Currently, similar conversions should be manually implemented by the users.
Sample method that could be used:
public static Color HexStringToColor(string hexColor)
{
// Remove the # at the front.
if (hexColor.StartsWith("#"))
{
hexColor = hexColor.Substring(1, hexColor.Length - 1);
}
byte a = 255;
byte r = 255;
byte g = 255;
byte b = 255;
int start = 0;
// Handle ARGB strings (8 characters long).
if (hexColor.Length == 8)
{
start = 2;
}
//Handle contracted RGB strings (3 characters long)
if (hexColor.Length == 3)
{
hexColor = string.Format("{0}{0}{1}{1}{2}{2}", hexColor[0], hexColor[1], hexColor[2]);
}
else if (hexColor.Length < 6)
{
hexColor = hexColor.PadLeft(6, '0');
}
// Convert RGB characters to bytes.
r = byte.Parse(hexColor.Substring(start, 2), NumberStyles.HexNumber);
g = byte.Parse(hexColor.Substring(start + 2, 2), NumberStyles.HexNumber);
b = byte.Parse(hexColor.Substring(start + 4, 2), NumberStyles.HexNumber);
return Color.FromArgb(a, r, g, b);
}

Hello,
we would like to have the capability to create a chart in excel export using Telerik.Documents.Spreadsheet

When a csv is exported the entire range which has values is exported. When export is done in Excel, the cells of this range which are empty are marked by an additional field, separated by a comma. This comma is present in SpreadProcessing only in places where it is obligatory for example in the middle of the row. Obligatory comma in this context means that without it the file will not be read correctly by Excel or SpreadProcessing. In places where it is not obligatory, like in an empty row or in the end of the row, it is skipped. These non-obligatory commas do not influence how the file will be interpreted by Excel, however, according to the most-popular csv spec, they should be present, which means that there could be parsers which are unable to parse the resulting file. (2.4 Each line should contain the same number of fields throughout the file.) Example: Exported by Excel: --------------------------------------- Product,Unit Price,Units in Stock,Discontinued Chai,$18.00 ,39, Chang,,17, Chef Anton's Cajun Seasoning,$22.00 ,53,No ,,, Chef Anton's Gumbo Mix,$21.35 ,0,No --------------------------------------- Exported by SpreadProcessing: --------------------------------------- Product,Unit Price,Units in Stock,Discontinued Chai,$18.00 ,39 Chang,,17 Chef Anton's Cajun Seasoning,$22.00 ,53,No Chef Anton's Gumbo Mix,$21.35 ,0,No --------------------------------------- Note the extra commas in the empty row and in the end of the first two rows in the SpreadProcessing sample.
The MATCH function searches for a specified item in a range of cells and returns the relative position of the item found in this range. A list of the supported functions is available at http://docs.telerik.com/devtools/document-processing/libraries/radspreadprocessing/features/formulas/functions This function can be implemented as a custom function. Check the following resources for more details on how to achieve that: - http://docs.telerik.com/devtools/document-processing/libraries/radspreadprocessing/features/formulas/custom-functions - https://github.com/telerik/xaml-sdk/tree/master/Spreadsheet/CustomFunctions Available in R3 2017 Official Release Version
Add support for CHOOSE function. CHOOSE uses the number parameter to return a value from the list of value arguments. A list of the supported functions is available at http://docs.telerik.com/devtools/document-processing/libraries/radspreadprocessing/features/formulas/functions This function can be implemented as a custom function.

Add support for TRIM function. TRIM removes all spaces from text except for single spaces between words. A list of the supported functions is available at http://docs.telerik.com/devtools/document-processing/libraries/radspreadprocessing/features/formulas/functions This function can be implemented as a custom function.

Add support for preserving and exporting the macros in a macro-enabled workbook. Macros are pieces of code written in Visual Basic for Applications (VBA) which are used to automate repetitive tasks in excel. The macros are part of the excel file. When a file contains a macro its extension becomes xlsm. SpreadProcessing should be able to import and export xlsm files and edit the macros in them.
This will enable printing with the following printing options: - Fit Sheet on One Page - Fit All Columns on One Page - Fit All Rows on One Page - Custom automatic scaling A possible implementation of a similar behavior is to use the PageSize property of WorksheetPageSetup and subtract the corresponding margin values (from the Margins property) from the width to calculate how many columns are fitting in some particular page size with 100% scale factor. Available in R2 2018 Official Release version.
