how to put tooltip on the datagrid column header and also on cell of that column using vb.net 2003? plz help if anyone knows.here datagrid is bound at runtime.

Hi,
You can assign tooltop to header and cell of the datagrid at runtime using ItemDataBound event of datagrid.
void dg_ItemDataBound(object sender, DataGridItemEventArgs e)
{
if (e.Item.ItemType = ListItemType.Header)
{
e.Item.ToolTip = "tooltip";
e.Item.Cells[0].ToolTip = "toolTip";
}
}
Above code is in C# so apply vb syntax to implement.
I hope this will help you.
Thanks and Regards,

You will have to use Ajax if you want to use Javascript for this functionality of Datagrid.
Writing client side code for these kind of functinality is not always the best practice.

It is not a good practice.
Go with Ajax. that will be better for this.

Hi,
I am getting an error while uploading and deleting a file in the server. Using the following code.
ERROR MESSAGE: The process cannot access the file 'index_01.jpg' because it is being used by another process.
protected void Button4_Click(object sender, EventArgs e)
{
DirectoryInfo d = new DirectoryInfo(Server.MapPath("~\\Upload\\"));
if (FileUpload1.HasFile)
{
FileUpload1.SaveAs(@"D:\\Dotnet_Projects\\kyc_start\\Upload\\" + FileUpload1.FileName);
}
else
{
Label1.Text = "No File Uploaded.";
}
foreach (FileInfo f in d.GetFiles("*.jpg"))
{
byte[] buffer = new byte[f.OpenRead().Length];
f.OpenRead().Read(buffer, 0, (int)f.OpenRead().Length);
PhotoManager.AddPhoto(buffer);
f.Delete(); //ERROR HERE!!!
}
this.PhID();
}
Plz let me know where i am making mistakes. ITS working fine in local server.

My guess is that your site is still running or perhaps your app pool is still running. Normally when you delete files that belong to a web site you will need to stop the web site and the app pool to make sure that none of the files are cached in memory. So if you shut down the app pool that your web app is using I think you should be able to delete the file.
Hope that helps.

Hi Ben,
I would like to explain my task more clearly...
Task: Upload Client photos to server and display it. (registration form)
Strategy followed:
1. Upload images to \upload\ folder in server.
2. Read all images in \upload\ folder and put it in sql database.
3. delete the image from \upload\ folder.
4. display it in the webform.
All this tasks should perform in a single button click "upload image"
I succeeded In SETPS: 1, 2 and 4.
I could not delete the file (step 3) soon after I upload the file into the database.
IN this situation i could not stop the site for deletion I need some suggestions that can delete the file soon after Step 2.
Plz let me know your thoughts.
Regards,
JJ

I am not sure what code you are using to read the images, but I would guess there is a chance that code is not properly closing its connection to the image it just read. The only other thing I have seen with images is the need to call garbage collection. So after you read the images and close the connections to the image then you may need to call gc.Collect
Hope that helps.

Here is an example of openread with a fileinfo
using (FileStream fs = fi.OpenRead())
{
byte[] b = new byte[1024];
UTF8Encoding temp = new UTF8Encoding(true);
while (fs.Read(b,0,b.Length) > 0)
{
Console.WriteLine(temp.GetString(b));
}
}
When the using is used the openread is closed when you reach the end of the using. So you are not closing your openread.

Thank you for the info. I will check once again all my connections and stream readers used to read the images to DB.

}
A quick brainstorming query: Did you observe whether this FileInfo keeps an handle also?

I want to know how should we give validation for phone numbers.
my phone number format is 0000-000-000
|
|

There are a couple of easy ways
1. Client-side
There is a nice ASP.net AJAX control in the toolkit which offers this if you want to use it. Link - http://ajax.asp.net/ajaxtoolkit/MaskedEdit/MaskedEdit.aspx[^]
2. Regular expression validator
You could write a simple regular expression to match the input against and use a validator on the page. The regular expression would be something like
^d{4}-\d{3}-\d{3}$ (Not 100% sure of the exact syntax)
Try www.regexlib.com as a great source for help and examples of regular expressions.

Heared of Regular expression ?
|

Here is your code for Validation of Phone Number, with asp:regularexpressionvalidator
<%@ Page Language=VB Debug=true %>
<title>Validating a Phone Number with a RegularExpressionValidator Control
Please enter your phone number:
<asp:textbox
="" id="txtPhoneNumber" runat="server">
<asp:regularexpressionvalidator
="" id="regZipCode" controltovalidate="txtPhoneNumber" validationexpression="\\d{4}\-\d{3}\-\d{3}" display="Dynamic" font-name="Arial" font-size="11" runat="server
">
You must enter a phone number in the form of 9999-999-999.
<asp:button
="" id="butOK" text="OK" type="Submit" runat="server">

Satips.

like 0000-000-000 or 000-000-000
