gridView refresh problem
posted

Hi,

 I have made new discovery, the problem is ig:gridEditing tag. If I have gridEditing in gridView as the following: 

<ig:gridEditing id="#{tab}GridEditing" enableOnMouseClick="single" editMode="cell"

cellValueChangeListener="#{transacBean.onCellValueChange}"  />

 

<ig:columnSelectRow id="#{tab}SelectRow" showSelectAll="true"></ig:columnSelectRow>

 ...

Then the grid will not be refresh.

 

old posting:

 If I use gridView in a regular HTML form:

<form id="idCaseTransactionTestForm" name="CaseTransactionTestForm">

<input type="submit" value="submit"/>

 

<ig:gridView id="idGridView" dataSource="#{transacBean.caseTran}" binding="#{transacBean.gridView}"

selectedRowsChangeListener="#{transacBean.onSelectedRowsChange}"

columnHeaderStyleClass="gridHeader" styleClass="ccTextSytleClass" rendered="true" >

 

..

</ig:gridView>

</form>

 the event handler onSelectedRowsChange() will not be called if you select rows. If the submit button is pressed, the page will be submitted and the view will be refreshed.

Trying to get onSelectedRowsChange() called, I use

<h:form>

<gridView ..../>

</h:form>

 where h:form is of

http://java.sun.com/jsf/html

The event handler onSelectedRowsChange() will be called correctly, but the page will not be refreshed even the backing bean is called, it shows the initial data.

 The problem exists for other ig controls. It doesn't refresh or event handler doesn't got called. Please help.

 Thanks.

    Hi yzbythesea , Attached below is the sample GridView application. In order to refresh grid we need to call 'grid.dataBind()' in our backing bean under action method.

    Thank you!
