It seems that you must have an id ( integer) for your dataset , an update query and a refresh query using that id.

Even if the id is not visible in the grid. Otherwise the DBGrid behaves eratically.

[wangxuebin]

yes,the dataset have an ID,which is an autoincrement field,has been included in the fields list of the query 's SQL statements.You can test it at :

It is not possible to understand what is going on from what you posted above.

"server unavailable,please try later"

 

It shows that your server side code does not respond before AjaxTimeout interval. Either increase AjaxTimeout or find out why server side operation takes that long.

[wangxuebin]

but I set AjaxTimeout=300000,is 5 minutes.I find that if I post normal text,it often works good, but post texts that contain html tokens ,it offen fails,and popup "server unavailable,please try later"

error.After then,any operations on the browser just get error again.

And before post,I have encode the texts that contain html tokens using js function esacpae.

I don't how you do this and what is content of the post you send, so it is difficult to tell.

Please narrow down your issue to a test case and send a bug report. That's the only way we can help.
