Diskuze: Nástroj na výber konkrétnejj bunky podľa stplca a riadku
V předchozím kvízu, Test znalostí C# .NET online, jsme si ověřili nabyté zkušenosti z kurzu.
Dobre, skúsim ešte raz
pridávam screen realneho formulára
rozhodol sa že to dám do datagrid a ten schovám
for (int c = 0; c < dataGridView1.Rows.Count; c++)
{
int x = dataGridView1.CurrentRow.Index;
int rowindex = dataGridView1.CurrentCell.RowIndex;
if (dataGridView1.Rows[c].Cells[0].Value.ToString() ==
textBox1.Text)
{
dataGridView1.CurrentCell = dataGridView1.Rows[c].Cells[0];
dataGridView1.Rows[x].Selected = true;
}
if (dataGridView1.Rows[rowindex].Cells[x].Value.ToString() == textBox2.Text)
{
dataGridView1.SelectedRows[rowindex].Cells[x].Value.ToString();
}
textBox3.Text =
dataGridView1.Rows[x].Cells[rowindex].Value.ToString();
}
to je môj kód - ked zadám hodnoty tak mi posúva další riadok a dalšia
bunka
nechytá mi hodnoty z textboxu 1
event - textbox leave
vie niekto ?
Nie som uplne C# programator, ale skusil som to a toto z toho vyliezlo...
namespace Test_datagridview
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
//dataGridView1.ColumnCount = 3;
dataGridView1.Columns.Add("t", "t");
dataGridView1.Columns.Add("1", "1");
dataGridView1.Columns.Add("2", "2");
dataGridView1.Columns.Add("3", "3");
var row = new string[] { "1", "1-1", "2-1","3-1" };
dataGridView1.Rows.Add(row);
row = new string[] { "2", "1-2", "2-2","3-2" };
dataGridView1.Rows.Add(row);
row = new string[] { "3", "1-3", "2-3","3-3" };
dataGridView1.Rows.Add(row);
row = new string[] { "4", "1-4", "2-4","3-4" };
dataGridView1.Rows.Add(row);
}
private void checkDGV()
{
int x = 0;
for (int c = 0; c < dataGridView1.Rows.Count - 1; c++)
{

x = dataGridView1.CurrentRow.Index;
dataGridView1.Rows[x].Selected = true;
break;
}
else

}
}
try
{
int y = dataGridView1.Columns[textBox2.Text].Index;
textBox3.Text = dataGridView1.Rows[x].Cells[y].Value.ToString();
}
