We recently upgraded our WinForms controls from Q2 2011 to Q1 2013 and now have an issue when opening many of the windows forms. The Error is: Unable to cast object of type ‘Telerik.WinControls.UI.RadButton’ to type ‘Telerik.WinControls.RadControl’. Does anyone have any information on what could be causing this error? Thank you for your help.

Vertical Scrollbar in Monthview

I can't seem to get the vertical scrollbar to work in monthview. I can make it visible, but it doesn't want to scroll the scheduler. Autoscroll doesn't seem to do it.

Any ideas?

Printing header RTL

Hi,
is there a way to make the right header in the RadPrintDocument right aligned so if i have mixed language text (hebrew and english in my case) It will show it right...

currently i use this function (partly taken from this site - c-sharp-split-and-revers-sentence-with-two-languages):

public static string ProcessEnglishHebrewSentence(string sentence)

{

var ret = new List<string>();

string[] words = sentence.Split(' ');

var curHebrewList = new List<string>();

var curEnglishList = new List<string>();

bool curLangIsHebrew = false;

string w;

string reversed;

for (int i = words.Length; i > 0; i--)

{

w = words[i - 1];

if (System.Text.RegularExpressions.Regex.IsMatch(w, @"\p{IsHebrew}") && curLangIsHebrew) // we have a word in Hebrew and the last word was in Hebrew too

{

curHebrewList.Add(w);

}

else if (System.Text.RegularExpressions.Regex.IsMatch(w, @"\p{IsHebrew}") && !curLangIsHebrew) // we have a word in Hebrew and the last word was in English

{

if (curEnglishList.Any())

{

curEnglishList.Reverse();

ret.AddRange(curEnglishList);

} // reverse current list of English words and add to List

curEnglishList = new List<string>(); // create a new empty list for the next series of English words

curHebrewList.Add(w);

curLangIsHebrew = true; // set current language to Hebrew

}

else if (!System.Text.RegularExpressions.Regex.IsMatch(w, @"\p{IsHebrew}") && !curLangIsHebrew) // we have a word in English and the last word was in English

{

if (System.Text.RegularExpressions.Regex.IsMatch(w, @"[a-zA-Z]"))

{

reversed = new string(w.Reverse().ToArray());

reversed = reversed.Replace("(", "^");

reversed = reversed.Replace(")", "(");

reversed = reversed.Replace("^", ")");

}

else

reversed = w;

curEnglishList.Add(reversed); // reverse and add it to the current series of English words

}

else if (!System.Text.RegularExpressions.Regex.IsMatch(w, @"\p{IsHebrew}") && curLangIsHebrew) // we have a word in English and the last word was in Hebrew

{

if (curHebrewList.Any())

{

curHebrewList.Reverse();

ret.AddRange(curHebrewList); // add current list of Hebrew words to List of Lists

}

curHebrewList = new List<string>(); // create a new empty list for the next series of Hebrew words

if (System.Text.RegularExpressions.Regex.IsMatch(w, @"[a-zA-Z]"))

{

reversed = new string(w.Reverse().ToArray());

reversed = reversed.Replace("(", "^");

reversed = reversed.Replace(")", "(");

reversed = reversed.Replace("^", ")");

}

else

reversed = w;

curEnglishList.Add(reversed);

curLangIsHebrew = false; // set current language to English

}

else

{

throw new Exception("there should be no other case...");

}

if (curHebrewList.Any())

{

curHebrewList.Reverse();

ret.AddRange(curHebrewList);

}

if (curEnglishList.Any())

{

curEnglishList.Reverse();

ret.AddRange(curEnglishList);

}

return ret.Aggregate((a, b) => a + " " + b);

}

I would like to know if there is a more elegant sollution

RadTextBoxControl : Watermark enabled autocomplete

Helo !

I used RadTextBoxControl in winforms.(win7, .net4.0)
I used this control to search records (Text box to search records with autocomplete feature).

Now, i want my autocomplete to be similar as of google search box works.
like, the moment i started typing text in the textboxcontrol the first matching record should appear as watermark, instead of highlighted and selected.This autocomplete records being pulled from database.

While typing the text in radtextboxcontrol, the matching characters should be highlighted with bold fonts and the rest characters from matching records should be watermarked. Contents being displayed in dropdown should be inversely formatted with respect to contents in textbox(e.g. matching characters should be watermarked and rest should be bold)

For illustration of my problem you may have look on google searchtextbox.

Looking ahead for your response.

Thanks,
Arpus

Gridview Updates

First of all let me apologize for what is probably a easy to answer question. I am unsure of what I need to do for the next step in getting the update to fire and get posted to the SQL DB. This is about the last thing I need to do to have this app finished. I have all the other code needed done.

I have the radgridview1 already being filled by a dataset. How or rather what is the best way to get the updates posted to the db? I have done my app in C#. In this grid I am forcing the user to do a cell selection to make each change in the row.

Any help you could offer would be greatly appreciated.

Why RadDock does behave correctly?

Hi,

if LoadFromXml fails, I am loading it from the defaultsetting.xml created during design time or copied from the file saved by raddock.

SaveToXml() method itself.

The problem I am having is that toolwindow does not behave correctly. I can't close it or float around etc. 

Code snippet:

if (File.Exists(DockStatePath))
{
try { radDock.LoadFromXml(DockStatePath);
}
catch (XmlException)
{
radDock.LoadFromXml("defaulsetting.xml");
}
}

Thx in advance

Dock
