GWT Celltable How to make Non-Editable cell in Editable column

[vaibhav bhalke]

Hi,

I added EditTextCell(stringTestEditTextCell) to Column(testColumn).

 EditTextCell editTextCell = new EditTextCell();
       Column<Record, String> stringColumn = new Column<Record, String>(
                editTextCell) {
            @Override
            public String getValue(Record object) {
             
                return object.getValue();
            }
        };

All cells in testColumn are editable.

 I want 1st cell of column such way that  1st cell of column should be Non-Editable.

you mean 1st column of row to be non-editable or readonly. Use a
TextColumn or use TextCell instead of EditTextCell

Thanks

Hi,

You can create your own cell, in the render method:

public class MyCustomeCell extends EditTextCell {

.......

public void render(Context context, String data, SafeHtmlBuilder sb)
{
if(context.getIndex()==0)
// render your own cell, a div or something... ex: <div>data</
div>
else
super.render(context,data, sb);
}

.......

Thanks Ozgur.

public void render(com.google.gwt.cell.client.Cell.Context context,
String value, SafeHtmlBuilder sb) {

if(context.getColumn()==2 && context.getIndex()==0 ){

sb.appendHtmlConstant("<div contentEditable='false'
unselectable='true'></div>"); // This non-editable cell
// This will work in mozila firefox ? <div
contentEditable='false' unselectable='true'></div>
}else{
super.render(context, value, sb);
}

}
It works fine as per my use case. :)

Now problem is when I am performing pagination then next N-1 page's
2nd_column of 1st cell is editable :|
How can I do it as non-editable on pagination ?
