RadGrid vs GridView

I am migrating gridview to RadGrid. I am working on updating the RadGrid rows where some problems arise.

I am updating Clarify Account Nbr, site id, code id columns in "inplace" editmode. Suppose before updating my values ​​are 200, 300, 400 for the Clarify Account Nbr columns, site identifier, quotation identifier. When I click the "Edit" button and change the values ​​to 111, 222, 333. When I debug my code and try to see the textbox.text values, it shows the old values ​​(200, 300, 400), and not the new values ​​(111, 222 , 333). (Hope you guys understand my problem). Where am I doing wrong. Please help me.

I saw this link but not used.

In the code below, if you see

string ClarifyAccountNbr = (editedItem["Clarify Account Nbr"].Controls[0] as TextBox).Text;
string SiteID = (editedItem["Site ID"].Controls[0] as TextBox).Text;
string QuoteID = (editedItem["Quote ID"].Controls[0] as TextBox).Text;

when I debug and point to ClarifyAccountNbr, SiteID, QuoteID. I am becoming old values, not new values. (before update)

Here is my code:

The bulletproof approach is to extract new data from the column editors presented in this Telerik demo:

Hope this helps.
