your grid columns in aspx this: -

<columns> <asp:templatefield headertext="column1">     <itemtemplate>         <asp:placeholder runat='server' id="column1placeholder"></asp:placeholder>     </itemtemplate> </asp:templatefield> <asp:templatefield headertext="column2">     <itemtemplate>         <asp:placeholder runat='server' id="column2placeholder"></asp:placeholder>     </itemtemplate> </asp:templatefield> </columns> 

your rowdatabound event this: -

public void gridview_rowdatabound(object sender, gridviewroweventargs e) {     if (column1needscontrols)     {         placeholder placeholder = e.row.findcontrol("column1placeholder") placeholder;         textbox textbox1 = new textbox();         placeholder.controls.add(textbox1);     }      if (column2needscontrols)     {         placeholder placeholder = e.row.findcontrol("column2placeholder") placeholder;         textbox textbox1 = new textbox();         placeholder.controls.add(textbox1);     } }
