I have a table whose source is some RD.Now suppose I have 10 records in that table and on click of 2nd row (Select button) , I want that it will capture one particular column's value (highlighted in yellow) from the selected row and store it in some property.
Your first challenge would be to allow user to select only one radio button in the table. To achieve this you will have to call a DT whenever a radio button is selected. In this DT you will have to iterate through all the rows and clear any radio button which is already marked selected (pySelected for all other rows except the one in which you have selected should be set to false).
Secondly you want to fetch the value of a column of the row in which the radio button has been selected. So in the same DT (mentioned above) you can again iterate through the list and for the index value where pyselected is "true" get the value of that particular column and do a "set" for the property in which you want to set the value of that column.
