Well, sorry to tell, the databinding works on dataset, at least on mine. The message box will display the changed value:

private void button1_Click(object sender, EventArgs e)
{
    string s = "user id=sa;password=PASSWORD;initial catalog=DATABASENAME;data source=SERVERNAME;timeout=90";
    IDbConnection con = new System.Data.SqlClient.SqlConnection(s);
    IDbCommand cmd = con.CreateCommand();
    dataSet = new DataSet();
    IDbDataAdapter adapter = new System.Data.SqlClient.SqlDataAdapter();

    cmd.CommandText = "Select * from Customers";
    adapter.SelectCommand = cmd;
    adapter.Fill(dataSet);

    if (dataSet.Tables[0].Rows.Count > 0)
    {
        this.textBox1.DataBindings.Add("Text", dataSet, "Table.CompanyName", false, DataSourceUpdateMode.OnPropertyChanged, string.Empty);
        propertyGrid1.SelectedObject = dataSet.Tables[0].Rows[0];
    }
}

private void button2_Click(object sender, EventArgs e)
{
    MessageBox.Show(dataSet.Tables[0].Rows[0]["CompanyName"].ToString());
}

What database are you using? My example was using SQL 2005.

You aren't using WPF are you?

As for 22 columns, that's not a lot. Poke tongue | ;-P

Write a simple code generator, read from a CSV file and generate the class with the get/set.

I'll look into it.

Besides, that is stiull a workaround.

The point is, simple binding should work. Even the parse routine gets called when I change a value - it just doesn't update the dataset at the end of parse!!

Have you tried dragging the fields onto your form from Server Explorer? That seems to produce bound textboxes that work, then you can look at taking it further from there.

Filtering a DataGridView bound to a BindingSource

Hi,

I have a DataGridView whose DataSource is BindingList of objects:

this.peerList = new BindingList<PeerInfo>();
this.dataGridView1.AutoGenerateColumns = true;
this.bindingSource = new BindingSource();
this.bindingSource.DataSource = this.peerList;

this.dataGridView1.DataSource = this.bindingSource;

I have found guides online of how to set up this filtering, but they only work if the source is a DataTable.

Is there a way to mimic this behavior on a BindingList?

Thanks,

klk

(Also, sorry for not using code tags, as they made the generics disappear).

madness ? this.isSparta = true : this.isSparta = false;

That is not the application root. That is two levels above the application root.

That is because the XML file is most likely in your project, not the application root.

Don't hard code file paths (relative or absolute) in your application.

Put file paths in the config file and find out from there.

Also, if the XML files are supposed to be in the application root folder then you might want to tell Visual Studio that so that it can copy the XML files to that location when you run your application.

To do that, right click the XML file in the Solution Explorer. Select "Properties" in the context menu. In the Properties ensure that "Build Action" is set to "Content" and that "Copy to Output Directory" is set to either "Copy if newer" or "Copy Always"

Display the full file path and then see if the file is there. I'll bet it is a relative path and its wrong.

Spell Checking with C#

I have a windows application, where i should find the spelling mistakes from a list of xml files.I used the following code and am able to list the misspelled words. The problem is, I have more than 1000 such xml files. Everytime a spell check is happening in an xml file, one Microsoft Word window is opening. To spell chek 1000 such xml files, 1000 word windows are opened at the sametime. But still, i have closed all those windows using code. Eventhen, every window is opened and then it is getting closed. This is visible to the user. Is there any way to hide the Microsoft Word window to the user? Or can i do spell checking without opening word? Please suggest me.

Thanks in advance.

The code i used is

Word._Document doc= app.Documents.Add(ref template,ref newTemplate,ref documentType,ref visible);
           app.Visible=false;
           doc.Windows.Application.Visible=false;
           doc.Words.First.InsertBefore(strDesc);
           Word.ProofreadingErrors we=doc.SpellingErrors;
           iErrors=we.Count;
           for (int i=1; i<=we.Count;i++)
               strErrArray.Add(we.Item(i).Text);
           app.Documents.Close(ref SaveChanges,ref OriginalFormat,ref RouteDocument);

Please suggest me a good solution.

Control suggestion

I need to display a list which have a text and a button in each row. Which control will be good for this ?

I did this by creating a custom control that wraps TableLayoutPanel. I have create another control which has Label and a Button. Second control will be added to each row in the TableLayoutPanel. Inner control's events are handled by the control which wraps TableLayoutPanel and this control's events are handled on the form. Is this right approach ? Or is there any similar kind of controls available ?

All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia

If I am understanding your question correctly, a TableLayoutPanel having buttons in one column and textboxes in other alone would work.

Discarding Keyboard-Events for GUI

How is this related to Windows forms?

Hi!

I have an application that has a keyboard-listener (system-hook).
It is being notified on any keyboad-event, even if the app-windows is not active.
As far as that it works as designed.

My problem is, that it is possible, that someone pushed the space-bar or the cursor-buttons, what effects on the GUI, e.g. to buttons, list-views, etc... So if someone presses the curser-buttons a highlight wanders around my gui. And if the spacebar is hit and a button was highlighted this button will be pressed. This is what i´d like to avoid.

What i´d like to have is to make the gui ignore these keyboard inputs (except textboxes, where you need the keyboard).

Is there a way of making the GUI-elements not react on keyboard-actions?

Thanx

J.

Handle the KeyDown event and set SupressKeyPress to True.

This didn´t work the way i need it.

For testing i just built a small App, containing a form with 9 buttons.
I handled the KeyDown-Event and set SupressKeyPress to true, but i still could navigation through my buttons with the cursor-keys and click them using the space-bar. I checked that with handling the Click-event, which behaved exactly like it did without SupressKeyPress set to true.

I guess that this keyboard events are handled BEFOR they even arrive at my KeyDown-handler.
The question is, if this prior handling can be suppressed in any way...

I tried the same and found one strange thing. Here it is:
I have three buttons and a textbox. On buttons click, button name will be displayed in the textbox. If I put breakpoint at keydown event, click event is not fired. But remove the breakpoint and its fired. Confused | :confused:

I guess you will need to override WndProc method to achieve your task.
