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

function DeleteRow() {

// Row deletion needs to be allowed

igtbl_getGridById("UltraWebGrid1").AllowDelete=1;

// Get the first row in the grid

var row=igtbl_getRowById("UltraWebGrid1r_0");

// Delete the first row in the grid

igtbl_deleteRow("UltraWebGrid1","UltraWebGrid1r_0");

// Create a counter for the row id

var cnt=0;

// Create a loop, if the row has a next sibling
then we need to delete it

while(row.NextSibling!=null) //在这步，row.NextSibling总是为Undefined类型。以致不能删除行

{

// Increment the counter for the next
rowID

cnt+=1;

// Get the row current row using the name of
the grid and the row

// number from our counter so we can check it
for a sibling

row=igtbl_getRowById("UltraWebGrid1r_"+cnt)

// Finally delete that row,

igtbl_deleteRow("UltraWebGrid1","UltraWebGrid1r_"+cnt);

}

}

//可用的例子

function DeleteRow() {

var grid =
igtbl_getGridById("<%=
uwgList.ClientID % >");

var grna=document.getElementById("<%=uwgList.ClientID %>").name;

var rowsLenght = grid.Rows.length;

for (var i = 0; i
< rows.Lenght; i++){

igtbl_deleteRow(grna,grna+"_r_"+i);

}

}
