Hi,
i have hidden variable which is update when the row is selected in GridView, and i need this value in java script, we are trying to modify in igf_grid.js
this.selectRow=function(domNode,select){
......}}this.customFLT()};
in the customFLT() method just i am tring to print value using alert(of javascript) method, which works fine and i am able to see the value i have seleted from GridView, and i have to use this variable to some other method, when i removed the alert method than i am not able to get the selected value. if i add alert method than its works fine. and i have set " immediate="true" " of hiddenvariable in JSF.
please let me know what is causing this problem.
thanks in advance.

HI,
i guess the hidden variable is not updated, and if put alert message i hope it will take some time to display and click ok, so in the mean time the hidden variable getting update. if this is case what could be answer.
Hi, dayanandabv!
I'm affraid that the information send is not enough for me to reproduce the scenario. I'll try to think of some solution if you provide me with more detailed information, e.g. parts of your source code and also an explanation of what the idea of this hidden variable is.
Regards!

ig.onPartialRefreshDefault(httpReq);
};
I hope this will help you. Yet I think this topic has gone a little bit farther than the purpose of this forum supposes since this is functionality not provided with our product and involves modifying files that should not be modified. For those aims customers are supposed to submit feature requests.
HI Bozhidar Dedov.
thanks for your replay, i appreciate your continues help.
has you told i have changed the following code according to your suggestion, but it is not working.
is there anything else i need to change? in backing bean? or in design i.e. in JSP design ?
this.selectRow=function(domNode,select){var row=this.getTargetRow(domNode);if(!ig.isNull(row)){if(select){row.select();}else{row.unselect();}var grid=this.getGrid(domNode);if(!ig.isNull(grid)&&grid.isImmediateRowsChangeEvent()){ig.smartSubmit(grid.elm.id,null,null,null,this.customFLT);}}};this.customFLT=function(httpReq){ ig.onPartialRefreshDefault(httpReq); alert("hello"); var value = document.getElementById("form1:hiddenField1").value; alert(value); };
I just added this line ig.onPartialRefreshDefault(httpReq); into the igf_grid.js file at the place shown. I did not change anything else.
Hi Bozhidar,
is it working for you? for me it is not working, so that's what i asked is there anything i need to change?

I think I was clear but if not it is probably my fault. Let me explain again what I am doing to reproduce your sample. Since I necessarily don't have all your classes, I made a simple application realizing the functionality you describe, namely to select a value selected from a WebGrid row in a message box. For that aim I have a JSP page with WebGrid and a hidden field. The WebGrid sends a SelectedRowsChangeEvent that is being caught by a listener method where I added your code. In the igf_grid.js file I replace the Infragistics code in the this.selectRow = function(domNode, select) with your customer code and I made the necessary changes (described so far) so that the value of the hiddenField element displayed in the message updates (this was also explained). This configuration works as it is supposed to.
I will now apply all my source code:
JAVA BackingBean:
GridView grid;
List clientsList = DAO.getClientsList(); // adding some objects
HtmlInputHidden hiddenField1;
}
public void onChangeSelection(SelectedRowsChangeEvent e) {
String selectedid = "";
if (getGrid() != null) {
Iterator selectedRows = getGrid().getSelectedRows()
.iterator();
while (selectedRows.hasNext()) {
RowItem rowItem = (RowItem) selectedRows.next();
{
int i = 0;
Iterator iter = (Iterator) rowItem.getCells().iterator();
while (iter.hasNext()) {
UIComponent cell = (UIComponent) iter.next();
Object object = cell.getChildren().get(0);
if (object instanceof UIOutput) {
if (i == 0) {
String selectedUnit = ((UIOutput) object)
.getValue().toString();
selectedid = selectedid + selectedUnit;
i++;
getHiddenField1().setValue(selectedid);
SmartRefreshManager srm = SmartRefreshManager.getCurrentInstance();
srm.removeSmartRefreshIds(getHiddenField1().getClientId(
FacesContext.getCurrentInstance()));
srm.addSmartRefreshId(getHiddenField1().getClientId(
getHiddenField1().setImmediate(true);
System.out.println("getHiddenField1---> "
+ getHiddenField1().getValue());
public GridView getGrid() {
return grid;
public void setGrid(GridView grid) {
this.grid = grid;
public List getClientsList() {
return clientsList;
public void setClientsList(List clientsList) {
this.clientsList = clientsList;
public HtmlInputHidden getHiddenField1() {
return hiddenField1;
public void setHiddenField1(HtmlInputHidden hiddenField1) {
this.hiddenField1 = hiddenField1;

</html>
Changes in igf_grid.js:
Replace the following code
var row = this.getTargetRow(domNode);
row.select();
row.unselect();
if (!ig.isNull(grid) && grid.isImmediateRowsChangeEvent()) {
this.selectRow = function(domNode, select) {
if (!ig.isNull(row)) {
Please, for further help consult our support policies. Thanks in advance!
HI Bozhidar,
as i am not doing any mistake, let me compare with your demo code.
can you please send your demo code to my mail id or you can just add it here, or shall i send all the nessarry files to you?
thanks
