1. When I click the "next question" button the page_load runs again.
2. In the page_load the querysting checks the number of the question
3. the question is loaded from the databse
4. In the database there is a field for random on/off.
5. The checkedlistbox webcontrol object is created.
6. If random - random values are created and put into a list (in this case the list could look liek this: 2, 0, 1)
7. The name of the towns are added into the checkedlistbox as listitems, the order of the listitems is added like this:
for (int i = 0; i < this.LstChkBoxes.Count; i++)
{
myCheckBoxList.Items.Add(new ListItem(this.LstChkBoxes[lstRandom[i]].sText, this.LstChkBoxes[lstRandom[i]].nAlternatives.ToString()));
}
8. The webcontrol is then added into the panel on the webpage, but in a different order than before. In the radiobutton-case the selection is attached to the choice on the second rendering of the page, but not in the checkboxcase.
This is the code that creates the webcontrol CheckBoxList
public override WebControl ToWebControl()
{
myCheckBoxList = new CheckBoxList();
myCheckBoxList.BackColor = ColorTranslator.FromWin32((int)CrBkColor);
myCheckBoxList.Style.Add("Position", "Absolute");
myCheckBoxList.Style["Top"] = ITop.ToString() + "px";
myCheckBoxList.Style["Left"] = ILeft.ToString() + "px";
myCheckBoxList.Style.Add("z-index", this.Order.ToString());
myCheckBoxList.ID = this.checkboxId.ToString();
myCheckBoxList.AutoPostBack = true;
if (this.BRandomShow)
{
Random rand = new Random();
List<int> lstRandom = new List<int>();
while (nmbrsAdded == false)
{
int rnd1 = rand.Next(0, this.LstChkBoxes.Count);
if (!lstRandom.Contains(rnd1))
{
lstRandom.Add(rnd1);
if (lstRandom.Count == this.LstChkBoxes.Count)
nmbrsAdded = true;
}
}
for (int i = 0; i < this.LstChkBoxes.Count; i++)
{
myCheckBoxList.Items.Add(new ListItem(this.LstChkBoxes[lstRandom[i]].sText, this.LstChkBoxes[lstRandom[i]].nAlternatives.ToString()));
}
}
else
{
for (int i = 0; i < this.LstChkBoxes.Count; i++)
{
myCheckBoxList.Items.Add(new ListItem(this.LstChkBoxes[i].sText, this.LstChkBoxes[i].nAlternatives.ToString()));
}
}
if (this.bBorder)
{
myCheckBoxList.BorderStyle = BorderStyle.Solid;
myCheckBoxList.BorderColor = Color.Black;
myCheckBoxList.BorderWidth = Unit.Pixel(2);
}
if ((Lwfont.LocalFontStyle & 1) != 0)
myCheckBoxList.Font.Bold = true;
if ((Lwfont.LocalFontStyle & 2) != 0)
myCheckBoxList.Font.Italic = true;
if ((Lwfont.LocalFontStyle & 4) != 0)
myCheckBoxList.Font.Underline = true;
if ((Lwfont.LocalFontStyle & 8) != 0)
myCheckBoxList.Font.Strikeout = true;
if (this.lwfont.LocalFontName != null)
{
myCheckBoxList.Font.Name = this.Lwfont.LocalFontName.ToString();
myCheckBoxList.Font.Size = lwfont.LocalFontSize;
myCheckBoxList.ForeColor = ColorTranslator.FromWin32((int)Lwfont.LocalFontColor);
}
else
{
Test test = new Test();
test = HttpContext.Current.Session["test"] as Test;
myCheckBoxList.Font.Name = test.SfontName;
myCheckBoxList.ForeColor = ColorTranslator.FromWin32((int)test.IfontColor);
}
int height = this.IBottom - this.ITop;
int width = this.IRight - this.ILeft;
myCheckBoxList.Width = width;
myCheckBoxList.Height = height;
return myCheckBoxList;
}

hi,
sory for the late reply,
what happens if you set the selected values again, in the for loop where u r adding them?
<pre>
if (this.LstChkBoxes.Items[i].Selected == true)
{
myCheckBoxList.Items.FindByValue(this.LstChkBoxes[i].nAlternatives.ToString()).Selected = true;
}
</pre>

I don't know how to do that in an easy way. I will simply try another solution and abandon this one...
Thanks anyway

Are you randomising the text of the Checkboxes or the actual Checkbox objects?
|
|
|
|

or you can give me any website demo using asp.net..

Hi,
I m currently developing a project on Xml Editor in vb.net...While trying to validate the xml against dtd i m getting the following error :
XmlValidatingReader is obsolete.
I tried using XmlReaderSettings but its showing an error saying that "The XmlSchemaSet on the document is either null or has no schemas in it. Provide schema information before calling Validate."
This is the coding i ve written :
Dim xmlV As New XmlDocument
Dim xmlP As New XmlTextReader(TempFile)
Dim settings As New XmlReaderSettings
Dim eventhandler As ValidationEventHandler
eventhandler = New ValidationEventHandler(AddressOf WriteErrorLog)
xmlV.Validate(eventhandler)
settings.ValidationType = ValidationType.DTD
settings.ProhibitDtd = False
Dim reader As XmlReader
reader = XmlReader.Create(xmlP, settings)
xmlV.Load(reader)
ErrStr = ""
ListBox1.Items.Clear()
IsValid = True
Do
Try
If reader.Read() Then
lineInf = CType(xmlV, IXmlLineInfo)
End If
Catch exx As Exception
Try
IsValid = False
If lineInf.HasLineInfo Then
ErrStr = lineInf.LineNumber.ToString + ": " + lineInf.LinePosition.ToString + " " + exx.Message
End If
If exx.Message.IndexOf("EndElement") > 1 Then
Exit Do
End If
ListBox1.Items.Add(ErrStr)
Catch eeex As Exception
MsgBox("Some unexpected error occurred " + vbNewLine + eeex.Message, MsgBoxStyle.Information, "Error")
Exit Do
End Try
End Try
Loop While Not xmlP.EOF
reader.Close()
xmlP.Close()
Me.Cursor = System.Windows.Forms.Cursors.Default
If IsValid = False Then
MsgBox("File is not valid", MsgBoxStyle.Exclamation, "Error")
Else
MsgBox("File is valid", MsgBoxStyle.Information, "OK")
End If
End Sub

How can I reduce exactly 6 months from a specific date?
|
|
|
|
|
Assuming that you don't need to bother about Time zones, Day light savings etc., you can use the AddMonths method of the DateTime instance.
You just need to pass negative value to subtract and positive value to add.
MSDN listing for AddMonths method[^]
HTH!
|
|
|
|
|
|
I dont know is this posible in asp.net but you try this with Sql
'Select DateAdd(month,-6,'03/06/2010')'
Output :'2009-09-06 00:00:00.000' 
|
|
|
|
|
DateTime specificdate= DateTime.Now;
specificdate.AddMonths(-6);

I have a series of functions for manipulating strings, doing route distance calculations......
In ASP I wuold have placed them in an include file, linked the file and that was it.
Can anyone help me do the same in ASP.net? Where do I store them and how do I attach them so I can call them, idealy as a strongly typed item?
Many thanks
John

| Why not put all of your methods in a class library. If all they do is take in a string, change it, and spit it back out you can make the methods static and you don't have to instantiate any classes to use them. Don't blame me. I voted for Chuck Norris.
|
|
|
|
|
Yes, You can put the in a class Library and add the dll as reference in your project, or you can use as StringUtility Class in App_Code Folder.
|
|
|
|
|
|
Thanks
Looks like a dll is the answer.
Will have to look at how to manually make them (batch file...) as do not have full Visual Studio, just web express.

Hi,
I have a compare validator which compares the email and confirm email text boxes on my page.
Is there anyway that I could trim the spaces at the start and end of these email address and then get them compared by the control?
As is expected, It gives error if there is space at the end of either text boxes.
Thanks
