Hi, how can I set the default value for Draw Shape and Draw Text element. For example I set the default value border thickness=3 , shape color = red, shape fill = transparent.

Is There A Way to Put Something to Replace a Footer?

The documentation makes no mention of a footer in a virtual grid. Is it possible to put lets's say a label or some other control under the grid - to give a record count after filtering, for example.

How to show the portion of dataset which generated values in a cell

Hi, excel have a very nice feature that, when on a pivot, if you double click a cell, it shows the full dataset which is bound to the same cell.

It is possible to achieve the same by using the radpivotgrid?

For example we need to know, when a user double clicks on a cell which is the result of an aggregate (sum, average etc..) what are the rows on the dataset which generated that sum.

Trackbar Range Value Update

I am struggling with an feature that I'd like to implement.

Basically, I'd like a visual cue that indicates the current value of the range as end user changes the value of the range.

My TrackBar has 1440 minutes and I'd like to display what minute they're on without it being guess work.

I attached a screenshot of my implementation of the track bar.

Ideally, I'd like to display a label underneath the TrackbarThumbElement that would update as the value updates and then disappear. Any ideas how I might be able to update the UI with the current value of the range as the end user is manipulating the control?

Show displaymember value instead of valuemember value

Hi guys,

I have a customized grid where i change the type of the editorElement in one cell based on the value on another cell.
One of this editors are the RadDropDownListEditorElement. The displaymembers shows nicly when dropped down.
But when i choose one of the elements in the dropdown list, the dropdown closes and the valuemember is presented in the cell.

I need the valuemember in some operations after this, but i want the cell to show the displaymember.

Here is the code in the CellEditorInitialized:

void TextCodeGridView_CellEditorInitialized(object sender, Telerik.WinControls.UI.GridViewCellEventArgs e)

{

var editManager = sender as GridViewEditManager;

var editor = editManager.ActiveEditor as RadDropDownListEditor;

if (editor == null) return;

var editorElement = ((RadDropDownListEditor)editor).EditorElement;

switch (e.ColumnIndex)

{

case 0:

var tcArray = _db.TCs.Where(t=>t.TC_GROUP_MEMBERs.Any(tcg=>tcg.TC_GROUP.LAND_IDX == Startup.CurrentConsultant.CountryId)).ToList();

tcArray.Insert(0, null);

((RadDropDownListEditorElement)editorElement).DataSource = tcArray;

((RadDropDownListEditorElement)editorElement).DisplayMember = "TC1";

((RadDropDownListEditorElement)editorElement).ValueMember = "TC1"; ;

if (this.TextCodeGridView.CurrentRow.Cells[0].Value == null)

((RadDropDownListEditorElement)editorElement).SelectedIndex = 0;

else

((RadDropDownListEditorElement)editorElement).SelectedIndex = tcArray.IndexOf(_db.TCs.SingleOrDefault(t => t != null && t.TC1 == this.TextCodeGridView.CurrentRow.Cells[0].Value));

break;

case 1:

var tclistArray = _db.TC_LISTs.Where(t => t != null && t.TC == this.TextCodeGridView.CurrentRow.Cells[0].Value).ToList();

tclistArray.Insert(0, null);

((RadDropDownListEditorElement)editorElement).DataSource = tclistArray;

((RadDropDownListEditorElement)editorElement).DisplayMember = "TEXT";

((RadDropDownListEditorElement)editorElement).ValueMember = "VALUE"; ;

((RadDropDownListEditorElement)editorElement).SelectedIndex = tclistArray.IndexOf(tclistArray.SingleOrDefault(t => t != null && t.ISDEFAULT));

this.TextCodeGridView.CurrentRow.Cells[1].Value = tclistArray.SingleOrDefault(t => t != null && t.ISDEFAULT).TEXT;

break;

}

Custom Items cause infinity loop

Hello all,

i am trying to follow the official tutorial considering custom items for the RadPropertyGrid (https://docs.telerik.com/devtools/winforms/controls/propertygrid/custom-items) in a Progress Openedge 11.7 environment. I set up a test project consisting of a Form that holds a RadPropertyGrid and a Button whose Click Event will set the SelectedObject of the RadPropertyGrid. All other classes are more or less exactly translated into OpenEdge code from the tutorial.

The problem appears to be the assignment of the "ItemElementType" in the custom CreateItemElement

On the line "e:ItemElementType = TypeHelper:GetType("CustomItemElement")." the client begins to fire the event again and cause an infinit loop of event calls.

I could provide the sample project as .7zip if you like.

Rename the selected tab title

Hi

This code correctly changes the name of the tab after a myUserControl is added.
How can I change the title of the selected tab anywhere in the program without calling RadTabbedFormControlEventArgs e?

code snippet:

private void radTabbedFormControl1_TabAdded(object sender, RadTabbedFormControlEventArgs e)

{

UserControl1 myUserControl = new UserControl1();

myUserControl.Dock = DockStyle.Fill;

e.Tab.Controls.Add(myUserControl);

e.Tab.Owner.SelectedTab = e.Tab;

e.Tab.Text = myUserControl.this_title;

}
