.aspx.cs file

  protected void checkbox2_checkedchanged1(object sender, eventargs e) {     checkbox chk = (checkbox)sender;     gridviewrow gridrow = ((gridviewrow)(chk.parent));     if (chk.checked)     {         button btn = (button)(gridrow.findcontrol("button"));         btn.enabled = true;     }     else     {         button btn = (button)(gridrow.findcontrol("button"));         btn.enabled = false;     } }

try using below code:

aspx code gridview1:

<asp:sqldatasource id="sqldatasource1" runat="server"          connectionstring="<%$ connectionstrings:email_notificationconnection %>"          selectcommand="select [customer_name] [customer]"></asp:sqldatasource>     <asp:gridview id="gridview1" runat="server" autogeneratecolumns="false"          datasourceid="sqldatasource1" enablemodelvalidation="true">         <columns>             <asp:boundfield datafield="customer_name" headertext="customer_name"                  sortexpression="customer_name" />             <asp:templatefield>              <itemtemplate>             <asp:checkbox runat="server" autopostback="true" id="non_prod_all_select" oncheckedchanged="checkbox2_checkedchanged1"  />             </itemtemplate>              <headerstyle width="30px" /></asp:templatefield>             <asp:templatefield>             <itemtemplate>                 <asp:button id="button1" runat="server" text="button" enabled="false" />             </itemtemplate>         </asp:templatefield>         </columns>     </asp:gridview>

code behind (for checkbox check changed event handler):

protected void checkbox2_checkedchanged1(object sender, eventargs e)         {             foreach (gridviewrow row in gridview3.rows)             {                 ((button)row.findcontrol("button1")).enabled = ((checkbox)row.findcontrol("non_prod_all_select")).checked;              }          }

changes made:

1.set autopostback checkbox true.

2.removed button field , added template field button in third column of grid (so asp:button control read in code behind)

3.changed code behind code necessary.

note: have checked code locally , working expected. replace old code , let me know in case of issues.
