Try this,

Modify Checkbox in Gridview like,

XML

<asp:TemplateField HeaderText="View">
<ItemTemplate>
<asp:CheckBox ID="chkview" runat="server" AutoPostBack="true" OnCheckedChanged="chkview_CheckedChanged" />
</ItemTemplate>
</asp:TemplateField>

And on Code view define,

C#

protected void chkview_CheckedChanged(object sender, EventArgs e)
{
     //Define your code here.
}

Solution 2

Use

C#

<asp:checkbox id="CheckBox1" runat="server" oncheckedchanged="CheckBox1_CheckedChanged" xmlns:asp="#unknown" />

and then try

C#

protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
{
CheckBox chk = (CheckBox)sender;
GridViewRow gr = (GridViewRow)chk.Parent.Parent;
lblmsg.Text = GridView1.DataKeys[gr.RowIndex].Value.ToString();

//lblmsg.Text = "Hello";
}

Multiple controls with the same ID 'CheckBox1' were found. FindControl requires that controls have unique IDs.
