HI,

You can do this. Create an attribute inside the same table node of type boolean. bind the attribute to the read only property of all your columns. In your Onselect event of the table get the selected element reference using get_lead_selection method. from the element referenc get all the values --> change the attribute value as space (to make it as editable) and set the values again in the row.

Hope this explains..

Thanks

Hi,

For all the Table Columns, create two variants. One with TextView and other with Inout field. Initially keep the variant as Text View. On the event handler for button, Just get the selected row and change the variant to Input field. In this way you can make the row editable.

Steps for variants.

1. Add an attribute of type string to the context node binded to table. say VARIANT.

2. Add two variants as explained above for each table Column  and add elements TextView and Input Field to them respectively. Assign different 'variant key' for both the variants. Say TXT for TextView Variant and INP For Input Field Variant

3. Bind SelectedCellVariant Property of the table column with the attribute VARIANT created above.

4. In WDDOINIT set the attribute VARIANT of all the elements of the node as TXT

5. On button click set the attribute VARIANT of the selected element as INP.
