I have tried all this already and nothing has served. All are excluding rows and columns. What I need is to clean up the content written on them.
datagridview.datasource=null;
datagridview.resetbindings();
datagridview.Rows.Clear()
DataGridView1.DataSource=null; //Remover a datasource
DataGridView1.Columns.Clear(); //Remover as colunas
DataGridView1.Rows.Clear(); //Remover as linhas
DataGridView1.Refresh(); //Para a grid se actualizar
Hello everyone, I solved my problem like this: Clear a C # dataDrid
dataGridView1.DataSource = null;
Then just do it:
dataGridView1.Columns.Add("Coluna", "Coluna");//Acrescenta colunas
dataGridView1.Columns.Add("Coluna2", "Coluna2");//Acrescenta colunas
dataGridView1.Rows.Add("A", "B");//Acrescenta Linhas
You need to go through the Rows and clean each cell as follows:
foreach (var row in dataGridView1.Rows)
{
foreach (var cell in row.Cells)
{
cell.Value = ""; // ou qualquer outro valor que signifique 'limpar' no seu contexto
}
}
At first the other forms described above did not work out here, so ...
This removes all rows values etc., (gray pattern).
for (int i = 0; i < dataGridView1.RowCount; i++)
{
dataGridView1.Rows[i].DataGridView.Columns.Clear();
}
//LIMPAR GRID
dataGridView1.Rows.Clear();
dataGridView1.Refresh();
Generally I use DataSet (Ds) as DataSource in DataGridView (DGV) and when I want to clean the grid I use
DGV.DataSouce= Ds;
Ds.Clear(); //Retira os valores da tabela mantendo os campos
So I can both clean the DGV and update it. I hope I have helped
The lower command clears lines except the grid header
dataGridView2.Rows.Clear();
