DataGridViewColumn with multiline textboxes

How can I have/create a DataGridView having DataGridViewColumns with multiline textboxes?
(The standard DataGridViewTextBoxColumn cell are single line TextBox objects.)

Is there some way to access the properties of the underlying TextBox objects in a DataGridViewTextBoxColumn (i.e., to change the Multiline property to true)? Or, do I have to create a new class inheriting from DataGridViewColumn ?

Thanks!
Tom

Do you know when Googled 'datagridviewtextboxcell multiline'
The very first hit seemed to have an answer that would work. Or at the very least be a damned good place to start.

What's the return type of pck.Execute(); ? Void at a guess.

of course, when you rotate, a new image created that just have first frame.

1. Ok. For example I put, not *.gif, but *.png which saves its transparency in a PictureBox. However the BackColor of the PictureBox still appears behind the *.png, but what about *.gif which moves?

Yes. The same way you get it when you are not using a web service. For the moment I will assume you know how to do that since you are indicating that using a web service is the significant aspect of your problem.

well, first I want to let you know that I haven't work with this kind of problem before. here is how what I am doing so far:

WebRequest request = WebRequest.Create(webaddress);
               HttpWebResponse response = (HttpWebResponse)request.GetResponse();
               HttpStatusCode code = response.StatusCode;
               responseString = code.ToString();

but when the code is different from OK, like Address Not Found or Forbidden I am getting this error on:

System.NullReferenceException: Object reference not set to an instance of an object.
  at web_check.Service1.getStatusCode(String webaddress)

at this line:

HttpWebResponse response = (HttpWebResponse)request.GetResponse();

I would really appreciate if you will help me. Thanks, Laziale

generic comboBox method

13-Mar-09 6:45

Hello,

I am relatively new to C# and have a question regarding multiple comboBox actions. I want to create a method that modifies the list in a comboBox when another comboBox is changed. For instance, when slot1Serv is changed, an action modifies the list for slot1Adp to be the 2 items that correspond to slot1Serv's selection. The issue is that i have server comboBox's to work with (12 slotXServ comboBox's and their slotXAdp).

Can I pass the comboBox that I'm working with to the method? Can I create a custom comboBox class with the action to change another box? Am I over thinking this?

Any help would be greatly appreciated. Please also let me know if you need further information.

Maybe something like this will give you a nudge in the right direction...

This example assumes that there are 4 comboboxes, comboBoxA1, comboBoxA2, comboBoxB1, and comboBoxB2. comboBoxA1 will modify the currently selected item in comboBoxB1, and likewise for comboBoxA2 and comboBoxB2. In putting this quick example together, each of the comboboxes have the same exact items in them. You may need to adjust to fit your situation as needed.

This example requires that you stick to some sort of naming convention for the comboboxes (which it appears you do)

public Form1()
{
    InitializeComponent();

    for (int i = 1; i <= 2; i++)
    {
        // Get the "A" combobox
        string name = string.Format("comboBoxA{0}", i);

        // Get reference to the combobox using the name
        ComboBox cbo = (ComboBox)this.Controls[name];

        // Set the tag property to the index of this combobox
        cbo.Tag = i.ToString();

        // Assign an event handler to that comboboxes SelectedIndexChanged event
        cbo.SelectedIndexChanged += new EventHandler(this.ComboBoxA_SelectedIndexChanged);
    }
}

private void ComboBoxA_SelectedIndexChanged(object sender, EventArgs e)
{
    // Get reference to the combobox that caused this event to fire
    ComboBox cboA = (ComboBox)sender;

    // Get the index out of its tag property.  This is so we know how to find the associated "B" combobox
    string index = cboA.Tag.ToString();

    // Get the "B" combobox
    ComboBox cboB = (ComboBox) this.Controls[string.Format("comboBoxB{0}", index)];

    // Set the selected index of the "B" comboBox to the "A" comboBox
    cboB.SelectedIndex = cboA.SelectedIndex;

}

Thanks for your help. Now when I run the code below, when it gets to the second comboBox (slot{}Adp), I get a null exception. Is the "this.Controls[]" actually referencing the original CB, or is it just loading its behavior?

private void adapterSelect(object sender, EventArgs e) {
    //// Create references to original comboboxes
    ComboBox cbServ = (ComboBox)sender;
    ComboBox cbAdp = (ComboBox)this.Controls[string.Format("slot{0}Adp", cbServ.Tag.ToString())];

    // This line returns the null exception
    cbAdp.Text = "test";
}

Hello

I'm using a class of about 30 different parameters

I find very easy to use the little method below to automaticaly serialize and save those parameters

Unfortunately it does not work for Font
Is there some trick to use to wrap fonts the same way ?
Or do I have to serialize ALL elements one by one manualy ?

Tanks for any help

      // *******************************************************************************************
private void SaveTemplate()
{
  XmlSerializer xs;
  StreamWriter sw;
  string TemplateFile = "d:/tmp/xxx.xml";
  if (TemplateFile.Length <= 0)
  {
    return;
  }
  xs = new XmlSerializer(typeof(C_PrintSettings));
  using (sw = new StreamWriter(TemplateFile, false, Encoding.Default))
  {
    xs.Serialize(sw, Document.PrintSettings);
    sw.Close();
  }
}

This is a classic case of using technology that you have not studied and therefore do not understand it.

They hide that information in the documentation.
