primefaces：可编辑数据表中的不可编辑列

Question

I have an editable dataTable, I want to add checkbox to the header which controls the editable mode of the column. which mean, every column has a checkbox in it's header, if the checkbox is selected the columns will be uneditable, which means we can not edit any data in the cells.

how can I do that ??

thanks

Answer 1

Create a variable of type boolean for each column

 <p:selectBooleanCheckbox  value="#{Yourbean.EditableColumn1}" />
 <p:selectBooleanCheckbox  value="#{Yourbean.EditableColumn2}" />
 <p:selectBooleanCheckbox  value="#{Yourbean.EditableColumn3}" />

Let's say you want to have inputText boxes in your column values, you may control if it's editable by the disabled attribute.

 <p:dataTable>
   <p:column id="column1">
      <h:inputText disabled="#{YourBean.EditableColumn1}">
   </p:column>
   <p:column id="column2">
      <h:inputText disabled="#{YourBean.EditableColumn2}">
   </p:column>
   <p:column id="column3">
      <h:inputText disabled="#{YourBean.EditableColumn3}">
   </p:column>
 </p:dataTable>
