Hi,
With the following code I am getting error that
at this line
int.parse(viewstate["0"]) +=1;
error:-
Cannot implicitly convert type 'object' to 'string'. An explicit conversion exists (are you missing a cast?)
if(!ispostback)
{
viewstate["index"]="0";
}
On Next Button event
if (viewstate["index"].ToString()=="0")
{
//Get question from arraylist with 0 index
int.parse(viewstate["0"]) +=1;
}
else
{
//Get question from arraylist with viewstate index number
string quest=arrlist[int.parse(viewstate["index"])]
//check if question is from last array index then disable next button
if(int.parse(viewstate["index"])==arrlist.count){
//disable next button}else{int.parse(viewstate["0"]) +=1;}
}
On Previous Button event
if (viewstate["index"].ToString()=="0")
{
//Get question from arraylist with 0 index
//disable previous button
int.parse(viewstate["0"]) +=1;
}
else
{
//Get question from arraylist with viewstate index number
string quest=arrlist[int.parse(viewstate["index"])]
int.parse(viewstate["0"]) -=1;
}

HI Knowledge!
Actually I m not getting what exactly ur problem lies.
Is label inside the Grid or Outside?
do ur Source has the Unique Id that u r use to bind the grid?
And yes About the Error :
This Error Generally Arises when There is Unavailability of a Control.

This event doesn't give you any selected row,you have to select row of the gridview as
GridView3.SelectedIndex=e.NewSelectedIndex;
GridView3.datasource=place here datatable
GridView3.databind()
place ur code in the following event. I think your problem will be solved.
protected void GridView3_SelectedIndexChanged(object sender, EventArgs e)
{
string str = GridView3.SelectedRow.Cells[1].Text;
lblMsg.Text = str.ToString();
OR
lblMsg.Text = GridView3.SelectedRow.RowIndex.ToString();
}

Hello Genious...
I have developed folder browser which only displays the folders and not files in browser window..and let users selects folder path.
This user class like Win32SDK and inports dlls like shell32 and shared function
<dllimport("shell32.dll", preservesig:="True," charset:="CharSet.Auto)"> _
Public Shared Function SHBrowseForFolder(ByVal bi As BROWSEINFO) As IntPtr
End Function
and opens the browsing window with
idListPtr = Win32SDK.SHBrowseForFolder(bi).
Now one interesting thing is that this works in my application perfectly.. but when i publish this on local .. its not even open browser window and page opening gets hang...
i think it is may be because security of windows's dll problem..
Any solutions..? please...

Why do you want to display a folder browser dialog from a web application? What purpose does it serve?

Hi Paul..
First of all ,Thanks for replying...
Ok.. now i will tell you why it is needs...
I have requirement like User can be able to select folder path from folder browser.. and then after selecting that, some files will copy from to server to user's selected path(Selected folder)
Eg if user selects desktop then user's selected path is like
C:\Documents and Settings\Administrator\Desktop
and next, some files from my server will copies to users desktop.
Is there any other way to get selected folder path from user's local drive then i will always welcome your any sugestions...
Thanks..

You can't do this. The browser can't access local resources on the client machine for obvious security reasons. Otherwise, websites could do malicious things with your user's file system. You have to adopt a different mindset when working with web applications. Some of the things you take for granted in Windows applications simply are not possible.
The best thing you can do is to provide the facility to download a file or files. You could consider packaging a set of files up into a ZIP archive and then providing the user with the facility to download it.

Is your application in asp.net? if yes then why you are not using classes in system.io namespace to browse folders.

By default, when a file is deleted using the System.IO methods it won't be moved to the Recycle Bin. You have to write specific code to do that.

By default it goes to recycle bin . I need to know how to delete it completely without going into recycle bin.
|
|
|
|
|
I think u want something like Permanent delete?
Once u delete a file then it goes to recycle bin and then it also deleted from recycle bin also?

1st Can u manage to delete it to the disk level? Means it the deleted file goes to R.Bin?
If that is achieved then you have to make some registry level code, Cause it becomes the O.S related Operation. Try to search in Operating System Forum for this 2nd level delete problem.
But 1st u have to delete file from 1st level, i.e from drives.
Just try the below links for 2nd level deletion

Hiya,
It is quiet simple 
My.Computer.FileSystem.DeleteFile("MyFile.txt", FileIO.UIOption.OnlyErrorDialogs, FileIO.RecycleOption.DeletePermanently)
I write this line of code in VB but I'm sure that you will know where to put the funny little bracket things
Hope it was helpful!
