How to get the tags when the style.Tag is set through PrepareViewStyleInfo or QueryCellInfo events?
When a tag of a cell style is set through an event, that tag value cannot be retrieved using this.grid[0,1].Tag. Instead, you can make use of the GetView method in WinForms GridControl for retrieving the tag in such cases.
this.gridControl1.PrepareViewStyleInfo += gridControl1_PrepareViewStyleInfo;
private void gridControl1_PrepareViewStyleInfo(object sender, GridPrepareViewStyleInfoEventArgs e)
{
if (e.RowIndex == 0 && e.ColIndex == 1)
{
e.Style.Text = "Header1";
e.Style.Tag = "Test tag";
}
}
private void button1_Click(object sender, EventArgs e)
{
object obj = new object();
obj = this.gridControl1.GetViewStyleInfo(0, 1).Tag;
MessageBox.Show(obj.ToString());
}AddHandler Me.gridControl1.PrepareViewStyleInfo, AddressOf gridControl1_PrepareViewStyleInfo
Private Sub gridControl1_PrepareViewStyleInfo(ByVal sender As Object, ByVal e As GridPrepareViewStyleInfoEventArgs)
If e.RowIndex = 0 AndAlso e.ColIndex = 1 Then
e.Style.Text = "Header1"
e.Style.Tag = "Test tag"
End If
End Sub
Private Sub button1_Click(ByVal sender As Object, ByVal e As EventArgs)
Dim obj As New Object()
obj = Me.gridControl1.GetViewStyleInfo(0, 1).Tag
MessageBox.Show(obj.ToString())
End SubThe output is as follows.
