RadGrid vs GridView_问答_开发者_运维开发者技术经验分享

I am migrating gridview to RadGrid. I am working on updating my RadGrid rows where I am getting some issues.

I updating Clarify Account Nbr, site id, Quote ID columns in "Inplace" editmode. Lets say before update my values are 200, 300, 400 for columns Clarify Account Nbr, site id, Quote ID. When i click edit button and change the values to 111, 222, 333. when I am debugging my code and trying to see the textbox.text values It is showing the old values(200, 300, 400) not the new values (111, 222, 333). ( I hope you guys are understand my problem). Where I am doing wrong. Please help me.

I saw this link but no use.

In the below code 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 am debugging and pointing to ClarifyAccountNbr, SiteID, QuoteID I am getting older values not new values.( before updating)

Here is my code:

        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;

The bullet-proof approach is to fetch the new data from the column editors as presented on this Telerik demo:

Hope this helps.
