Removing Horizontal Scroll from Telerik RadComboBox

By Tom Hundley on 6/13/2009 7:54 PM

If you have a rad combo box and the dropdown width is larger than the width, you'll get the annoying horizontal scroll bars. You can fix this in css by using the "!important" tag. Thanks to Telerik support for this fix:

.rcbScroll
{
overflow-y: auto;
overflow-x: hidden !important;
}

Removing a Column from Telerik RadGrid at Runtime

By Tom Hundley on 11/7/2008 9:38 PM

If you need to remove a column from a Telerik RadGrid at runtime, subscribe to the grid's DataBound event, find the column by its unique name, and set its display property to false. This is the correct way to do this without breaking the filter functionality. For a long time I was subscribing to the grid's ItemDataBound event and hiding each dataitem for the column- only now did I realize that the filter was broken by doing it that way.

Example

    protected void rgPartDispositionHistory_DataBound(object sender, EventArgs e)
    {
        rgPartDispositionHistory.MasterTableView.Columns.FindByUniqueName("PeopleSoftId").Display = isTwtc;
    }

ASP.Net Password Complexity RegEx

By Tom Hundley on 9/2/2008 11:15 AM

The "out of the box" password complexity requirements for the ASP.Net Membership system is this:

7 characters minimum 1 symbol character A client asked for a more complex password (a common request):

8 characters minimum at least 1 number at least 1 lower case at least 1 upper case at least 1 symbol character I tested a lot of regular expressions and most of them didn't work. I finally found one that works well:

^.*(?=.{8,})(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[\W]).*$

Simply set the "passwordStrengthRegularExpression" attribute of the provider section in the web.confg to this regular expression and badda bing, you're good to go. See this link for a list of all the attributes in the config.

You might want to seriously look into using the Password Strength Ajax Extender available from the Ajax Toolkit. It's really nice and goes a long way to solving your users' password complexity woes. It's simply to use and you can implement...

Telerik Grid for ASP.Net Ajax: Selecting Page and Row after Insert

By Tom Hundley on 7/8/2008 3:55 PM

The Telerik RadGrid automatically goes to the last page of the grid when inserting records, which is fine you don't care about seeing the newly inserted item. This code will show you how to select the page and row which was just created. The commented code at the bottom will also show you how to open the record in edit mode in cases where you need the page opened in such a manner.

Simply subscribe to the PreRender event of the grid, enumerate the datasource directly to get the new records row index so that you can determine the page index and there you go. Note that the Items collections on all of the grid objects only have the total number of items in that page, which is why you need to enumerate the datasource.

        if (Session[sessionObjectToFind] != null)         {             Guid storeRefId = new Guid(Session[sessionObjectToFind].ToString());             Session[sessionObjectToFind] = null;

            int pageIndex = 0;             int rowIndex = 0;

            for...

Enable Remote HTTP Testing of Webservices

By Tom Hundley on 6/15/2008 12:26 AM

Remote testing of web services via HTTP was diabled by default after .Net 1.0, so now you can only invoke test methods with your browser on the server. Should you ever find the need to enable it again, add the following to the system.Web section of your web.config:

webServices> protocols> add name="HttpPost" /> add name="HttpGet" /> protocols> webServices>
