Tired of VS2008 performance

I don't know what else to do to improve Visual Studio 2008 performance when working the asp.net pages (specially with Telerik components). I have a Core 2 Duo + 2 Gb workstation and performance is awful. For every click I do in every operation I must wait 2-3 seconds for operation to complete. I come form a Delphi background where everything was so fast, and now I must use this heavy Microsoft products.

I uploaded a screen capture. http://rapidshare.com/files/317500723/Capture.wmv.html
It shows how much time it takes to type some text inside Teleriks components. Please tell me if this normal.

Thanks a lot!
Jorge

PS: By the way, my workstation has Windows 2003 installed. Should I install another OS to help performance?
Thanks

How to disable Menu / Page when navigating on click

I am using RadMenu for a site's main menu (in a master page). When I click on a menu item that takes me to another page, the menu remains active. I can highlight other menu items which can open submenus etc. Clicking menu items does not change the navigation but having the menu and page active can cause confusion.

When the page is changing (user clicks a menu item that navigates away from the page), a wait cursor should appear and the entire page should no longer be active (the user should not be able to browse through the menu or change inputs, press buttons etc.)

I have looked for a solution here, but I have not found one.

I can probably use OnItemClicking and check the navigateURL to make sure the page is changing, then overlay a transparent div on the page and set the cursor to wait...
But, I figure that either the menu may already have this feature or someone has code that has already been written and tested?

TIA

                    Dim table1 As New DataTable  
        
                    conn.Open()  
        
                    Try 
        
                        adapter.Fill(table1)

                    Return table1  
        
                End Function

How can i loop true the datagrid and check the value of "CheckBox1" with another database to set it to true or false ?

RadGrid Q3 2009 - Export To Excel Date column converts to String

Hi,

I am exporting RadGrid data to excel where I have couple of columns of type date. ExportToExcel() converts those date columns to string type. The date columns are specified as below in my RadGrids.

<telerik:GridDateTimeColumn     FilterControlWidth="120"
                                                    DataField="NearestEndDate"
                                                    DataType="System.DateTime"
                                                    EditFormHeaderTextFormat="{0:MMM dd, yyyy}"
                                                    HeaderText="Next Subscription Expires"
                                                    UniqueName="columnNextExpiryDate"
                                                    SortExpression="NearestEndDate"
                                                    DataFormatString="{0:MMM dd, yyyy}">
        <HeaderStyle Width="140px" />
        <ItemStyle Width="140px" />
</telerik:GridDateTimeColumn>

Any Idea what is the best way to set the format so that when I export this grid to excel the date column format stays same but the type of column should be date.

Regards
Div

Multiple Data Bindings

I need to bind a different database to various tabs. Is this possible, or am I going to have to string TabStrips together to get this functionality?

It seems from reading the tutorial on databinding that a TabStrip is limited to a single table.

BTW: search engine still broken.

Cheers!
Mark

adding a data point into chart

Hi there,

I am a bit confused about how to add a data point to the chart. As in MS products, I would do MyChart.Series["SeriesName"].Points.AddXY(....)

When I want to manually add a X and a Y value such as (X = "ProductA" , Y = 50) and (X= "ProductBB", Y =100), how would you do?

Thanks.

Custom Skin with RTL Grids

Hi,

I want to apply a custom skin for RadGrids so I followed the exact instructions mentioned in the documentation, but when I tried to apply it I’ve got many problems, for example:

EditCommandColumn image doesn’t appear.
problems related to images alignment (selected row, header,…etc).

Note: my grids support RTL.

The "(un)check 'Select All' " for DetailTable

Hello,

I want implement to the "(un)check 'Select All' check box automatically" code no in the MasterTable but in a DetailTable.
The difficult is on getting the id of the checkbox in the header beacause I can have either, one expanded DetailTable (i.e for the item 0 in the MasterTable), or several expanded DetailTables (i.e. for the itel 0 and for the item 6 in the Mastertable).
So i have 1, 2, 3 ... IDs.

I was trying to get the GridTableView handing the event "OnTableCreated" this way :

    
            var view; 
        
            function gettingIDs(sender, arg) 
        
            { 
        
                view=arg.get_tableView(); 
        
            }

then I reach the property "all". Here I have 9 element (even my TableView have no more than 8 columns), and I reach the element [1]
that correspond (i think) to the "GridClientSelectColumn" and I get the id (The fist column in my tableView is the GridClientSelectColumn, i dont know what is the element [0]).

Is this the correct ID?
Is there anyway to perform that in a sympler way?

thank you for the help.
