                        <tr>
                            <td width="10%">

                            </td>
                            <td colspan="5" width="90%">

                        </tr>
                        <tr>
                            <td>
                                <asp:Button ID="btnLike" CommandName="isLike" runat="server"
                                    Text="Like" />
                            </td>
                        </tr>
                    </table>
                </ItemTemplate>
            </asp:DataList>

and codebehind is

protected void ArticleRep_ItemCommand(object source, DataListCommandEventArgs e)
        {
            if (e.CommandName == "isLike")
            {
                Response.Write(@"<script language="'javascript'">alert('success.');</script>");
            }
            else
                Response.Write(@"<script language="'javascript'">alert('Error.');</script>");
        }

how to get a button click event for the button inside a datalist?

checkout the above code!!??

Answer 1

Your datalist name is OwnArticle and you are writting Itembound event under ArticleRep_ItemCommand .

This is actual problem. You should write it under OwnArticle_ItemCommand event

So write function as below:

protected void OwnArticle_ItemCommand(object source, DataListCommandEventArgs e)
        {
            if (e.CommandName == "isLike")
            {
                Response.Write(@"<script language="'javascript'">alert('success.');</script>");
            }
            else
                Response.Write(@"<script language="'javascript'">alert('Error.');</script>");
        }

ArticleRep might be your different datalist.
