the webgrid can't execute succeed after a long time

Hi su su,

I couldn't replicate your issue here. This problem might happen because WebGrid couldn't communicate to server. But based on issue that you described above, I assume that WebGrid maybe refresh its data continously or some code might request to server continously. If possible, could you send us a simple sample that can replicate your issue in our local end or maybe you can explain us the scenario that you want to achieve? I also attach my sample here to show you how to make interaction between 2 WebGrids. Hope my sample can help you to achieve your scenario. Look forward to hear any feedback from you so I can help you further.

Regards,
Bernard

Hi Bernard,

First ,the connection between server and database is sure established successfully,because at first ,the data can display successfully. But after a little long time,it cause error.

Second , I can't find I used Unbound mode in my project,the binding I use is like this in WebGrid1_InitializePostBack events:

WebGrid2.DataSource = dt;

WebGrid2.DataBind();

txt_iid.Text = key;

WebGrid1.ClientAction.RenderControl(txt_iid);

WebGrid1.ClientAction.RenderControl(WebGrid2);

Could you please give me a hand?

Hi su su,

This problem might be happen because the connection from server to database cannot established. Please ensure the connection between your website to your database has been has been successfully configured.

This problem also happen in WebGrid Unbound mode. When WebGrid Unbound mode do FlyPostBack, it would show this error message because WebGrid Unbound mode won't find the database. Hope this helps.

Bernard
