• Re: DataValueField not binding to checkboxlist

  I would recommend using an asp:Checkbox, as that will mean that your users have a larger click target (the text as well as the checkbox). Also, you can simplify the HTML by just having a <br /> after your CheckBox, rather than wrapping everything up in a table.

• Re: GridView: Bulk-editing data that contains a vaiable number of columns

  Thanks for the responses Samu. However I have also attempted this approach - it works well for displaying the data, however I encounter the same issue as described in my post: When I am iterating row cells in my save button Click event handler, I am no longer able to obtain a reference to the cell's TextBox. The Controls.Count for the cell is now zero! As far as I can tell, any programmatic manipulation of the Controls collection causes the above issue...unless I am missing something. For the

• Re: setting enableeventvalidation to false

  This might make no difference - how how about placing a Label control inside your UpdatePanel and updating its Text property, rather than setting the inner html of the UpdatePanel? Could you post your aspx file contents here?

• Re: setting enableeventvalidation to false

  Are you setting the inner html property with text, or with HTML markup? Anything like <this> will (I think) upset the ASP.NET event validation stuff. Certainly that's a case if you have this in a textbox text property. Why are you setting the inner html property, and what with? Sounds like a slightly unusual thing to need to do...

• Re: setting enableeventvalidation to false

  I just tested that here - looks like this doesn't cause any issues. (Is there any reason why you're using <b> instead of <strong> by the way?)

• Re: setting enableeventvalidation to false

  You'll need to supply more detailed information about what your doing, and the specifics of the error message in order for anyone else to help... We've done a lot of work recently using the Ajax Control Toolkit and have found quite a few interesting scenarios where event validation errors can be caused. For each one we've been able to figure out a different fix or workaround.

• Re: setting enableeventvalidation to false

  It is strongly recommended that you do not set EnableEventValidation to false . What error are you encountering that is alleviated when you set EnableEventValidation to false?

• Re: How to pass value from parent page to popup page?

  Do you mean a popup in a new browser window (the sort that might get stopped by a browser popup blocker...) or a modal popup using the AJAX Control Toolkit ModalPopupExtender ?

• GridView: Bulk-editing data that contains a vaiable number of columns

  This post is slightly longer than I would like, so thanks in advance to anyone who reads the whole thing! I have attempted to make it as clear and concise as possible. I am binding a GridView to a DataTable. The number of columns in the DataTable is variable, and only known at runtime. I need to display the existing data values to the user using a TextBox for each value, so that the user can edit the values. There should be a single "save" button on the form, which saves any changes entered

• Control suggestions - instead of user uploading .csv file of data

  We are replacing an application used by a small number of internal users for uploading quota of travel tickets to an e-commerce system. Each week, the users upload a .csv file containing ticket quota for a week that is 2 months in the future. Typically there are a small number of changes between the ticket data each week. There are about 100 tickets per week. Each ticket contains about 18 items of data. This is a somewhat error prone process for the users, and after they have uploaded the data they
