Im trying to fill all selected cells in a datagridview with a string that has been entered into a textbox. The datagridview i am testing with has about 1000 rows and a changing number of columns. Some of the columns can be read only and must not be changed. When i try to change the values of about 900 or more cells it takes a minute or more during which my cpu is at 100%.
What am i doing wrong? How can i improve this replacement?
Everything else works pretty fast; i.e. loading the datagridview from a text file, saving the changed data to another file etc.
Ive tried the following code:
Version 1:
Code Snippet
foreach (DataGridViewCell cell in dataGridView1.SelectedCells)
{
if (cell.ReadOnly == false)
{
cell.Value = fif.textBox1.Text;
}
}
Version 2:
Code Snippet
for (int i = 0; i < dataGridView1.SelectedCells.Count; i++)
{
if (dataGridView1.SelectedCells.ReadOnly == false)
{
dataGridView1.SelectedCells.Value = fif.textBox1.Text;
}
}
Theres no signigicant difference between the two versions.
Thank you very much for your hints.
