When using the detail view, the default column width is too wide. Is it possible to set the width before the dialog is shown?

I would also prefer that the column header text be left justified.

The first image shows how it looks now and the second image shows how I want it to look.

Hello, Jeff,   

Note that the file dialogs use a RadListView in the explorer control for displaying the folders/files. If you need to customize the alignment of the Name header cell, it is suitable to use the CellFormatting event that RadListView offers.

As to the column's width, it is necessary to specify the Width of the column in the SaveFileDialogForm.Shown event. Please refer to the following code snippet:

public RadForm1()
{
    InitializeComponent();
 
 
    this.radSaveFileDialog1.SaveFileDialogForm.Shown += SaveFileDialogForm_Shown;
    this.radSaveFileDialog1.ShowDialog();
}
 
private void SaveFileDialogForm_Shown(object sender, EventArgs e)
{
    this.radSaveFileDialog1.SaveFileDialogForm.ExplorerControl.FileBrowserListView.CellFormatting -= FileBrowserListView_CellFormatting;
    this.radSaveFileDialog1.SaveFileDialogForm.ExplorerControl.FileBrowserListView.CellFormatting += FileBrowserListView_CellFormatting;
    this.radSaveFileDialog1.SaveFileDialogForm.ExplorerControl.FileBrowserListView.ViewType = ListViewType.DetailsView;
    this.radSaveFileDialog1.SaveFileDialogForm.ExplorerControl.LayoutType = Telerik.WinControls.FileDialogs.LayoutType.Details;
    this.radSaveFileDialog1.SaveFileDialogForm.ExplorerControl.FileBrowserListView.Columns["Label"].Width = 100;
}
 
private void FileBrowserListView_CellFormatting(object sender, ListViewCellFormattingEventArgs e)
{
    if (e.CellElement.Data.HeaderText == "Name")
    {
        e.CellElement.TextAlignment = ContentAlignment.MiddleLeft;
    }
    else
    {
        e.CellElement.ResetValue(LightVisualElement.TextAlignmentProperty, Telerik.WinControls.ValueResetFlags.Local);
    }
}

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
