Hi
I have a RadDock control with a number of ToolWindows on it. The ToolWindows have CloseAction set to Hide. The user can "open" or "close" a toolwindow from a state button (and also a checked menu item). The state of the button (and the check on the menu) should indicate the whether or not the ToolWindow is displayed. Is there a way to tell if a ToolWindow is hidden programmatically?

Thanks

1. I like to submit a "bug report" that the Enter Key is not toggling expansion / collapse of the ChildGridViewTemplates of the CurrentRow unless they were previously expanded since the RadGridView has been opened.  In cases where it's not toggling, it's passed to RadGridView's KeyDown Event.  In cases where it is, it's passed to BaseGridBehavior's undocumented, Override-able ProcessKey Function.

2. I like to submit a "feature request" that an option be added to turn on / off the ChildView expansion / collapse behavior of the Enter Key.  When "on", it would always toggle expansion / collapse regardless of whether a Row was previously expanded.  When "off", it would do nothing except be passed to RadGridView's KeyDown Event.  a. The use of the Left and Right keys to expand / collapse a hierarchical / tree-like list are much more universal (see Windows Explorer, Outlook, VS, SSMS) where as the only place I could find the Enter Key key being used that way is the the Solution / Property Explorers in MS' VS and SSMS (not exactly common software for end-users) (1).  b. the Enter Key is commonly used for other purposes (i.e. selecting / opening an item) even in hierarchical / tree-style lists.  c. To override the Enter Key, I have to use the more difficult / non-intuitive method of overriding the GridBehavior Property vs. KeyDown Event.

Hello,

Hi,

MDI Parent, with maximised MDI child.

The control box sits marginally low (see shot_01.jpg).

In our database tables we have a field isDeleted. This indicates if a record is logically deleted. 

There is a Delete-Button on the form. If the user presses this button, the flag should be set, then the data saved. After that the window is closed and the user gets back to the form with the list. The list is built upon a database view with the where-clause "where IsDeleted = 0".

For editing the data I have a detail data form with a ObjectView. On the form there is a RadCheckbox-Control named cbIsDeleted.
The control is bound via the IsChecked-Property to the persistent data.

• If I check/uncheck the CheckBox with the mouse and save the data, the changed value is saved in the database.
• If I want to do the same programmatically, on the GUI the Checkbox will be checked/ unchecked. But when I want to save the data - the changed value for the Checkbox wouldn't be stored in the database: 

 

 

 

I tried also:

 

What's wrong? Should I set some other properties?

Thanks in advance
Bernhard

Good Evening All

I'd like to make a "feature request" to add an option to make the Tab appear even when there's only one ChildGridViewTemplate (i.e. only 1 sibling) on a given level.  This would help clarify what the ChildGridViewTemplate is for.

Hi,
     There are two columns in a grid placed in a windows form. The first column is a GridViewComboBoxColumn and the second one is a GridViewDataColumn. I have populated the combo box with values. I need to assign the selected value from the drop down to the cell on which it resides. The code i have written is given below.

private void BindData()
        {
            radGridView1.GridElement.BeginUpdate();
            var gridViewLookUpColumn = ((GridViewLookUpColumn)(radGridView1.CurrentRow.Cells["column1"].ColumnInfo));

            if (gridViewLookUpColumn == null) return;

            gridViewLookUpColumn.DataSource = FillData();
            gridViewLookUpColumn.DisplayMember = "Name";
            gridViewLookUpColumn.ValueMember = "Id";
            gridViewLookUpColumn.DropDownStyle = RadDropDownStyle.DropDownList;

            radGridView1.GridElement.EndUpdate();
        }

        private static DataTable FillData()
        {
            var dt = new DataTable();
            dt.Columns.Add(new DataColumn("Name", typeof(String)));
            dt.Columns.Add(new DataColumn("Id", typeof(Int32)));

            var dr = dt.NewRow();
            dr["Name"] = "Test 1";
            dr["Id"] = 1;
            dt.Rows.Add(dr);

            dr = dt.NewRow();
            dr["Name"] = "Test 2";
            dr["Id"] = "2";
            dt.Rows.Add(dr);
            return dt;
        }

 private void radGridView1_CellBeginEdit(object sender, GridViewCellCancelEventArgs e)
        {
            BindData();
        }

        private void radGridView1_CellEndEdit(object sender, GridViewCellEventArgs e)
        {
            try
            {
                var radEditor = radGridView1.ActiveEditor;

                if (radEditor == null) return;
                switch (radEditor.GetType().Name)
                {
                    case "RadComboBoxEditor":
                        {

                            var element = ((RadComboBoxElement)((RadComboBoxEditor)radGridView1.ActiveEditor).EditorElement);
                           
                            if (element == null) return;
                            var selectedText = ((RadComboBoxItem) element.SelectedItem).Text;
                            MessageBox.Show("Begin" + selectedText);

                            radGridView1.CurrentRow.Cells["column1"].CellElement.Text = selectedText;
                            //radGridView1.Rows[e.RowIndex + 1].Cells[e.ColumnIndex + 1].Value = element.SelectedValue;                                
                            break;
                        }
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

I can select the value from the dropdown. But the value assigned to the cell is not displaying. Please help me.
