row |
A value identifying the row you want to test to see |
Return value
Returns true if row in dwcontrol is selected and false if it is not
selected. If row is greater than the number of rows in dwcontrol or is 0
or negative, IsRowSelected also returns false.
Usage
You can call IsRowSelected in a script for the Clicked event to
determine whether the row the user clicked was selected. With
IsRowSelected and SelectRow, you can highlight a row on the client without
causing a postback.
Examples
This code calls IsRowSelected to test whether the clicked row is
selected. If the row is selected, SelectRow deselects it; if it is not
selected, SelectRow selects it:
|
1 2 3 4 5 6 |
if (rowNumber > 0) { if (dw_1.IsRowSelected(rowNumber)) dw_1.SelectRow(rowNumber, false); else dw_1.SelectRow(rowNumber, true); } |
