Drag&Drop cannot work under the column sorting

Hello,

My gridview is in bound mode. I reorder the rows by drag & drop. I'm inspired by this telerik github demo:

https://github.com/telerik/winforms-sdk/tree/master/GridView/BoundGridReorderRows/GridViewRowsReorderBoundModeVB

I change the order of data source in order to reorder the rows by drag & drop. It worked well.

But if a column is sorted, any drag & drop cannot be toke into account. And then if I canceled a column sorting, the order synchronize well by drag & drop.

I wonder the column sorting maybe changed the order of child rows, not the order of rows, but then I change the order of rows (data source) by drag & drop, the order of child rows stays put strangely. So that's why there is no reordering affecting the display.

What happens between child rows and rows when I cancel the column sorting ?

What is the way out of this situation? I would like drag & drop has higher priority than column sorting/grouping.

Thank you by advance.

RadTreeView ContextMenu for certain nodes only

Hello,

I am wondering if it is possible to set a RadContextMenu for certain nodes when creating them programmatically.

For example, my tree will look something like this:

[MAIN NODE]

[Child1]

[Child2]

[MAIN NODE 2]

[Child1]

[Child2]

Would it be possible to have a RadContextMenu only for the parent node, and then a separate RadContextMenu for all the Child nodes?

Cannot select the entire row

Dear all,

After setting the selectionmode attribute to CellSelect in RadGridView, look at the photos below.

Click on the area in the red circle and the back cell row becomes highlighted in orange. However, the inner part of the circle does not change color.

This is not a whole row selection, I need a whole row selection

Is that possible?

What should I do?

Best wishes

Autocomplete gridViewComboBoxColumn: Suggestion getting appended to input incorrectly

I have a GridViewComboBoxColumn whose autocomplete behavior is undesired upon first cell click. Users are entering in a value, but when they first try to do something their input isn't properly appending to what they type and instead appends the first suggestion entirely onto their input. Please see UndesiredBehavior.gif.

Strangely enough, if they delete everything in the cell or change it and go back to it later on, then the behavior is desired: suggestions are being appended properly to what their input is. Please see DesiredBehavior.gif.

I am having a work around right now by instructing users to CTRL + A upon first entering into the cell and then deleting whatever is appended to their first key stroke, and then typing again, but I get complaints from users that they shouldn't have to do this.

Here is my code. Any suggestions?

         private void radGridViewDetail_CellEditorInitialized(object sender, GridViewCellEventArgs e)

        {



            if (e.ActiveEditor is RadDropDownListEditor)

            {

                //RadDropDownListEditor editor = (RadDropDownListEditor)e.ActiveEditor;

                RadDropDownListEditor editor = this.radGridViewDetail.ActiveEditor as RadDropDownListEditor;

                if (editor != null)

                {

                    RadDropDownListEditorElement element = (RadDropDownListEditorElement)editor.EditorElement;

                    element.AutoCompleteSuggest.DropDownList.SelectAllText();

                    element.AutoCompleteSuggest.DropDownList.DropDownSizingMode = SizingMode.UpDownAndRightBottom; // This does not work

                    element.ArrowButton.Visibility = Telerik.WinControls.ElementVisibility.Collapsed; // This works

                    element.AutoCompleteMode = AutoCompleteMode.SuggestAppend;

                    element.AutoCompleteSuggest.DropDownList.DropDownMinSize = new Size(275, 100);

                    element.AutoCompleteSuggest.DropDownList.MaxLength = 30;    

                switch (radGridViewDetail.CurrentColumn.Name)

                    {

                        case "CO":

                            element.AutoCompleteSuggest.DropDownList.DropDownMinSize = new Size(100, 100);

                            element.AutoCompleteDataSource = companyCodeTable;

                            element.AutoCompleteDisplayMember = "COMP_CODE";

                            element.AutoCompleteValueMember = "COMP_CODE";

                            element.DropDownWidth = 200;

                            break;

                        case "CC":

                            int minimumWidth = int.Parse(costCenterTable.Rows[0]["MAX_LEN"].ToString()) * 8;

                            element.AutoCompleteSuggest.DropDownList.DropDownMinSize = new Size(minimumWidth, 100);

                            element.AutoCompleteDataSource = costCenterTable;

                            element.DisplayMember = "ADDRESS";

                            element.ValueMember = "COST_CENTER";

                            element.AutoCompleteDisplayMember = "ADDRESS";

                            element.AutoCompleteValueMember = "COST_CENTER";

                            break;

                        case "Acct":

                            element.AutoCompleteSuggest.DropDownList.DropDownMinSize = new Size(275, 100);

                            element.AutoCompleteDataSource = glMajorTable;

                            element.DisplayMember = "ACCT_DESC";

                            element.ValueMember = "GLMAJOR";

                            element.AutoCompleteDisplayMember = "ACCT_DESC";

                            element.AutoCompleteValueMember = "GLMAJOR";

                            break;

                    }

                }

            }

        }

Highlight color of selected shape

When the user clicks on my shape, I'd like to make the outline red, and maybe thicker border. How can I accomplish this?

I thought it would just be a matter of putting this in my ElementShape-derived classes, but it seems my overrides for ForeColor and BackColor are only called when a new shape is placed on the diagram.

Thanks

Alternating rows color of the RadGridView without using RowFormatting events

Dear All,

I wanted to alternate the rows in my RadGridView, but the way I searched was using RowFormatting events, which I didn't want to use.

Is that possible?

Best wishes.

Lost range location after the form size changed

Hello,

I use range seletor to associate with a radchartview.

If I associate the RadChartView control to RadRangeSelector both in design time and in program (in the function "form_load"), there is a strange behavior.

After I changed the form size, the range selector will initialize start range and end range by which means it cannot memorize the start/end range set by the movement.

However, if I only do "Me.radRangeSelector1.AssociatedControl" ONCE in the design time or in the program, the problem will be disappeared.

In my opinion, there is a bug in RadRangeSelector. It cannot support AssociatedControl 2 times. This issue doesn't appear for the other proprieties, even I set the other proprieties both in design time and in program.

I made a simple demo, please download here:

https://www.dropbox.com/s/u61lk7yql1ua25f/TestRangeSelector.rar?dl=0

In order to reproduce the issue:

step 1. launch the demo

step 2. move range selector

step 3. change the form size

You will see the range selector return to its original location.

You can remove this line in RadForm1_Load:

RadRangeSelector1.AssociatedControl = RadChartView1

Or remove the associated control in design time. You will find range selector can memorize the location all the time.

It makes us lot of time to find out. If it is a bug, please correct it. If it is not, any explication ?

Thank you by advance.

Regards,

RangeSelector
