gridView refresh problem

Yan posted over 15 years ago

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:

<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>

</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, We are glad sample application worked for you. Yes!! We can definitely refresh grid from any of the functions in the backing bean. Greatly appreciate if you could log to ‘Support Requests’ and please provide us an isolated sample application. We shall provide solution at the earliest.

Note: DataBind() could be also applied to any other Infragistics components i.e. Tree, Menu etc.

Also, Please visit below link containing many interesting and challenging sample applications (NetAdvantage for JSF) with source code.

Hi Swatha,

I tried your approach and it worked!

It seems to me DataBind() is powerful function. Can I refresh grid from backing bean by using DataBind() or other functions? In my case, the backing can be called to other function asking to refresh grid with some new data. I have not found a way to do it.

Thanks a lot.

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!
