Hi,
Please let me know how to add a filter for DataGridView so that the user can enter the filter condition in the corresponding column header to filter the rows that match the condition.

I am new to C#. Requirement is simillar to how it is in Mercury Quality center or TestDirector tools.

Hope the question is clear..

Thanks & Regards,
Dhana

Hi,

Since the DataTable source is assigned to DataGridView, you can filter the DataTable by using
DataTable.DefaultView.RowFilter="ColName=" + ColValue
It will automatically apply to the DataGridView

If this is a bound DataGridView, you are not allowed to add rows. Hence you will need to extend the DataGridView if you need a filter like Quality center.

A quick and dirty (and may be "not recommended") way is:
1. Provide padding the headercell.
2. Add a textbox to the DataGridView at the location right above the first row.(You will need to play with the location of the textbox)
3. Handle its TextChanged event and set the RowFilter property of the datatable you have.

A better solution IMO will be to have a button and display a modal window where in user can apply filter.

It's not necessary to be so stupid, either, but people manage it. - Christian Graus, 2009 AD

Hi All,

I am having problems adding a new row to a datagridview control in my form. I have a simple form
a datagridview. When the user types in an item number at columen one , the system will populate the datagridview with the relevant data from the database.

Try out the following code -

dataGridView1.AlloUserToAddRows = True;

Keep me posted if this resolves your problem. Smile | :)

Take a look at this[^] thread. Although it is about a ComboBox in a DGV the same principle can be applied to hooking an event for a DataGridViewTextBox (or whatever you are using). All you have to do is decide which event is most appropriate for your needs.

IIRC they are in a subfolder of the common folder in the Visual Studio install. If you did a custom install, you may not have selected them so you will have to run set up and modify.

If you are running an express version, then they do not exist for you.

Hi all.
I wanna convert a string ( eg : "0110101" ) to equal of it in Binary ( 0110101 )

Could you please guide me ?
Thanks.

DaveyM6910-Aug-09 23:17

You can use:

int i = Convert.ToInt32 (binaryString, 2);

If you are doing a lot of this in your application you may find my article[^] useful.

I really need to revisit that article. It served the requirements that I had at the time so that's as far as I went with it, but it could be more useful with a little work. I was resonably new to C# then too so there are probably a few things that could do with refactoring.
