How to set focus to first column in add line

[Ruth Goldberg]

When on an add line, how can I set the focus to the first column? The column that gets the focus is wherever the user clicks on the line. I tried to set the focus in CurrentRowChanged event with this line:

 

    CType(e.CurrentRow, GridViewNewRowInfo).Cells("Acct_Code").CellElement.Focus()

 

 

but it has no effect. I looked into some of the other events, RowChanging and DefaultValuesNeeded, but CellElement is nothing at that point.

Hi Ruth Goldberg,

I am not sure that I completely understand your question. You can change the current column by settingGridViewColumn.IsCurrent property. For example:

Me.radGridView1.Columns("Acct_Code").IsCurrent = True

Then you can start editing a cell by calling RadGridView.BeginEdit method. If this doesn't help, please describe in more detail the exact behavior that you want to achieve. I will be glad to help further.

When I set the cell as current and begin edit as I show in the following code, the field is highlighted and ready to edit, but the cursor is not inside the cell. You have to click in it to get the focus there. What else can I do so the user doesn't have to click but can just start typing?

            CType(e.CurrentRow, GridViewNewRowInfo).Cells("Acct_Code").CellElement.Enabled = True
            Me.TblAccountRadGridView.Columns("Acct_Code").IsCurrent = True
            Me.TblAccountRadGridView.BeginEdit()

Hello Ruth Goldberg,

Thank you for writing back. This code should do the work, however it should be called when RadGridView is visible. You can call it in OnShown method of your form. Consider the code snippet below:

protected override void OnShown(EventArgs e)
{
    base.OnShown(e);
    this.radGridView1.BeginEdit();
}

Please send me your project if this doesn't help. I will try to find a working solution.

I don't understand your answer. The Shown event (I'm writing in vb not C#, as you can see) is called for the form. I want to start the edit and have the cursor in the first column when I click in the Add line, not when I open the form. Please explain what your code is supposed to accomplish. It would be more helpful if you used vb instead of C#.

Hello Ruth Goldberg,

Thank you for this clarification. If I understand your question correctly, you want to make the first column current and editable when clicking on "add new row". Here is the code in VB:

Me.RadGridView1.GridBehavior = New MyGridBehavior()

Public Class MyGridBehavior
    Inherits BaseGridBehavior

    Public Overrides Function OnMouseDown(ByVal e As System.Windows.Forms.MouseEventArgs) As Boolean
        Dim element As GridRowElement = TryCast(GridControl.ElementTree.GetElementAtPoint(e.Location), GridRowElement)
        If element IsNot Nothing Then
        GridControl.Columns(0).IsCurrent = True
        GridControl.MasterGridViewInfo.TableAddNewRow.IsCurrent = True
        GridControl.BeginEdit()
        Return True
        End If
        Return MyBase.OnMouseDown(e)
    End Function
End Class

I hope this helps.

Kind regards,

This does not work when another row is currently being edited.  Steps:

1. Click to edit a cell in another row, such that it shows a textbox for editing.

2. Click the Add New row.

What happens is that the same column that was being edited is the column that will start the New Row edits, not the first column.  Setting IsCurrent appears to be getting ignored.

Hello Andy,

Thank you for writing.

The code snippet my colleague has posted will no longer compile as the grid does not have a MasterGridViewInfo property. I am posting an updated version below: 

public partial class RadForm1 : Telerik.WinControls.UI.RadForm
{
    public RadForm1()
    {
        InitializeComponent();

        this.radGridView1.GridBehavior = new MyGridBehavior();
        this.radGridView1.DataSource = this.GetData();
        this.radGridView1.AutoSizeColumnsMode = Telerik.WinControls.UI.GridViewAutoSizeColumnsMode.Fill;
    }

    private DataTable GetData()
    {
        DataTable dt = new DataTable();
        dt.Columns.Add("Id", typeof(int));
        dt.Columns.Add("Name", typeof(string));
        dt.Columns.Add("Date", typeof(DateTime));
        dt.Columns.Add("Bool", typeof(bool));
        for (int i = 0; i < 10; i++)
        {
            dt.Rows.Add(i, "Name " + i, DateTime.Now.AddDays(i), i % 2 == 0);
        }

        return dt;
    }
}

public class MyGridBehavior : BaseGridBehavior
{
    public override bool OnMouseDown(System.Windows.Forms.MouseEventArgs e)
    {
        GridRowElement element = this.GridControl.ElementTree.GetElementAtPoint(e.Location) as GridRowElement;
        if (element != null)
        {
            this.GridControl.Columns[0].IsCurrent = true;
            this.GridControl.MasterView.TableAddNewRow.IsCurrent = true;
            this.GridControl.BeginEdit();
            return true;
        }

        return base.OnMouseDown(e);
    }
}

Please also check the attached short video showing the result on my end. With the provided solution the grid begins edit in the first column no matter if another is being edited at the moment or not.

In case your scenario is different or the solution is not working as expected on your end, please provide me with more details about your scenario so that I can investigate it. A sample code snippet could also help. In case you want to send us your project you can do it using the ticketing system.

I hope this helps. Let me know if you need further assistance.

Found it.  Has to do with the first column in my grid not being visible (because it was the "Id" column), so that when the GridBehavior attempts to make it current, the grid ignores the IsCurrent setting entirely, so that the current column isn't changed.

Better code for MyGridBehavior:

public class MyGridBehavior : BaseGridBehavior
    {
        public override bool OnMouseDown(System.Windows.Forms.MouseEventArgs e)
        {
            GridRowElement element = this.GridControl.ElementTree.GetElementAtPoint(e.Location) as GridRowElement;
            if (element != null)
            {
                for (int i = 0; i < this.GridControl.Columns.Count; i++)
                {
                    if (this.GridControl.Columns[i].IsVisible)
                    {
                        this.GridControl.Columns[i].IsCurrent = true;
                        break;
                    }
                }

                this.GridControl.MasterView.TableAddNewRow.IsCurrent = true;
                this.GridControl.BeginEdit();
                return true;
            }

            return base.OnMouseDown(e);
        }
    }

Hello Andy,

Thank you for the update.

Indeed the code snippet you shared seems valid and as long as it handles your actual scenario you can go ahead with it.

Let me know if you have other questions.
