Issue
This Content is from Stack Overflow. Question asked by hank
I have a datagridview and it’s source is a bindingSource. I filter them by Id, name and date.
Also have clear button for clearing filters.
private void b_clear_Click(object sender, EventArgs e)
{
txt_filterNum.Clear();
txt_filterName.Clear();
if (File.Exists(inputpath))
{
Simulator simRead = new Simulator(inputpath);
DataTable dt = simRead.MakeDataTable();
bindingSource1.DataSource = dt;
gridView.DataSource = bindingSource1;
timeFilter.CustomFormat = " ";
timeFilter.Text = null;
timeFilter.Format = DateTimePickerFormat.Custom;
}
}
I’m having a really hard time filtering this gridview and clearing the filters.
Here I add my filter too.
bindingSource1.Filter = $"Flight_Date = #{timeFilter.Value:M/dd/yyyy}# AND {gridFilter.Columns[indexRoleName].HeaderText} LIKE '%{txt_filterName.Text}%' AND {gridFilter.Columns[indexRoleNum].HeaderText} LIKE '%{txt_filterNum.Text}%'";
I call it in textboxes_changed and datetimePicker_valuechanged.
I can’t filter the values properly, When I try to delete the filtering I have done, I can not get a reset in the datagridview.
