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;  
        
                    }  
        
                }

RadGallery: Highlight of Buttons

There is a small issue with the highlightning of all the buttons on the radgallery.

When you move the mousepointer on one of the buttons and the mousepointer is on the right half of the button than it is all ok. The button is highlighted and you can press the left mouse button and the correspnding action happens.

But when you move the mousepointer from the right half of the button to the left half then there is no highlightning of the button and you can press the left mouse button and no action happens.

Regards,

RadForm and Shaped Form Performance Issues...

Hi there,

Thankyou again for this wonderful product, my test project is in completion but there are some visual and performance isssues which greatly customers satisfaction. Can you please address these issues or if they are addressed direct me to a solution.

System Specs...

1. Processor Intel Pentium Dual Core E5200 2.5Ghz

2. Motherboard - Asus Intel P5SD2-VM

3. Graphics - Onboard

4. Ram - Kingsten 1Gb

Telerik Version Currently in Use

1. Telerik Winform 2009 Q1

Scenario...

I have a standard Windows form with TitleBar Removed so that it could be made full screen.I have Added some RadButttons and Radcarousel on the form. Radcarousel Button Elements open new forms above the main background Form, which contains a background image of a standard 1024 * 768 resolution. Note - All Elements on all forms are inserted inTable Layout Panels to make things resolution independent.

Issues...

1. Flickering Issue on title bar and other form elements.

2. Increased Loading Times of components.

3. Generation of a form trail like a mouse trail of forms opend on top of the main form containing a background image. Whereas Standard forms donot suffer these problems. the issue decreases a bit if i decrease the opacity of the form, but then there ae visbility issues.

Thankyou!!!

Awaiting Response Soon...
