Hi,

I want to handle keypresses in your grid control. I added two virtual functions OnGbwAnalyzeCellKeyEvent and OnGbwAnalyzeCellSysKeyEvent to the class derived from CExtPPVW<CExtGridWnd>. However in debug mode I did not hit to these functions. Ie Keystrokes are not processed. Perhaps in the control you need to install some flags. Can you give some working samples in which processed pressed?

Can text cells in the grid have a transparent background? I tried cell.Style.BackColor = Color.Transparent, but that did not work. thanks

Hello,

I have a couple of situations where i have a cell pointer and i need to retrive the coresponding grid row or column.

Example:

CExtGridCell* pCell;

Is there anything like this?

    int rowNb = m_wndGrid->GetCellRow(pCell);

If this functionality is not  supported maybe there is an

The CExtGridWnd grid control does not contain any grid cells. It only allows grid cells to be painted, hit-tested, edited, resized and etc. All the grid controls are stored in a data provider component, which is internal and invisible. This architecture is similar to MFC’s document/view architecture. The grid control is like a view window and the data provider is like a document. It’s possible to make more than one grid control using the same data provider containing the same two dimensional array of grid cells. So, the grid cells does not know anything about their location inside grid window. The grid cells even don’t know whether they are displayed at least in one grid window. That is why most of methods in grid cell classes have parameters with pointer/reference to grid control and row/column numbers. As a result, if a grid cell class is notified about anything via some of its virtual methods, this method knows grid window pointer/reference, cell coordinates and other/additional event information via method parameters. The same is related to virtual methods of CExtGridWnd class. Your code always knows where is the grid cell located and which event happened.

Hi

I’m trying to install ElegantGrid on a machine running Windows Vista Business and Visual Studio 2005 (with Vista updates).

I run the installer as Administrator, the following screen appears but no progress is made.

When I look in the Task Manager, the devenv.exe and a .tmp installer process are running as well as a dialog entitled "Information Window".

Any ideas on what might be causing this?

All the best

Ivan

I should also point out that there are thousands of temporary files in my temp folder after forcefully closing the setup program.



Regards,

Ivan

I am curious to know what you guys use in-house w.r.t automation tools.

I am looking to interrogate the grid control using silktest but alas it is a difficult task.

Do you recommend some other tool or have you guys created any hooks that help you work with such tools as SilkTest and QTP.

I have also downloaded testcomplete (i.e. another windows automation tool) but alas the same object recognition issues.





Thanks

Peter.

i am using ElegantGrid(unboundgridcontrol) for Retrieving more data’s from database.But its taking long time to get retrieve.How can i solve this problem?



Can anyone please help me out



 

I tried to load data’s from database to boundgridview control in VB.Net.

Below is the code,

    Dim oleDbConnection As OleDbConnection = New OleDbConnection(connectionstring)

        Dim oleDbSelectCommand As New _

           OleDbCommand(select Query, oleDbConnection)

        Dim dataAdapter As New OleDbDataAdapter

        dataAdapter.SelectCommand = oleDbSelectCommand

        Dim dataSet As New DataSet(tablename)

        dataAdapter.Fill(dataSet)

        Dim table As DataTable = dataSet.Tables(0)

        BoundGridControl1.DataSource = table



The data’s are not getting added to the BoundGridviewControl.Please send me any  sample code in VB.Net to bound the data’s to grid view control.



Awaiting your reply

Here is the article that should help you: Data Bound Grid. Did you read it? If after reading it, you still encounter the above problems, please let us know.

Tengo la licencia de este producto como podran observar arriba, en el stack trace.

Honestamente, me gustan las prestaciones que ofrece su producto pero me siento frustado por no tener una forma facil de dominarlas, aunado a este tipo de mensajes de error que me dejan con desconfianza como para poderlo integrar en mis desarrollos... Quisiera saber si existe algun parche o algo por el estilo que corrijan los bugs que se han identificado, ademas de un manual de usuario (aunque sea en ingles) que me pueda guiar para explotar al maximo su producto de forma clara y sencilla.

Thank you for reporting this problem. We will look into it. But it is really strange. We have a lot of customers in Korea and nobody reported this bug before. Anyway we will try to find out what is wrong.

Thank you.

Of course, in order to evaluate Elegant Grid, you can use it for 60 days. Thank you for reporting the problem. Would you let us know some more details about the problem?

1. What is the OS (and service pack if any) you are running?
2. What is the language of the OS, English or Korean?
3. What Visual Studio(s) is(are) installed?

Thank you again. With your help, we hope to fix the problem quickly.

Hi! I am Gridcontrol User.

what can i do?

Hi, we are using the Elegant grid in an application that requires screen update, but when we try to update the datasource of a Bound Grid it keeps the old data and add the new one, kind of duplicating columns.

We have tried to clean the datasource with .Datasource = Nothing, but this causes an

"Object Reference Not Set to an Instance of an Object" error.

How can we proceed?

Thanks so much

Marcos

Unfortunately we failed to reproduce this problem. Could you send us a project that illustrates the issue?

Hi, I’ve just sent an e-mail with the sample. The subject was "RE: Cleaning the Datasource property in a Bound Grid".

But I’ve sent the mail from wsouza@bulltick.com ’cause my mail has problems...

Thanks in advance,

It semms that the mail doesn’t allow zip files so I’m sending a text file

From a click button, I try to consent to the value of a cell with DataValue, but an error exists

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
UnboundGridControl1.Cell(1,1).DataValue <-----------ERROR
EndSub

got it, sorry, changed datarow for row when adding references

tried this example to modify a column value depending on other comboboxcell but can’t
cause it says


Dim _TotalByColumnRow As Elegant.Ui.Grid.Row
_TotalByColumnRow = grdU.Rows(1)
Dim totalByColumnCell As Elegant.Ui.Grid.Cell = _TotalByColumnRow.Cells(grdU.Columns(1))

_TotalByColumnRow.Cells(grdU.Columns(1))

’Cells’ is not a member of ’Elegant.Ui.Grid.Row’.    

what reference i’d have to add to use object cells?

thanks

In the event click, intent to save to a file in particular the value of some cell.

As I can consent to the value of a cell of an UnboundGridControl from code?

You can use Cell.DataValue and Cell.DisplayValue properties for that.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

UnboundGridControl1.Cell.DataValue
EndSub

Impossible, it indicates me ERROR

greetings.
My question is, like I can set text to a cell of the RowHeaderColumn

There is no default implementation for text in row header cells but you can render it yourself using the ICellContentViewer interface. All you need is to implement two methods of this interface: Measure() and Paint(). Then you should set the CellStyle.CustomContentViewerType property of a particular cell style to the type of class that implements the methods in order to apply your custom viewer. You can learn how to make custom cell viewer from the following samples in Simple Demos set: Search, Product Photos, Multithreading, and Graphs.
