在客户端删除UltraWebGrid的所有行

有时需要在客户端上删除某个UltraWebGrid中所有的行，而如果按照帮助文件中例子的方法来操作的话，是无法删除行的。经询问NetAdvantage工程师，给出一个能用的例子。

//帮助中的例子，不可用

1. function DeleteRow ( ) {
2. // Row deletion needs to be allowed
3. igtbl_getGridById ( "UltraWebGrid1" ). AllowDelete= 1;
4. // Get the first row in the grid
5. var row=igtbl_getRowById ( "UltraWebGrid1r_0" );
6. // Delete the first row in the grid
7. igtbl_deleteRow ( "UltraWebGrid1", "UltraWebGrid1r_0" );
8. // Create a counter for the row id
9. var cnt= 0;
10. // Create a loop, if the row has a next sibling then we need to delete it
11. while (row. NextSibling != null ) //在这步，row.NextSibling总是为Undefined类型。以致不能删除行
12. {
13. // Increment the counter for the next rowID
14. cnt+= 1;
15. // Get the row current row using the name of the grid and the row
16. // number from our counter so we can check it for a sibling
17. row=igtbl_getRowById ( "UltraWebGrid1r_"+cnt )
18. // Finally delete that row,
19. igtbl_deleteRow ( "UltraWebGrid1", "UltraWebGrid1r_"+cnt );
20. }
21. }

//可用的例子

1. function DeleteRow ( ) {
2. var grid = igtbl_getGridById ( "<%= uwgList.ClientID % >" );
3. var grna=document. getElementById ( "<%=uwgList.ClientID %>" ). name;
4. var rowsLenght = grid. Rows. length;
5. for ( var i = 0; i < rows. Lenght; i++ ) {
6. igtbl_deleteRow (grna,grna+ "_r_"+i );
7. }
8. }
