ColorBox color input and output

I have been looking at the ColorBox control, but I cannot figure out how to do simple things. What I want to do is specify the color displayed when the form containing the ColorBox control is opened, and extract the value of the new color chosen by the user.

I expected to be able to specify something like:

radColorBox1.InitialColor = Red;

and then get the new value if there is one.

Apparently one gets the new value from the ValueChanging or ValueChanged event handlers, which is straightforward enough I guess.

I program in C#. Any suggestions will be appreciated.

Excel Export - Convert to number message

Don't know if this has been mentioned before but I'll share my solution anyway.

The issue is when you use the ExportToML on a RadGridView and the resulting excel-file gives you the little green triangle on every cell. Where it says "the number in the cell is formatted as text or preceded by an apostrophe". The yellow mark gives you the option to "convert to number" before you can use the values as expected. Highly annoying if you ask me.

Solution

If you google this you get the standard solution of using ExcelCellFormatting event and change

the property of:

e.ExeclStyleElement.NumberFormat.FormatType
e.ExeclStyleElement.NumberFormat.FormatString.

This however doesn't solve the problem. The solution is not the visual style export, but in the data.

e.ExcelCellElement.Data.DataType = DataType.Number;
e.ExcelCellElement.Data.DataItem = old;

var exporter = new ExportToExcelML(grid) {SheetName = sheetname, ExportVisualSettings = true};

exporter.ExcelCellFormatting += exporter_ExcelCellFormatting;

exporter.RunExport(tempPath);

private static void exporter_ExcelCellFormatting(object sender, ExcelCellFormattingEventArgs e)

{

if (!e.GridCellInfo.ColumnInfo.Name.StartsWith("v.")) return;

if (e.GridCellInfo.Value == null) return;

e.ExcelStyleElement.NumberFormat.FormatType = DisplayFormatType.Custom;

e.ExcelStyleElement.NumberFormat.FormatString = "#";

int old;

if ( int.TryParse(e.GridCellInfo.Value.ToString().Replace(",",""), out old))

{

e.ExcelCellElement.Data.DataType = DataType.Number;

e.ExcelCellElement.Data.DataItem = old;

}

Hide/Remove PivotGrid Drag & Drop Headers

So far the only way I've been able to hide them is by setting the radPivotGrid.ColumnHeaderHeight = 0

Is there a cleaner way to hide/remove them?

RadSplitButton - Programatically Change Border Color

How do I change the border color on a radSplitButton? I'm using

btnUser.DropDownButtonElement.ButtonSeparator.BorderColor = Color.FromArgb(255, 190, 106)
btnUser.DropDownButtonElement.ActionButton.BorderElement.ForeColor = Color.FromArgb(255, 190, 106)

but it only changes part of the border color. The left and right borders are unchanged.

Buttons, RadioButton, CheckBox, etc

RadTreeNode .Text vs .Value

Why do these two properties seems to conflict. I want to store an object in .Value and display a simple String in .Text, but it seems I can't do this...

The last one set always overrides the other.

What Event Should Be Used to Expand an Item

I couldn't find a property to set that will always expand all property grid items, so now I'm trying to expand just one item when the property grid is loaded. I tried putting the Expand() call in the CreateItem event handler, but the item is always null. If I put the Expand() call in the ItemFormatting event handler, I am unable to collapse the item. Here is the code I'm using:

PropertyGridItem item = e.Item as PropertyGridItem;



if

(item.Label == "abc" && !item.Expanded)

{

item.Expand();

}
