Are you running under Debug mode? Usually I get that debugger error when I'm debugging an app built in Release mode.
In any case, if all else fails, just print the exception details to the output window via Debug.WriteLine. (Or perhaps its as easy as gareth says, and it's just that your event has no listeners.)

If (eventName != null)
new eventName();

Hi all,
Just now I ran into a problem concerning the datagrid and it's row selection.
Currently I'm using the datagrid to select a whole bunch of data from a database. When I click a row it opens a new window with
e.Item.Attributes.Add("onclick", "window.open('whateverpage.aspx?action=id="((DataRowView)e.Item.DataItem).Row["id"].ToString()')"
this (well not exactly that but thats not the point) is included in the datagrid's itemcreated handler.
The datagrid's datasource is a table from the database as to auto generate the columns ( must auto generate btw) and I add a buttoncolumn code-wise.
Now the problem is when I click the button it first handles the row selection, and as such it opens up the new window, which I want to avoid. After all this it finally handles the button, which works fine.
So how do I disable the onclick event ( the row event) for the button column, or I guess any way to avoid the new window popping up is appreciated.
I hope this is possible, if it is not, an acceptable work around would be to close the new window from the button handler ( from the old page)... but I haven't been able to figure out how to do that, since I don't know how to close the new window from the old one or how to pass a (session) variable to the new window before the page loads.
So to clarify , I have a datagrid with selectable rows and a button column. When one selects the button from the buttoncolumn it also selects the row and thus opens a new window before the button is handled.
Hopefully this is enough information to solve the problem, please let me know if I should post additional info to clarify the problem.
Thanks in advance!!

Hi,
I would like to round a decimal number and assign it to string:
so a decimal number such as 8.54 becomes 9
8.2 becomes 8
...
Present code:
ys.YAS_BOND_PX = dp.Value.ToString();
to round up something like as follows:
ys.YAS_BOND_PX = Math.Round(decimal.Parse(dp.Value.ToString()));
Error is :
Cannot implicitly convert type 'decimal' to 'string'
How do I solve this please?
Thanks

Is ys.YAS_BOND_PX a string? If so, that's your problem. Math.Round returns a decimal so you'll need to add a .ToString() at the end to convert it.

You take the value, convert it to a string, parses is as a Decimal, rounds it, and try to put the Decimal value in a string property?
I think that this is what you are trying to do:
ys.YAS_BOND_PX = Math.Round(dp).ToString()
By the way, don't use the Decimal data type unless you really need it's precision (e.g. monetary applications). The natively supported data type preferred for regular floating point numbers is Double.
Despite everything, the person most likely to be fooling you next is yourself.

Hi,
I am using following line of code in a for loop to populate a multiline textbox.
this.textBox2.Text = this.textBox2.Text + '\n' +oCompResult.Errors[i].ErrorText.Trim();
I need to show each array item in separate line.But it doesnt happens even if there is a '\n' present.
Pls help.

try:
textBox2.Text += Environment.NewLine + oCompResult.Errors[i].ErrorText.Trim();
You'd be better off using a StringBuilder for this and setting the textBox2.Text after the loop. Simple example below...
string[] sArray = { "a", "b", "c" };
StringBuilder sBuilder = new StringBuilder();
foreach (string thisString in sArray)
{
sBuilder.AppendLine(thisString);
}
textBox2.Text = sBuilder.ToString();

since your output is line oriented, you should consider a ListBox instead of a TextBox;
it does not need the concatenation of all strings, just a simple
this.ListBox1.Items.Add(oCompResult.Errors[i].ErrorText.Trim());
would do it for whatever number of lines you have, without a quadratic performance hit.

thanks for help.
Luc, if I use list view, it will lead to flicker problems on resizing so I cant use that.

I suggested a ListBox, not a ListView.
I don't recall having seen any flickering ListBoxes yet.
