How are you adding the row after deletion? Since you are getting IndexOutOfRange exception, you should check all the indexes you are using while adding the row.

I am clicking on the first cell in the next available row when I receive the error. When I selected the datatable to use for the grid it created a binding source. When I try to execute the RemoveAt with the binding source it errors out.

Is there an easier way to do this?

I have never used a wizard for doing something like this. I had set the datasource through code and deleted the row using same code as yours. I added and new row as well and didn't received any error.

protected void btnAdd_Click(object sender, EventArgs e)
{
Response.Cookies[txtCookieValue.Text].Value = txtCookieValue.Text;
DropDownList1.DataSource = Request.Cookies;
DropDownList1.DataBind();

}
protected void Button1_Click(object sender, EventArgs e)
{
Response.Cookies.Clear();
Request.Cookies.Clear();
DropDownList1.DataBind();
}

for (int i = 0; i < Response.Cookies.Count; i++)
Response.Cookies[i].Expires = DateTime.Now.AddDays(-1);
for (int i = 0; i < Request.Cookies.Count; i++)
Request.Cookies[i].Expires = DateTime.Now.AddDays(-1);

this is also not working

string[] c = Request.Cookies.AllKeys;
foreach (string co in c)
{
Response.Cookies[co].Expires = DateTime.Now.AddDays(-1);
}
this is working..

any idea why this approach is right and above 2 are wrong?

DataGridViewDataErrorContexts problem

Can anybody explain to me how I handle the DataError Event? I have the
following code but the error does not get picked up by any of them. Looking
at e.Context shows " Parsing | Commit | CurrentCellChange ", how do I get
the individual values?

if (e.Context == DataGridViewDataErrorContexts.Commit)
{
MessageBox.Show("Commit error");
}

if (e.Context == DataGridViewDataErrorContexts.CurrentCellChange)
{
MessageBox.Show("Cell change");
}

if (e.Context == DataGridViewDataErrorContexts.Parsing)
{
MessageBox.Show("parsing error");
}

if (e.Context == DataGridViewDataErrorContexts.LeaveControl)
{
MessageBox.Show("leave control error");
}

Hi,

DataGridViewDataErrorContexts is an enum and has the FlagsAttribute, which means all members are really bit-oriented flags, so try this:

if ((e.Context & DataGridViewDataErrorContexts.Parsing)!=0) {
    MessageBox.Show("parsing error");
}

PS: please use PRE tags to show code, as I did (see the difference?)

Smile | :)

I only read code that is properly formatted, adding PRE tags is the easiest way to obtain that.

There are many ways that you can accomplish this; but one of the simplest is to have a delegate respond to your change.

You can't generate it, one has to request it. The API-key of LinkedIn can be obtained here[^].

In general, one generates a unique number (based on a GUID, the date/time and/or a hash of the username) and send that by email. You'd have to keep a list of the email-adresses that match the unique number.

You can then verify the number/emailname combination in your webservice to determine whether the API-key is valid.

So, to define the best practices;

Make sure that the identification-number is unique
Use an emailaddress instead of a username

Hope this helps Smile | :)

You can use Dataset and fill tables in the dataset from different stored procedures, and finally bind the report to the dataset.

protected void btnAdd_Click(object sender, EventArgs e)
{
Response.Cookies["message"].Value = "Hello World";
Response.Cookies["message"].Expires = DateTime.Now.AddDays(1);
btnAdd.Text = Response.Cookies["message"].Value;
Button1.Text = Response.Cookies["message"].Value;

}
protected void Button1_Click(object sender, EventArgs e)
{
if (Response.Cookies["message"] == null)
Button1.Text = "null";
else
Button1.Text = Response.Cookies["message"].Value;
}

when btnAdd)Click is executed it sets Button1.Text = btnAdd.Text = "Hello World";
but when Button1_Click is executed it sets Button1.Text = String.Empty.

Why?

refer the cookie from request object rather than response.

if (Request.Cookies["message"] == null)
			Button1.Text = "null";
		else
			Button1.Text = Request.Cookies["message"].Value;

C# windws- Auto increment font size

leoiser21-Mar-10 23:50

leoiser

21-Mar-10 23:50

I want to get the maximum font size that can fit to a button.I am loading a Button to a panel.its width and height will vary(dynamically based on some calculations).I want to increase to the maximum font size.

For example :- Lets assume that Button size is (100,60) and Text is "AC" (only two letters will come). what should be the maximum font size that can fit in this button. if Button size is (150,250) what should be maximum font size that can fit in this button.

Please advice

Thanks,
Ebin
