Simple Form w/ Edit Button

I want to build a form where each entry field is either pre-populated
with data from SQL and 'Read Only' (doesn't have to be 'readonly'
strictly speaking but I don't want it to be editable, like a textbox
that's disabled or a label) with an 'edit' button next to the field that
makes it editable, or if there is no data for the field, have it be an
editable textbox.

The wrinkle is that I want the 'edit' buttons
to work client-side. I've tried javascripts that toggle the 'readonly'
attribute of textboxes, (which I couldn't make work) and I've tried
javascripts that enable/disable the textboxes (which also didn't work).
Someone the problem I had with these first two approached were with
poastback. I want to retrieve the value from each field whether it's
been edited or not at postback, and I want the value to return as
whatever it has been changed to after postback. I had trouble with
both.

I've even tried having two controls, a label and a textbox,
with linked values where only one of the two is ever visible. I had
trouble getting this approach to render correctly using client-side
code.

Is there an approach that is 'best practice' or that most people use for this?

Thanks.

[Solved] Parse out Text in DataField value of GridBoundColumn

Can I modify the Display text value of DataField value of GridBoundColumn ?
I have "4-code"
and need to display just "Code"

Seems like there should be in-house property to handle this rather than in the data retrieval or the subsequent JavaScript display.

RadGrid NestedViewTemplate javascript runtime error

Hello,



I created a simple RadGrid with a NestedViewTemplate and a SqlDataSource1, no code behind involve.  When I click

 expand link and show the static text inside the NestedViewTemplate, I get javascript runtime error:

If above code added to a RadControlWebApp project, it is running fine.  But if it added to a existing ASP.NET

 Web Forms Application. Also, I made sure that Telerik.Web.UI and Skins are added to references and web.config



What am I missing here to make NestedViewTemplate to work? It stopped working in Q3 2013 after upgraded.



Thanks in advance

Partial Match

Hi All,

I've implemented the following functionality in my RadGrid:
http://www.telerik.com/help/aspnet-ajax/grid-google-like-filtering.html

It works well, but it appears to auto-fill the entire value when a user would like to select a subset. For example, if we have days of the week in the ComboBox the user would like to be able to type "sday" and get Wednesday and Thursday back. Is this at all possible?

Thanks,
Mark
