Hello Mark,

Thank you for writing.

To achieve the desired functionality, you should create a custom grid behavior in the following way:

class MyBehavior : BaseGridBehavior

{

public override bool ProcessKeyDown(KeyEventArgs keys)

{

if (keys.KeyData == Keys.Enter && this.GridControl.IsInEditMode)

{

this.GridControl.GridNavigator.SelectNextColumn();

}

return true;

}

Then, simply assign this custom behavior to your grid:

radGridView1.GridBehavior = new MyBehavior();

I hope this helps.

Dear

I tried the following code :

Private Sub RadGridView1_PreviewKeyDown(sender As System.Object, e As System.Windows.Forms.PreviewKeyDownEventArgs) Handles RadGridView1.PreviewKeyDown
If e.KeyData = Keys.Enter Then
Me.RadGridView1.GridNavigator.SelectNextRow(1)
End If
End Sub

but after editing the cell, I need to Press Enter twice (2 times) in order to move to the second row.
there's a solution ?
And lets say I have I have 3 columns, and just second column is editable, how to make it by default cell selective, in another term, wherever user click in any cell, or press enter in any cell, just cell of column 2 be selected.

Thanks

Hi Rawad,

Thank you for writing.

You have to press enter key twice because the first time you do it, the grid will go out of edit mode and the next one will move the selection. The solution provided with the previous post is suitable for both of your requirements. Feel free to use it.

If need be, you can use our free online C# to VB converter: http://converter.telerik.com/.

I hope that you find this information useful.

yes dear , thanks a lot, it's working well.

and another solution can be:

Private Sub RadGridView1_PreviewKeyDown(sender As System.Object, e As System.Windows.Forms.PreviewKeyDownEventArgs) Handles RadGridView1.PreviewKeyDown
If e.KeyData = Keys.Enter Then
If RadGridView1.CurrentRow.Index + 1 = RadGridView1.Rows.Count Then
Me.RadGridView1.GridNavigator.SelectFirstRow()
Me.RadGridView1.GridNavigator.SelectFirstColumn()
Else
Me.RadGridView1.GridNavigator.SelectNextRow(1)
Me.RadGridView1.GridNavigator.SelectFirstColumn()
End If
End If
End Sub

Private Sub RadGridView1_CellEndEdit(sender As System.Object, e As Telerik.WinControls.UI.GridViewCellEventArgs) Handles RadGridView1.CellEndEdit
If RadGridView1.CurrentRow.Index + 1 = RadGridView1.Rows.Count Then
Me.RadGridView1.GridNavigator.SelectFirstRow()
Me.RadGridView1.GridNavigator.SelectFirstColumn()
Else
Me.RadGridView1.GridNavigator.SelectNextRow(1)
Me.RadGridView1.GridNavigator.SelectFirstColumn()
End If
End Sub

Hi Abdul,

This can be achieved by using custom row behavior which allows you to handle the enter key. You can use the Tag property to store the tab indexes. Here is a sample implementation:

public partial class RadForm1 : Telerik.WinControls.UI.RadForm

{

public RadForm1()

{

InitializeComponent();

radGridView1.DataSource = GetTable();

BaseGridBehavior gridBehavior = radGridView1.GridBehavior as BaseGridBehavior;

gridBehavior.UnregisterBehavior(typeof(GridViewDataRowInfo));

gridBehavior.RegisterBehavior(typeof(GridViewDataRowInfo), new CustomGridDataRowBehavior());

}

protected override void OnLoad(EventArgs e)

{

base.OnLoad(e);

int count = 100;

foreach (var row in radGridView1.Rows)

{

foreach (GridViewCellInfo cell in row.Cells)

{

cell.Tag = count--;

}

static DataTable GetTable()

{

DataTable table = new DataTable();

table.Columns.Add("Dosage", typeof(int));

table.Columns.Add("Drug", typeof(string));

table.Columns.Add("Name", typeof(string));

table.Columns.Add("Date", typeof(DateTime));

table.Rows.Add(25, "Indocin", "David", DateTime.Now);

table.Rows.Add(50, "Enebrel", "Sam", DateTime.Now);

table.Rows.Add(10, "Hydralazine", "Christoff", DateTime.Now);

table.Rows.Add(21, "Combivent", "Janet", DateTime.Now);

table.Rows.Add(100, "Dilantin", "Melanie", DateTime.Now);

return table;

}

public class CustomGridDataRowBehavior : GridDataRowBehavior

{

protected override bool ProcessEnterKey(KeyEventArgs keys)

{

int currentIndex = (int)this.GridControl.CurrentRow.Cells[this.GridControl.CurrentColumn.Name].Tag;

foreach (var row in GridControl.Rows)

{

foreach (GridViewCellInfo cell in row.Cells)

{

if ((int)cell.Tag == currentIndex + 1)

{

this.GridControl.CurrentRow = row;

this.GridControl.CurrentColumn = cell.ColumnInfo;

break;

}

return true;

}

I hope this will be useful.

Hi Susan,

I have tested this and it appears to work on my side. I have attached my test project. Could you please check it and let me know what is different on your side?

I am looking forward to your reply.
