 # How to set folder browser cell in winforms gridcontrol
-This example demonstrates how to set folder browser cell in winforms gridcontrol
+
+This example demonstrates how to set folder browser cell in [WinForms GridControl](https://www.syncfusion.com/winforms-ui-controls/grid-control).
+
+To use the `FolderBrowser` cell type, create custom `FolderBrowserCellModel` and `FolderBrowserCellRenderer` derived from [GridTextBoxCellModel](https://help.syncfusion.com/cr/windowsforms/Syncfusion.Windows.Forms.Grid.GridTextBoxCellModel.html) and [GridTextBoxCellRenderer](https://help.syncfusion.com/cr/windowsforms/Syncfusion.Windows.Forms.Grid.GridTextBoxCellRenderer.html). The Folder Browser dialog box will be displayed in the [OnButtonClicked](https://help.syncfusion.com/cr/windowsforms/Syncfusion.Windows.Forms.Grid.GridCellRendererBase.html#Syncfusion_Windows_Forms_Grid_GridCellRendererBase_OnButtonClicked_System_Int32_System_Int32_System_Int32_) method.
+
+### 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
+
+``` c#
+//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
+
+``` c#
+// 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";
+```
