I have a form that allows users to post text to a MySQL database using an OdbcConnection. Everything works great until a user entered unicode characters into the textbox and sends the data. Suddenly the page freezes and is not redirected to the next page as programmed. When I check the database later it comes up with all of the users data intact, including the unicode characters. I've duplicated this problem several times by entering unicode characters and then entering only ASCII. It happens every time unicode characters are used. Is the problem on the ASP.Net side or the MySQL side? Here is my code. The description string is from a textbox entered on the form.I thought about using a RegEx to get rid of any non-ascii characters before sending the data. Is that recommended? How do I do it?

Am I going to have to store this in a separate column in another table, or is there a way to tell the provider to accept those characters...

My GridView is bound to a sql data source and allows editing of fields. Coding is in C# and JavaScript.
Using Visual Studio 2008 in test mode, if I enter a less-than "<" or greater-than ">" character in a GridView textbox an error is immediately thrown upon pressing enter:
"Microsoft Visual Studio Mirosoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status dode returned from the server was: 500"
When the < or > is entered in production, the page aborts and loads the application start page.
I need to be able to catch and replace those characters BEFORE the error is thrown. I've tried hooking OnTextChange code to the textboxes, but the error is thrown as soon as I press enter...the OnTextChange code never runs.
I gave an option to user to change password but the text boxes are taking - / @ (special characters). How to check at runtime that user may not enter these characters?

View 3 RepliesI have a dropdownlist which I dynamically select a list item using findbytext as long as there are no special characters. One entry in the list starts with a percent symbol which I have been unable to dyncamically select. I have confirmed that there are no spaces in the list item and have hard coded the query with the string to try to find the problem. FindByText("% Increase") I believe it has something to do with the special character but have been unable to identify a method to work around this.

ddlColumns1.Items.FindByText(strDefault).Selected = True

I'm builing a websight and has encountered an anoying problem. I'm using a gridview and and in the "gridviewRowDataBound" I placed this code:
foreach (TableCell cell in e.Row.Cells)
{
cell.ToolTip = cell.Text;
}
the problem is that the tooltip dosn't show some special charactes and since the websight is for swedish users the "Å,Ä,Ö, é" characters is replaced with other special characters and numbers. If i place a tooltip on a button or other elements the tooltips are displayed properly. Does anybody know how to fix this.
