Transfer where? Also, winforms or webforms? What have you tried until now?

bora1891 9-Oct-14 8:27am

Sorry,I forgot to write which forms..I work in c# winforms and my database is sql..

Sinisa Hajnal 9-Oct-14 8:38am

Thank you, now please use Improve question link and give us more detailed description and some code. Thank you

bora1891 9-Oct-14 9:12am

I use this code but I didn't transfer more than one row when I select 2 rows code will be accept the last one and show the last one in the datagridview

Int32 ID = Convert.ToInt32(dataGridView1.Rows[dataGridView1.CurrentRow.Index].Cells[1].Value.ToString());
MessageBox.Show("ID" + ID);
DataTable table = new DataTable();
using (SqlConnection conn = new SqlConnection(@"Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\Dorana.mdf;Integrated Security=True;User Instance=True;Pooling=False"))
{
string SQL = @"Select * from rezerve Where ( rezerveID = @rzveID);";
SqlCommand cmd = new SqlCommand(SQL, conn);
cmd.Parameters.AddWithValue("@rzveID", ID);

conn.Open();
table.Load(cmd.ExecuteReader());
conn.Close();
}
rzve rzrv= new rzve();
// DataGridView dgv1 = new DataGridView { Dock = DockStyle.Fill };
rzrv.Controls.Add(dataGridView1);
rzrv.dataGridView1.DataSource = table;
rzrv.Show();

rzrv.dataGridView1.Columns["name"].HeaderText = "Name";
rzrv.dataGridView1.Columns["surname"].HeaderText = "Surname";
rzrv.dataGridView1.Columns["gender"].HeaderText = "Gender";
rzrv.dataGridView1.Columns["date"].HeaderText = "Date";

Solution 3

C#

protected void btnClick(object sender, EventArgs e) {
string ids = String.Empty;
    foreach (DataRowView drv in DataGridView1.Rows) {
        if (drv[0].Checked) { // <-- you might have to cast here
ids += drv["rezerveID "];
        }
            // your query, ids goes into @rzveID placeWHERE rezerve_id IN @rzveID

    }
}

You might consider keeping checked row indexes collection on CheckBoxCellClick (use CellContentClick or checkedChange or some such). In that case you're not iterating through all rows in the grid like the above code, but you're introducing at least one more object (collection), event (checkedChanged) and logic for adding and removing the items.

I would go with simpler solution.

If this helps please take time to accept the solution. Thank you.

Thnxs for all but I tried your solution and I didn't solve my problem.I think my problem is ID..When I use ID in my query,program always will be accept the last selection because I select more than one rows with checkboxes but it will accept the last one how can I solve my problem ?..Please give an suggestion
Again thnxs for your help :)

Sinisa Hajnal 10-Oct-14 6:11am

It seems we don't understand each other. Your code selects always single row. If you want to select more of them, you HAVE to iterate through selected rows...

What you need to do is create a list of selected IDs and modify your query like this:
Where ( rezerveID IN @rzveListID);
(where of course rzveListID is the list created in button click as above 1, 2, 3, 4, ..., n)

If you take time to describe your problem in more details, so that everyone understand what your problem is, the help will be that much faster. Right now, it is not clear that the code above is the source of your problem since you never once said WHAT DO YOU MEAN by TRANSFER selected rows...and there were questions "transfer where" and "whaddaya mean" etc...

bora1891 10-Oct-14 6:39am

Hajnal,yes I mean tranfer selected rows.
My problem is to transfer data by multiple selection.For example, users makes multiple selection with checkboxes in the table and that you have selected the rows in the DataGrid will show in another form Datagrid in WindowsForms.So I used this code to transfer data from another form's datagrid.I succeed it but I didn't multiple transfer data.This is my code of transfer data.

Int32 ID = Convert.ToInt32(dataGridView1.Rows[dataGridView1.CurrentRow.Index].Cells[1].Value.ToString());
MessageBox.Show("ID" + ID);
DataTable table = new DataTable();
using (SqlConnection conn = new SqlConnection(@"Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\Dorana.mdf;Integrated Security=True;User Instance=True;Pooling=False"))
{
string SQL = @"Select * from rezerve Where ( rezerveID = @rzveID);";
SqlCommand cmd = new SqlCommand(SQL, conn);
cmd.Parameters.AddWithValue("@rzveID", ID);

conn.Open();
table.Load(cmd.ExecuteReader());
conn.Close();
}
rzve rzrv= new rzve();
// DataGridView dgv1 = new DataGridView { Dock = DockStyle.Fill };
rzrv.Controls.Add(dataGridView1);
rzrv.dataGridView1.DataSource = table;
rzrv.Show();

rzrv.dataGridView1.Columns["name"].HeaderText = "Name";
rzrv.dataGridView1.Columns["surname"].HeaderText = "Surname";
rzrv.dataGridView1.Columns["gender"].HeaderText = "Gender";
rzrv.dataGridView1.Columns["date"].HeaderText = "Date";

Yes, yes, you mean transfer selected rows, but transfer WHERE!? Into the database, into another grid, what?

If it's just a matter of transfer to another grid, you can use ImportRow into that other grid datasource.

Like this:
foreach loop
newGrid.DataSource.ImportRow(originalGridRow) -- ImportRow is DataTable method so you'll need to cast accordingly.

And did you try my suggestion of creating list of IDs and then getting them from the database?

bora1891 10-Oct-14 8:59am

I want to transfer into the another grid.But the grid has the other form.
And I tried your suggestion but I get an error.The Error message in the error list;
'object' does not contain a definition for 'Checked' and no extension method 'Checked' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?).
Can you explain to me your this suggestion I don't know this way :/

Like this:
foreach loop
newGrid.DataSource.ImportRow(originalGridRow) -- ImportRow is DataTable method so you'll need to cast accordingly

Sinisa Hajnal 10-Oct-14 9:08am

That is why I commented that you need to cast it. You can call ImportRow only on DataTable. If your datasource is DataSet you have to cast it into dataset, use ds.Tables[0] or something, similar for bindingSources, DataTables and other various types. You can use ImportRow only if you can get DataTable out of your datasource.

Similarly for Checked property. You have to cast it into CheckboxCell or whatever the exact type is.

bora1891 12-Oct-14 7:52am

Sinisa,
Can you give any code to understand well?
And maybe you gave the code solves my problem :)

Sinisa Hajnal 13-Oct-14 1:53am

I'm sorry, I won't. This is YOUR problem. The above describes in details what you need to do. Casting is easily googled if you don't know what it is (which I doubt since you obviously know some C#). Same for string concatenation. Only thing that was troubling is your query (which is solved by the concatenation of IDs) and for each which is solved in the solution. I will expand the solution with ID concatenation however.

bora1891 13-Oct-14 7:29am

Ok sinisa,thxs for interesting my subject

My Project uses datagridviews. Instead of using checkboxes the user can select rows using the row headers (Ctrl+Shift for multi-select).

C#

this.dataGridView1.SelectionChanged += new EventHandler(dataGridViewDevices_SelectionChanged);


void dataGridView1_SelectionChanged(object sender, EventArgs e)
{
            DataGridViewSelectedRowCollection rows = this.dataGridViewDevices.SelectedRows;
            int n = rows.Count;

//copy items

for (int i = 0; i < n; i++)
{
object item = rows[i].Cells[0].Value; //get cells by row index or Column Name
//copy to new grid or datatable bound to other grid                      
}

}
