPackages.Columns[(int)ServerPackage.Column.Timestamp].DataType = typeof(DateTime);

However, when clicked on, it still does a Text-based sort. Is there anything else I need to do? If I were to change the column to a DateTime column, would this help? How would I go about doing this? It's a databound gridview populated from a list of custom data types.

Also, I'm also getting 'NullReferenceException' errors in my gridview formatting function on the line above, when it's called for a second time. So, the first time the grid is populated, the formatting function is called, and the column is set to typeof(DateTime). After this point, the user clicks elsewhere, causing the gridview's datasource to be set to null. Then, if they return to the same spot, the data is loaded and the formatting function is called again. This time, it throws the nullreferenceexception on that line. I don't understand why this would happen. I've verified that it happens even when the data source is the same...

Thanks!

Jeremy

Missing option to add/Remove Panel in smart tag

I recently installed the RadControls for WinForms Q2 2009 in VS2008 and I appear to be missing several options in the RadSplitContainer Tasks smart panel. Add or Remove Panel are missing as well as the Horizontal option. I dropped the RadSplitContainer control into a Docking.DocumentWindow. Any suggestions?

q2 2009 radgrid: index [pagesize] is either negative or above rows count.

After sorting with the radgrid then changing pages (or the reverse), I get: "index [pagesize] is either negative or above rows count."

The code is quite simple

    
                protected void RadGrid1_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)  
        
                {  
        
                    DataTable dt = dm.GetDtFromSQL(string.Format(SQLTemplate, ViewState["showID"]), "", ViewState["showID"].ToString(), false);  
        
                    if (dt.Rows.Count > 0)  
        
                    {  
        
                        DataView dv = dt.DefaultView;  
        
                        dv.RowFilter = ViewState["filter"].ToString();  
        
                        dv.Sort = string.Format("{0} {1}", ViewState["sort"], ViewState["order"]);  
        
                        RadGrid1.DataSource = dv;  
        
                    }  
        
                    else  
        
                    {  
        
                        RadGrid1.DataSource = null;  
        
                    }  
        
                }
