checkbox in grid

Question

In the itemtemplate of a web datagrid I have placed a checkbox. At present for every row of the grid there is a checkbox. If for example let's say three of the records have the same FileID then I would like to have only one checkbox for these three rows as opposed to one checkbox for each row. How can I do this please? Thanks

I would go for something like: And in the codebehind: private Int32 lastFileID; private Boolean fileIDSet = false; protected Boolean IsCheckboxVisible( Int32 fileID ) { // if this method is being called for the first time if ( !fileIDSet ) { fileIDSet = true; // then show the checkbox return true; } // if the fileID has just changed then show the checkbox if ( lastFileID != fileID ) return true; return false; } This is just a suggestion and is not tested but I hope it helps.
