How to set folder browser cell type in WinForms GridControl?
Folder browser cell type
To use the FolderBrowser cell type, create custom FolderBrowserCellModel and FolderBrowserCellRenderer derived from GridTextBoxCellModel and GridTextBoxCellRenderer. The Folder Browser dialog box will be displayed in the OnButtonClicked event.
Creating CustomCellModel
C#
//Deriving GridTextBoxCellModel.
public class FolderBrowserCellModel : GridTextBoxCellModel
{
protected FolderBrowserCellModel(SerializationInfo info, StreamingContext context)
: base(info, context)
{
//Set the button bar size.
base.ButtonBarSize = new Size(20, 20);
}
//Constructor for the Derived Class
public FolderBrowserCellModel(GridModel grid)
: base(grid)
{
}
//Override the CreateRenderer() in the Base class.
public override GridCellRendererBase CreateRenderer(GridControlBase control)
{
//Return the Custom Renderer Object
return new FolderBrowserCellRenderer(control, this);
}
}
Creating CustomCellRenderer
//Deriving the GridTextBoxCellRenderer.
public class FolderBrowserCellRenderer : GridTextBoxCellRenderer
{
//FolderBrowser object declaration.
private System.Windows.Forms.OpenFileDialog folderBrowser1;
public FolderBrowserCellRenderer(GridControlBase grid, GridTextBoxCellModel cellModel)
: base(grid, cellModel)
{
AddButton(new BrowseButton(this));
//Initialize the folderBrowser1 object.
this.folderBrowser1 = new System.Windows.Forms.OpenFileDialog();
}
#region [overrides]
protected override void OnButtonClicked(int rowIndex, int colIndex, int button)
{
base.OnButtonClicked(rowIndex, colIndex, button);
if(folderBrowser1.ShowDialog()== DialogResult.OK)
{
string filePath = folderBrowser1.FileName;
}
}
}
Adding CellModel
// Add the custom cell type to the CellModels of the GridControl.
this.gridControl1.CellModels.Add("FolderBrowser", new FolderBrowserCellModel(gridControl1.Model));
// Set the cell type to "FolderBrowser"
this.gridControl1[2, 3].Text = "Browse here";
this.gridControl1[2, 3].CellType = "FolderBrowser";
