Description |
|---|---|
|
dwcontrol |
A reference to a DataWindow control, DataStore, or child DataWindow |
|
row |
A value identifying the row you want to test to see if it is selected |
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:
if (rowNumber > 0)
{
if (dw_1.IsRowSelected(rowNumber))
dw_1.SelectRow(rowNumber, false);
else dw_1.SelectRow(rowNumber, true);
