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 Hans Kristian,

The problems has been solved,Thank you very much!

Hi  Hans Kristian ,

I am glad to hear that you can replicate  my issue,and this problem is emergency for our project ,is there having any temporary method to solve this problem? The premise is the caption is in Chinese...waiting for you reply..thank you!

sorry,there' something wrong, I sent it again for you .

I know in just simple grid scene.it didn't make errors,but in this scene it did.The scene is when expand the treeview node,when the treeview node is the bottom of the node that has no childnode,and its node name is"非球面",the node will trigger a server side button events, the events would bind a datasouce to webgrid.when click the node(非球面),the grid has data now.the problem is that when I set the grid caption in Chinese,it excute successful,but when I click one grid  column to sort, it cuase error and it can't expand the other eclapse node(the document has discribed ) ,but when the grid caption is in English, it didn't cause errors,everything is OK,but our project should show Chinese in the UI, so we don't know how to solve this problem.

In my PC,the project is running OK,now I will send you another sample(ftp://211.101.1.108/customer/project_24733.zip),in this sample,you should do something first:You should see the document first,and enter the project WebContent\Login.aspx.cs to modify database connection string,then add an exist project(a.mdf is which contains in the package I sent to you  )in App_Data file.The last thing you should do is executing the project just in Login.aspx.

I wonder if  this may be the compatibility problem.....
