I'm not overly familiar with winforms and the correct way to filter data on a datagrid view. But something like the following may help you.

var filteredItems = Items.Where(row=>textbox1.Lines.Contains(row.FilterColumn));

you may want to do something more to allow for ignoring the case of what you are filtering on, but filteredItems should be a step towards what you want.

With what exactly? Where will the filtering take place, on the server or on the client-machine? And how do your lines in the textbox match up with the tablenames?

Perhaps if you showed us some code that explains how you load the data in there, we might hint what the most appropriate solution could be.

Let's assume your DataGridView is already full of Data, in Cells, organized in Rows and Columns, naturally.

Now for each line of text in the multi-line TextBox:

Exactly how do you want to use that to filter either certain Cells, or certain Rows, or certain Columns, in your DataGridView ?

What exactly does "filter" mean here: to hide something that does not "match," or ... ?

What have you tried so far ?

I do think if you can write up your problem more clearly, that it would be better, for you, if you posted it in the QA section.

Thanks everybody for helping! And sorry for late answer.

Bill , as you're saying i have a datagridview full of data.
What I want is show the datagridview rows that match with the lines in the multiline textbox

For example: my datagridview have two columns: Name and Last Name to say something...
In the textbox I type in the first line John and in the second line I type Mary.
I want the datagrid to show me only the rows that have these names.

And if I keep typing in others lines keep doing the firter or search...
I hope I explained better now... Thanks in advance!

Open Form From another Project with its Name

Hi to All
I Have a Solution in C# that have 4 projects in it.
I want to Showing Forms of Other projects when I have
its Name(Such as Project2.Frm_Log).
I use this code:

string formTypeName = "frm1";
Type formType = Type.GetType(formTypeName); // Should also include namespace, if frm1 is inside a namespace.
Form f = (Form)Activator.CreateInstance(formType);
f.Show();
//From "Open Form at Runtime" Post

but the value Of formType will be null.
please help me.

Eddy Vluggen2-Aug-12 23:34

You don't need reflection to do that. First, lay a reference from the project where you want to use the form, to the project where the form to be used is located. Should be a menu around there somewhere, saying something like "add references".

Then it would be something as simple as this;

using System;
using System.Windows.Forms;
using Project2; // also required!

class MainForm: Form
{
    public MainForm()
    {
      //
    }
    public ShowTestForm()
    {
      // simple version
      // Project2.frm1 theForm = new Project2.frm1();

      // version if you want bonus-points
      using (var f = new frm1())
      {
          if (DialogResult.OK != f.ShowDialog(this))
          {
             throw new Exception ("Replace the user until someone is brave enough to click OK!");
          }
      } 
    }
}

Hope it helps a bit Smile | :)

thank you for replying , but the form name is in string format and then your code dosnt work.

using (var f = new frm1())

Eddy Vluggen3-Aug-12 0:18

Would you care to explain why it needs to be in a string format? If not, a simple strategy-method would solve the problem;

public Form BakeMeSomeNiceForm(string Whut)
{
  switch (Whut)
  {
     case "frm1": return new frm1;
     case "frm2": return new frm2;
     default: throw new UnknownSwitchValue(Whut);
  }
}

Use the method where your string is right now, it'll return the form requested by the string. Might require some casting.

the solution you have proposed here seems a much better way of doing things, every time i try to think of a reason for needing to just be able to work with a string i come back to what is wrong with just calling a factory method.

not sure what the requirement is but this code should work for you, not sure it is the best or right way but was the quickest answer i could write

string formName = "ToCreate.Form1";
var asm = Assembly.Load("ToCreate");
Type formType = asm.GetType(formName);
Form f = (Form) Activator.CreateInstance(formType);
f.Show();

the control libary is called "ToCreate", you need to pass the full name including assembly to the asm.GetType method, i also included a reference from the main project to the project containg form1.

Eddy Vluggen3-Aug-12 0:58

If he referenced the project, it'd already be loaded. Next, this assembly will not be unloaded. Then there's the slower Activator.

I didn't feel like changing that, as I'd use strong-typing to get the initial string;

string formClassName = typeof(frm1).Name;

Depends; if it has to be a plugin, I'd understand. For all other problems, I'd go for the simple solution.
