A problem exists in the smartgridview control emptydatatemplate.

The smartgridview control is used in the project. When binding data, if the data shows "no data" as a fantasy, it is directly bound with data.

Source codeAs follows:

Bind data in the background

Dataset DS =Whbll. checkhistory (historymodel );If(DS =Null| Ds. Tables. Count <=0| Ds. Tables [0]. Rows. Count <=0) {Datatable dt=Createtemptable (); grid_histroy.datasource=DT; grid_histroy.databind ();}Else{Grid_histroy.datasource= Ds. Tables [0]; Grid_histroy.databind ();}
 

After running the page, you will find that there is a problem with the page style.

Debug with Firefox and find the following style:

We can see that there is one more line, as shown in blue,
