How can I make a messagebox or textbox pop up when a specific cell is double clicked in my DataGrid in C# WPF -


i have datagrid, i'm using c# wpf. want find way when user double clicks cell in last column textbox pops , displays of content in specific cell. there anyway possibly this? think there way

if (mydatagridobj.cellselected[i] in column)

{    stuff }

i want give content of specific cell when user double clicks on specific cell. don't wwant pop though unless specific cell falls under column name , clicked. want give cell's content.

  1. we need handle mousedoubleclickevent cells.
  2. check if double-click happens in our desired cell.
  3. then need show textbox on our grid cell's data.
  4. if click anywhere on our grid outside textbox, textbox should hidden.

in example, double-clicking last column address column, textbox displayed.

below code can used :
