Problem with adding new rows when Filtered

Hello,

I'm developing a demo for a customer. It consist of a grid to look up for the records and a set of textboxes to edit the data.
As is just a demo, I'm working in memory with custom Business Objects (no database).
The grid allows the user for filtering. The problem is that when I add a new object to the datasource, if the grid is filtered by any column, the new empty record is not shown. If I (the end user) remove the filter, then I am able to see the just added record(s).
This is not a problem, but it's not very fancy :)
It is odd, because if I set a filter programatically this issue doesn't happen. My be it has to do with the fact that the programatic filter is done for an invisible column.
¿Any clue?
Thanks in advance,

Gonzalo

Little problem with group by

Hi,

I have a little problem with group by display.

I have :

    
            pRadGridView.MasterGridViewTemplate.GroupByExpressions.Add("Something1 as Brand format \"{1} - \",sum(Price) as TotalPrice format \"{1} €\" Group By Something1"); 
        
            pRadGridView.MasterGridViewTemplate.GroupByExpressions.Add("Something2 as Size format \"{1} - \",sum(Price) as TotalPrice format \"{1} €\" Group By Something2"); 
        
            pRadGridView.MasterGridViewTemplate.GroupByExpressions.Add("Something3 as DontCare format \"{1} - \",sum(Price) as TotalPrice format \"{1} €\" Group By Something3");

column definition

    
                        GridViewDataColumn Price_Column = new GridViewDataColumn("Price", "Price"); 
        
                        Price_Column.HeaderText = "Prices"; 
        
                        Price_Column.FormatString = "{0:N2}"; 
        
                        Price_Column.IsVisible = false; 
        
                        Price_Column.DataType = typeof(decimal); 
        
                        pRadGridView.MasterGridViewTemplate.Columns.Add(Price_Column);

The problem is.... what's displayed. I can see :

MyBrand1 - 100.00 €
    Size1 - 50.00 €
         DontCare1 - 25.00 €
         DontCare2 - 25 €
    Size2 - 50.00 €
        DontCare1 - 20 €
        DontCare2 - 30 €
MyBrand2 - 300.00 €
    Size1 - 50.00 €
         DontCare1 - 25 €
         DontCare2 - 25 €
    Size2 - 50.00 €
        DontCare1 - 20 €
        DontCare2 - 30.00 €

Sometime I can see the #.##, and I don't know why, sometime #.

I bind column like this :

    
            // subTotal is a sum a other columns, and it's int value :) 
        
            row.Cells["Price"].Value = subTotal * Math.Round(StreetPriceEuro, 2);

I change colors of "Expanders" with this code (I don't do anything else with "them") in ViewCellFormatting event

    
                            // Custom expanders colors 
        
                            if (pGridCellElement.RowInfo is GridViewGroupRowInfo && pGridCellElement.RowElement is GridGroupHeaderRowElement) 
        
                            { 
        
                                int level = ((GridViewGroupRowInfo)pGridCellElement.RowInfo).Group.Level; 
        
                                if (level == 3) pGridCellElement.ForeColor = Color.FromArgb(31, 71, 79); 
        
                                if (level == 4) pGridCellElement.ForeColor = Color.FromArgb(50, 115, 128); 
        
                                if (level == 5) pGridCellElement.ForeColor = Color.FromArgb(70, 161, 179); 
        
                                pGridCellElement.HorizontalLineColor = pGridCellElement.ForeColor; 
        
                                return; 
        
                            }

Can you explain me why sum is rounded sometime ? because, I don't mind if my value is an int, My customer want to diplay the ".00".

Thank's

Tab sizes

I would like to use 32 x 32 icons in each document tab in my docking manager.
How do I resize the tabs so that they are capable of containing the icons ?

At the moment this is just for the icons but the question really pertains to how to alter
the predefined tab sizes to fit whatever else it is I may want to fit in them.

Tabbed documents without the tabs...

I have an application with a DockingManager, AutoDetectMdiChildForms=true, and a normal windows form as MdiContainer.

When I add children forms I get tabs as expected, and a drop down menu where I can choose which tab to activate.

I have two questions:

Is it possible NOT to have the tabs, but keep the drop down menu? If my application is run on a screen with low resolution only 1-2 of the tabs are visible, so they are pointless and only generate noise.
I would like to have a Back and a Forward button to navigate through the documents, but I haven't figured out how to do this. Is it possible?

Thanks!

[Solved] SplashForm without animation

Hello, i am using the SplashForm component, but am having some problems when running my software on a virtual and/or remote client.

The splash-screen itself takes about a minute to load and you can see the transparancy changing line by line, frame by frame.

I think it is very poor graphics performance that causes the problem.

I can think of 2 possible solutions:

1. No animation at all, just a simple image.

2. Abort the animation just before the splash.Close()-call

Is any of these possible with the SplashForm-control?

Thanks in avance,

Get a reference to Conditional Formatting form

Hi,

In a grid view clicking on the menu item ConditionFormatting opens a Conditional Formatting form.
Requirement is to set it's topMost property to True and set focus on it(if opened) at the time of refreshing the grid view. But I am not getting any refrence to this form so that i can call form.TopMost = true and form.Focus() and also we can open several ConditionalFormatting form at the same time. So i want to focus the current form on which user was working recently.
i tried it this way at the time of refreshing the GridView but it sets focus to first Conditional Formatting form.

bool setFocusTogridView = true;

foreach (Form form in Application.OpenForms)

{

if (form.GetType() == typeof(ConditionalFormattingForm))

{

form.TopMost = true;

form.Focus();

setFocusTogridView = false;

break;

}

if(setFocusTogridView)

this.gridView.Focus();

Please let me know if there is some solution for this problem.

I am using Telrik version 8.2.0.0.

Regards,
Renu

RadGridView Q3 2008 is repeating or cloning columns data

Hi!

I'm using Q3 2008 version, my problem is: In design-time i added 2 columns (code, description) with its properties and datafield information. I need so because I hide some columns when it's needed. When running, fill a dataset and databind it to the datasource gridview, and when data is shown, I see 4 columns (code, description, code, description), How can I do to solve this, as in 2007 version it didn't happen to me?, thanks!

NOTE: I cannot see AutoGenerateColumns In the properties under MasterGridViewTemplate in design-time

Button not applying theme at runtime

I have 2 radbuttons on my form and i created a custom theme for them. During design time i applied the theme to the buttons and all is well. However when i view the form in runtime it defaults back to the Radforms theme which is "Office2007Black". I dont understand why this is happening. I even tried to set the theme in code

RadButtonPar_Start.ThemeName =

"Startbutton"

RadButtonPar_Stop.ThemeName = "Stopbutton"

Thanks in advance!

Select checkboxes

I'm loading data into the GridView with this statement:

.MasterGridViewTemplate.LoadFrom(command.ExecuteReader())

In the old VB6 ListView one can set the "Checkboxes" property to True and have checkboxes appear.

Is there a similar property in the RadGridView?

The checkboxes would not be bound to the database, but only used as an alternative way to select rows (.MultiSelect = True).

(With HotTracking and AlternateColors enabled, it can sometimes be a bit hard to easily see which rows are selected.)
